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 fire 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 fire 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 fire or electric
shock. 

• Leave the installation of an antenna to your TOA dealer because the installation requires expert knowledge.

The falling of an antenna may cause electric shock. 

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. 

• Never open the unit case as there are high temperature parts inside the unit, which may cause a burn if

touched. Refer all servicing to your nearest TOA dealer.

• Use the dedicated AC – DC adapter for the unit. Note that the use of other adapter may cause a fire.

• If dust accumulates on the power supply plug or in the wall AC outlet, a fire 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. A fire or electric shock may result. 

Indicates a potentially hazardous situation which, if mishandled, could
result in moderate or minor personal injury, and/or property damage.
