SERVICE PROCEDURES

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
appse.

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.

5A-T/UL-ST2 or
5A-UL/T-237

DTM-5.3

1.Press and hold down the DVD button, then press the
Speakers A button.

2.After "CLEAR" is displayed, the preset memory and each
mode stored in the memory, such as surround, are
initialized and will return to the factory setting.
Unplug the power supply cord from outlet.

3. Safety-check out

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.

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 e v en when the unit is
unplugged. The unit must be plugged in order to char ge the
back-up system.
The memory preservation period after the unit has been
unplugged v aries depending on climate and placement of the
unit. On the average, memory contents are protected over a
period of a fe w weeks after the last time the unit has been
unplugged. This period is shorter when the unit is e xposed to a
highly humid climate.
