Denso BHT-100BW-CE User Manual page 34

• You may charge the rechargeable battery cartridge with the optional CU-7001 communication unit
or optional C-700/C-750 charger. For the charging procedure using the CU-7001, refer to Chapter
5. For that using the C-700/C-750, refer to the "C-700 User's Manual"/"C-750 User's Manual."
• If the "Charge the battery!" message appears after the BHT undergoes any shock or impact, turn the
power off and on and then check the battery output level. The battery may not have run out.
Only use the dedicated charger (CU-7001 or C-700/750) for
charging the rechargeable battery cartridge.
Using a different type of charger could cause battery-rupture or
leakage of battery fluid and result in a fire, bodily injury, or
serious damage to property.
Never charge a wet or damp rechargeable battery cartridge.
Doing so could cause the batteries to break, generate heat,
rupture or burn.
