WARNING
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. (TS-
780 only)
• 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. (TS-780 only)
• 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. (TS-780 only)
• Since the unit is designed for in-door use, do not
use it outdoors. When it gets wet with rain, there is
a danger of electric shock.
When the Unit is in Use
• Should the following irregularity be found during
use, immediately switch off the TS-780’s power,
disconnect the power supply plug from the TS-780’s
AC outlet 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.) (TS-780 only)
· If it is malfunctioning (no tone sounds.)
• To prevent a fire or electric shock, never open nor
remove the unit case as there are high voltage
components inside 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 touch a power supply plug during thunder
and lightning, as this may result in electric shock.
