The transmitter for the Radio-lisa con-
verter are designed to have a radio
signal range of 80 meters under opti-
mum 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 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 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.

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 mob-
ile 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 buil ding
as possible, at a medium height in
the room.
