Problem Possible Solution

No outdoor sensor reception

If the wireless signal indicator shows no bars:

  • Relocate the display and/or the outdoor sensor. The units mus be within 165ft (500m) of each other.
  • Make sure both units are placed at least 3 feet (.9m) away from electronics that may interfere with the wireless communication (such as TVs, microwaves, computers,etc.)
  • Use standard alkaline batteries (or lithium batteries in the sensor when temperature is below 4ºF/-20ºC). Do not use heavy-duty or rechargeable batteries. NOTE: It may take a few minutes for display and sensor to synchronize after batteries are replaced.
  • Outdoor temperature is flashing or showing dashes

    Flashing of the outdoor temperature is generally an indication of wireless interference.
    1. Bring both the sensor and display indoors, side by side and remove power adapter/batteries from each.
    2. Reinstall batteries in the outdoor sensor
    3. Reinstall adapter/batteries in the indoor display.
    4. Let the units sit within a couple feet of each other for a few minutes to gain a strong connection.

    Inaccurate temperature

    Make sure that both the display unit and sensor are placed out of direct sunlight and away from any heat sources or vents.

    Display screen not working

    Check that the power adapter is plugged into the display and an electrical outlet.
