Operation to reset
÷ Please note that resetting the microprocessor clears the
contents stored in, it returns the microprocessor to the condition when it left the factory.
1 In Power ON condition, keep the 7 (Stop) key and the ¡
(Search) 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 display. (When nothing is done, the display of this
information continues.)
Example: 72. 14.02:05
3 Press the POWER ON/OFF switch to go to Power OFF.
4 When Power ON is performed with the
POWER ON/OFF
switch, the settings become the default factory settings.
The microprocessor may fall into malfunction (impossibility 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.
The marking of products using lasers
(For countries other than U.S.A., U.S.-Military and Canada)
The marking this product has been classified as Class 1. It
means that there is no danger of hazardous radiation outside
the product.
