Covering the forehead with hair, a cap, etc. may affect the measurement
result.
The result of the measurement is informative. If in doubt, measure the
temperature using another method.
Once the batteries have been correctly installed, the device enters
standby mode and is ready for use immediately. Briefly press the function
key (1) to initiate the measurement. The illuminated display (2) of the
device shows all its elements for about a second, after which the result of
the last measurement is displayed for another second until three
horizontal lines appear on the display. At this point, briefly pressing the M
button (4) allows you to choose between measuring the body temperature
(symbol at the top of the display) and the surface temperature of the
object (symbol ).
After selecting the temperature measurement mode, point the infrared
sensor (5) at the uncovered forehead or the selected object at a distance
of approx. 1-3 cm and briefly press the function button. The measurement
result will be displayed after about one second and a beep. For about 18
seconds after the last press of the function button, further temperature
measurements can be taken.
If no action is taken during that time the device will enter a sleep mode.
The display backlight can take on one of three colours depending on the
measurement result:

5.3 Measurement memory
While the unit is in standby, a short press of the M button (4) allows you to
view up to the last 50 measurements stored in the unit's memory.
Subsequent presses of this button display successive results in a loop. First
the result number appears briefly on the display (2), followed by the result
itself. The result with the lowest number is the most recent. If the function
button (1) is pressed or if the device is left inactive for about 18 seconds
the thermometer switches to the standby mode.
5.4 Basic settings
While the device is in standby, long press and hold the M button (4) to set
the temperature scale in which the measurements will be displayed.
Briefly press the M button to switch between Celsius and Fahrenheit.
Confirm your choice by pressing the function key (1) briefly. In the
measurement memory viewing mode, long pressing of the M button clears
the measurement memory of the instrument. While the unit is in standby,
briefly press the function key. When the display shows three horizontal
bars, a long press on the M button will switch the audible indication on and
off.
