Solution: Replace batteries
Problem: No outdoor temperature is displayed.
Solution:
1. Remove all batteries, reinsert into remote rain sensor first, then into the remote
temperature sensor and then into the indoor temperature station.
2. Place remote temperature sensor closer to the indoor weather station.
3. Be sure all batteries are fresh.
4. Place remote temperature sensor and indoor weather station in a 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.
Problem: “OFL” appears in LCD.
Solution: Follow Reset directions (total rainfall accumulation has exceeded 999.99in.).
Problem: “---” Appears in the LCD (indoor weather display has lost signal from remote rain
sensor).
Solution:
1. Follow reset directions and restart the units.
2. Ensure the distance the indoor weather display remote rain sensor is at least 6 feet
(2m) away from interfering sources on a 433 MHz signal such as computers, TV
sets, headphones, speakers, etc.
3. Move indoor weather display away from metal window frames.
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.
