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.
4. Memory Preservation
This unit does not require memory preservation batteries. A
built-in memory power 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 preserv ation 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 fe w 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
can set your TX-NR801 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
the preset voltage is not correct for your area,
into the groove in the switch and slide
(220-230 V), whichever is appropriate.
the power supply in
120 V. If
insert a screwdriver
the switch all the way to the top (120 V) or bottom
3. Safety-check out
(U.S.A. model only)
After correcting the original service problem, perform the
following safety check before releasing the set to the customer.
Leakage Current Check
Measure leakage current to a known earth ground(water pipe,
conduit, etc.) by connecting a leakage current tester between
the earth ground and exposed metal parts of the appliance
(input/output terminals, screwheads,metal overlays, etc.).
Plug the power supply cord directly into a 120V AC 60 Hz outlet
and turn Standby switch on. Any current meausred must not
exceed 0.5mA.
