User manual SENNHEISER AUDIOBEAM

[. . . ] At a distance of less than four meters in front of AudioBeam, ultrasonic frequencies may disturb the function of cardiac pacemakers and may cause damage to the hearing!Make sure that no-one can come closer than four meters to AudioBeam ­ especially when mounting the unit movably or rotatably. warning of life-threatening electrical shock!If AudioBeam is connected to the mains, opening AudioBeam may result in a life-threatening electric shock! [. . . ] The ultrasonic sound wave can travel undisturbed for at least 1 m before it strikes the first surface. The sound (including the reflections) can travel for at least 4 m before it strikes a human being !A minimum distance of 10 cm is maintained between AudioBeam and adjacent objects so that any heat generated can dissipate. Make sure that the air vents at the top and rear of the unit are not covered or blocked!A minimum distance of 1 meter is maintained between AudioBeam and combustible materials !AudioBeam is kept away from heat sources such as central heating radiators, spot lights and lamps. AudioBeam never gets damp or wet Mounting AudioBeam in a fixed position To ensure that AudioBeam is always orientated towards the correct area of interest, you should mount AudioBeam fixedly. Use a mounting plate for wall or ceiling mounting. For free installation, use a table or floor stand (see: , , Accessories" on page 16). Screw the mounting plate or the table or floor stand to the thread ¶. If necessary, use the interchangeable thread to do this. By using a gooseneck or swivel joint (see: , , Accessories" on page 16), directly orientate AudioBeam towards the correct area of interest or the reflection area. Mounting AudioBeam movably or rotatably Screw AudioBeam onto a drive mechanism or a rotating mechanism using the 5/8" thread ¶. use the interchangeable thread if necessary. Start up AudioBeam as described on page 15 and ensure that the distance sensor does not trigger in rotating mode (LED operation indicator ³ is constantly lit green). If the distance sensor triggers (LED operation indicator ³ lights up red): ³ Remove all objects from the rotating range scanned by AudioBeam up to a distance of 4m. If the distance sensor still triggers (LED operation indicator lights ³ up red again), you must turn off the built-in distance sensor as follows: Putting AudioBeam into operation If you turn off the built-in distance sensor, persons who come closer than 4 m to AudioBeam may be in danger from ultrasound. Always ensure that nobody can come closer than 4 m to AudioBeam across the entire rotating range! [. . . ] After the person has left this area, AudioBeam automatically turns on again after 30 seconds. You are operating the device in rotating mode and the distance sensor has triggered because objects or persons are located within the sensor range of the built-in distance sensor. o solve the problem , see: , , Mounting AudioBeam movably or rotatably" on page 14.
