PMR446 TRANSCEIVER

This service manual describes the latest technical informa-

tion for the IC-F29SR PMR446 TRANSCEIVERS, at the time of pub-

lication.

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

power supply that uses more than the speciﬁ ed voltage. This

will ruin the transceiver.

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

DO NOT reverse the polarities of the power supply when con-

necting 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 part number

2. Component name

3. Equipment model name and unit name

4. Quantity required

1110003491 S.IC TA31136FNG IC-F29SR MAIN UNIT 5 pieces

8820001210 Screw 2438 screw IC-F29SR Top cover 10 pieces

Addresses are provided on the inside back cover for your

convenience.

ORDERING PARTS

1. Make sure that the problem is internal before dis-assem-

bling the transceiver.

2. DO NOT open the transceiver until the transceiver is dis-

connected 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 trans-

ceiver is defective.

6. DO NOT transmit power into a Standard Signal Generator

or a Sweep Generator, otherwise the RF power may dam-

age them.

7. ALWAYS connect a 30 dB to 40 dB attenuator between the

transceiver and a Deviation Meter or Spectrum Analyzer,

when using such test equipment.

8. READ the instructions of the test equipment thoroughly

before connecting it to the transceiver.
