12.1 Low Battery Warning
■ BHT-3000
If the battery voltage is below the specified level when the BHT-3000 is powered on, the
"Battery voltage has lowered" message appears on the LCD.
If the battery voltage drops while the BHT-3000 is in operation, the beeper beeps three
times every 10 seconds.
If you keep using the BHT-3000 without battery replacement after the above warning, the
BHT-3000 displays the "Replace the batteries" message on the LCD and turns itself off
automatically.
Refer to the "BHT-3000 User’s Manual."
■
BHT-4000
If the output voltage of the Ni-Cd battery cartridge or dry battery cartridge drops below the
specified level, the BHT-4000 displays the "Charge the battery!!" message, beeps five
times, and then turns itself off automatically.
Refer to the "BHT-4000 User’s Manual."

specified level, the BHT-5000 displays the "Charge the battery!" message or "Replace the
batteries" message, respectively, beeps five times, and then turns itself off automatically.
Refer to the "BHT-5000 User’s Manual."
■
BHT-6000/BHT-6500
If the output voltage of the battery cartridge drops below a specified lower level limit when
the BHT-6000/BHT-6500 is in operation, the BHT displays the Level-1 message "Battery
voltage has lowered." on the LCD and beeps three times. After that, it will resume previous
regular operation.
If the battery output voltage drops further, the BHT-6000/BHT-6500 displays the Level-2
message "Charge the battery!" or "Replace the batteries!" (when driven by Ni-MH battery
cartridge or dry batteries, respectively), beeps five times, and then turns itself off automati-
cally.
Refer to the "BHT-6000 User’s Manual" or "BHT-6500 User’s Manual."
■
BHT-7000/BHT-7500
If the output voltage of the battery cartridge drops below a specified lower level limit when
the BHT-7000/BHT-7500 is in operation, the BHT displays the Level-1 message "Battery
voltage has lowered." on the LCD and beeps three times. After that, it will resume previous
regular operation.
If the battery output voltage drops further, the BHT-7000/BHT-7500 displays the Level-2
message "Charge the battery!" or "Replace the batteries!" (when driven by the lithium-ion
battery cartridge or dry battery cartridge, respectively), beeps five times, and then turns
itself off automatically.
Refer to the "BHT-7000 User’s Manual" or "BHT-7500 User’s Manual."
