INSTRUCTION MANUAL HF/50 MHz ALL MODE TRANSCEIVER i756PRO IMPORTANT EXPLICIT DEFINITIONS READ THIS INSTRUCTION MANUAL CAREFULLY before attempting to operate the transceiver. SAVE THIS INSTRUCTION MANUAL. This manual contains important safety and operating in-

structions for the IC-756PROII. WORD DEFINITION RRWARNING Personal injury, re hazard or electric shock may occur. CAUTION Equipment damage may occur. NOTE If disregarded, inconvenience only. No risk or personal injury, fire or electric shock. PRECAUTIONS R WARNING HIGH VOLTAGE! NEVER at-

tach an antenna or internal antenna connector during transmission. This may result in an electrical shock or burn. R NEVER apply AC to the [DC13.8V] jack 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] jack on the transceiver rear panel. This could cause a re or ruin the transceiver. R NEVER let metal, wire or other objects touch any internal part or connectors on the rear panel of the transceiver. This may result in an electric shock. NEVER expose the transceiver to rain, snow or any liquids. 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 (+176F), resulting in per-

manent damage to the transceiver if left there for ex-

tended periods. AVOID placing the transceiver in excessively dusty en-

vironments or in direct sunlight. AVOID placing the transceiver against walls or putting anything on top of the transceiver. This will obstruct heat dissipation. Place unit in a secure place to avoid inadvertent use by children. 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 ex-

hausted. 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 transceiver and microphone as far away as possible from the mag-

netic navigation compass to prevent erroneous indica-

tions. BE CAREFUL! The heatsink will become hot when op-

erating the transceiver continuously for long periods. BE CAREFUL! If a linear amplifier 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 manufacturers microphones have different pin assignments, and connection to the IC-756PROII may damage the transceiver. i Spurious may be received near the following frequencies. These are made in the internal circuit and does not indicate a transceiver malfunction:

(p. 66) 13 3 INSTALLATION AND CONNECTIONS n Unpacking After unpacking, immediately report any damage to the delivering carrier or dealer. Keep the shipping cartons. For a description and a diagram of accessory equip-

ment included with the IC-756PROII, see Supplied ac-

cessories on p. 1 of this manual. n Selecting a location Select a location for the transceiver that allows ade-

quate air circulation, free from extreme heat, cold, or vibrations, and away from TV sets, TV antenna ele-

ments, radios and other electro-magnetic sources. The base of the transceiver has an adjustable stand for desktop use. Set the stand to one of two angles de-

pending on your operating conditions. 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 be-

tween the [GND] terminal and ground as short as pos-

sible. R WARNING: NEVER connect the [GND]

terminal to a gas or electric pipe, since the connec-

tion could cause an explosion or electric shock. n Antenna connection For radio communications, the antenna is of critical im-

portance, along with output power and sensitivity. Se-

lect antenna(s), such as a well-matched 50 antenna, and feedline. 1.5:1 or better of Voltage Standing Wave Ratio (VSWR) is recommended for your desired band. Of course, the transmission line should be a coaxial cable. When using 1 antenna, use the [ANT1] connector. CAUTION: Protect your transceiver from lightning by using a lightning arrestor. PL-259 CONNECTOR INSTALLATION EXAMPLE 30 mm Coupling ring 10 mm (soft solder) 10 mm Soft solder 12 mm solder solder q w e r Slide the coupling ring down. Strip the cable jacket and soft solder. Strip the cable as shown at left. Soft sol-

der the center con-

ductor. Slide the connector body on and solder it. Screw the coupling ring the connector body. onto 30 mm 98 in 10 mm 38 in 12 mm 116 in Antenna SWR Each antenna is tuned for a specified 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-

tor. In this case, an 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-756PROII has an SWR meter to mon-

itor the antenna SWR continuously. 14 INSTALLATION AND CONNECTIONS 3 n Required connections Front panel CW KEY HF/50MHz TRANSCEIVER TIMER POWER TRANSMIT PHONES TUNER MONITOR NB NR i756PRO ELEC-KEY AF RF/SQL BAL NR MIC SPLIT 1.8 1 3.5 2 7 10 21 4 7 GENE 14 24 50 5 8 0 3 6 9 Y Z MW 18 28 F-INP ENT M-CL MP-W MP-R TS XFC LOCK DUAL WATCH CHANGE VFO/

tor, and traditionally refers to an oscillator. The transceivers VFO is somewhat different. The VFO of the IC-756PROII acts like a computers window and can show one frequency and one operating mode. You can call up a desired frequency to the VFO with the keypad, memo pad-read switch (see p. 56) or the memory transfer function (see p. 54). You can also change the frequency with the tuning dial and select the operating mode with the mode switches. During dualwatch or split frequency operation, the sub VFO is functional (non-outline, non-spotted, larger fre-

quency characters). While pushing [XFC] during split frequency operation, you can change the transmit readout frequency with the keypad, memo pad-read switch or the memory transfer function.

(BAND KEY) 21.295 MHz Differences between VFO mode and memory mode VFO MODE VFO shows a frequency and operating mode. If the frequency or operating mode is changed, the VFO automatically memorizes the new frequency or new operating mode. MEMORY MODE (pgs. 5155) 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 operating mode. When a VFO is selected from another band or mem-

ory mode, the frequency and operating mode last used for that VFO appear. When the memory channel is selected from another memory channel or VFO mode, the memorized fre-

quency and operating mode appear.

TRIPLE BAND STACKING REGISTER The triple band stacking register provides 3 memories in one band. 3 sets of a frequency and mode on each band are automatically stored when used. If a band key is pushed once, the frequency and mode last used are called up. When the key is pushed again, another stored frequency and mode are called up. This function is convenient when you operate 3 modes on one band. For example, one register is used for a CW frequency, another for an SSB fre-

quency and the other one for an RTTY frequency.

quency to slightly outside of the IF lter passband to reject interference. This transceiver uses the DSP cir-

cuit for the PBT function. Moving both [TWIN PBT]

controls to the same position shifts the IF.

The LCD shows the passband width and shift fre-

quency graphically.

Push [FILTER] for 1 sec. to enter the lter set mode. Current passband width and shift frequency is dis-

played in the lter set mode screen.

To set the [TWIN PBT] controls to the center posi-

tions, push [PBT CLR] for 1 sec. See the diagram below for the order of selection. USB-D USB LSB LSB-D SSB CW-R CW RTTY RTTY-R CW/RTTY AM-D AM FM FM-D AM/FM Push mode switch for 1 sec. Push mode switch momentarily. The variable range depends on the passband width and mode. The edge of the variable range is half of the passband width, and PBT is adjustable in 25 or 50 Hz steps. These controls function as an IF shift control while in AM mode and when the RTTY lter is turned ON. Only the inner control may function in this case. IF shift is adjustable in 20/40 Hz steps in RTTY (RTTY lter is turned ON) or 150/300/500 Hz steps in AM.

[TWIN PBT] should normally be set to the center posi-

tions (PBT setting is cleared) when there is no interfer-

ence. When PBT is used, the audio tone may be changed. Not available for FM mode. While rotating [TWIN PBT], noise may occur. This comes from the DSP unit and does not indicate an equipment malfunction.

(Pre-amplier 2) The P.AMP 2 is a high gain receive amplier. When the P.AMP 2 is used during times of strong electric fields, distortion sometimes results. In such cases, use the transceiver with the P.AMP 1 or P.AMP OFF setting. The P.AMP 2 is most effective when:

[LOCK] switch n Repeater operation A repeater amplies received signals and retransmits them at a different frequency. When using a repeater, the transmit frequency is shifted from the receive fre-

quency by an offset frequency. A repeater can be ac-

cessed using split frequency operation with the shift frequency set to the repeaters offset frequency. For accessing a repeater which requires a repeater tone, set the repeater tone frequency in set mode as described below. q Set the offset frequencies (HF, 50 MHz) and turn ON the quick split function in set mode (others) in advance.

n Antenna tuner operation The internal automatic antenna tuner matches the transceiver to the connected antenna automatically. Once the tuner matches an antenna, the variable ca-

pacitor 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. TUNER OPERATION

Push the [TUNER] switch to turn the internal an-

tenna tuner ON. The antenna is tuned automati-

cally when the antenna SWR is higher than 1.5:1. When the tuner is ON, the [TUNER] switch lights. MANUAL TUNING During SSB operation at low voice levels, the internal tuner may not be tuned correctly. In such cases, man-

ual tuning is helpful.

Push [TUNER] for 1 sec., to start manual tuning. A side tone is emitted and [TUNER] blinks while tuning. If the tuner cannot reduce the SWR to less than 1.5:1 after 20 sec. of tuning, the [TUNER] switch indicator goes out. AUTOMATIC TUNER START (HF bands only) If you want to deactivate the tuner under conditions of VSWR 1.5:1 or less, use the auto tuner start func-

tion and turn the tuner OFF. This function activates the tuner automatically when the SWR exceeds 1.5:1. This function is turned ON in set mode. (p. 71). RECEIVE AND TRANSMIT 5 CAUTION: NEVER transmit with the tuner ON when no antenna is connected. This will damage the transceiver. Be careful of the antenna selection.

[TUNER] switch Push [TUNER] for 1 sec. PTT TUNER START The tuner is always tuned when the PTT is pushed after the frequency is changed (more than 1% from last-tuned frequency). This function removes the push and hold [TUNER] operation and activates for the rst transmission on a new frequency. This function is turned ON in set mode. (p. 71). NOTES:

If the tuner cannot tune the antenna Check the following and try again:

the [ANT] connector selection. the antenna connection and feedline. the unaltered antenna SWR. (Less than 3:1 for HF bands;

Less than 2.5:1 for 50 MHz band) the transmit power. (8 W for HF bands; 15 W for 50 MHz band) the power source voltage/capacity. If the tuner cannot reduce the SWR to less than 1.5:1 after checking the above, perform the following:

repeat manual tuning several times. tune with a 50 dummy load and re-tune the antenna. turn power OFF and ON. adjust the antenna cable length.

(This is effective for higher frequencies in some cases.) Tuning a narrow bandwidth antenna Some antennas, especially for low bands, have a nar-

row bandwidth. These antennas may not be tuned at the edge of their bandwidth, therefore, tune such an antenna as follows:

Suppose you have an antenna which has an SWR of 1.5:1 at 3.55 MHz and an SWR of 3:1 at 3.8 MHz. q Push [TUNER] to turn the antenna tuner ON. w Select CW mode. e Turn OFF the break-in function. (p. 5) r Push [TRANSMIT] to set to the transmit condition. t Set 3.55 MHz and key down. y Set 3.80 MHz and key down. u Push [TRANSMIT] to return to the receive condition. 49 5 RECEIVE AND TRANSMIT n Optional external tuner operation AH-4/AH-3 HF AUTOMATIC ANTENNA TUNER The AH-4/AH-3 matches the IC-756PROII to a long wire antenna more than 3 m/10 ft long (3.5 MHz and above) or more than 12 m/40 ft long (1.8 MHz and above). See p. 19 for the transceiver and AH-4/AH-3 connection. See the AH-4/AH-3 instruction manual for AH-4/AH-3 in-

stallation and antenna connection details. AH-4/AH-3 setting example:

For mobile operation Optional AH-2b antenna element For outdoor operation Long wire R WARNING: HIGH VOLTAGE!

NEVER touch the antenna element while tuning or transmitting. NEVER operate the AH-4/AH-3 without an antenna wire. The tuner and transceiver will be damaged. NEVER operate the AH-4/AH-3 when it is not grounded. Transmitting before tuning may damage the trans-

ceiver. Note that the AH-4/AH-3 cannot tune when using a 12 l long wire or multiple of the operating fre-

quency. ANTENNA TUNER OF THE IC-PW1 When using an external antenna tuner such as the IC-PW1s tuner, tune with the external antenna tuner, while the internal tuner is turned OFF. After tuning is completed, turn the internal tuner ON. Otherwise, both tuners tune simultaneously and correct tuning may not be obtained. 50 When connecting the AH-4/AH-3, the antenna connector assignments are [ANT2] for the internal tuner and [ANT1] for the AH-4/AH-3. The antenna indicator in the LCD displays ANT1(EXT) when the AH-4/AH-3 is connected and selected. The AH-3 can be used for HF bands only. It can-

not be used for the 50 MHz band. AH-4/AH-3 operation Tuning is required for each frequency. Be sure to re-tune the antenna before transmitting when you change the frequencyeven slightly. q Set the desired frequency in an HF or 50 MHz band for using with the AH-4. Set the desired fre-

quency in an HF band for using with the AH-3. The AH-4/AH-3 will not operate on frequencies outside of ham bands. w Push [TUNER] for 1 sec. The [TUNER] light blinks while tuning.

[TUNER] switch e The [TUNER] light lights constantly when tuning is complete. When the connected wire cannot be tuned, the

[TUNER] light goes out, the AH-4/AH-3 is bypassed and the antenna wire is connected to the antenna con-

nector on the transceiver directly. r To bypass the AH-4/AH-3 manually, push [TUNER]. See the instruction manual included with each an-

tenna tuner for their respective operations. MEMORY OPERATION 6 n Memory channels The transceiver has 101 memory channels. The mem-

ory mode is very useful for quickly changing to often-

used frequencies. All 101 memory channels are tuneable which means the programmed frequency can be tuned temporarily with the tuning dial, etc. in memory mode. MEMORY CHANNEL Regular memory channels Scan edge memory channels MEMORY CHANNEL NUMBER 199 P1, P2 CAPABILITY TRANSFER TO VFO OVER-

6 MEMORY OPERATION n Memo pads The transceiver has a memo pad function to store fre-

quency and operating mode for easy write and recall. The memo pads are separate from memory channels. The default number of memo pads is 5, however, this can be increased to 10 in set mode if desired. (p. 73) Writing frequencies and operating modes into memo pads You can simply write the accessed readout frequency and operating mode by pushing [MP-W]. 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. Each memo pad must have its own unique combi-

nation of frequency and operating mode; memo pads having identical settings cannot be written. MEMO PADS Memo pads are convenient when you want to memo-

rize a frequency and operating mode temporarily, such as when you nd a DX station in a pile-up, or when a desired station is busy for a long time and you want to temporarily search for other stations. Use the transceivers memo pads instead of relying on hastily scribbled notes that are easily misplaced. Displayed frequency and mode USB wq.wii.ww Push MP-W USB qr.qot.pp Newest USB qr.qiw.rp USB wq.pqi.py USB wq.pwr.tw USB wq.wuy.pp Oldest The oldest written frequency and mode are erased. Calling up a frequency from a memo pad You can simply call up the desired frequency and op-

erating mode of a memo pad by pushing [MP-R] sev-

eral times. Both VFO and memory modes can be used. 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 [MP-R], the previously dis-

played frequency and operating mode are automati-

cally stored in a temporary pad. The frequency and operating mode in the temporary pad can be recalled by pushing [MP-R] several times. You may think there are 6 memo pads because 6 different frequencies (5 are in memo pads and 1 is in the tempo-

rary pad) are called up by [MP-R]. If you change the frequency or operating mode called up from a memo pad with the tuning dial, etc., the frequency and operating mode in the tem-

porary pad are erased. MEMO PADS Push MP-R USB qr.qot.pp VFO or MEMORY mode display USB qr.qot.pp Pushing [MP-R] calls up the frequency and operating mode in a memo pad and the temporary pad sequen-

You can operate a scan while operating on a frequency using the dualwatch or split functions. See p. 31 for details. PROGRAMMED SCAN Repeatedly scans between two scan edge frequencies

(scan edge memory channels P1 and P2). F SCAN Repeatedly scans within F span area. Scan edge P1 or P2 Scan edge P2 or P1 F frequency

+F frequency Start frequency Scan Jump Scan Scan Jump This scan operates in VFO mode. This scan operates in both VFO and memory modes. MEMORY SCAN Repeatedly scans all programmed memory channels. SELECT MEMORY SCAN Repeatedly scans all select memory channels.

dard regulations. Please do not use these equipments within European countries. 84 INSTALLATION NOTES For amateur base station installations it is recommended that the forwards clearance in front of the antenna array is calculated relative to the EIRP (Effective Isotropic Radiated Power). The clearance height below the antenna array can be determined in most cases from the RF power at the antenna input terminals. As different exposure limits have been recommended for differ-

ent frequencies, a relative table shows a guideline for installa-

tion considerations. Below 30 MHz, the recommended limits are specied in terms of V/m or A/m elds as they are likely to fall within the near-eld re-

gion. Similarly, the antennae may be physically short in terms of electrical length and that the installation will require some an-

tenna matching device which can create local, high intensity magnetic elds. Analysis of such MF installations is best consid-

ered in association with published guidance notes such as the FCC OET Bulletin 65 Edition 97-01 and its annexes relative to amateur transmitter installations. The EC recommended limits are almost identical to the FCC specied uncontrolled limits and tables exist that show pre-calculated safe distances for different antenna types for different frequency bands. Further information can be found at http://www.arrl.org/. Typical amateur radio installation Exposure distance assumes that the predominant radiation pat-

tern is forwards and that radiation vertically downwards is at unity gain (sidelobe suppression is equal to main lobe gain). This is true of almost every gain antenna today. Exposed persons are assumed to be beneath the antenna array and have a typical height to 1.8 m. The gures assume the worst case emission of constant carrier. For the bands 10 MHz and higher the following power density limits have been recommended:

10 400 MHz 435 MHz 2 W/sq m 2.2 W/sq m ABOUT CE 16 EIRP clearance heights by frequency band Watts 1 10 25 100 1000 102 m 2.1 m 2.8 m 3.4 m 5 m 12 m 70 cm 2 m 2.7 m 3.3 m 4.7 m 11.5 m 23 cm 13cm and above 2 m 2.5 m 2.7 m 3.6 m 7.3 m 2 m 2.3 m 2.5 m 3.2 m 6.3 m Forward clearance, EIRP by frequency band Watts 100 1000 10,000 100,000 102 m 2 m 6.5 m 20 m 65 m 70 cm 2 m 6 m 18 m 60 m 23 cm 13cm and above 1.1 m 3.5 m 11 m 35 m 0.7 m 3 m 7 m 29 m In all cases any possible risk depends on the transmitter being activated for long periods. (actual recommendation limits are specied as an average during 6 minutes) Normally the trans-

mitter is not active for long periods of time. Some radio licenses will require that a timer circuit automatically cuts the transmitter after 12 minutes etc. Similarly some types of transmitter, SSB, CW, AM etc. have a lower average output power and the assessed risk is even lower. Versions of the IC-756PROII which display the CE symbol on the serial number seal, comply with the essential requirements of the European Radio and Telecommunication Terminal Directive 1999/5/EC.
