Thank you for purchasing TOA's Chairman Units and Delegate Units.
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.
Indicates a potentially hazardous situation which, if mishandled,
could result in death or serious personal injury.
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.
• 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.
• 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.
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 your nearest TOA dealer.
