VHF TRANSCEIVER
This service manual describes the latest service information
for the IC-F14/S IC-F15/S IC-F16/S IC-F3018 VHF
TRANSCEIVER at the time of publication.
NEVER connect the transceiver to an AC outlet or to a DC
power supply that uses more than specifed. This will ruin
the transceiver.
DO NOT expose the transceiver to rain, snow or any liquids.
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.
To upgrade quality, any electrical or mechanical parts and
internal circuits are subject to change without notice or
obligation.
Be sure to include the following four points when ordering
replacement parts:
1. 10-digit Icom parts numbers
2. Component name
3. Equipment model name and unit name
4. Quantity required

1110003491 S.IC TA31136FNG IC-F14 MAIN UNIT 5 pieces
8820001210 Screw 2438 screw IC-F14 Top cover 10 pieces
Addresses are provided on the inside back cover for your
convenience.

Kingdom, Germany, France, Spain, Russia and/or other countries.
ORDERING PARTS
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 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 Standard 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 throughly
before connecting a test equipment to the transceiver.
