Care And Maintenance; Specifications - La Crosse Technology WS-1912 Instruction Manual

For best results, the rain sensor should be securely mounted onto a horizontal surface
about 39.37" (1 meter) above the ground (or higher) and in an open area away from trees
or other coverings where rainfall may be reduced causing inaccurate readings.
When securing into place, check that rain excess will not collect and store at the base of
the unit but can flow out between the base and the mounting surface (test by pouring
clean water).
After mounting the rain sensor and placing battery, the rain sensor is now operable. For
testing purposes, very slowly pour a small amount of clean water into the rain sensor
funnel. The water will act as rainfall and will be received and displayed at the base station
i.e. when the reading interval is reached.

CARE AND MAINTENANCE:


Extreme temperatures, vibration and shock should be avoided as these may cause
damage to the unit and give inaccurate forecasts and readings.

Precautions shall be taken when handling the batteries. Injuries, burns, or property
damage may be resulted if the batteries are in contact with conducting materials,
heat, corrosive materials or explosives. The batteries shall be taken out from the unit
before the product is to be stored for a long period of time.

Immediately remove all low powered batteries to avoid leakage and damage.
Replace only with new batteries of the recommended type.

When cleaning the display and casings, use a soft damp cloth only. Do not use
solvents or scouring agents as they may mark the LCD and casings.

Do not submerge the unit in water.

Special care shall be taken when handling a damaged LCD display. The liquid
crystals can be harmful to user's health.

Do not make any repair attempts to the unit. Return them to their original point of
purchase for repair by a qualified engineer. Opening and tampering with the unit may
invalidate their guarantee.

Never touch the exposed electronic circuitry of the device, as there is danger of
electric shock, should it become exposed.

Do not expose the units to extreme and sudden temperature changes, this may lead
to rapid changes in forecasts and readings and thereby reduce their accuracy.
