Chapter 2. Getting Started the BHT and System Mode
2.3.6 Battery Replacement Notes
■When is battery replacement needed?
If the "Charge the battery!" or "Replace the batteries!" appears on the LCD, replace the rechargeable battery cartridge with a fully charged one or replace the dry cells with new ones, respectively.
If you leave the BHT without replacing the rechargeable battery cartridge or dry cells, the integrated calendar clock or data will no longer be backed up so that the calendar 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 or new dry cells within 3 minutes after the removal to avoid data loss.
After battery replacement, turn the BHT on and check its operation.
■If you will use the BHT more than one time per month:
Keep the battery cartridge loaded in the BHT.
■If you will not be using the BHT for more than one month:
Remove the battery cartridge from the BHT and then store the BHT. To do so, be sure to follow the procedure given below.
