  1. Advises before use

Infrared forehead thermometer has higher requirement on the surrounding temperature, proper usage

is the key to accurate measurement.

(1)This product is a professional infrared forehead thermometer to measure body temperature.

The measured results vary from different human skins.

(2)If the indoor temperature changes quite a lot, you have to keep the product within the room for 20 minutes before use.

(3) If the temperature where the person comes from varies a lot from the measured temperature,

hold on in the measured environment for at least 5 minutes before measurement.

(4)Surrounding temperature of the measured person should be stable. Strong air flow positions such as outlet

of the fan and air condition will not be acceptable.

(5)Do not use this product outdoors or in areas with strong sunlight.

(6)During measurement, do not hold the front end of the measuring instrument.

(7)The measuring area should not be blocked by hair. Remove sweat with a dry towel before measurement

cooling measures, under which condition the measurement result will be lower.

(9)Comparison of different temperature measurement methods

Different results you can get by different measurement methods, specifically as below:

Measuring partNormal temperature
Anus temperature36.6 ℃~38℃
Oral temperature35.5℃ ~37.5℃
Axillary temperature34.7℃~37.3℃
Cochlear temperature35.8℃~38℃
Forehead temperature35. 8℃~37. 8℃

6.Rapid use of the product

6.1 Battery installation

6.2First time use of this product you have to get it with battery installed and then start the temperature measurement.

6.3 The front of the thermometer is aligned to the forehead (distance from 5 to 15cm) and make sure there
