5.2 Head-mode
In head-mode the temperature measurement range is 0.0˚C - 100.0˚C or 32˚F - 212˚F.
After any measurement between 32˚C and < 37.6˚C or 89.6˚F and < 99.7˚F one beep
will sound and the display will light green. When the measurement is between 37.6˚C
and < 42.2˚ or 99.7˚F and <108˚F, the fever alarm will sound; 7 beeps will sound and
the display will light red. The measured temperature is shown on the display.
5.3 Out-of-range temperatures
Temperature measurements that are outside the measurement ranges will result in
error codes L˚ or H˚ on the display, accompanied by three beeps and the display
lighting red for three seconds.
“ L˚ ”: Measurement is below 32.0˚C or 89.6˚F in Head-mode or below 0.0˚C or 32˚F
in Ear-mode/ Ambient temperature mode. Please make sure you are following the
instructions on how to get accurate measurements.
“ H˚ “: Measurement is exceeding 42.2˚C or 108˚F in Head-mode or over 100.0˚C or
212˚F in Ear-mode / Ambient temperature mode. Please make sure you are following
the instructions on how to get accurate measurements.
