Handling the battery cartridge
• Never disassemble or heat the battery
cartridge, nor p t it into fire or water;
doing so co ld ca se battery-r pt re or
leakage of battery fl id, res lting in a
fire or bodily inj ry.
• Do not carry or store the battery car-
tridge together with metallic ball-point
pens, necklaces, coins, hairpins, etc.
Doing so co ld short-circ it the termi-

or impact.
Doing so co ld ca se the batteries to break, generate heat, r pt re or
b rn.
• Only se the dedicated charger (CU-5001
or C-500) for charging the Ni-MH bat-
tery cartridge.
Using a different type of charger co ld
ca se battery-r pt re or leakage of bat-
tery fl id and res lt in a fire, bodily in-
j ry, or serio s damage to property.

battery cartridges.
Doing so co ld ca se heat, battery-r pt re, or fire.
• Never bring any metals into contact with the o tp t terminals.
Doing so co ld prod ce a large c rrent thro gh the CU, res lting in
heat or fire, as well as damage to the CU.
• Use the f rnished AC adapter only. Fail re to do so co ld res lt in
fire.
• Never se the CU on the line voltage other than the specified level.
