The out door sensor is not chowing up on the display unit

Thank you
We need to do the hard reset, ok?

Great!
Bring both the sensor and display unit together and remove batteries from the outdoor sensor. Make sure that the Wireless Reception Indicator on the display drops to zero bars to ensure that your display was connected to the correct sensor.

Got it
Remove the batteries and/or power adapter from the display unit.
Change the A-B-C switch on both units to a new, matching ABC channel then press and hold the reset button on the display for 20 seconds if applicable.

Great work!
Reinstall the batteries in the outdoor sensor.

Once the batteries are inserted you should see the red LED light blink approx. every 16 seconds on the front of the sensor. The red LED light should NOT stay on continuously.

Ok
Reinstall batteries and/or power cord into the display unit then immediately press and hold the reset button again for 20 seconds if applicable.

Let the units sit within a couple of feet of each other for approximately 5 minutes or until you see a solid sensor signal on the indoor display.

Great work!
Is the sensor working?

Does it appear on the display?

Great!
Then it all worked
Is there anything else I can do for you today?
