Logger:
If the logger malfunctions, please check the batteries and, if necessary, start up again. It is advisable to
leave the device to rest for a few minutes and then to reinsert the batteries.
Please do not use rechargeable batteries. For the proper functioning of the device should be 1.5V.
Batteries are used.
Radio problems:
Radio problems could occur between the logger and a radio transmitter or between the logger and the
USB radio transceiver if the local conditions impair the radio signal too much.
A maximum radio range of up to 100 meters is possible for a transmitter and up to 10 meters for a USB
radio transceiver (each in free field). In practice, the maximum possible range is reduced to the actual
range by local conditions.
Possible impairments are:
Batteries:
If weak or faulty batteries are used, the optimal radio performance could also be impaired.
Visible obstacles:
Of course, every visible obstacle, depending on its thickness, structure and material properties, also
represents a corresponding impairment
should if possible
large metal / steel surfaces
(also
coated / steamed window panes) can be avoided.
Invisible obstacles:
The most common cause of problems is interference from electronic factors. Therefore, if possible,
there should always be some distance (1-2 meters) to large electronic devices in order to avoid
electromagnetic interference as far as possible. But also other radio devices within the
