5. Troubleshooting
Possible disruptions that can hamper proper display of the transmitted
measured values are:
No reception - the distance between the transmitter and receiver is too much
or too less (<3 ft., 1 m).
Reduce or increase the distance between the transmitter / receiver.
No reception - there are highly resistant materials (thick walls, steel concrete, ...)
located between the transmitter and the receiver
Relocate the transmitter or receiver. Also see chapter 6 ("Range").
No reception - transmitter batteries are empty.
Replace batteries.
No reception - transmitter is covered by the disturbance source
(Wireless device, wireless headphone/ loudspeaker)
Remove the source of the fault and look for another position for the transmitter and
receiver. Such disturbances are only for a short period (wireless traffic) or can be
rectified in a very simple manner. Any wireless headphones, wireless baby phones
or similar devices are operated at a frequency of 916.5 MHz in your house or in the
vicinity only for a short duration. Most of these devices are enabled for exchang-
ing signals at an interruption-free frequency. Such a measure can effectively fade
out all interruptions.
No reception – Log in of sensor was not successful.
Execute log in procedure again. Refer page 13 of the manual and follow the instructions of
the receiver station.
