I put in new battery, how do I change from Cent. To Fahrenheit?
Hello, here are instructions on how to do this according to the manufacturer:
"Before taking temperature measurements, select either Celsius or Fahrenheit mode. When unit is off, press and hold the ‘ON/OFF’ button and the display will alternate between ‘°C’ and ‘°F’. Release the ‘ON/OFF’ button when your desired temperature mode shows in the display. To switch temperature mode, simply repeat this process."

How do I change the battery on a Comark dt300? I can turn the black circle but I can't get it off.
Hello, according to the manufacturer it is only about a quarter-turn to open the battery compartment, and if it will not open after that, try rapping it on the counter for the cover to pop out. Thank you!
