This service manual describes the latest service information 
for the 

IC-F80DT/DS and IC-F80T/S 

UHF TRANSCEIVERS

 

at the time of publication.

DANGER

NEVER

 connect the transceiver to an AC outlet or to a DC 

power supply that uses more than 7.2 V. Such a connection 
could cause a fire or electric hazard.

DO NOT 

expose the transceiver to rain, snow or any liquids.

DO NOT

 reverse the polarities of the power supply when 

connecting the transceiver.

DO NOT

 apply an RF signal of more than 20 dBm (100 mW)

to the antenna connector. This could damage the trans-
ceiver's front end.

Be sure to include the following four points when ordering 
replacement parts:

1.  10-digit order numbers
2.  Component part number and name
3.  Equipment model name and unit name

REPAIR  NOTES

1.  Make sure a problem is internal before disassembling the transceiver.
2. 

DO NOT

 open the transceiver until the transceiver is disconnected from its power source.

3. 

DO NOT

 force any of the variable components. Turn them slowly and smoothly.

4. 

DO NOT

 short any circuits or electronic parts. An insulated turning tool 

MUST

 be used for all adjustments.

5. 

DO NOT

 keep power ON for a long time when the transceiver is defective.

6. 

DO NOT

 transmit power into a signal generator or a sweep generator.

7. 

ALWAYS

 connect a 30 dB to 40 dB attenuator between the transceiver and a deviation meter or spectrum analyzer 

when using such test equipment.

8. 

READ

 the instructions of test equipment thoroughly before connecting equipment to the transceiver.

To upgrade quality, all electrical or mechanical parts and internal 
circuits are subject to change without notice or obligation.
