The unit will now have the correct DATA for the new MEMORY IC.
ADDRESS is now selected and should "blink". Using the VOL. +/- button on the remote, step through the ADDRESS until
required ADDRESS to be changed is reached.
Press ENTER to select DATA. When DATA is selected, it will "blink".
Again, step through the DATA using VOL. +/- button until required DATA value has been selected.
Pressing ENTER will take you back to ADDRESS for further selection if necessary.
Repeat steps 3 to 6 until all data has been checked.
When satisfied correct DATA has been entered, turn POWER off (return to STANDBY MODE) to finish DATA input.
After the data input, set to the initializing of shipping.
Turn POWER on.
While holding down VOLUME button on front cabinet, press key 1 on remote control for more than 2 seconds.
After the finishing of the initializing of shipping, the unit will turn off automatically.

BEFORE MAKING ELECTRICAL
ADJUSTMENTS
Use an isolation transformer when performing any
service on this chassis.
Before removing the anode cap, discharge electricity
because it contains high voltage.
When removing a PCB or related component, after
unfastening or changing a wire, be sure to put the wire
back in its original position.
When you exchange IC and Transistor for a heat sink,
apply the silicon grease (YG6260M) on the contact
section of the heat sink. Befor applying new silicon
grease, remove all the old silicon grease. (Old grease
may cause damages to the IC and Transistor.)
Read and perform these adjustments when repairing the
circuits or replacing electrical parts or PCB assemblies.
