Putting the Set 840 S system into operation

Setting up the transmitter

왘 Choose a suitable place near your sound source (e.g. TV).

왘 Do not place the transmitter close to metal objects such

as shelf bars, reinforced concrete walls, etc. as this can decrease the transmitter’s range.

It is not necessary that the transmitter and receiver are in the same room, so you can move around freely in the home or outside in the garden.

When the receiver leaves the range of the transmitter, it produces warning signals and then automatically switches off after 3 minutes.

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