Possible interferences preventing correct display of transmitted measurement
values:
Undefined values after setting up.
In order to immediately receive defined data and ensure the correct assignment of
all data telegrams to their display section make sure, that the test mode of the Base
Station is only be terminated after all sensors have ended their test phase.
No reception – distance between transmitter and receiver too long.
Reduce distance between transmitter and receiver. Use Repeater to extend
transmission distance.
No reception – highly shielding materials between transmitter and receiver
(thick walls, steel concrete, isolating aluminum foil, etc.).
Find different location for transmitter and/or receiver. See also Item Transmission
Range.
Low batteries in transmitter or receiver.
Change batteries. Observe low battery indicator.
Transmitter is superposed by interfering sources (e. g. wireless radio, headset,
speaker, etc.).
Remove interfering source. Find different location for transmitter and/or receiver.
Has no reception taken place for the last 12 hours, the respective measuring point
is shut down and no measuring value will show, since the system is assuming a
sensor no longer in existence. In order to save battery power there will be no more
reception attempts. Every day at 8.00h a.m. and 6.00h p.m. the receiver will
autonomously start a new synchronization whereby a sensor not received for more
than 12 hours will be reactivated.
Note!
Every newly added Remote Sensor (e.g. after a battery change) will
automatically be entered into the system and its respective data will be
displayed.
Quite frequently interferences are only of a temporary nature (e.g. R/T operation) or
can easily be overcome. If there are wireless headsets, remote babysitters or other
devices working on a 433MHz basis in your house or vicinity, their switch-on time
is mostly limited. Furthermore most of these devices allow the change to an
interference-free frequency. Such measures will effectivelly overcome interferences.
Remote Sensor does interfere with other devices in the 433MHz range.
The transmissions of the Remote Outdoor Sensor can temporarily (for about 200
