Battery Replacement Notes
■ When is battery replacement needed?
If the "Charge the battery!" appears on the LCD, replace the rechargeable bat-
tery cartridge with a fully charged one, respectively.
If you leave the BHT without replacing the rechargeable battery cartridge, the
integrated calendar clock or data will no longer be backed up so that the calen-
dar clock will stop or the message "Contact your administrator. Note the error
number. (XXXX)" will appear on the LCD.
Be sure to turn the BHT off before battery replacement.
Replace the battery cartridge quickly. Load a charged battery cartridge
within 3 minutes after the removal to avoid data loss.
After battery replacement, turn the BHT on and check the BHT operation.
