When Installing the Unit
Applicable to Central unit, Conference unit, Battery charger, and AC adapter
When the Unit is in Use
Applicable to Lithium-ion battery
• Should the following irregularity be found during use, immediately switch off the power, take the batteries out
of the unit, and keep them away from fire. Failure to do so may cause a fire or explosion.
· If you find battery leakage, discoloration, deformation or damage.
· If you detect smoke or a strange smell coming out from the batteries.
• Do not deform, modify, nor solder the batteries. Doing so may damage the battery's safety or protector
mechanism, causing the batteries to fire, leak, or explode.
• Never short the positive and negative terminals with a wire or other metallic objects. Also, avoid carrying or
keeping the batteries with metallic objects such as necklaces or hair pins. Doing so may cause the batteries
to fire, explode, leak, or heat.
• Never heat the batteries nor throw them into a fire. Doing so may damage the battery's gas relief valve or
safety mechanism, causing the batteries to fire or explode.
• Do not dip the batteries into water nor wet the battery terminals. This may corrode the batteries, possibly
causing them to fire, explode, leak, or heat.
• Note correct polarity (positive and negative orientation) when inserting the batteries into a battery charger.
Doing otherwise may cause them to fire, explode, leak, or heat.
• Do not use, keep, nor leave the batteries near fire or in locations where the temperature rises above 60°C
such as in a sun-heated car. Doing so may damage the battery's safety or protector mechanism, causing the
batteries to fire, explode, leak, or heat.
• Be sure to use the BC-900 Battery charger when recharging the batteries. Using other battery charger may
cause them to fire, explode, leak, or heat.
• Use the batteries only with the equipment specified. Failure to do so may cause the batteries to fire, explode,
leak, or heat.
• Do not drop the batteries nor give them a shock. Doing so may damage the battery's safety or protector
mechanism, causing the batteries to fire, explode, leak, or heat.
• There is a fear of loosing one's eyesight if a battery leakage gets in one's eyes. Wash it away with clean water
and consult a doctor immediately. If a battery leakage stains one's skin or clothes, wash it away with clean
water as there is a fear of impairing the skin.
Indicates an imminently hazardous situation, which, if not avoided,will
