Acurite Wireless Thermometer, not dead yet

I own an acurite wireless thermometer that I purchased at Home Depot for around $16. It's worked flawlessly for a couple of years and mainly helps me figure out how to dress for my 4:30 am bike rides. I confess it's also been the cause of more than a few blown off rides, but I digress.

I learned that when the battery in the outdoor wireless sending unit fails, you can't just replace the 2 AA's. The indoor display and the outdoor sender will lose synchronization if you just replace the sensor batteries.

The proper battery replacement procedure is to remove the batteries from both display and sensor. Then put fresh batteries in the sensor. Next, within six minutes, put fresh batteries in the display unit. They should magically pair up immediately. If they don't, make sure both components are within 100 feet and repeat the battery replacement procedure. Good luck!
