To upgrade quality, any electrical or mechanical parts and
internal circuits are subject to change without notice or
obligation.
SERVICE CAUTION
NEVER connect the transceiver to a DC power supply
that uses more than the specified voltage. This will
ruin the transceiver.
DO NOT reverse the polarities of the power supply
when directly applying power to the transceiver/circuit.
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.

Be sure to include the following four points when
ordering replacement parts:
1. 10-digit Icom part number

REPAIR NOTES
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 short any circuits or electronic parts.
4. DO NOT keep power ON for a long time when the
transceiver is defective.
5. NEVER directly transmit power into any test
equipment such as Standard Signal Generator or
a Sweep Generator, otherwise the RF power may
damage them.
6. ALWAYS connect a 30 dB to 40 dB attenuator
between the transceiver and such test equipment.
7. READ the instruction manual of the test equipment
thoroughly before connecting it to the transceiver.
