I purchased my Model 00754WB unit December 1, 2016 at Walmart.  It was working good until recently.

I noticed the outdoor temperature was staying at 42 degrees for a few days in a row.  I normally only look at the unit once or twice a day, and unfortunately spring is slow to arrive.

Yesterday the temperatures finally got into the 60's for several hours and the display still showed 42.  The outdoor unit was still flashing.  It is mounted under a protected area of a deck.

I took the unit indoors and tested both the lithium batteries and they were only 20% power.  The indor unit alkaline batteries were also bad.  Therefore I read the manual, and replaced with new batteries in the order described.  The indoor has three new Duracell alkaline, and the outdoor has two Eveready Lithium batteries.  The setting for both units was "C".

The indoor unit will only display time and indoor temperature. Outdoor shows only two dashes.  I left the units next to each other overnight, with same result.

Then I tried setting both units to "A" with same result, then tried setting both to "B".  Nothing has helped the indoor unit "find" the outdoor unit.  I also tried the reset procedure with a paperclip on the display unit.

What can be done to get the unit working?  I really miss having the outdoor temperature working.
