How to replace the backup battery
If [UA 91: Low battery power] displays, replace the battery by following the procedure below:
1
Open the operation panel cover.
2
Remove the battery.
3
Set the new battery by placing it in the battery holder with the positive side facing down.
4
Push the battery all the way in and close the panel cover.

With a 13-bit absolute encoder or a 17-bit absolute encoder (SHA20 and FHA-Cmini
series)*, UA91 will be automatically reset after the battery is replaced.

With a 17-bit absolute encoder (SHA series (excluding SHA20)), UA91 will be reset by
resetting the alarm and reconnecting the power after the battery is replaced.
* In Version 2.x and earlier, after the battery is replaced, turning the power back ON releases
UA91.
