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 op-
timum conditions.
The following conditions may result in
a reduced range:
- Signal transmission through buil
ding structures or vegeta tion
- Interference from TVs, computer
monitors and mobile phones.
Under certain circumstances, this
may prevent the receiver from fun-
ctioning 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 cancel-
led 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 sourcesof radio
waves which can disrupt the origi-
nal 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 ra dio transmit-
ter, in order to achie ve the greatest
possible range from the radio trans-
mitter:
- The radio transmitter should not be
set up close to devices which emit
powerful interference signals, such
as TVs, computer monitors or mo-
bile phones.
- The radio transmitter should not
be placed on metallic objects, sin-
ce 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.
