MANUAL

INTRODUCTION

DANGER

This service manual describes the latest service information

for the IC-7000 HF/VHF/UHF ALL MODE TRANSCEIVER

at the time of publication.

NEVER connect the transceiver to an AC outlet or to a DC

power supply that uses more than 16 V. Such a connection

could cause a fire or electric hazard.

VER.NO.

VERSION

SYMBOL

DO NOT expose the transceiver to rain, snow or any liquids.

EXP

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.

To upgrade quality, all electrical or mechanical parts and internal

circuits are subject to change without notice or obligation.

ORDERING PARTS

REPAIR NOTES

Be sure to include the following four points when ordering

replacement parts:

1. Make sure 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 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 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 thoroughly

before connecting equipment to the transceiver.
