A newly added radio sensor (e.g. following a change of batteries) is auto-
matically accepted by the system and the related data is displayed.
Faults are often restricted to limited periods (radio communication) or can be
easily eliminated. If a unit, e.g. radio headphones, remote babysitter, etc is oper-
ated your house or a neighbor's at 433 MHz, the period of activity is normally
limited. Most of these units can be changed to an interference-free frequency.
Such measures can normally eliminate faults effectively.
Radio sensor interferes with other units in 433 MHz range
The transmissions from radio sensors can cause short-term interference on units
operating on the same channel (every 3 minutes for approx. 200 ms).This inter-
ference is negligible. If possible, change the channel on the unit experiencing
interference.
Recharging batteries in the outdoor sensors
The vanadium-lithium battery integrated in the outdoor sensors is capable of
covering power requirements during periods of darkness for several months so
that, under normal conditions, no recharging is necessary.
However, if the battery is discharged following a long period in storage in dark-
ness, recharge it by exposing the solar cell to sunlight for several hours, without
the activating magnets being inserted.
