Setting the reception area

1. While pressing the CH3 and CH4 button,press the UP

button to change the AM Receiving area from 9 kHz step

to 10 kHz step.

NOTE

There are two models with a different production place.

China production : RN-9437G-A

Malaysia production: RN-9437G-B

All the same parts are used and assemble these mod-

els.

We cannot supply PWB with component parts in prin-

ciple. When a circuit on PWB has failure, please repair it

by component parts base. Parts which are not mentioned

in service manual are not supplied.

Specifications and design are subject to change without

notice for further improvement.

COMPONENTS

RN-9437G-A,B

Main unit

---------

To engineers in charge of repair or

inspection of our products.

Before repair or inspection, make sure to follow the

instructions so that customers and Engineers in charge

of repair or inspection can avoid suffering any risk or

injury.

1. Use specified parts.

The system uses parts with special safety features against fire

and voltage. Use only parts with equivalent characteristics

when replacing them.

The use of unspecified parts shall be regarded as remodeling

for which we shall not be liable. The onus of product liability

(PL) shall not be our responsibility in cases where an accident

or failure is as a result of unspecified parts being used.

2. Place the parts and wiring back in their original positions after

replacement or re-wiring.

For proper circuit construction, use of insulation tubes, bond-

ing, gaps to PWB, etc, is involved. The wiring connection and

routing to the PWB are specially planned using clamps to keep

away from heated and high voltage parts. Ensure that they are

placed back in their original positions after repair or inspec-

tion.
