6. Problems and interference with operation
Problem & cause
Remedy
Poor response inaccurate readings
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.
Neighbours using electrical devices operating at the same
signal frequency can also cause interference with reception
Poor contrast LCD or no reception or
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.).
