■ When is battery replacement needed?
If the "Charge the battery!" or "Replace the batteries!" appears on the LCD, replace the
battery cartridge with a fully charged one or replace the dry batteries with new ones,
respectively.
If you leave the BHT-7000 without replacing the battery cartridge, the integrated
calendar clock or data will no longer be backed up so that the calendar clock will stop
or the "Contact your administrator. Note the error number. (XXXX)" will appear on the
LCD.

batteries within 3 minutes after the removal in order to avoid data loss.
