Startup
The converter lisa -> radio is imme-
diately ready for use after being con-
nected to a 230 V socket.
Transmission range
The transmission range of the radio
signals of the converter lisa -> radio is
designed for 80 metres under optimal
conditions.
The following conditions may result in
a reduced range:
- Signal transmission through building
structures or vegetation
- 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
unfavorable distance from surfaces
which reflect radio waves, for ex-
ample floors and walls. This may
lead to the signal wave being wea-
kened 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 origi-
nal signal.
- Having units operating at similar sfre-
quencies located close to one anot-
her may also result in mutual interfe-
rence.
Positioning
In order to attain as wide a range as
possible, you should follow the installa-
tion information below :
- The converter lisa -> radio should not
be positioned near devices which
emit strong interference signals such
as television sets, monitors or mobi-
le telephones.
- The converter lisa -> radio should
not be positioned on metallic objects
as otherwise the transmission range
is reduced by the metallic screening.
- Position the converter lisa -> radio
as centrally as possible in the house
and at a medium room height.
