Replacing the Battery
Replace the battery within 40 hours if a battery alarm occurs. If it is within 30 minute after tur-
ing on the electricity after the power was turned off for more than 2 days, replace the battery
immediately.
(The battery alarms appear on the programing pendant display and LED on the system con-
trol board is turned on.)
Replacement Procedure
1. Disconnect the battery connector (BAT) and remove the battery.
2. Mount the new battery and connect the battery connector.
Although the CMOS memory is backed up by super capacitor, the battery must be
replaced as soon as the battery alarm occurs. The job data and other data may be lost if
the battery is left for more than 40 hours.
