INSTRUCTION MANUAL

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 re or electric shock.

• Use the unit only with the voltage specied on the unit. Using a voltage higher than that which

is specied may result in re 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 re 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 re 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 re 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.

• 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 re or electric shock.

• Do not insert nor drop metallic objects or ammable materials in the ventilation slots of the

unit's cover, as this may result in re or electric shock.

• Do not touch a plug during thunder and lightning, as this may result in electric shock.

• To prevent possible hearing damage, do not listen at high volume levels for long

periods.

When Installing the Unit

• Never plug in nor remove the power supply plug with wet hands, as doing so may cause

electric shock.

• When unplugging the power supply cord, be sure to grasp the power supply plug; never pull

on the cord itself. Operating the unit with a damaged power supply cord may cause a re or

electric shock.

• When moving the unit, be sure to remove its power supply cord from the wall outlet. Moving

the unit with the power cord connected to the outlet may cause damage to the power cord,

resulting in re or electric shock. When removing the power cord, be sure to hold its plug to

pull.

• 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 re or electric shock.

• Replace the battery only with the TOA BP-900A. Using a battery other than designated may

cause it to explode. When you discard batteries, please contact the local dealer from whom

you bought.

When the Unit is in Use

• Do not place heavy objects on the unit as this may cause it to fall or break which may result

in personal injury and/or property damage. In addition, the object itself may fall off and cause

injury and/or damage.

• Make sure that the volume control is set to minimum position before power is switched on.

Loud noise produced at high volume when power is switched on can impair hearing.

• Use the dedicated AC adapter AD-0910 for the unit. Note that the use of other adapter may

cause a re.

• When the unit is not in use for 10 days or more, or when the AC power is used for operating

the unit, be sure to take the batteries out of the unit because battery leakage may cause a

re, personal injury, or contamination of environment.

• If dust accumulates on the power supply plug or in the wall AC outlet, a re may result. Clean

it periodically. In addition, insert the plug in the wall outlet securely.

• Switch off the power, and unplug the power supply plug from the AC outlet for safety purposes

when cleaning or leaving the unit unused for 10 days or more. Doing otherwise may cause a

re or electric shock.

Indicates a potentially hazardous situation which, if mishandled, could

result in moderate or minor personal injury, and/or property damage.

CAUTION

only.

• Priority Speech key to take precedence over Delegate units.

• Status after priority speech, Priority Chime ON/OFF function, and priority speech key operation

mode settable by a DIP switch.
