High shielding mate-
rials between the
units (thick walls,
steel, concrete, isolat-
ing aluminum foil and
etc.)
Find a different location for
sensors and/or receiver. See
also Item ‘Transmission
Range’ below.
Interference from
other sources (e.g.
wireless radio, head-
set, speaker, etc.
operating on the
same frequency)
Find a different location for the
sensors and/or base station.
Neighbors using electrical
devices operating on the
433MHz signal frequency can
also cause interference with
reception
No Reception after
adding extension
cables
Find a new location for the
sensors and/or base station.
Recommend not adding more
than 10 meter extension
cables between units to the
existing cable lengths as this
will increase the chance data
reception problems.
Reception then no
reception - loss of
transmission signal
from the sensor to the
base station
Press and hold the PLUS(+)
key for 2 seconds to synchro-
nize the base station to the
sensors for weather data
reception. If still no signal,
then change the sensor batter-
ies and synchronize the units
again.
Poor contrast LCD or
no reception or low
batteries in sensors
or receiver.
Check the LCD contrast set-
ting or change batteries
(check low battery indicator on
the LCD)
Quite frequently interferences are only of a temporary nature
and may be easily overcome. If there are wireless headsets,
remote babysitters or other devices working on 433MHz in
your house or in the vicinity, their switch-on time is mostly
limited. Furthermore most of these devices allow the change
to an interference-free frequency. Such measures will effec-
tively overcome interferences.
