Radio range
4
The transmitter is designed to have a radio signal range of 80 metres un-
der optimum conditions.
The following conditions may result in a reduced range:
- Signal transmission through building structures or vegetation.
- Interference from TVs, computer monitors and mobile phones. Under cer-
tain circumstances, this may prevent the receiver from functioning at all.
- Positioning of the transmitter at an unfavourable distance from surfaces
which reflect radio waves, for example floors and walls. This may lead to the
signal wave being weakened or even cancelled out by the reflected wave.
- Metallic objects reduce the range due to the shielding effect of the metal.
- In densely built-up areas, there may sometimes be sources of radiation
that can distort the original signal.
- Having units operating at similar frequencies located close to one an-
other may also result in mutual interference.
Channel selctor A, B, C
5
With the channel selector you can change the frequency of the transmit-
ter. If channel A is distorted you can change to another channel.
Transmitter
The channel selector is located on the rear side of the transmitter or re-
ceiver. Transmitter and receiver must both be set to the same channel.

Note:
If the transmitter is switched to another
channel, the receiver also has to be set to
another channel. (See specifications.)
