INTRODUCTION
This service manual describes the latest service informa-
tion for the IC-FR3000/IC-FR3100 VHF FM REPEATER.
To upgrade quality, all electrical or mechanical parts and
internal circuits are subject to change without notice or
obligation.
DANGER
USE ONLY the specified AC voltage described on the
AC power socket. Other voltages may causes repeater
damage or personal injury.
DO NOT expose the repeater to rain, snow or any liquids.
DO NOT reverse the polarities of the power supply when
connecting the repeater.
DO NOT apply an RF signal of more than 20 dBm (100
mW) to the antenna connector. This could damage the
repeater’s front end.
ORDERING PARTS
Be sure to include the following four points when ordering
replacement parts:
1. 10-digit order numbers
2. Component part number and name
3. Equipment model name and unit name
4. Quantity required

REPAIR NOTES
Make sure a problem is internal before disassembling
the repeater.
DO NOT open the repeater until the repeater is discon-
nected from its power source.
DO NOT force any of the variable components. Turn
them slowly and smoothly.
DO NOT short any circuits or electronic parts. An insu-
lated tuning tool MUST be used for all adjustments.
DO NOT keep power ON for a long time when the re-
peater is defective.
DO NOT transmit power into a signal generator or a
sweep generator.
ALWAYS connect a 40 dB or 50 dB attenuator be-
tween the repeater and a deviation meter or spectrum
analyser when using such test equipment.
READ the instructions of test equipment thoroughly
before connecting equipment to the repeater.
