This wireless thermometer
uses long range 433mhz
radio frequency for
communication.
In the event that you have
reception problems due to
interference, both the main
unit and the wireless sensor
have a selectable wireless ID.
The ID switches are located
within the battery
compartments of the main
unit and the wireless sensor.
You may choose A, B or C; but
both the
main unit and the
wireless sensor ID's must match
for successful synchroniza-
tion.

Relocate the main unit and/or the wireless
sensor. Both units must be within 100 feet (30
m) from each other. Make sure both units are
placed at least 3 feet (.91 m) from other
electronic appliances and devices that may
interfere with the wireless communication (such
as TV’s, microwaves, computers etc). NOTE: It
may take up to 20 minutes for the main unit to
re-synchronize with the sensor when batteries

Rotate the wireless sensor 90º on its mounting
point. Make certain there are no large stone or
metallic surfaces disrupting the signal line-of-
sight to the state of Colorado. Make sure the
main unit and wireless sensor are placed at least
3 feet (.91 m) from other electronic appliances
and devices that may interfere with the wireless
communication (such as TV’s, microwaves,
computers etc). Large metallic surfaces will
interfere with the atomic clock signal.
