1、SERVICE MANUAL VHF/UHF ALL MODE TRANSCEIVER |9700 S-15513XZ-C1 March 2019 . INTRODUCTION This service manual describes the latest technical information for the IC-9700 VHF/UHF ALL MODE TRANSCEIVER at the time of publication. MODELVERSION VERSION NUMBER IC-9700 USA#12 EUR#13 ITA#15 TPE#17 KOR#18 EXP#
2、19 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 N
3、OT 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 transceivers front-end. ORDERING PARTS Be sure to
4、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.

5、e inside back cover for your convenience. 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. An insulated tuning too
6、l MUST be used for all adjustments. 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 50 dB to 60 dB a
7、ttenuator between the transceiver and such test equipment. 7. READ the instructions of the test equipment thoroughly before connecting it to the transceiver.
