Troubleshooting
No outdoor sensor
reception
no bars
If the wireless signal indicator shows no bars:
• Relocate the display unit and/or the outdoor 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.

indication of wireless interference.
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 the battery in the display unit.
5. Let the units sit within a couple feet of each other
for about 20 minutes to gain a strong connection.
