INSTRUCTION MANUAL HF/VHF/UHF ALL MODE TRANSCEIVER i706MKG This device complies with Part 15 of the FCC rules. Operation is sub-
ject to the following two conditions: (1)This device may not cause harmful interference, and (2)this device must accept any interference received, including interference that may cause undesired operation. IMPORTANT Read this instruction manual carefully before attempting to operate the transceiver. Save this instruction manual. This instruction manual contains important safety and operating instructions for the IC-706MKIIG. PRECAUTIONS RWARNING HIGH VOLTAGE! NEVER attach an antenna or internal antenna connector dur-
ing transmission. This may result in an electrical shock or burn. RNEVER apply AC to the [DC13.8V] socket on the transceiver rear panel. This could cause a re or ruin the transceiver. RNEVER apply more than 16 V DC, such as a 24 V battery, to the [DC13.8V] socket on the transceiver rear panel. This could cause a re or ruin the trans-
ceiver. RNEVER let metal, wire or other objects touch any internal part or connectors on the rear panel of the transceiver. This will cause electric shock. RNEVER expose the transceiver to rain, snow or any liquids. NEVER allow children to play with the transceiver. AVOID using or placing the transceiver in areas with temperatures below 10C (+14F) or above +60C
(+140F). Be aware that temperatures on a vehicles dashboard can exceed 80C, resulting in permanent damage to the transceivers front panel if left there for extended periods. AVOID placing the transceiver in excessively dusty environments or in direct sunlight. AVOID placing the transceiver against walls or putting anything on top of the transceiver. This will obstruct heat dissipation. EXPLICIT DEFINITIONS The explicit denitions described below apply to this instruction manual. WORD RWARNING CAUTION NOTE DEFINITION Personal injury, fire hazard or electric shock may occur. Equipment damage may occur. If disregarded, inconvenience only. No risk of personal injury, re or electric shock. During mobile operation, DO NOT operate the trans-
ceiver without running the vehicles engine. When transceiver power is ON and your vehicles engine is OFF, the vehicles battery will soon become exhausted. Make sure the transceiver power is OFF before start-
ing the vehicle. This will avoid possible damage to the transceiver by ignition voltage spikes. During maritime mobile operation, keep the transceiv-
er and microphone as far away as possible from the magnetic navigation compass to prevent erroneous indications. BE CAREFUL! The heatsink will become hot when operating the transceiver continuously for long periods. BE CAREFUL! If a linear amplier is connected, set the transceivers RF output power to less than the lin-
ear ampliers maximum input level, otherwise, the lin-
ear amplier will be damaged. Use Icom microphones only (supplied or optional). Other manufacturer s microphones have different pin assignments and connection to the IC-706MKIIG may damage the transceiver. Beat signals may be heard on some frequencies. These will occur as a result of circuit construction. For U.S.A. only Caution: Changes or modications to this transceiver, not expressly approved by Icom Inc., could void your author-
ity to operate this transceiver under FCC regulations. The IC-706MKIIG Europe version complies with essential requirements of the 89/336/EEC direc-
tive for Electromagnetic Compatibility under the conditions listed below. This compliance is based on confor-
mity with the European harmonized standard ETS300 684 Jan. 1997 (EMC product standard for Commercially Available Amateur Radio Equipment). Condition:

HM-103 SCHEMATIC DIAGRAM 8 2 INSTALLATION AND CONNECTIONS n Unpacking After unpacking, immediately report any damage to the delivering carrier or dealer. Keep the shipping car-
tons. For a description and a diagram of accessory equip-
ment included with the IC-706MKIIG, see UNPACK-
ING on p. ii of this manual. n Grounding To prevent electrical shock, television interference
(TVI), broadcast interference (BCI) and other prob-
lems, ground the transceiver through the GROUND terminal on the rear panel. For best results, connect a heavy gauge wire or strap to a long earth-sunk copper rod. Make the distance between the GROUND terminal and ground as short as possible. RWARNING:NEVER connect the [GND] ter-
minal to a gas or electric pipe, since the connection could cause an explosion or electric shock. n Antenna Select antenna(s), such as a well-matched 50 W antenna, and feedline. The transmission line should be a coaxial cable. 1.5 : 1 or better of Vo l t a g e Standing Wave Ratio (VSWR) is recommended for your required band. Of course, the transmission line should be a coaxial cable. CAUTION: Protect your transceiver from lightning using a lightning arrestor. ANTENNA SWR Each antenna is tuned for a specied frequency range and SWR may be increased out-of-range. When the SWR is higher than approx. 2.0 : 1, the transceivers power drops to protect the nal transis-
tors. In this case, an optional antenna tuner is useful to match the transceiver and antenna. Low SWR allows full power for transmitting even when using the antenna tuner. The IC-706MKIIG has an SWR meter to monitor the antenna SWR continuously. INSTALLATION AND CONNECTIONS 2 n Installation D Single body mounting D Stand To raise the stand:
With the transceiver upside down, pull the stand towards the rear panel and then upwards, as illus-
trated below. D Front panel separation
While pulling the panel release button towards you, slide the front panel to the right (g. 1).
` Attach the optional OPC-581 to the main body and tighten the supplied screw as in g. 2. Attach the other end of the OPC-581 to the detached front panel as in g. 3. D Front panel mounting
Attach the MB-63 to a at surface using the two supplied screws (g. 1).
` Fix the detached front panel to the MB-63 as illus-
trated in g. 2. Be careful of the orientation of the MB-63, other-
wise, the front panel may become attached in the opposite direction. 10 2 INSTALLATION AND CONNECTIONS n Required connections INSTALLATION AND CONNECTIONS 2 n Advanced connections 12 2 INSTALLATION AND CONNECTIONS n Power supply connections Use the optional PS-85 DC POWER SUPPLY when oper-
ating the IC-706MKIIG with AC power. Refer to the diagram below for connection. C A U T I O N : Before connecting the DC power cable, check the following important items. Make sure:
The [POWER] switch is OFF. Output voltage of the power source is 1215 V when you use a non-Icom power supply. DC power cable polarity is correct.
: positive (+) terminal Red Black : negative () terminal Note: When using the PS-85, the IC-
706MKIIG Europe version complies with EMC directives even if the OPC-639 is not used. INSTALLATION AND CONNECTIONS 2 n External antenna tuners and linear amplier Note:
Turn the IC-706MKIIGs power OFF when connecting the AT-
180, otherwise, the CPU may malfunction and the AT-180 may not function properly. The OPC-742 is required when using both the AT-180 and a 2 m linear amplier. Do not connect [ANT 2] to the AT-180. When using an HF to 2 m wide antenna, use a duplexer between the AT-180 and antenna since 2 m signals do not pass through the AT-180. 14 3 FREQUENCY SETTING n When rst applying power (CPU resetting) Before rst applying power, make sure all connections required for your system are complete by referring to section 2. Then, reset the transceiver using the fol-
lowing procedure. Note: Resetting clears all programmed contents in memory channels and returns all initial set mode and quick set mode contents to their default values.
Make sure the transceiver power is OFF.
` While pushing [Y] and [Z], push [POWER] to turn power ON. The internal CPU is reset. The transceiver displays as shown at right when reset-
ting is complete. D M1 display selection If you cant gure out how to return to the M1 display:
While pushing [MENU], turn power ON. n Initial settings After resetting the transceiver, set controls and switch-
es as shown in the diagram below. CCW: counterclockwise Turn power ON, then check the display. If any of the following indicators appear, turn them OFF as follows:

FREQUENCY SETTING 3 frequency and operating mode for operation. n VFO description VFO is an abbreviation of Variable Frequency Oscillator, and traditionally refers to an oscillator. The IC-706MKIIGs VFO can store a frequency and an operating mode. You can call up a desired frequency to a VFO with the memo pad-read switch (p. 41) or with the memory transfer switch (p. 41). You can also change the fre-
quency with the main dial and select an operating mode with the [MODE] switch or call up previously accessed frequency and modes with the band stack-
ing register (p. 19). The IC-706MKIIG has two VFOs, specially suited for split frequency operation. The VFOs are called VFO A and VFO B. You can use the desired VFO to call up a The differences between VFO and memory mode VFO MODE Each VFO shows a frequency and operating mode. If the frequency or operating mode is changed, the VFO automatically memorizes the new frequency or operating mode. MEMORY MODE (pgs. 3841) Each memory channel shows a frequency and oper-
ating mode like a VFO. Even if the frequency or mode is changed, the memory channel does not memorize the new frequency or memory mode. When the VFO is selected from another VFO or memory mode, the last-used frequency and operat-
ing mode for that VFO appear. When a memory channel is selected from another memory channel or VFO mode, the memorized fre-
quency and operating mode appear.

[(Y)B A N D ] / [(Z)BAND] continuously scrolls Note: The band stacking register can also be used to select bands. Refer to p. 19. Programmable tuning steps Programmable tuning steps are available to suit your operating requirements. These tuning steps are:
Independently selectable for each mode Selectable from 0.01 (FM/WFM/AM only), 0.1, 1, 5, 9, 10, 12.5, 15, 20 and 100 kHz
Push [TS] one or more times until the programma-
ble tuning step indicator, Z, appears above the 1 kHz digit. Rotating the main dial changes the frequency according to the set tuning step.
` Push [TS] for 2 sec. while the programmable tun-
ing step indicator appears to enter the tuning step selection mode. Rotate DIAL appears. Rotate the main dial to set the desired tuning step. Change the mode and select tuning steps for other modes, if desired. Push [TS] to exit the tuning step selection mode. Rotate the main dial to change the frequency according to the set tuning step. 1 Hz and 10 Hz tuning steps When neither the quick tuning step or programmable tuning step, Z, appear, rotating the main dial changes the frequency in increments of 1 or 10 Hz. These tuning steps are only available in SSB, CW and RTTY modes.
Select SSB, CW or RTTY mode if necessary.
` Push [TS] for 2 sec. to toggle between the 1 and 10 Hz step settings. When the 1 Hz step is selected, the 1 Hz digit appears in the frequency indication; when the 10 Hz step is selected, the 1 Hz digit disappears from the frequency indication. 1 MHz quick tuning step The quick tuning step function allows you to change the frequency in 1 MHz steps when rotating the main dial. This function is only available in FM, WFM and AM modes.
Select FM, WFM or AM mode if necessary.
` Push [TS] momentarily to toggle between the 1 MHz tuning step and the programmable tuning step. Z appears above the 1 MHz indicator when the 1 MHz tuning step is selected. When the 1 MHz tuning step is selected, slow rotation of the main dial changes the frequency in 1 MHz steps and fast rotation of the main dial changes the frequen-
cy in 5 MHz steps. Sub dial function The sub dial function allows you to change the oper-
ating frequency using the [M-CH] control. This gives you more control in tuning since the [M-CH] knob is detentedeach click changes the frequency accord-
ing to the set tuning step. This function is always available in FM, WFM and AM modes. However, in SSB, CW and RTTY modes, the set mode item Sub dial function, must be set to FrEq.
Push [RIT/SUB] to turn the sub dial function ON. The [SUB] indicator lights green; if it lights red, the RIT function is activatedsub dial function must be set in initial set mode in this case.
` Rotate [M-CH] to change the operating frequency according to the set tuning steps. Push [RIT/SUB] again to turn the function OFF. The [SUB] indicator turns off. FREQUENCY SETTING 3 18 3 FREQUENCY SETTING Quick band change function The quick band change function automatically stores the last frequency and mode used for each band in a band stacking register.

[MODE] one or more times, then push [MODE] for 2 sec., if necessary. See the diagram at right for the order of selection. The selected mode is indicated in the function display. Note: If a desired mode cannot be selected, it may be hidden using Initial Set mode (p. 49). RECEIVE AND TRANSMIT 4 n Functions for receive D IF shift function The IF shift function electronically changes the pass-
band frequency of the IF (intermediate frequency) and cuts out higher or lower frequency components of the IF to reject interference. The function shifts the IF frequency up to 1.2 kHz in 15 Hz steps in SSB/CW/RTTY modes and up to 250 Hz in 3 Hz steps in CW-/RTTY- modes. The IF shift is not available in FM and AM modes.
Adjust the [SHIFT] control for a minimum interfer-
ence signal level. The audio tone may be changed while the IF shift is in use.
` Set the shift control to its center position when there is no interference. Graphic display The IF shift is displayed graphically (for about 1 sec.) each time the shift control is rotated. D RIT function The RIT (Receive Incremental Tuning) function com-
pensates for off-frequencies of communicating sta-
tions. The function shifts the receive frequency up to 9.99 kHz in 10 Hz steps without moving the transmit frequency. The [SUB/RIT] switch in Initial Set Mode must be set to RIT mode in advance (p. 50).
Push [RIT]. The [RIT] indicator lights red.
` Rotate the [M-CH] control to cancel the off-fre-
quencies. The transmit frequency is not shifted. To cancel the RIT function, push [RIT] again. The [RIT] switch indicator goes out. Calculate function The shift frequency of the RIT function can be added/subtracted to the displayed frequency. While the RIT indicator is lit, push and hold [RIT] for 2 sec. Note: The RIT function is not available in FM, WFM or AM modes regardless of the Initial Set mode set-
ting (p. 50). 20 4 RECEIVE AND TRANSMIT D Noise blanker The noise blanker reduces pulse-type noise such as that generated by automobile ignition systems. This function is not effective for FM modes or for non pulse-
type noise. If you dont want to use the noise blanker for AM communications, the AM noise blanker item in Initial Set mode must be turned OFF (ON is the default settingp. 52).
Select M3. Push [DISPLAY] 1 or 2 times when S or G is displayed. Push [MENU] one or more times to select M3. D AGC time constant The AGC (Automatic Gain Control) controls receiver gain to produce a constant audio output level even when the received signal strength is varied by fading, etc. Use AGC slow for normal phone operation; AGC fast for receiving data and searching for signals. AGC time constant cannot be changed in FM mode.
Select M4. Push [DISPLAY] 1 or 2 times when S or G is displayed. Push [MENU] one or more times to select M4.
` Push [(F-3) AGC] to toggle the AGC time constant between fast and slow. FAGC appears when the fast time constant is selected. D Preamp and attenuator The preamp amplies received signals in the front end circuit to improve the S/N ratio and sensitivity. Turn this function ON when receiving weak signals. The attenuator prevents desired signals from distort-
ing when very strong signals are near the desired fre-
quency or when very strong electric elds, such as from broadcasting stations, are near your location. INITIAL SET MODE D Peak meter hold The peak meter hold function freezes the highest dis-
played bar segment in any meter function for about 0.5 sec. so that you can more easily read the meter. This function can be turned ON and OFF in initial set mode (see p. 50).
` Push [(F-2)NB] to toggle the noise blanker ON and OFF. NB appears when the noise blanker is turned ON. Push [P.AMP/ATT] momentarily to turn the preamp ON and OFF; push and hold to turn the attenuator ON. Lights green when the preamp is ON; lights red when the 20 dB attenuator is ON. Only one of these functions can be activated at a time. D RF gain and squelch The IC-706MKIIG uses the same control, [RF/SQL], to adjust one of either the RF gain or the squelch.
[RF/SQL] adjusts either the RF gain or the squelch depending on the operating mode selected and the condition of the RF gain item in initial set mode (p. 50; also see the table at right). The RF (Radio Frequency) gain is used to adjust the receiver gain. This control should be set to the 11 oclock position for normal use. Shallow rotation moves the S-meter to the right indicating the signal strength which can be received. The S Q U E L C H removes noise output from the speaker (closed condition) when no signal is received. The squelch is particularly effective for FM. It is also available for the other modes. When operating in FM, rst rotate the control fully coun-
terclockwise. Then, rotate the control clockwise to the point where the noise just disappears. This is the best position. The squelch does not open for weak signals when it is set too deep. A segment appears in the S-meter to indicate the S-meter squelch level. D Simple band scope This function allows you to visually sweep an area surrounding the set frequency for other signals. Detected signals are indicated graphically in the dot matrix section of the display.
Set a mode and frequency.
` Select G1. Push [DISPLAY] 1 or 2 times if M or S appears. Push [MENU] one or more times to select G1. Push [F-1] one or more times to select the desired steps. Each dot corresponds to a step for the indicated fre-
quency. 0.5, 1, 2, 5, 10, 20 and 100 kHz can be set for the scope step. Push [F-3] to start the sweep. ___ (below SWP) ashes while sweeping. The receive audio is muted while sweeping. Rotate the main dial if you want to monitor the dis-
played signals. The sweep marker indicates the location of the dis-
played frequency in the sweep readout. If the displayed frequency is outside of the sweep read-
out (determined by the sweep width), the sweep mark-
er ashes. Push [F-2] to return the frequency to the start of a sweep. The sweep marker moves back to the center position. RECEIVE AND TRANSMIT 4

DISPLAY INDICATION MEASUREMENT Po Indicates the relative RF output power. ALC Indicates the ALC level. When the meter movement shows the input signal level exceeds the allowable level, the ALC limits the RF power. In such cases, reduce
(see above). the microphone gain SWR Indicates the SWR over the transmis-
sion line. Note: The SWR meter cannot be used for the 144/430 MHz bands since the meter activates for the [ANT 1] con-
nector only. 24 4 RECEIVE AND TRANSMIT D Speech compressor The IC-706MKIIG has a built-in, low distortion speech compressor circuit. This circuit increases your average talk power in SSB mode and is espe-
cially useful for DXing when the receiving station is having difculty copying your signal.

During SSB operation on HF bands at low voice lev-
706MKIIG to the connected antenna automatically. els, the AT-180 may not be tuned correctly. In such Once the tuner matches an antenna, the variable cases, manual tuning is helpful. capacitor angles are memorized as a preset point for each frequency range (100 kHz steps). Therefore, when you change the frequency range, the variable capacitors are automatically preset to the memorized point. Push and hold [TUNER] for 1 sec. to start manual tuning. CW mode is selected, a side tone is emitted, and the
[TUNER] light ashes; then, the previous mode is select-
ed. CAUTION: NEVER transmit with the tuner ON when no antenna is connected. This will damage both the transceiver and the antenna tuner. Note:
The AT-180 cannot be used for the 144/430 MHz band. When operating on the 144/430 MHz band, pushing the tuner switch selects the call channel (p. 38). The AT-180 can match both HF and 50 MHz bands. However, operation is different for the HF and 50 MHz bands. TUNER OPERATION For the HF band:
Push [TUNER] to turn the tuner ON. The antenna is tuned automatically during transmission when the antenna SWR is higher than 1.5:1. When the tuner is OFF, the [TUNER] light goes out. For the 50 MHz band:
Push and hold [TUNER] to tune the antenna. If the
[TUNER] light ashes slowly while transmitting, push and hold [TUNER] again to re-tune the antenna. If the tuner cannot reduce the SWR to less than 1.5:1 after 20 sec. of tuning, the [TUNER] light goes out. In this case, check the following:
the antenna connection and feedline the antenna SWR (p. 25; meter function) Through inhibit (HF bands only) The AT-180 has a through inhibit condition. When selecting this condition, the tuner can be used at poor SWRs. In this case, automatic tuning in the HF bands activates only when exceeding SWR 3:1. Therefore, manual tuning is necessary each time you change the frequency. Although termed through inhibit, the tuner will be through if the SWR is high-
er than 3:1 after tuning. CONVENIENT Tuner sensitive condition (HF bands only) If you require critical tuning at any time during trans-
mission, select the tuner sensitive condition. See p. 55 for selection. Automatic tuner start (HF bands only) If you want to turn OFF the tuner under conditions of VSWR 1.5:1 or less, use automatic tuner on and turn the tuner OFF. See p. 53 for turning the function ON and OFF. 26 4 RECEIVE AND TRANSMIT D Optional AH-4 AUTOMATIC ANTENNA TUNER operation AH-4 operation The AH-4 matches the IC-706MKIIG to a long wire antenna more than 7 m / 2 3 ft long (3.5 MHz and Tuning is required for each frequency. Be sure to above). re-tune the antenna before transmitting when you See p. 14 for connection. change the frequencyeven slightly. See the AH-4 instruction manual for AH-4 installation and antenna connection details.
Set the desired frequency in an HF band. The AH-4 will not operate on frequencies outside of ham bands.
` Push and hold [TUNER] for 2 sec. The [TUNER] light ashes and CW appears while tun-
ing. RWARNING: HIGH VOLTAGE!
NEVER touch the antenna element while tuning or transmitting. NEVER operate the AH-4 without an antenna wire. The tuner and transceiver will be damaged. NEVER operate the AH-4 when it is ungrounded. Transmitting before tuning may damage the trans-
ceiver. Note that the AH-4 cannot tune when using a 12 l long wire or multiple of the operating frequency. Note: The AH-4 can be used for HF bands and the 50 MHz band only. The [TUNER] light lights constantly when tuning is complete. When the connected wire cannot be tuned, the
[TUNER] light goes out, the AH-4 is bypassed and the antenna wire is connected to the antenna connector on the transceiver directly. To bypass the AH-4 manually, push [TUNER]. CONVENIENT PTT tune function The AH-4 is always tuned when the PTT is pushed after the frequency is changed (more than 1%). This function removes the push and hold [TUNER] oper-
ation and activates rst transmission on the new fre-
quency. This function is turned ON in initial set mode, item 13 (p. 53). n Split frequency operation Split frequency operation allows you to transmit and receive on two different frequencies. Split frequency operation uses 2 frequencies, one in VFO A and the other in VFO B. Following is an example of setting 7.057 MHz, CW mode in VFO A (for receive) and 7.025 MHz, CW mode in VFO B (for transmit).
Select VFO A and set the frequency to 7.057 MHz/CW.
[ (F-2)A/B] is available when M1 appears.
[(F-3)V/M] is available when M2 appears.
` Push or push and hold [(F-1)SPL] in the M1 dis-
play.
Push [SPL]: activates split only.
Push and hold [SPL]: activates the quick split below. To change the receive frequency, rotate the main dial; to change the transmit frequency, rotate the main dial while pushing [(F-3)XFC]. D Quick split function In M1, when you push [(F-1)SPL] for 2 sec., split fre-
quency operation is turned ON and VFO B is auto-
matically changed according to the plus/minus pre-
programmed shift frequency set in initial set mode (or equalized when 0 kHz is programmed as the split shift frequency). This shortens the time needed to start split frequency operationgreat for DXing. RECEIVE AND TRANSMIT 4 The transmit frequency can be monitored while pushing
[(F-3)XFC]. Split operation is now set for receive on 7.057 MHz/CW and transmit on 7.025 MHz/CW. To exchange the transmit and receive frequencies, push [(F-2)A/B] in M1. CONVENIENT The G3 display conveniently shows the transmit fre-
quency during split frequency operation and [(F-3)]
allows you to change the transmit frequency. Split lock function The split lock function is convenient for changing only the transmit frequency. Otherwise, accidentally releasing the [(F-3)XFC] switch while rotating the main dial changes the receive frequency. The split locks effectiveness can be selected in initial set mode (item 12) for both receive and transmit fre-
quencies; or only the receive frequency. (p. 51) The quick split function is ON by default. If desired, it can be turned OFF in initial set mode (p. 51). In this case, pushing [(F-1)SPL] for 2 sec. has the same effect as pushing [(F-1)SPL] momentarily as in nor-
mal split operation. PROGRAMMING SPLIT SHIFT FREQUENCY
Push [POWER] to turn power OFF.
` While pushing [LOCK], push [POWER] to turn power ON and enter initial set mode. Select SPL OFFSET using [MENU], [M-CH] or the [Y]/[Z] keys, then rotate the main dial to select the desired split offset. The split offset can be selected from 4000 kHz to

D Adjusting the transmit signal output from the TNC
+ NOTE: For packet operation the transceiver can be set to one of two data speeds: 1200 bps or 9600 bps. Data speed is set in initial set mode
(see p. 53 item 29 9600 MODE). Data speed is set in initial set mode (see p. 53 item 29 9600 MODE).When setting data transmission speed to 9600 bps, the DATA signal coming from the TNC is applied exclusively to the internal limiter cir-
cuitry to automatically maintain bandwidth. NEVER apply data levels from the TNC of over 0.6 Vp-p, otherwise the transceiver will not be able to maintain the band width and may possibly interfere with other stations.
+ NOTE: Read the instructions supplied with your TNC carefully before attempting packet operation with the IC-706MKIIG. 1. When using a level meter or synchroscope, adjust the TX audio level (DATA IN level) from the TNC as follows. 0.4 Vp-p (0.2 Vrms): recommended level 0.2 Vp-p0.5 Vp-p (0.1 Vrms0.25 Vrms):

` Push [(F-2)MPW] to program the frequency into a memo pad. When you write a 6th frequency and operating mode, the oldest written frequency and operating mode are automatically erased to make room for the new set-
tings. Note: Each memo pad must have its own unique combination of frequency and operating mode;
memo pads having identical settings cannot be writ-
ten. Calling up a frequency from a memo pad You can simply call up the desired frequency and operating mode of a memo pad by pushing
[(F-3)MPR] in the S1 display. Make sure S1 is selected in advance. Both VFO and memory modes can be use. The frequency and operating mode are called up, starting from the most recently written. When you call up a frequency and an operating mode from memo pads with [(F-3)MPR], the previ-
ously displayed frequency and operating mode are automatically stored in a temporary pad. The fre-
quency and operating mode in the temporary pad can be recalled by pushing [(F-3)MPR] one or more times. Note: If you change the frequency or operating mode called up from a memo pad, the frequency and oper-
ating mode in the temporary pad are erased. MEMORY AND SCAN OPERATION 5 n Scan types n Preparation Channels For programmed scan: Program scan edge frequen-
cies into scan edge memory channels 1A and 1B
