use is necessary.)
Operation to reset
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.
0 Please note that resetting the microprocessor clears the
contents stored in, It returns the microprocessor to the con
dition when it left the factory.
0 In Power ON condition,keepthel (Stop) keyand the >>
(Search) key pressed at the same time.
9 When both keys are pressed, the region code of the
unit, the software version, etc. will be displayed on
the display. (When nothing is done, the display of this
information continues.)
Example: 72. 14.0205
9 Press the POWER ONIOFF switch to go to Power OFF.
0 When Power ON is performed with the POWER ONIOFF
switch, the settings become the default factory settings.
