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 devices which
emit powerful interference sig-
nals, such as TVs, computer moni-
tors 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.
of the battery compartment, to the
required channel number. All trans-
mitters and receivers must be set to
the same channel.
Radio range
Note the following points when
using the
RF Repeater:
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.
