Incorrect handling of the battery cartridge could cause the batteries to generate heat or smoke,
or to rupture or burn. This is DANGEROUS. Be sure to observe the following:
Never disassemble or modify the battery cartridge.

Never connect the positive (+) and negative (-) terminals of the battery cartridge with a wire or

other metallic materials.
Do not carry or store the battery cartridge together with ballpoint pens, necklaces, coins,

hairpins, or anything else metallic.
Never burn or heat the battery cartridge.

Do not use or leave the battery cartridge anywhere there is excessively high temperature

(60°C or higher), such as near fire or stoves.
Do not put the battery cartridge into water of any kind or moisten it.

Never charge the battery cartridge near a fire or anywhere exposed to direct sunlight.

Do not stick a needle into the battery cartridge, hammer at it, or tread on it.

Do not let the battery cartridge undergo any shock or impact or throw it at something hard.

Do not use battery cartridges that are deformed, scratched or cracked remarkably.

Solder nothing to the battery cartridge directly.

If battery fluid leaks from the battery cartridge and it gets into your eyes, rinse them with clean

water thoroughly without rubbing and then consult a doctor immediately. Otherwise, you may
damage your eyes.
Mishandling of the charger may result in charger overheating, smoke generation, blowout or
combustion. Please read the following item prior to use.
Terminate charging if not completed even after the specified time has elapsed.

The BHT is equipped with a back-up battery used to back-up the internal memory and calendar
 Note 

clock when the battery cartridge is removed or the battery voltage falls below the stipulated
level.
It is therefore necessary to charge the internal back-up battery when using the BHT for the first
time or when it is left unused for long periods of time.
The back-up battery is charged automatically when a fully-charged battery cartridge is loaded.
To ensure that the back-up battery is fully charged, do not remove the battery cartridge for at
least 10 minutes when using the BHT for the first time or when using it after long periods of
time.
If you leave the BHT without the battery cartridge for a long time, the data stored in the memory

may not be restored and the message "Contact your administrator. Note the error number.
(XXXX)" or "Set the current date and time." may appear on the LCD.
Refer to Chapter 6 "Maintenance" – 6.3 "Using the BHT after Long Periods" for details of

handling the BHT after long periods of time.
Avoid storing the battery cartridge in high-temperature locations. The battery capacity may

decrease.
Do not touch the BHT, battery, or charger terminals by hand or get them dirty. Doing so may

result in a BHT operation defect or battery cartridge charging failure. It is recommended that dirt
on the battery cartridge terminals or BHT battery terminals be periodically wiped with a soft, dry
cloth.
