[Absolute Battery Charging]
Charge for at least 72 hours continuously if using for the first time, after replacing the battery, and
when power has been turned off for extended periods. The battery is charged while 24 VDC is
supplied to RCON.
If RCON power is turned OFF beyond the data retention time, the data will be lost, so charge
regularly.
The battery has a limited lifetime that gradually decreases data retention time. Replace the
battery when the retention time decreases significantly even if properly charged.
Refer to “Specifications Section Chapter 7, 7.4 General Specifications [How to Replace Absolute
Battery] (page A7-8)” for how to replace the absolute battery.
