• Never disassemble or heat the battery cartridge, nor put it into fire or water; doing so
could cause battery-rupture or leakage of battery fluid, resulting in a fire or bodily injury.
• Do not carry or store the battery cartridge together with metallic ball-point pens,
necklaces, coins, hairpins, etc.
Doing so could short-circuit the terminal pins, causing the batteries to rupture or the
battery fluid to leak, resulting in a fire or bodily injury.
• Avoid dropping the battery cartridge or letting it undergo any shock or impact.
Doing so could cause the batteries to break, generate heat, rupture or burn.
• Never charge the rechargeable battery cartridge where any inflammable gases may be
emitted; doing so could cause fire.
• Do not use batteries or power sources other than the specified ones; doing so could
generate heat or cause malfunction.
• The BHT has an integrated backup power source which backs up the memory and calendar clock in
the BHT when no battery cartridge is loaded or the voltage level of the battery cartridge drops
below the specified level. The backup power source is automatically charged by the battery
cartridge.
When you first load the battery cartridge after purchase or you load it after leaving the BHT unused
for a long time, do not remove the battery cartridge for approx. 48 hours after that loading. This is
for charging the memory backup source integrated in the BHT.
• Avoid storing the rechar gea ble bat tery ca rtridge in a hot pl ace ( 50°C, 12 2°F or higher). The battery
capacity may be decreased.
• Do not touch the charge terminals of the rechargeable battery cartridge or stain those terminals.
Doing so could result in a charging failure.
