Safety Symbol and Message Conventions Safety symbols and messages described below are used in this manual to prevent bodily injury and property damage which could result from mishandling. Before operating your product, read this manual first and understand the safety symbols and messages so you are thoroughly aware of the potential safety hazards. WARNING Indicates a potentially hazardous situation which, if mishandled, could result in death or serious personal injury. 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. • To prevent lightning strikes, install the unit at least five meters away from a lightning rod, and yet within the protective range (angle of 45°) of the lightning conductor. Lightning strikes may cause a fire, electric shock or personal injury. • 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. 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. • 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 touch a plug or antenna during thunder and lightning, as this may result in electric shock. CAUTION Indicates a potentially hazardous situation which, if mishandled, could result in moderate or minor personal injury, and/or property damage. The servicing instructions are for use by qualified personnel only. To reduce the risk of electric shock do not perform any servicing other than that contained in the operating instructions unless you are qualified to do so. Refer all servicing to qualified service personnel. 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.
