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 fire or electric shock.
• Use the unit only with the voltage specified on
the unit. Using a voltage higher than that which is
specified may result in fire 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 fire or
electric shock.
When the Unit is in Use
• Should the following irregularity be found during
use, immediately remove the AC power plugs (AC
power cords), disconnect the battery, and contact
your nearest TOA dealer. Make no further attempt
to operate the unit in this condition as this may
cause fire 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.)
· If it is malfunctioning (no tone sounds.)
• To prevent a fire or electric shock, never open the
unit case nor modify the unit. Refer all servicing to
qualified service personnel.
• 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 fire
or electric shock.
• Do not insert nor drop metallic objects or flammable
materials in the ventilation slots of the unit’s cover
as this may result in fire or electric shock.
• Do not touch a power supply plug during thunder
and lightning, as this may result in electric shock.
• When replacing the AC or DC fuse, be sure to use the
proper one among the following supplied fuses: AC
fuse T8A H, AC fuse T6.3A L, and Blade fuse 35 A.
Using any other fuse than supplied may cause fire or
electric shock.
• Handle or use the batteries properly.
Doing otherwise may cause leakage or explosion
of the batteries, resulting in a fire, personal injury,
damage to peripheral equipment, or contamination
of environment.
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 fire or electric shock.
• Do not block the ventilation slots in the unit’s cover.
Doing so may cause heat to build up inside the unit
and result in fire.
