ProblemPossible Solution
is flashing or
showing dashes

Flashing of the outdoor temperature is generally an indication of wireless interference.
1. Bring both the sensor and display unit indoors and remove at least one battery from each.
2. Reinstall the battery in the outdoor sensor.

3. Reinstall the battery in the display unit.
4. Let the units sit within a couple feet of each other for about 20 minutes to gain a strong connection.

Select degrees
Fahrenheit or Celsius

To select between degrees Fahrenheit (ºF) or Celsius (ºC) temperature units, press the ºC/ºF button located inside the battery compartment of the display.

No outdoor 

If the wireless signal indicator shows no bars:
• Relocate the display unit and/or the outdoor sensor. The units must be within 165 ft (50 m) of each other.
• Make sure both units are placed at least 3 feet (.9 m) away from electronics that may interfere with the wireless communication (such as TVs, microwaves, computers, etc).  
• Use standard alkaline batteries (or lithium batteries in sensor when temperature is below -4ºF/-20ºC). Do not use heavy duty or rechargeable batteries. NOTE: It may take up to 20 minutes for display unit and sensor to synchronize after batteries are replaced.
Make sure both the display unit and sensor are placed out of direct sunlight and away from any heat sources or vents.
