SERVICE PROCEDURES

TX-NR900/E

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

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 the STANDBY ON button to turn on the unit.

2.Press and hold down the VIDEO 1 button, then press the
STANDBY/ON button.

3.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.

4.Unplug the power supply cord.

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.

4. Memory Preservation

This unit does not require memory preservation batteries. A
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 char ge 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.

5.Setting the voltage selector
(Worldwide models only)

Worldwide models are equipped with a voltage selector so
that you
supplies. Be

the power supply in

can set your TX-NR900 to conform with local power

sure to set this switch to match the voltage of

your area before plugging in the unit.
Determine the proper voltage for your area: 220-230 V or
120 V. If

insert a screwdriver

the preset voltage is not correct for your area,

into the groove in the switch and slide

the switch all the way to the top (120 V) or bottom

(220-230 V), whichever is appropriate.

(Worldwide model only)

This sub-menu only appears on the worldwide model. The
setting in this sub-menu determines the increment amount
or decrement amount when adjusting the AM tuner frequency.
The initial setting is 9 kHz, and this needs only to be changed
if you are using the TX-NR900 in a 10-kHz region.
