Radio range
Note the following points when
using the combi I RF transmitter:
The radio signals are designed to
have a range of 80 meters under
optimum conditions.
The following conditions may result
in a reduced range:
- Signal transmission through buil
ding structures or vegetation
- Interference from TVs, computer
monitors and mobile phones.
Under certain circumstances, this
may prevent the receiver from
functioning at all.
- Positioning of the transmitter at an
unfavourable distance from surfa-
ces 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.
- Particularly in towns and cities,
there may be many other sources
of radio waves which can disrupt
the original signal.
- Having units operating at similar
frequencies located close to one
another may also result in mutual
interference.

Positioning the radio
transmitter
Bear in mind the following points
when positioning the radio transmit-
ter, in order to achieve the greatest
possible range from the radio trans-
mitter:
- The radio transmitter should
not be set up close to devi-
ces which emit powerful
interference signals, such as
TVs, computer monitors or
mobile phones.
- The radio transmitter should
not be placed on metallic
objects, since otherwise the
radio range will be restricted
by metallic shielding.
- Position the radio transmitter
as close to the centre of the
building as possible, at a
medium height in the room.
