Cautions:
● After replaced the batteries or move the thermometer to a new place ,It
is suggested to lay the forehead thermometer aside at least 30 minutes
before using, so that you can measure temperature more accurately.
● If the measurement is made without an effective distance or an
deflection of the central position of the measured object, a deflection
from actual temperature may cause. It is suggested to repeat the
measurement once or more.
● While measuring, it is suggested to focus the detection window at the
forehead, and press the measurement button in front of the handle, scan
the forehead around, so that it can measure the highest and lowest
temperature of the forehead.
● It may affect the accuracy of measurements when the forehead is
covered by hair, perspiration, cap or scarf
