The thermometer/temp reader used to be very accurate, but now seems to be showing a high temperature compared to what the actual room temperature is. Is there a way to re-set it or recalibrate the thermometer?

@camillelynn I read through the manual. There is no reset option or reset button. What I can suggest is completely disconnecting the battery and wait a few minutes and reconnect the battery. Maybe whatever miscalibration will reset in this manner. They have a dedicated help line at info@infantoptics.com which may be able to let you know if this is a hard ware defect or simply a reset fix.

I have a different issue.the temperature moves up and down from the top to rhe botton.After that, stops and shows a doble H H and the celsius or farenheit symbol . Any suggestion? Thanks
