I have a 01120m that the outdoor temp is wrong. I got this unit for Christmas and it is now mid April. At first the unit worked fine. For the past couple of weeks the temp does not rise above about 44 degrees F. I followed the instructions in the thread "00411 / 00609 / 00611A2 AcuRite Thermomete". Now the outdoor temp and humidity just show bars. It has been over 2 hours since I re-installed the batteries as instructed.
