Low battery indication—Level 2
Problem
When the power is turned on or off or during ex-
ecution of program (System Mode or application),
the battery output level has lowered to the extent
that the BHT can no longer operate.
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.
Calendar clock stopped
Problem
The calendar clock integrated in the BHT has
stopped because:
- The battery cartridge had been removed for a
long time,
- The rechargeable battery cartridge had not been
recharged for a long time, or
- The dry cells in the dry battery cartridge had not
been replaced.
The indication of 00/01/01 00:00 will change
depending upon the calendar clock state.
Solution
Set the calender clock (refer to Chapter 2, Subsec-
tion 2.3.2).
