4. Gently pull the indoor weather station down to
lock the screw into place.
TROUBLESHOOTING
NOTE: For problems not solved, please contact La Crosse Technology.
Problem: The LCD is faint
Solution: Replace the batteries
Problem: No outdoor temperature/ humidity is displayed.
Solution: 1) Remove all batteries, reinsert into remote temperature/humidity sensor first, then
into the indoor weather station.
2) Place remote temperature/humidity sensor closer to indoor weather station.
3) Be sure all batteries are fresh.
4) Place remote temperature/humidity sensor and indoor weather station in position
so the straight-line signal is not passing through more than two or three walls.
Problem: Temperatures do not match if units are placed next to each other.
Solution: Each temperature sensor is manufactured to be accurate to within 1 degree plus or
minus and under normal conditions, so two sensors could be as much as 2 degrees
different. However, the difference can be exaggerated further because the sensors
are designed for different working environments. The indoor sensor is less
responsive to ambient air currents because of the shielding effect of the display's
case. In addition, the case can act as a heat sink to absorb and store heat from
external sources (i.e. handling of the case or radiant heat). Also, the much greater
range of the outdoor temperature sensor requires a different calibration curve than
the indoor range. Error is usually greater at the extreme ends of a range, making it
harder to compare different ranges with different curves. Under non-laboratory
conditions, it is difficult to compensate for the above factors and obtain an accurate
comparison.
MAINTENANCE AND CARE INSTRUCTIONS
Extreme temperatures, vibration, and shock should be avoided to prevent
damage to the units.
Clean displays and units with a soft, damp cloth. Do not use solvents or
scouring agents; they may mark the displays and casings.
