Denso BHT-400B-CE - Manual (Page 51)

Chapter 2 Getting Started the BHT and System Menu
• You may charge the rechargeable battery cartridge with the optional CU-400 communication unit
or optional CH-201 charger. For the charging procedure using the CU-400, refer to Chapter 5. For
that using the CH-201, refer to the "CH-201 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-400 or CH-201) 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.
