La Crosse Technology WS-7015 - Manual (Page 12)

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 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 330 ft (100 m). 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 (WS-7015-
12) 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.
17. Disposal
If the Professional Remote Weather Station happens to become inoperable and must be
disposed of please do this in accordance with the valid legal regulations.
