INTRODUCTION
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.
ORDERING PARTS
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
4. Quantity required

1130010100 S.IC LMX2352TM IC-F80DS Main unit 5 pieces
8810010121 Screw PH B0 M28 SUS SSBC IC-F80DS Chassis 10 pieces
Addresses are provided on the inside back cover for your
convenience.
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.
