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 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.

remove at least one battery from each.
