9. Battery exchange
There is a real time clock IC built-in. The power is supplied by a battery when outside power supply
is turned off
.
When the battery comes to its life, the clock IC does not renew the time when power
supply of LCD digital operator is turned off.
The clock date stored in the IC will be reset to a default value January 1, 2001 when power supply of
LCD digital operator is turned on. Thus, the time of Trip mode, Read mode and Write mode cannot
be displayed correctly unless the time is set properly in Option mode after power supply of LCD digital
operator is turned on. However, there is no special bad influence for operating except displaying
proper time.
When exchanging the battery, please disassemble the case by removing four screws backside of the
operator. The plus pole of the battery (flat one) must be installed. Please take out the old battery using
a thin minus driver, and be careful not to damage PCB and any part on the PCB.
