1)  This machine has two functions, it can measure both ear and forehead temperature.

2)   1 second measure the temperature, easily and fast.

3)  Sensor measurement technology, high precision.

4)  Automatically power-off, if left idle for 60 seconds.

5)  One-key measurement, easy to use.

6)  Alarm for fever, better to know your body situation.

7)  Stores 12 sets recent measurement data, easy for your data contrast.

8)  Safety by infrared measuring, avoid the damage of the measuring by traditional mercury thermometer


Measuring Steps


Step 1: Inset the battery, press the Start button, all symbols appear on the display, 1 second later it appears the temperature measured last time, the sign ‘M’ appears at the same time.



Step 2: The sign “M” disappear, forehead/ear indicator appear, it meas the place you measured last time, then the temperature unit flickering, now is the measuring interface.


Step 3Direct the probe to measuring area, press the “measuring” button till a “Beep” sound from the speaker. Measuring program starts. Keeping device in position for one second after two “Beep” sounds, the temperature value will show on screen along with the model symbol.


Step 4: During next 6 seconds when test result lasting on the screen, user can no longer make a measurement until a sound of “Beep” aural reminder and a “” symbol twinkling on the screen.   


Step 5: No operation in 60 seconds, the device will record the last measuring data and shut down automatically.


Method to Measuring Ear Temperature


 Take off the forehead temperature cover. With the subject’s head upright, take hold of the outer part of the ear, gently pull back and upward to straighten the ear canal, put the probe to ear canal slowly till the body of device stay completely close to ear canal.


Method to Measuring Forehead Temperature


Do not take off the forehead temperature cover, locate the probe to midway of subject’s forehead, stay close to skin.
