Putting the Set 840-TV system into operation
Putting the Set 840-TV system into
operation
Setting up the transmitter
왘Choose a suitable place near your sound source (e.g. TV).
왘Do 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 stethoset
receiver are in the same room, so you can move around
freely in the home or outside in the garden.
When the stethoset receiver leaves the range of the trans-
mitter, it produces warning signals and then automatically
switches off after 3 minutes.
One transmitter can be used to transmit to several
stethoset receivers on the same frequency.
