Section 3 - Temperature Information

Question 1   "OFL" appears in the indoor temperature section of the LCD

Move the clock to an area with warmer or cooler surrounding temperature. Current surrounding temperatures are outside measuring range.

Question 2   "--.-" appears in the outdoor temperature section of the LCD
  1. Remove the batteries of both units for one minute, then reinsert them again. Make sure the batteries are new and fresh.
  2. Move the radio controlled clock closer to the sensor or place the sensor closer to the clock. Make sure the clock is at a receivable range from the sensor.
  3. Move the units to another location. Interferences from other electrical devices operating on the same signal frequency (433MHz) may prevent correct signal transmission and reception.
Question 1   "OFL" appears in the outdoor temperature section of the LCD

Wait until the current surrounding temperature cools down or increases. Current temperature is outside of the measuring range of the sensor. The outdoor temperature will be displayed again once the current surrounding temperature is within the range of the sensor.
