FCC ID: K6620801X50 Scanning Receiver

Optional Accessories FC-40 External Automatic Antenna Tuner (for Wire Antenna) The FC-40 makes use of the control circuitry built into the transceiver, which allows the operator to control and monitor automatic operation of the FC-40, which mounts near the antenna feedpoint. The FC-40 uses specially selected, thermally stable components, and is housed in a waterproof case to withstand severe environmental conditions with high reliability. A carefully-chosen combination of solid-state switching components and high-speed relays allows the FC-

40 to match a wide variety of antennas to within a 2:1 SWR on any amateur band frequency (160 through 6 meters), typically in less than eight seconds. Transmitter power required for matching may be as little as 4 - 60 Watts, and matching settings are automatically stored in memory for instant recall when the same frequency range is selected later. Please see the FC-40 Operating Manual for detailed information. Depending on the installation and location of some antennas, it may not be possible to tune to a low SWR. Interconnections to FT-710 After mounting the FC-40, connect the cables from the FC-40 to the ANT and TUNER jacks on the rear panel of the FT-710 Transceiver. Turn OFF the external power supply switch and the FT-710 power supply switch first before connecting the ca-

bles. Antenna Cable (supplied with FC-40) Antennna Terminal Antennna GND Terminal TUNER Install the supplied ferrite core as close to the connector as possible. Control Cable (supplied with FC-40) Wrap the ends of the waterproof cap with the supplied sealing tape to protect against moisture ingress. 51 Setup the transceiver The optional FC-40 Automatic Antenna Tuner pro-

vides automatic tuning of a coaxial line to present nominal 50-ohm impedance to the FT-710s ANT jack. Before tuning can begin, the FT-710 must be con-

figured to recognize that the FC-40 is being used. Configuration is done using the Setting Menu Mode:

1. Press the [FUNC] knob. 2. Select [OPERATION SETTING] [GENER-

AL] [TUNER TYPE SELECT]. 3. Rotate the [FUNC] knob, or touch < or >

on either side of the value to select EXT. 4. Press the [FUNC] knob to save the new set-

ting. 5. Touch [BACK] several times to return to nor-

mal operation. Tuning Operation 1. Press the [TUNE] key. A TUNE icon will appear in the display; and the tuner function is activated. 2. Press and hold the [TUNE] key to begin auto-

matic tuning. The transmitter will be engaged, and the TUNER icon will blink while tuning is in progress. When the optimum tuning point has been reached, the transceiver will return to re-

ceive, and the TUNER icon will again glow steadily (instead of blinking). Be sure to connect a good earth ground to the GND terminal of the FC-40. The carrier signal transmits continuously while tuning is in progress. Please monitor the operat-

ing frequency before beginning the tuning pro-

cess. Be sure you are not interfering with others who may already be using the frequency. It is normal to hear the sound of the relays while tuning is in progress. If the impedance cannot be matched by the FC-

40 better than 2:1, and the HI-SWR icon blinks, the microprocessor will not retain the tuning data for that frequency, as the FC-40 presumes that you will want to adjust or repair the antenna sys-

tem to correct the high SWR condition. 52 FH-2 Remote Control Switches With the optional remote-control keypad FH-2 voice messages may be recorded and transmitted (Voice Memory). The FH-2 is also the control of the Contest Memory Keyer during CW operation. SSB / AM / FM modes have five voice memory channels (90 seconds each) for storage and playback, of voice recordings. The CW Memory Keyer has 5 channels each for the MESSAGE Memory and the TEXT Memory. LOCK Switch The FH-2 key keys may be locked by setting this switch to ON. MEM Key Press this key to store either a Voice Memory, or a Contest Keyer Memory. DEC Key When utilizing the sequential contest number capability of the Contest Keyer, press this key to decrement (decrease) the current Contest Number by one digit (i.e. to back up from #198 to #197, etc.).

*No function is assigned to the [P/B] key. Voice Memory: 5 Memory Channels for the Memory Keyer In the case of Voice Memory, up to 90 seconds of audio may be stored on each channel. MESSAGE Memory and TEXT Memory are available for the Contest Memory Keyer. Each MESSAGE Memory channel is capable of retaining a 50-character CW message using the PARIS standard for characters and word length. Each TEXT Memory channel is capable of retain-

ing a maximum of 50 characters. Cursor Keys When programming the Contest Memory Keyer, these keys are used to move the cursor and select the text characters. The cursor may be moved in 4 different directions

(up/down/right/left). NOTE: Usually, these keys are used for changing the VFO frequency. Press the [p]/[q] keys to change the frequency in the same increments as the microphone [UP]/[DWN] switches. Press the

[t]/[u] keys to change the frequency by 100 kHz steps. 53 Resetting the Microprocessor Memory channels, setting menus, and various settings can be initialized and returned to their factory defaults. RESET DONE 1. Display the reset item selection screen. Press the [FUNC] knob touch [EXTENSION SETTING] touch [RESET]

2. Touch DONE of the item you want to reset (see below). Or Select an item with the [FUNC] knob and press the [FUNC] knob. A confirmation screen for reset execution is displayed. MEMORY CLEAR (Memory Reset) Only the contents of the memory channel are initialized (factory default). All stored information will be erased, but channel M-01 will return to the initial setting of 7.000.000 MHz, LSB. MENU CLEAR (Setting Menu Reset) Only the contents of the setting menu are returned to their default values (factory default). ALL RESET (All Reset) Initializes all settings of this unit, including various settings, memories, and setting menus, and re-

stores the factory settings. 3. Touch [OK] or select [OK] with the [FUNC] knob and press the [FUNC] knob to execute the reset. To cancel the reset, touch [CANCEL] or select [CANCEL] with the [FUNC] knob and press the [FUNC]

knob. 4. The power is turned OFF once and then turned ON automatically. The reset is complete. 54 General Tx Frequency Range:

The scanner receiver equipment meets the requirements of the FCC Rules, 15.121(a) and (b). Compliance is achieved through the following methods:

The scanner receiver in this equipment is incapable of tuning, or readily being altered, by the User to operate within the frequency bands allocated to the Domestic Public Cellular Telecommunications Service in Part 22. Blocking of the cellular frequencies is implemented in the firmware of the units main control central processing unit (CPU). Coverage of 824 - 849 MHz and 869 - 894 MHz is completely blocked, since it is done in the microprocessor, and cannot be re-enabled by any user-accessible procedure, including diode, resistor, or jumper changes, nor by connection of any external device such as a personal computer, nor by installation of any special enabling semiconductor device. The scanning receiver is designed so that the tuning, control and filtering circuitry is inaccessible. The scanning receiver is reject any signals from the Cellular Radiotelephone Service frequency bands that are 38 dB or lower based upon a 12 dB SINAD measurement. Sincerely, YAESU MUSEN CO., LTD.
