Radio range
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 vegeta tion.
- Interference from TVs, computer
monitors and mobile phones.
Under certain circumstances, this
may prevent the receiver from func-
tioning 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 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 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 mobi-
le 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.
