I just put new batteries into my new 00611A3 wireless indoor/outdoor thermometer, and only part of the display is showing. When I pick up the display unit, or squeeze it even the slightest amount from front to back at the upper right corner, the display shows the entire number as it should.
We are sorry to hear that the thermometer is giving you trouble. Please let us know what kind of batteries you are using in the display. We typically recommend a standard alkaline battery such as Energizer or Rayovac. Removing and reinstalling the batteries will reset the display and should help to correct any issues.
I am having continual issues with my 00611A3 thermometer. I am using only new, high quality Energizer batteries but have to replace them every 2 weeks. I need a solution or I will have to scrap it and look for another brand.
