WARNING
CAUTION
When Installing the Unit
• Do not expose the unit to rain or an environment
where it may be splashed by water or other liquids,
as doing so may result in re or electric shock.
• Use the unit only with the voltage specied on
the unit. Using a voltage higher than that which is
specied may result in re or electric shock.
• Do not cut, kink, otherwise damage nor modify
the power supply cord. In addition, avoid using the
power cord in close proximity to heaters, and never
place heavy objects -- including the unit itself -- on
the power cord, as doing so may result in re or
electric shock.
• Avoid installing or mounting the unit in unstable
locations, such as on a rickety table or a slanted
surface. Doing so may result in the unit falling
down and causing personal injury and/or property
damage.
When the Unit is in Use
• Should the following irregularity be found during
use, immediately switch off the power, disconnect
the power supply plug from the AC outlet and
contact your nearest TOA dealer. Make no further
attempt to operate the unit in this condition as this
may cause re or electric shock.
· If you detect smoke or a strange smell coming
from the unit.
· If water or any metallic object gets into the unit
· If the unit falls, or the unit case breaks
· If the power supply cord is damaged (exposure of
the core, disconnection, etc.)
• To prevent a re or electric shock, never open nor
remove the unit case as there are high voltage
components inside the unit. Refer all servicing to
your nearest TOA dealer.
• Do not place cups, bowls, or other containers of
liquid or metallic objects on top of the unit. If they
accidentally spill into the unit, this may cause a re
or electric shock.
• Avoid inserting or dropping metal or combustible
objects or other foreign objects in the Charger’s
interior or battery receptacles, as this could result
in re or electric shock.
• Do not touch a power cord plug during thunder and
lightning, as this may result in electric shock.
• Stop charging if batteries are not fully charged
within 5 hours.
Continuously charging over 5 hours may cause
batteries to re, explode, leak, or heat.
When Installing the Unit
• Never plug in nor remove the power supply plug
with wet hands, as doing so may cause electric
shock.
• When unplugging the power supply cord, be sure to
grasp the power supply plug; never pull on the cord
itself. Operating the unit with a damaged power
supply cord may cause a re or electric shock.
WARNING
CAUTION

• 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 re or
electric shock. When removing the power cord, be
sure to hold its plug to pull.
• 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 re or
electric shock.
When the Unit is in Use
• Do not place heavy objects on the unit as this may
cause it to fall or break which may result in personal
injury and/or property damage. In addition, the
object itself may fall off and cause injury and/or
damage.
• If dust accumulates on the power supply plug or
in the wall AC outlet, a re 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 re or electric
shock.
• Use the dedicated AC adapter for the unit. Note that
the use of other adapter may cause a re.
• Remove the power supply plug of charger from
the AC outlet after charging completion, as doing
otherwise may cause a re.
• Risk of explosion if battery is replaced by an
incorrect type. Dispose of used batteries according
to the instructions.
2. GENERAL DESCRIPTION
The TOA BC-920 is a dedicated battery charger for BP-920 and BP-900A lithium-ion batteries used in the TS-
821 and TS-921 Chairman units, and TS-822 and TS-922 Delegate units of TOA's Infrared conference system.
The BC-920 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 rst 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.
