This non-contact digital forehead thermometer is intended for the intermittent measurement of 

human body temperature in people of all ages.

OPERATING INSTRUCTIONS FOR FOREHEAD USE 

Press      to turn on the instrument. Hold the 

instrument within 4 cm from the centre of the forehead and press and hold ‘Start’ until you hear one 

beep (unless muted) to indicate the reading is complete. Readings should take approximately one 

second. The instrument will automatically turn off after 60 seconds. Manually turn the instrument 

off by pressing and holding the      for five seconds.
The temperature displayed is the “oral equivalent” value. If the temperature is above 37.5 °C 

 

(99.5 °F) you will hear three short beeps followed by one long beep. 

     FOR BEST RESULTS 

Keep the forehead area clean. Keep away from sweat, cosmetics, and scars 

while taking measurements. Please remain in a stable environment for five minutes, and avoid 

exercising, bathing, or showering for 30 minutes, which can artificially raise your temperature.

STORAGE & CLEANING- 

The instrument should be stored at room temperature, away from 

liquids and direct sunlight. If there are any temperature differences between the place where 

the instrument is stored and where you are going to measure, please allow the instrument to 

stabilize to the ambient temperature for at least 15 minutes. Holding the instrument too long 

may cause a higher ambient temperature reading. This could make the body temperature 

measurement lower than usual.
The sensor lens is the most delicate part of the instrument and should be kept clean at all times. 

Care should be taken when cleaning the lens to avoid damage. Use only a soft cloth or cotton 

swab with medical alcohol, allowing the lens to dry fully before using the instrument again.
