Low battery indication—Level 2
Problem
When the power is turned on or during execution
of program (System Mode or application), the bat-
tery output level has lowered.
If lower battery is detected, the BHT beeps
five times (for 0.1 second per beep) and then
turns itself off. Depending upon the battery
level, the beeper may not sound five times.
Solution
If the BHT 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 is loaded with the dry battery cartridge,
replace the dry cells.
