VHF TRANSCEIVER
This service manual describes the latest technical
information for the IC-V80/IC-V80E VHF TRANSCEIVER, at
the time of publication.
NEVER connect the transceiver to an AC outlet or to a DC
power supply that uses more than specified. This will ruin
the transceiver.
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 transceiver’s
front-end.
To upgrade quality, any electrical or mechanical parts
and internal circuits are subject to change without notice
or obligation.

ORDERING PARTS
1. Make sure that the 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 tuning 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 Standard Signal
Generator or a Sweep Generator.
7. ALWAYS connect a 50 dB to 60 dB attenuator between
the transceiver and a Deviation Meter or Spectrum
Analyzer when using such test equipment.
8. READ the instructions of test equipment throughly
before connecting a test equipment to the transceiver.
