USAGE
Indications for Use
The Non-Contact Forehead Thermometer is an
infrared thermometer intended for the intermittent
measurement of human body temperature in people
of all ages.
Intended Operator:
At least 11 years old (5 years intensive reading
experience), no maximum.
Ambient Temperature
If there is any temperature difference between the
places where the device is stored and where it will
be used, allow the thermometer to adjust to the
room temperature where the subject is for at least
15 minutes before measurement.
Points of Attention
1. Forehead temperature is displayed in oral mode.
This mode converts the forehead temperature to
display its “oral-equivalent” value.
2. Before the measurement, the subject should stay
in a stable environment for 5 minutes and avoid
exercise or bath for 30 minutes.
3.
Keep the forehead area clean and free from sweat,
cosmetics and scars while taking the temperature.
4. The “Clinical Bias” is -2.5 to -3.1°F (-1.4 to -1.7°C).
5. The “Limits of Agreement” is 0.98.
6. The “Repeatability” is 0.36°F (0.20°C)

BEFORE WE BEGIN
This thermometer has been designed for home
use. It is not meant to replace a visit to the doctor.
Compare the measurement result to your regular
body temperature. Consult with doctor if you have
health concerns.

CARE OF YOUR PRODUCT
• The sensor lens is the most delicate part of the
thermometer and should be kept clean at all times.
Take care when cleaning the lens. Use only a
soft cloth or cotton swab with water or rubbing
alcohol. Allow the lens to dry fully for at least
1 minute before using the thermometer.
• Do not submerge any part of the thermometer in
liquids. Keep it dry and away from any liquids and
direct sunlight. Wipe clean with a damp cloth.
• Store the thermometer at room temperature
between -4 to +122°F/–20 to +50°C, RH ≤85%.
• Avoid holding the thermometer too long. This
could cause the body temperature measurement
to be lower than usual.

PRECAUTIONS
• Dispose of used batteries promptly and keep away
from children.
• Keep the thermometer and batteries away from
children.
• Do not clean the case with abrasive or corrosive
compound, which may scratch the plastic and
corrode the electronic circuits.
• Do not subject the unit to excessive force shock,
dust, temperature or humidity, which may result in
malfunction, shorter electronic life span, damaged
battery and distorted parts.
• Do not tamper with the unit’s internal components.
Doing so will invalidate the warranty on the unit
and may cause unnecessary battery damage and
distorted parts.
• Do not subject the unit to excessive exposure to
direct sunlight. The unit is not waterproof — do
not immerse it into water or expose to heavy rain.
• To avoid deformation, do not place the unit in
extreme temperatures.
• Do not use the thermometer in a microwave oven.
• Always read the user manual thoroughly
before operating.
