Interferences and problems with operation
Problem & cause
Remedy
Distance between
transmitters and
receiver too long.
Reduce distance between
transmitters and receiver to
receive signal
High shielding
materials between the
units (thick walls,
steel, concrete,
isolating 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,
headset, 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 32ft extension cables
between units to the existing
cable lengths, as this will
increase the chance of 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
synchronize the base station
to the sensors for weather
data reception. If still no
signal, then change the
sensor batteries and
synchronize the units again.
Poor contrast LCD or
no reception or low
batteries in sensors
or receiver.
Check the LCD contrast
setting or change batteries
(check low battery indicator on
the LCD)
