Low battery indication—Level 2
■ Problem
When the power is turned on or off or during ex-
ecution of programs (System Mode or applica-
tions), the battery output level has lowered to the
extent 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
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 or
- The battery cartridge had not been recharged for
a long time.
The indication “00/01/01 00:00” will vary
depending upon the calendar clock state.
■ Solution
Contact your system administrator.
