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

4.Setting the Voltage selector (Worldwide models
only)

W

orldwide models are equipped with a voltage selector to conform with
local power supplies. Be sure to set this switch to match the voltage of
the power supply in your area before plugging in the unit.

1.

Determine the proper voltage for your area: 220-240 V or
120 V.

2.

If the preset voltage is not correct for your area, insert a screw­driver into the groove in the switch. Slide the switch all the way
to the right (120 V) or to the left (220-240 V), whichever is
appropriate.

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 VIDEO-1 button, then press the
STANDBY 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.

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.).

5. Changing the AM band step

With the exception of the worldwide models, a tuning step selector
switch is not provided. When you change the band step, change
the parts as shown below.
