Shutdown due to low battery
Problem
When the BHT is switched on or being on (including during execution
of a program), the battery output level has lowered so that the BHT no
longer operates.
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
Replace or recharge the battery cartridge. (For the charging
procedure, refer to Chapter 5, Section 5.5.)
Calendar clock stopped
Problem
The calendar clock integrated in the BHT has stopped because:
- the battery cartridge had been removed for a long time, or
- the rechargeable battery cartridge had not been recharged for a
long time
The indication of 00/01/01 00:00 will change depending upon
the calendar clock state.
Solution
Set the calendar clock (refer to Chapter 2, Section 2.3.2).
