2. SAFETY PRECAUTIONS
CAUTION
Indicates a potentially hazardous situation which, if
mishandled, could result in moderate or minor personal
injury, and/or property damage.
• 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 fire or electric shock.
WARNING
Indicates a potentially hazardous situation which, if
mishandled, could result in death or serious personal
injury.
• 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.
• 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.
• Since the unit is designed for in-door 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.
• Should the following irregularity be found during use,
immediately switch off the power of the TS-770 Central
unit, 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 comingfrom the
unit.
· If water or any metallic object gets into the unit
· If the unit falls, or the unit case breaks
· 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 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.
The TS-771 Chairman unit and TS-772 Delegate unit are
designed for use with the TOA Conference system.
Either the TS-773 Microphone (standard) or the TS-774
Microphone (long) can be selected for the microphone.
