Shutdown due to low battery
Problem
When the BHT is turned on or during execution of
programs, 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.
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 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
Contact your system administrator.
Abnormal shutdown
Problem
After shut down abnormally*, the BHT has been left
without the battery cartridge loaded, or with discharged
battery cartridge loaded, so unsaved data was lost.
( * "Normally shut down" refers to turned-off with the PW
key or by the auto power-off feature.)
Solution
Contact your system administrator.
