[. . . ] 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. Do not touch a power supply plug during thunder and lightning, as this may result in electric shock. 3 The AC power output is specified on the AC outlet of the unit. Never exceed the specified wattage on the unit when connecting equipment. Doing so may cause fire or property damage. When the Unit is in Use CAUTION When Installing the Unit 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. Do not operate the unit for an extended period of time with the sound distorting. This is an indication of a malfunction, which in turn can cause heat to generate and result in a fire. If dust is allowed to accumulate in the unit over a long period of time, a fire or damage to the unit may result. If dust accumulates on the power supply plug or in the wall AC outlet, a fire may result. 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. 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. Do not block the upper panel ventilation slots in the unit's cover. Doing so may cause heat to build up inside the unit and result in fire. 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. 4 2. GENERAL DESCRIPTION TOA's BG-115 and BG-130 are mixer/power amplifiers, and can mix up to three signals. Rated at 15 watts (BG-115) and 30 watts (BG-130), these amplifiers are ideal for applications that require small sound reinforcement systems. Setting the Mic/Tel selector switch to the "TEL" position allows the BG-115 (BG-130) to function as an amplifier for paging made from the telephone. [. . . ] 4x16 screw included in MB-25B-J MB-25B-J MB-25B-J PF-511 perforated panel (1-unitsize) When mounting two or more amplifiers in the rack, insert the Perforated Panel PF-511 between amplifiers for ventilation inside the rack. Contact the shop from where the amplifier was purchased as to the Perforated Panel. 10 12. VOLUME SETTING Output levels are adjustable with individual volume controls. For music play or announcement, adjust the corresponding volume control so that the signal indicator lights intermittently. [. . . ]
