143. Place the indoor temperature station onto thescrew using the hanging hole on the backside.Gently pull the station down to lock the screwinto place.TROUBLESHOOTINGProblem: The LCD is faintSolution: Replace batteriesProblem: No outdoor temperature is displayed.Solution:1. Remove all batteries, reinsert into remote temperature sensor first, theninto the indoor temperature station.2. Place remote temperature sensor closer to the indoor temperaturestation.3. Be sure all batteries are fresh.4. Place remote temperature sensor and indoor temperature station inposition so the straight-line signal is not passing through more than twoor 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 1degree plus or minus and under normal conditions, so two sensors couldbe as much as 2 degrees different. However, the difference can beexaggerated further because the sensors are designed for differentworking environments. The indoor sensor is less responsive to ambientair currents because of the shielding effect of the display's case. Inaddition, the case can act as a heat sink to absorb and store heat fromexternal sources (i.e. handling of the case or radiant heat). Also, the muchgreater range of the outdoor temperature sensor requires a differentcalibration curve than the indoor range. Error is usually greater at theextreme ends of a range, making it harder to compare different rangeswith different curves. Under non-laboratory conditions, it is difficult tocompensate for the above factors and obtain an accurate comparison.NOTE: For problems not solved, please contact La Crosse Technology.
