ecution of program (System Mode or application),
the battery output level has dropped below a
specified lower level limit.
If low battery is detected, the BHT-7000

and beeps three times (for 0.1 second per
beep). After that, it will resume previous
regular operation.

soon, requiring replacement or recharge.
If the BHT-7000 is loaded with the rechargeable
battery cartridge, replace or charge it. (For the
charging procedure, refer to Chapter 5, Section
5.5.)
If the BHT-7000 is loaded with the dry battery car-
tridge, replace the dry cells.
