Notes
Note for Forehead Temperature Measurement

• Please measure at the same point when doing forehead temperature measurement, otherwise, the temperature value will have a difference.
• In order to ensure measurement accuracy, there should no hair, sweat, cosmetics, dirt, etc on the forehead when measured.
• Cold coverage, sweating, and other cooling measures on a fever patient’s forehead will make the measurement result lower.
  Users should avoid measurements in this case.

Others

• Please keep the sensor and probe clean before and after measurement;
• The best work environment temperature is between 16℃~35℃
• Don’t use the Infrared thermometer in extreme environments, namely, the temperature is below 16℃ or over 35℃, and humidity is over 85%RH.
• When the person being measured come from a place where the temperature has a big difference from the test environment, he/she should stay in the test environment for at least 5 minutes in order to keep the balance of the body temperature. Otherwise, the measurement result will be influenced.
• If the product is taken from a place where the temperature has a big difference from the test environment, then the product should be placed in the test environment for 20  minutes before measurement.
• Please keep the surrounding environment stable. Don’t measure in the fan, air conditioning vent airflow circle.
• Please avoid using the thermometer under direct sunlight, even outdoors.
• Measurement time interval in the 20s.
• Advise measuring a few minutes later after waking up.
• Do not measure after swimming or bathing or for other reasons not yet completely dry.
• Please do not measure temperature after exercising, bathing, or meal within 30 minutes,
• Before measuring body temperature, do not make any diet, and do not engage in sports activities.
• Do not measure the baby’s temperature during or after breastfeeding.
• The thermometer can take away from the temperature measurement sites, only after the end of the voice prompts to hear the temperature.

Recommendations made three measurements in the following three cases, then take the higher value as the measurement results.

1. Children under three with weakened immune systems (in particular, to judge by children or without fever thermometer);
2. Not yet fully familiar with the use of a thermometer, so each measured temperature value may not be the same;
3. When suspecting the measurement value is low.
