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 an AC outlet or

to a DC power supply that outputs more than the

specified voltage. This will ruin the transceiver.

DO NOT expose the transceiver to rain, snow or

liquids.

DO NOT reverse the polarity of the DC power cable

when directly connecting to the transceiver.

DO NOT apply an RF signal of more than 20 dBm

(100 mW) to the antenna connector. This could

damage the transceiver.

ORDERING PARTS

Be sure to include the following four points when

ordering replacement parts:

1. 10-digit Icom part number

2. Component name

3. Equipment model name and unit name

4. Quantity required

1130018740 RX8130CE IP501M MAIN-A UNIT 5 pieces
