Reflecting surfaces
Electrically conducting surfaces (e.g. ceilings with metal con
-
structions) can reflect the RF signal.
►
The signal is reflected by the electrically conducting surface.
At worst, the blue signal and the red reflected signal are out of
phase when they reach the receiver so that the two signals
cancel each other out.
▷
If you have electrically conducting surfaces in a room,
make sure to position the receiver or the antenna wall
mounts so that such reflection effects are avoided.
If you have a reflecting ceiling, this can be achieved by po
-
sitioning the antennae closer to the ceiling.
Blocking effects from other transmitters
As with all wireless microphone systems, suboptimal position
-
ing of transmitters can lead to blocking effects. To avoid this,
please follow these recommendations:
▷
Position DECT telephone or DECT access points at least
7 m from the antennae.
▷
Position other wireless devices such as mobile phones at
least 1 to 2 m from the antennae.
▷
When transmitters are currently in use,
you must not posi
