I have display unit model # 06046M which was also recently replaced by acurite due to needing to continually reset the unit (thus losing all saved data). I tried to now run the unit with NO batteries in it. The unit had been working fine and we have had no power outages. For some reason all of a sudden the low battery has shown up on the display unit causing the unit to stop displaying any data. (I have a second display unit which this has not occurred. It is working fine and displays all data). The display unit which is not displaying any information is not completely "frozen" as the time and dew point/wind chill remains on screen and changes fine. However, there is no temperature or wind speed/direction showing up. Is there a reason for this? The original display unit I got was replaced because of this issue and yet here we are again.
