• Clean the forehead from sweat, makeup, etc
• Press the
ON
button briefly. The unit now displays the symbol for forehead
mode (default mode).
• You will hear two beeps.
• Now point the measuring sensor at a suitable measuring spot in the middle
of the forehead at a distance of about 4 cm.
• Hold it steadily at this position and press the
START
button.
• A beep will sound once the measurement is completed, after approx. 1 second.
• If the reading is 37.5°C or higher, you will hear three short beeps.
• Remove the thermometer from the measuring area. Read the temperature on
the LCD display. The blue LED backlight turns on for 5 seconds.
7.2 Repeated measurements
• To repeat measurements, always return to the same point of measuring on
the forehead. Wait until the symbol for forehead mode stops flashing.
Remember:
• The forehead temperature is equivalent to oral temperature (oral temperature
is normally 0.5 °C less then rectal measured temperature.) This is based on
the average population. For some people it may be different and it is recom-
mended to learn and recognize the forehead temperature while healthy.
7.3 Memory function
• The thermometer automatically stores the last 25 temperature values in the
forehead temperature mode.
• To use the memory function, press the
ON
button while the thermometer is
turned on. The memory symbol appears. “1” appears briefly, then the tem-
perature of the last measurement.
• Each time the ON button is pressed, the temperatures of the previous mea-
surements (2 to 25) are displayed. If no more measured values are stored, - -
- appears on the display.
7.4 °C/°F selection and clearing of the memory
• When the device is switched off, press the
START
button and the
