interference and/or obstacle in-between
the Main Unit and Remote Sensor (e.g.,
double glass protection or reinforced
concrete wall); or
(2) Batteries of the Remote Sensor are being
discharged
Another Remote Sensor using the same
frequency and same ID code is being in use
within the effective area
Selected Channel is already used by another
Remote sensor
(1) The measurement method is different
(2) The area under evaluation is different or
being influenced by climate
(1) (i) Move the Main Unit away from any
source of interference such as DECT
phone, mobile phone; and/or (ii) Move
the Remote sensor nearer to the main
unit and start SEARCH mode in the
Main Unit
(2) Check LED of Remote Sensor. Replace
with new batteries if it does not flash
in one minute
Place the Remote Sensor closer to the Main
Unit. Then reset the Remote Sensor and
activate SEARCH mode in the Main Unit
Select another free channel via the Channel
switch. Then reset the Remote Sensor and
activate SEARCH mode in the Main Unit
(1) Use the same instruments with
consideration of the tolerance of
