Resetting the Microcomputer
•
For U.S.A. and Canada
For other countries
If the microcomputer may malfunction (unit cannot be operated,
or shows an erroneous display) if the power cord is unplugged
while the power is ON, or due to some other external factor. If
this happens, execute the following procedure to reset the
microcomputer and return the unit to its normal operating
condition.
Please note that resetting the microcomputer will clear the contents
of the memory and returns the unit to the state it was in when it left
the factory.
Unplug the power cord from the wall outlet, then plug it back in
while holding down the POWER key.
With the power cord plugged in, turn the POWER key OFF. Then,
while holding down the ON/STANDBY key, press POWER.

CIRCUIT DESCRIPTION
This unit works backup by microprocessor if power is off. The
microprocessor carries out the power-off-checking by 1ms. It
sets up the initialized data if the backup data is destroyed.
Also plug in and out the power cord from the outlet with
pressing the power switch for initialization.

CIRCUIT DESCRIPTION
4. Test mode specification
1. How to set up the test mode.
Test mode How to set up.
Normal test mode BAND key+AC-ON
2. How to cancel the test mode.
• TEST MODE is initialized by cutting off the power supply.
• Power off is initialization can't be set up. Power off cancels only the test mode.
3. How to set up the initialization of the set.
An initialization movement is done, and FL indication is erased when AC is turned on with pushing POWER key of set.
4. A key movement during the all LCDs lighting.
4-1 A setup of Rf receiving frequency one touch. (only VR-410)

4-3 CHANNEL SPACE SW(50kHz/100kHz) indication(only M/C/Y/I/V TYPE)
When SPEAKERS A key is pushed, it is checked, and the condition of CHANNEL SPACE SW of the TUNER
circuit board is indicated with EON of the FL indication and TI.VOL.
(It is made to indication of CHANNEL SPACE SW at that time at the time of POWER supply on in FL)
5. TEST TONE easy function
The key movement when selector is DVD.
6. A release of TEST MODE
The Key movement when selector is DVD.
