ms every 3 minutes) interfere with other devices working on the same channel.
These interferences are of very short duration and can thus be neglected. If possible,
the channel should be changed at the respective device.

15. Transmission Range

The transmission distance in open field with free range of sight between transmitter
and receiver reaches under optimum conditions 100 meters. Walls and even steel
concret constructions will be penetrated at a considerable loss of transmission
distance. A loss of distance can have the following reasons:
- High frequency interferences of any kind.
- Constructions of any kind or vegetation.
- Especially for the Wind Sensor the transmission distance can be influenced by
metal roofs or aluminum foil roof isolation.
- The distance of transmitter and receiver to conducting planes or object
(including the human body or the ground) does influence the transmission
characteristics and thus the transmission distance.
- Broad band interferences in municipal areas can reach levels reducing the
signal/noise ratio over the entire frequency band, thus also reducing the
transmission distance.
- Devices working at closely neighbouring frequencies may also influence
reception.
- Poorly shielded PCs can irradiate the receiver and thus reduce transmission
distance.
- For extension of transmission distance the optionally available Repeater can
be used.

16. Cleaning and Maintenance

- Clean the housing and screen of the Base Station only with a soft, damp cloth.
Do not use abrasives or solvents.
- Ensure that the Remote Rain Volume Sensor does not collect leaves or other
dirt. Remove the funnel from the Rain Sensor every now and then and clean it
under running water. Also clean the seesaw of the sensor with a damp cloth
and check by lightly tapping with your finger that it can move freely from side
to side.
Do not clean the funnel with attached bottom part of the Rain Sensor nor the
bottom part itself under running water. This may bear the danger of water
entering the unit's electronic parts.
- Do not immerse the Base Station in water.
- Please do not attempt any repairs on your own. It is recommended to have
repairs only performed by trained personnel at the point of purchase. Opening
or improper handling of the units will void the warranty.
