You must remove the batteries in the base unit, replace them, and it should work properly. You can press the Tx button on the back of the remote unit to verify the RF reception. To ensure it is working properly, place both units next to each other indoors and make sure they read the same temperature.
The manual can be found here. Refer to page 3 for more information.

TIME ZONE SELECTION

Press SET" button on the front of home receiver to select from the following

time zones in the U.S. (zone is displayed in the upper right hand corner of

After inserting the batteries, DO NOT set the time until the OUTSIDE temperature registers. That's the trick.
