INTRODUCTION
This service manual describes the latest service information for
the IC-F30GT/GS and IC-F31GT/GS VHF TRANSCEIVER at
the time of publication.
To upgrade quality, all electrical or mechanical parts and inter-
nal circuits are subject to change without notice or obligation.
DANGER
NEVER connect the transceiver to an AC outlet or to a DC
power supply that uses more than 10 V. This will ruin the
transceiver.
DO NOT expose the transceiver to rain, snow or any liq-
DO NOT reverse the polarities of the power supply when
connecting the transceiver.
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.
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

1110001810 S.IC TA7368F IC-F30GT MAIN UNIT 1 piece
8930053170 2337 Key board IC-F31GS CHASSIS 5 pieces
Addresses are provided on the inside back cover for your
convenience.
REPAIR NOTES
1. Make sure a 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 tuning 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 40 dB or 50 dB attenuator between the transceiver and a deviation meter or spectrum analyser when
using such test equipment.
8. READ the instructions of test equipment thoroughly before connecting equipment to the transceiver.
INTRINSICALLY SAFE QUALIFICATION
When servicing intrinsically safe versions of the IC-F30GT/GS
and IC-F31GT/GS the following conditions must be met.
Failing to satisfy any of these conditions will invalidate the
INTRINSICALLY SAFE certification.
1. Servicing the transcever should only be undertaken by
suitably qualified personnel in a non-hazardous area.
Never attempt to remove the case in a hazardous area.
2. ONLY the approved battery, ICOM’s BP-210FM may be
used.
3. USE ONLY safety critical components as specified in the
parts list (SECTION 6), should replacement of any item
be necessary.
