Troubleshooting
Problem Possible Solution

Time changes or is off
by an hour or more

• Check to make sure you have selected the correct time zone. 
• Make sure you are using good quality, alkaline batteries. DO NOT use rechargeable or heavy duty batteries.
• This unit it atomic and should automatically correct itself with the date and time once it picks up the atomic signal. Try moving the unit to a window facing Colorado overnight (signal is better at night) so it can gain a strong connection. If it continues to change, you may want to relocate the unit to a different location in your home.

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.

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.
