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.
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.
• Make sure both the display unit and sensor are
placed out of direct sunlight and away from any heat
sources or vents (see page 5).
• Check that the batteries are installed correctly.
Batteries may need to be replaced.
