Transmission Range; Cleaning And Maintenance - La Crosse Technology WS-2306 Operation Manual

Poor contrast LCD, or
no reception, or low
batteries in sensors or
receiver.
Quite frequently interferences are only of a temporary nature and may
be easily overcome. If there are wireless headsets, remote baby
monitors or other devices working on 433MHz in your house or in the
vicinity, their switch-on time is mostly limited. Furthermore most of
these devices allow the change to an interference-free frequency.
Such measures will effectively overcome interferences.

Transmission Range

The transmission distance from the thermo-hygro sensor to the base
station in open space under optimum conditions is 100 metres.
Although the signal transmission may travel though solid surfaces or
objects, the following points should be avoided if possible:
- High frequency interferences of any kind.
- High densities of trees.
- Double paned and UV coated windows, glass doors etc.
- Broadband 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 close by (example a neighbour's house) may
also influence reception.
- Poorly shielded PCs can cause interferences that will reduce or
in some cases stop reception.
- The transmitter and receiver should not be mounted on metal
surfaces as this will reduce transmission range.

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 rain sensor does not collect leaves or other dirt
by checking the funnel for blockages every now and then. 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 the bottom half of the rain sensor
attached nor the bottom part itself under running water. This
may bear the danger of water entering the unit's inner parts and
cause damages.
Check the LCD contrast setting or
change batteries (check low battery
indicator on the LCD)
