Distance between transmitters and
receiver too
great.
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
headset, speaker
etc.
operating on the same frequency)
.
Find a different location for the sensors and/or base station.
Neighbo
u
rs using electrical devices operation on the same
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.
Poor contrast LCD or no reception
from sensors.
Low batteries in sensors or receiver.
Change batteries
.
Temperature, humidity, or air pressure
is incorrect.
Check/replace batteries. If multiple remote sensors are in use,
check location with corresponding
“boxed numbers”. Or move
away from sources of heat/cold. Adjust relative air pressure to a
value from a reliable source (TV radio, etc.).
