• When moving the unit, be sure to remove its power
supply cord from the wall outlet. Moving the unit
with the power cord connected to the outlet may
cause damage to the power cord, resulting in fire or
electric shock. When removing the power cord, be
sure to hold its plug to pull.
• Do not block the supplied AC adapter's ventilation
slots. Blocking air flow to these slots will cause
heat to build up in the adapter, possibly resulting in
fire.
• Avoid installing the unit in humid or dusty locations,
in locations exposed to the direct sunlight, near the
heaters, or in locations generating sooty smoke or
steam as doing otherwise may result in fire or
electric shock.

injury and/or damage.
• If dust accumulates on the power supply plug or in
the wall AC outlet, a fire may result. Clean it
periodically. In addition, insert the plug in the wall
outlet securely.
• Switch off the power, and unplug the power supply
plug from the AC outlet for safety purposes when
cleaning or leaving the unit unused for 10 days or
more. Doing otherwise may cause a fire or electric
shock.

that the use of other adapter may cause a fire.
• Remove the power supply plug of charger from the
AC outlet after charging completion, as doing
otherwise may cause a fire.

2. GENERAL DESCRIPTION
The TOA BC-900 is a dedicated battery charger for BP-900 lithium-ion batteries used in the TS-801 and TS-
901 Chairman Units, and TS-802 and TS-902 Delegate Units of TOA's Infrared Conference System.
The BC-900 features an exclusive charging system for lithium-ion batteries, and permits up to 8 batteries to be
simultaneously charged within up to 5 hours.
3. HANDLING PRECAUTIONS
• Use the unit in locations where the temperature is between 0 and +40°C.
• Avoid installing the Battery Charger in locations exposed to vibration. Batteries may not be correctly charged
due to poor contact.
• To clean, be sure to first switch off the unit's power, then wipe with a dry cloth. When the unit gets very dirty,
use a cloth damped in a neutral cleanser. Never use benzene, thinner or chemically-treated cleaning cloth
because such volatile liquids could deform or discolor the unit.
• Clean the charging terminals periodically with a dry cotton swab. Dirty terminals could cause bad contact,
thus preventing batteries from being correctly charged.
