SERVICE PROCEDURES

1. Replacing the fuse

This symbol located near the fuses indicates that the

fuse used is fast operating type. For continued protection against

fire hazard, replace with same type fuse.For fuse rating refer to

the marking adjacent to the symbol.

Ce symbole indique que le fusible utlise est a rapide.

Pour une protection permanente, n'untiliser que fusibles de

meme type. Ce darnier est la qu le present symbol est

appse.

CIRCUIT NO. PART NO. DESCRIPTION

F901 252163 4A-UL/T-237,Fuse

2.To initialize the unit

This device employs a microprocessor to perform various

functions and operations.If interference generated by an external

power supply, radio wave, or other electrical source results in

accident which causes the specified operations and functions to

operate abnormally.

To perform a result, please follow the procedure below.

1.Press and hold down the TAPE 1 button, then press the

DIRECT TUNING button.

2.After "CLEAR" is displayed, the preset memory stored in the memory,

are initialized and will return to the factory setting.

3. Safety-check out

(Only U.S.A. model)

After correcting the original service problem, perform the

following safety check before releasing the set to the customer.

Connect the insulating-resistance tester between the plug of power

supply cord and screw on the back panel.

Specifications: 3.3Mohmr10% at 500V.

4. Memory Preservation

This unit does not require memory preservation batteries. A

built-in memory power back-up system preserv es the contents

of the memory during power failures and even when the unit is

unplugged. The unit must be plugged in order to charge the

back-up system.

The memory preservation period after the unit has been

unplugged varies depending on climate and placement of the

unit. On the average, memory contents are protected over a

period of a few weeks after the last time the unit has been

unplugged. This period is shorter when the unit is exposed to a

highly humid climate.
