12-2. LCD display "LO": The device tells you that the aim object temperature is out of the
measuring range, either below 35*C(95.0°F) in Body mode or below 0°C(32°F). 14-3.
Reasons for “HI" and "LO", and suggestions to solve:
Possible reasons
Maintenance Suggestions
Testing results affected by hair,
perspiration etc.
Make sure that there is no obstacles in
front of the forehead.
Testing results effected by floating
airflow
Make sure far away from floating airflow
The measuring distance is too far.
Make sure the measuring distance
is 1-3cm (0.4-1.2 in).
From outside to inside, or from low
ambient temperature to high ambient
temperature.
Keep the device in the new ambient for 15-
20 minutes before measuring
The measuring values are too close each
other.
Keep the device left for 15 seconds after
2 continuous measuring, one minute will be
better.

General Knowledge of Body Temperature
Human body is a very complicated comprehensive system, and the body temperature is
a very important indicator of the body health conditions. We can take the temperatures of
our forehead, ear, oral, auxiliary etc. to check our health conditions. Different temperature
will be for different body parts, please kindly check the values as following:
Measurement
Normal Temperature(°C)
Normal Temperature (°F)
Rectal
36.6 to 38
97.8 to 100.4
Oral
Oral
35.5 to 37.5
35.5 to 37.5
95.9 to 99.5
94.4 to 99.1
Auxiliary
34.7 to 37.3
94.4 to 99.1
Auricular
35.8 to 38
96.4 to 100.4
Forehead/Temporal
(Thermo Flash)
34.7 to 37.8
94.5 to 100.0
The human body temperature also varies throughout the day, it can also be influenced by
numerous external factors: age, sex, type and thickness of skin....

Women body temperature is also different from the men body temperature, usually higher
than that of men's by 0.3°C (0.5°F), moreover, the women body temperature who is under
ovulatory time is usually higher by 0.3°C(0.5°F) to 0.5 °C(0.9°F) than that of the body
temperature when she is not under ovulatory time. Basing on this knowledge, many women
take their body temperature every morning and draw out the diagraph of their base body
