2. Open the battery case cover.
3. Remove the old battery and mount the new JZSP-BA01 battery as shown below.
4. Close the battery case cover.
5. After replacing the battery, turn OFF the control power supply to clear the absolute encoder battery error
alarm (A.830).
6. Turn ON the control power supply again.
