Operation to reset
÷ Please note that resetting the microprocessor clears the
contents stored in, it returns the microprocessor to the con-
dition when it left the factory.
1 In Power ON condition, keep the DISC 3 key and the 4
(Skip) key pressed at the same time.
2 When both keys are pressed, the region code of the unit,
the software version, etc. will be displayed on the dis-
play. (When nothing is done, the display of this informa-
tion continues.) Example: 72. 14.02:05
3 Press the DISC 4 key and the 4

4 key at the same time.
"BYE" will be shown on the display.
4 Press the POWER ON/OFF switch to go to Power OFF.
5 When Power ON is performed with the POWER ON/OFF
switch, the settings become the default factory settings.
The microprocessor may fall into malfunction (impos-
sibility to operate erroneous display, etc.) when the
power cord is unplugged while power is ON or due to
an external factor. In this case, execute the following
procedure to reset the microprocessor and return it to
normal condition.
