To upgrade quality, any electrical or mechanical parts and
internal circuits are subject to change without notice or
obligation.
SERVICE CAUTION
NEVER connect the receiver to a DC power supply
that uses more than the specified voltage. This will
ruin the receiver.
DO NOT expose the receiver to rain, snow or liquids.
DO NOT reverse the polarities of the power supply
when connecting the receiver.
ORDERING PARTS
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
<ORDER EXAMPLE>
1110009630 NJG1108HA8-TE1 IC-R30 MAIN UNIT 5 pieces

Addresses are provided on the inside back cover for
your convenience.
REPAIR NOTES
1. Make sure that the problem is internal before
disassembling the receiver.
2. DO NOT open the receiver until you have
disconnected it 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
receiver is defective.
6. READ the instructions of the test equipment
thoroughly before connecting it to the receiver.

1. REMOVING THE FRONT PANEL
1) Remove the 6 screws from the rear panel.
2. REMOVING THE LOGIC/-1 UNIT
1) Unsolder 3 points at the encoder and a point at the
shield plate.
2) Separate the front panel from the rear panel,and then
disconnect the flat cable from the LOGIC/-1 UNIT and
the speaker cable from the MAIN UNIT.
BE CAREFUL about the flat and speaker cable when
separating the front panel from the rear panel.
2) Remove the 6 screws from the LOGIC/-1 UNIT, and then
remove the LCD holder and the LCD sheet from the
LOGIC/-1 UNIT.
BE CAREFUL the LCD sheet has conductive and
insulating surfaces. When installing the LCD sheet, make
sure that the conductive surface contacts the LCD holder.
