and turn the needle to the desired temperature using your fingers. Replace the lens cover and recheck the calibration.
DIGITAL THERMOMETER
For a digital thermometer, note how many degrees the digital display needs to be increased or decreased. Press twice directly on the mylar display towards the right center using your finger. After pressing the first time, the display should read "cal" indicating that you are in the calibration mode and after pressing the second time, the display should read either zero or a positive number or a negative number (this number is the point of origin for calibration). If your digital display needed to be increased, you
Must advance the point of origin by that many degrees by pressing directly on the mylar display towards the left top. If your digital display needed to be decreased, you must decrease the point of origin by that many degrees by pressing directly on the mylar display towards the left bottom. Once calibration is complete, return to normal temperature mode by pressing once again on the mylar display towards the right center. Now, recheck the calibration.
Example: the digital display reads 7`c and the internal thermometer reads 4`c so, the digital display must be increased by 3`. Press the right center of the display twice and the number
