Troubleshooting
Problem Possible Solution
No outdoor sensor
reception
no bars
• Relocate the display unit and/or the 3-in-1 sensor.
The units must be within 330 ft (100 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.
• Synchronize the units:
1. Bring both the sensor and display unit indoors and
remove at least one battery from each.
2. Make sure the A-B-C switch on both units match.
3. Reinstall the battery in the outdoor sensor.
4. Reinstall battery into the display unit.
5. Let the units sit within a couple feet of each other for
about 20 minutes to gain a strong connection.
Outdoor
temperature
is ashing or
showing dashes
Flashing of the outdoor temperature may be an indication of
wireless interference:
• Make sure the A-B-C switch in the battery compartments of
both the display unit and sensor are switched to the same
letter. You may choose A, B or C; but both units must match
to sync up. Sometimes changing to a different channel
helps.
