■Frequency calibration (approximate)

A very accurate frequency counter is required to cali-

brate the frequency of the transceiver. However, a

rough check may be performed by receiving radio sta-

tion WWVH, or other standard frequency signals.

CAUTION: The IC-7800 has been thoroughly ad-

justed and checked at the factory before being

shipped. You should not calibrate frequencies, ex-

cept for special reasons.

qPush [SSB] to select USB mode.

wPush [PBT CLEAR] for 1 sec. to clear the PBT set-

ting and make sure that the RIT/∂TX function is not

activated.

eSet the frequency to the standard frequency station

minus 1 kHz.

• When receiving WWVH (15.00000 MHz) as a standard

frequency, set the operating frequency for

14.99900 MHz.

• Other standard frequency can also be used.

rPush [EXIT/SET] several times to close a multi-

function screen, if necessary.

■Opening the transceiver’s case

Follow the case opening procedures shown here when

you want to replace the clock backup battery or cir-

cuitry fuse,

CAUTION!: DISCONNECT the AC power cable

from the transceiver before performing any work on

the transceiver. Otherwise, there is danger of elec-

tric shock and/or equipment damage.

CAUTION!: The transceiver weighs approx. 25 kg

(55 lb). 2 peoples should be present to lift up or turn

over the transceiver.

qRemove the 8 screws from the top of the trans-

ceiver and the 6 screws from the sides, then lift up

the top cover.

wTurn the transceiver upside down.

CAUTION: NEVER HOLD THE MAIN DIAL OR

ANY OTHER KNOBS when the transceiver is

upside down. This may damage the transceiver.

eRemove 7 screws from the bottom, and the 6

screws from the sides, then lift up the bottom cover.

■Clock backup battery replacement

The IC-7800 has a lithium backup battery (CR2032) in-

side for clock and timer functions. The usual life of the

backup battery is approximately 2 years.

When the backup battery exhausted, the transceiver

transmits and receives normally but cannot retain the

current time.

WARNING: DISCONNECT the AC power cable

from the AC outlet before removing the transceiver’s

cover.

qRemove the top cover as shown above.

wReplace the clock backup battery, located on the

front panel as illustrated at left.

• Make sure the battery polarity is correct.

eReturn the top cover to the original position.

rSet the date and time in time set mode. (p. 11-2)

13 MAINTENANCE

■Fuse replacement

When no external DC output is available from [EXT

DC] and ACC connectors, the internal fuse may be

damaged. Replace the fuse in this case.

WARNING: DISCONNECT the AC power cable

from the AC outlet before removing the transceiver’s

cover.

qRemove the bottom cover as shown left.

wReplace the damaged fuse with new, rated one

(FGB 2 A) as shown at left.

eReturn the bottom cover to the original position.

■Resetting the CPU

qTurn the main power switch on the rear panel ON.

• Make sure the transceiver power is still OFF.

wWhile pushing and holding [F-INP•ENT] and [MW],

push [POWER] to turn power ON.

• The internal CPU is reset.

• The CPU start up and it takes approx. 5 sec.

• The transceiver displays its initial VFO frequencies

when resetting is complete.

eCorrect the set mode settings after resetting, if de-

sired.

NOTE: Resetting CLEARS all programmed con-

tents in memory channels and returns programmed

values in set mode to default values.

■About protection indications

The IC-7800 has a 2-step protection function to protect

the power amplifiers as follow.

The protector detects the power amplifier temperature

and activates when the temperature becomes ex-

tremely high.

• Power down transmission

Reduces the transmit output power to 100 W.

“LMT” appears beside the transmit indicator during

transmit.

• Transmission inhibit

Deactivate the transmitter.

The transmit indicator is displayed in gray during

transmit.

When the protector is activated, wait until the power

amplifier cools down using the transceiver stand-by

condition.

NOTE: DO NOT turn the transceiver power OFF.

The internal cooling fan does not function, so it will

take longer to cool down.

The power amplifier temperature can be confirmed in

multi-function meter, TEMP gauge.

Check the temperature

CT-17 CI-V LEVEL CONVERTER to a PC equipped with an

RS-232C port. The Icom Communications Interface-V

(CI-V) controls the following functions of the trans-

ceiver.

Up to 4 Icom CI-V transceivers or transceivers can be

connected to a PC equipped with an RS-232C port.
