Putting the Set 900 into operation

Setting up the transmitter

왘 Place the transmitter so that:

– there are no obstacles in the light path between trans-

mitter and receiver and

– transmitter and receiver are not exposed to direct

sunlight. Direct sunlight may interfere with the reception and may damage the transmitter.

If you are using a plasma TV screen: Plasma TV screens radiate an infra-red signal that can

adversely affect the transmission quality.

왘 Make sure that the transmitter is placed as far as

possible from your plasma TV screen.

왘 If necessary, use a standard extension cable (3.5 mm

stereo jack plug) to reduce the distance between transmitter and receiver. This extension cable is available from your Sennheiser dealer.

Note:

One transmitter can be used to transmit to several receivers on the same frequency.
