Chapter 2. Getting Started the BHT and System Mode
■ Low Battery Indication
Low battery indication—Level 1
If the battery output voltage drops below a specified lower level limit while the BHT is
in operation, the BHT displays the following Level 1 message for approx. 2 seconds
and beeps three times. After that, it will resume previous regular operation.
The battery recharge or replacement time will come soon. If the BHT is driven by the
rechargeable battery cartridge, recharge or replace it; if it is driven by the dry battery
cartridge, replace the dry cells.
Low battery indication—Level 2
If you continue to use the BHT without recharge or battery replacement after the Level
1 message appears, the BHT displays the following Level 2 message, beeps five times,
and then turns itself off. Depending upon the battery level, the beeper may not sound
five times.
If the BHT is driven by the rechargeable battery cartridge, recharge or replace it; if it is
driven by the dry battery cartridge, replace the dry cells.
