If a section on your multi-sensor display is not receiving a signal from the sensor, or the temperature is flashing, showing dashes, or is not updating, the unit may be experiencing wireless interference. Perform a hard reset to gain a strong connection between the units. 

Important! If you have multiple sensors:

- If you are pairing more than one temperature sensor with the display, the A-B-C switch positions must differ between each sensor. Verify that each sensor has a different channel selected by checking the switch position in the battery compartment.

1. Bring both the sensor and display together and position them side by side. NOTE: If you have multiple sensors connected to the Multi-Sensor Digital Thermometer, and you are not sure which sensor is experiencing interference, bring all sensors together with the display.
2. Remove all batteries from the sensor (or sensors).
3. Remove all batteries from the display.
4.  Wait 1 minute to ensure that any remaining battery power has discharged from both units.
5. Reinstall batteries in the outdoor sensor (or sensors) first.
6. Reinstall batteries in the display last.
7. Let units sit within a couple of feet of each other for a few minutes to ensure a wireless signal is received. *The display should receive the signal within several minutes.
8. After a connection has been established, you may place the sensor (or sensors) in their intended locations.

*If the signal connection fails after the units are separated, try a new location for the display, the sensor, or both.
