3.
Fit the probe snuggly into the ear canal, then push
and release the Start button.
4.
If the probe has been positioned securely into
the ear canal during the complete measuring
process, a long beep will signal the end of the
measuring process. The thermometer detects
that an accurate temperature measurement has
been taken. The result is shown on the display.
If you take the temperature of another person, the
«ExacTemp» light can be of help. It flashes during
the measuring process as long as the probe is
securely positioned, and lights up continuously
when the thermometer detects that an accurate
measurement has been taken.
