High-quality GaAlAs transmitting diodes have been arranged in 12 independent groups to ensure re liable transmission. A malfunction indicator is triggered when the radiating power is reduced by more than 30 %. Technical Data IR diodes............................................................... 132 GaAlAs Average radiating power ............................................... 5 W Operating voltage.......................... 85 – 260 V, 50 – 60 Hz Current consumption – operation.................

To reduce interference and to improve the signal-to-noise ratio, SK 3063-U transmitters are equipped with the "HiDyn plus" noise reduction system. In combination with a receiver which is also equipped with this system (e.g. EM 3031/32-U / EM 3532-U), a connection can be established, which is characterised by excellent operational reliability and supreme transmission quality. FEATURES: • Metal injection-moulded casing with quick-change energy pack • State-of-the-art PLL technology, 16 switchable

The transmitter features an automatic on/off function. When the transmitter is turned on, its green LED lights up. Make sure to turn off the headphones after each use to avoid discharging the batteries. Reception Adjust the receiver channel with the TUNE control on the headphones. If reception is subject to interference, change the transmission channel. To do so, set the switch at the bottom of the transmitter to another position and re-adjust the receiver channel. Some electronic devices (e.g.

of audio enjoyment ■ Transmitter recharges the headphones plus an additional accupack ■ Headphones automatically switch on and off when they are put on/removed ■ Includes short instructions and colour-coded sockets and plugs for quick set-up and connection ■ Very lightweight stethoset headphones, extremely comfortable to wear even for extended listening ■ Ideal for wearers of glasses ■ Suitable for plasma TVs □H SENNHEISER

The transmitter easily connects to TV sets or hi-fi systems and transmits sound within a range of up to 100 metres. Users can to listen to the news through walls and ceilings, for example, while in the kitchen or out in the garden. Operation of the system is easy and straightforward, e.g. the headphones automatically switch on when they are put on. The transmitter features a compression button for further enhancing speech intelligibility. The RS 4200-2 has the same features as the RS 4200 but in

To do so, set the switch at the bottom of the transmitter to another position and re-adjust the receiver channel. Some electronic devices (e.g. televisions) can cause interference to your wireless headphone system. If this happens, increase the distance between the transmitter and the interference source.
