Troubleshooting
Problem: No reception of WWVB time signal.
Solution: • Wait overnight for signal
• Be sure indoor thermo station is at least 1.8m (6 feet) from any electrical devices, such as televisions, computers, or other radio-controlled clocks.
• Remove batteries or unplug the adaptor for five minutes, reinsert and leave the unit alone overnight without pressing any buttons.
• If there are still problems, contact Discovery Channel.
Problem: Hour is incorrect (minute and date are correct).
Solution: • Be sure correct time zone and daylight savings time settings are selected.
Problem: The LCD is faint.
Solution: • Replace the batteries.
Problem: No outdoor temperature is displayed.
Solution: • Remove all batteries or unplug the adaptor, reinsert into remote temperature sensor first, then into the indoor thermo station.
• Place remote temperature sensor closer to the indoor thermo station.
• Be sure all batteries are fresh.
• Place remote temperature sensor and indoor thermo station in position so that 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 different calibration curve than the outdoor 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.
