When Installing the Unit
• Do not expose the unit to rain or an environment
where it may be constantly 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.
• Install the unit in a matching position. The unit
shall neither be installed in a position where the
calls can be released accidentially nor in a position
which the target group cannot access.
• The station shall be connected to the system's
power with a protective earthing connection.
• Mount the unit in a viable mounting plate or wall
whose structure is matching with the weight of the
substation.
• Fix the unit at the wall so that it can neither be
peeled off nor fall off.
When the Unit is in Use
• Should the following irregularity be found during
use, immediately switch off the system's power 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 panel as there are high voltage
components inside the unit. Refer all servicing such
as modification inside the unit to qualified service
personnel.
• Do not touch a plug during thunder and lightning,
as this may result in electric shock.
When Installing the Unit
• When unplugging be sure to grasp the plug; never
pull on the cord itself. Operating the unit with a
damaged cord may cause a fire or electric shock.
• Avoid installing the unit in dusty locations or 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.
• To avoid electric shocks, be sure to switch off the
system's power while connecting.
When the Unit is in Use
• Do not operate the unit for an extended period of
time with the sound distorting. This is an indication
of a malfunction, which in turn can cause heat to
generate and result in a fire.
