Query: Outdoor temp. stopped working

I bought this for my husband's birthday, 12/31. He started using it then and only 1 month later, the outdoor temp. feature does not work. The sensor still displays the outdoor temperature, but it doesn't transmit it to the main display. We will be sending this back but I don't have much hope. Too bad as it is an extremely handy device.
