WB-2000-2
Thank you for purchasing TOA's Ni-MH Battery.
Please carefully follow the instructions in this manual to ensure safety use of the
battery and prevent environmental contamination caused by battery leakage or
rupture.
• The WB-2000-2 is a Ni-MH AA rechargeable battery pack (containing 2 pieces)
dedicated for use with TOA's WM-5225 and WM-5265 Wireless Microphones,
WM-5325 Wireless Transmitter, and WT-5100 Portable Receiver.
• For inserting batteries into the WM-5225, WM-5265, WM-5325, and WT-5100,
refer to the instruction manual enclosed with it.
• For charging batteries, refer to the instruction manual enclosed with the BC-
5000-2, BC-5000-6, and BC-5000-12 Battery Charger.
DANGER Indicates an imminently hazardous situation, which, if
not avoided, will result in death or serious injury.
1. SAFETY PRECAUTIONS
• Do not deform nor solder.
• Do not short-circuit.
• Do not heat nor put in fire.
• Do not dip into water nor wet the battery terminals.
• Do not use nor keep near fire or in locations where the temperature rises above
60°C (140°F) such as in a sun-heated car.
• Use the BC-5000-2, BC-5000-6, or BC-5000-12 Battery Charger when recharging.
• Use only with the specified equipment.
• Do not drop nor give a shock.
• If battery leakage gets in one's eyes, wash it away with clean water and consult a
doctor immediately. Doing otherwise may cause one's eyesight loss.
• Charge when using first after purchase or when using after left unused for a long
period of time.
• Battery operating duration may be short due to its self-discharge when left unused
for a long period of time even after fully charged.
• Using at room temperature (20±5°C or 68±9°F) is recommended. Using at 10°C
(50°F) or below will extremely reduce the battery operating duration.
• Once overdischarged, its usable capacity could not restore even after charge.
So, charging for about 5 minutes every 6 months is advisable when leaving it
unused for a long period of time.
• Do not recharge fully-charged battery. Doing so deteriorates its performance.
• When not in use, take it out of the unit, and store in locations free from moisture and
between -20°C and 30°C (-4°F and 86°F).
• Do not store in a fully charged state. Discharging as fully as possible before storage
is recommended. (Note that doing this will not lead to overdischarge of the battery.)
