Inserting and replacing batteries
1)Remove battery cover.
2)Remove old batteries.
3)Insert 2 AAA batteries, taking care to align polarities properly.
4)Replace battery cover.
Until a measurement is taken, the thermometer will display a default temperature of “00” after battery power is restored. When the low battery symbol appears on the display the battery should be replaced. When the low battery symbol appears with the “Lo” symbol, the battery must be replaced in order for the ear thermometer to function (fig 4).

Changing Temperature Scale Between Celsius and Fahrenheit When unit is turned on press and hold the MEM and MODE buttons for 3 seconds. When scale is changed, the thermometer will beep once and the °C or °F will appear on the screen.
Using Night Mode
Night mode is a unique feature that allows a temperature reading to be taken in the dark. Night mode activates an LED flashlight to aid in aiming the thermometer at the subject’s forehead and a display that illuminates to enable you to view readings in the dark. Additionally, audio “beeps” are disabled in Night Mode.
To turn night mode on/off:
When unit is on, press the 
button. The Night Mode symbol 
will appear on the screen. To turn Night Mode off, press the 
button. The feature will be turned off and the Night Mode symbol will no longer appear on the display.
Night Mode is not recommended for general use in order to preserve battery life. Modes can be changed at any time before or after measurement. Do not change modes during measurement as the accuracy of the reading may be affected.
Changing measurement mode from PERSON to OBJECT: For measuring the temperature of a person, the thermometer must be in PERSON mode. Press and release the MODE button until you see the word “PERSON” on the display. If you would like to measure an object, press and release the MODE button until you see the word “OBJECT” on the display.
