Correct application methods
The patient is an intended operator and can perform the
maintenance of the equipment.
Preventive inspections:
1.Measure and check the functions of each component to ensure
good condition of the Forehead Thermometer.
2.Check to make sure the batteries have enough power.
3.The packaged product can be transported via common vehicles.
However, it is necessary to prevent the product from rain, damp,
extrusion and mechanical collision.
Unpacking:
Open the box, take out the Forehead Thermometer and
accessories.
Battery installation or replacement:
1.Open the battery cover and replace the batteries. Properly install
the positive and negative poles of the battery.
2.Please use disposable batteries instead of rechargeable
batteries, especially using the alkaline dry batteries.
3.Remove the batteries when they become weak or when the unit
is not in use for extended periods. This will prevent damage to
the unit from battery leakage at such times
4.Do not use expired batteries for this device.
Prompt:
The emissivities of various materials may be different. Please refer
to the material emissivity. The default emissivity of this product is
1.0. The measured temperature will deviate from the actual value
for different emissivities.
Precautions
1.When opening the battery cover to replace the batteries, pay
attention to the positive and negative poles. Dying batteries should
be removed immediately. Incorrect installation will cause damage
to the product.
2.In long period storage, please remove the batteries to prevent
damage to the thermometer by fluid leakage.
3.Do not use the product in case of battery leakage or mold.
4.Do not take the battery close to the fire or put it into fire to avoid
battery explosion.
5.Do not store the battery in a high-temperature or high-humidity
environment.
6.To avoid short circuit, do not place the battery together with
metal objects such as coins or keys in the same pocket or other
containers that may cause battery short circuit.
7.In case of exposure of eyes to the electrolyte in the battery by
mistake, rinse immediately with plenty of water. In case of any haz-
ard causing injuries such as blindness, go to the nearest hospital
for medical treatment immediately.
8.In case of exposure of skin or clothes to the electrolyte in the bat-
tery by mistake, rinse immediately with plenty of water, otherwise it
may damage the skin.
The device uses D.C. 3 V 2 AAA alkaline dry batteries. When the
display shows “”, it indicates low battery and the
batteries should be replaced as soon as possible to ensure
measurement accuracy. Please dispose of the replaced
components (e.g. dry batteries) and the device when reaching to
the end of service life according to the local laws and regulations.

Precautions
1.The product is an infrared forehead thermometer for professional
measurement of body temperature. The measured temperature
will vary depending on the skin of human body.
2.When the measured object and the forehead thermometer
are not in the same environment, place the infrared forehead
thermometer in the same environment with the measured object
for 30 min prior to use.
3.The environment around the measured object should be stable.
Do not make measurement at places with large airflow such as
air outlet of fan and air conditioner, etc.
4.Do not use the device outdoors or under strong sunlight.
5.Do not hold the front end of thermometer while measuring.
6.The measurement site cannot be covered by hair. In case of
any sweat stain, wipe clean with a dry towel before measuring.
