Operation to reset
The microcomputer may fall into malfunction (impossibil-
ity to operate, erroneous display, etc.) when the power
cord is unplugged while unit is ON or due to an external
factor. In this case, execute the following procedure to
reset the microcomputer and return it to normal condi-
tion.
Unplug the power cord from the power outlet, then while
holding the POWER or key depressed, plug the power
cord again.
÷Please note that resetting the microcomputer clears
the contents stored in and it returns to condition
when it left the factory.
or
After resetting the microcomputer, the display will show
as follow:
The marking of products using lasers (For countries other than U.S.A., U.S.-Military and Canada)

CIRCUIT DESCRIPTION
* The oscillation diagnosis (existence of oscillation and measurement of period) of a sub clock is performed
before the test mode is entered. If the diagnosis result is OK, the system enters the test mode.
If the diagnosis result is NG, the oscillation of the sub clock is diagnosed again. If the result is OK, the system
enters the test mode. If the diagnosis result is continuously NG 5 times, the system stops with "ERR1"and
"ERR2"displayed.
