9.3 Battery exchange
There is a real time clock IC built-in whose power is supplied by a battery when outside power
supply is turned off. When the battery comes to its life, the clock IC won't renew the time when
power supply of WOP is turned off.
The clock date stored in the IC will be reset to a default value January 1, 2009 when power
supply of WOP is turned on. Thus, the time of Trip mode, Read mode and Write mode cannot
be displayed correctly unless setting the correct time in Option mode after power supply of
WOP is turned on. However, there is no influence for operating except displaying correct time.
When replacing the battery, please take off the battery cover by removing one screw of the
operator backside. Please take out the old battery with a thin minus driver, and be careful not to
damage PCB and any part on the PCB. The positive (+) pole of the battery (flat one) must be
installed upward, the negative (-) pole face to substrate. And inserting the battery, press the
battery to reach the edge of the metal case. In addition, please do not touch it because the pin
adjacent to a battery is only for an examination of factory shipment. (Refer to Fig. 7)
Please dispose used battery according to local related laws and regulations.
