period of a fe w weeks after the last time the unit has been
unplugged. This period is shorter when the unit is e
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
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.Turn POWER to on.
2.Press and hold down the PRESET MEMORY button, then press the
STANDBY button.
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.Disconnect 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.
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.
