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.
