READ ME FIRST
Thank you for purchasing TOA’s Window Intercom System.
Please carefully follow the instructions in this manual to ensure long, trouble-free use of your equipment.
1. SAFETY PRECAUTIONS
• Before installation or use, be sure to carefully read all the instructions in this section for correct
and safe operation.
• Be sure to follow all the precautionary instructions in this section, which contain important
warnings and/or cautions regarding safety.
• After reading, keep this manual handy for future reference.
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.
• Since the unit is designed for indoor use, do
not install it outdoors. If installed outdoors,
the aging of parts causes the unit to fall off,
resulting in personal injury. Also, when it gets
wet with rain, there is a danger of electric
shock.
• Avoid installing the Sub-Unit in locations
exposed to constant vibration.
Excessive vibration can cause the Sub-Unit
to fall, potentially resulting in personal injury.
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 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
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.
Indicates a potentially hazardous situation
which, if mishandled, could result in death
or serious personal injury.
