4. Memory Preservation

This unit does not require memory preservation batteries.

built-in memory po wer back-up system preserves 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.

2. To initialize the unit

This device employs a microprocessor to perform various

functions and operations. If interference generated by an external

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: 3.3Mohm+/-10% at 500V.

1. Replacing the fuses

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
