INTRODUCTION
The AT2102 Infrared Non-Contact Thermometer has been developed using the latest infrared technology. This technology allows temporal artery (TA) temperature to be taken at a distance of about 3cm~5cm away from the forehead. Precise, instantaneous, and without contact, the AT2102 is, up to now, the most suitable thermometer for temperature measurement. It has been demonstrated that this method of TA temperature measurement is more precise than the tympanic thermometry and better tolerated than rectal thermometry ( 1). However, as with other types of thermometers, it is essential to use the AT2102 properly in order to obtain reliable and stable results. You are therefore advised to read this instruction manual and the safety precautions carefully before use.

PRECAUTIONS BEFORE USE
The AT2102 is pre-set at the factory. It is not necessary to calibrate the device when starting it up.
In order to obtain reliable and stable results, you are advised each time there is a significant change in the ambient temperature due to a change in environment, to allow the AT2102 to acclimatize to the new ambient temperature for 15 to 20 minutes before using it. It is important to allow a 1 minute interval between each measurement.
OPERATING PRINCIPLE
All objects, solid, liquid, or gas, emit energy by radiation. The intensity of this energy depends on the temperature of the object. The AT2102 infrared thermometer is therefore able to measure the temperature of a person by the energy the person emits. This measurement can be taken thanks to an external temperature probe on the device which analyses and registers the ambient temperature. Therefore, as soon as the operator holds the thermometer near the body and activates the infrared sensor, the measurement is taken instantly by detection of the infrared heat generated by the arterial blood flow. Body heat can therefore be measured without any interference from the heat of the surrounding environment.
NORMAL TEMPERATURES ACCORDING TO AGE
| Age | °C | °F |
| 0-2 years | 36.4-38.0 | 97.5-100.4 |
| 3-10 years | 36.1-37.8 | 97.0-100.0 |
| 11-65 years | 35.9-37.6 | 96.6-99.7 |
| > 65 years | 35.8-37.5 | 96.4-99.5 |
PRACTICAL CONSIDERATIONS WHEN TAKING A TEMPERATURE
- In order to ensure that precise and accurate temperature measurements are obtained, it is essential that each user receive adequate information on and training in the temperature measurement technique when using this device.
- It is essential to remember that although procedures such as taking a temperature may be simple, they must not be trivialized.
- Temperature should be taken in a neutral context. The patient must not have undertaken vigorous physical activity prior to taking his/her temperature and the room temperature must be moderate.
- Be aware of physiological variations in temperature which must be taken into consideration when evaluating the results: temperature increases by 0.5°C between 6 am and 3 pm. Women have a temperature that is higher, on average, by around 0.2°C. Their temperature also varies in accordance with their ovarian cycle. It rises by 0.5°C in the second half of the cycle and at the early stages of pregnancy.
- When sitting, temperature is lower by about 0.3°C to 0.4°C than when standing.
HOW TO TAKE A TEMPERATURE
- Aim at the FOREHEAD over the right temporal region from a distance of about 3cm~5cm
- Press the thermometer’s measurement button and the temperature is instantly measured and displayed.
- The reliability of the measurement cannot be guaranteed if the temperature is measured over another part of the body (e.g. arm, torso, etc.)
CONSTRAINTS
Please observe the following before any temperature measurements to ensure a stable and reliable result:
- Push back hair from the forehead
- Wipe away any perspiration from the forehead
- Avoid any drafts (e.g. from nasal cannulas, air conditioning, etc.)
- Allow a 1 minute interval between each measurement.
- Each time there is a significant change in the ambient temperature due to a change in the environment, allow the AT2102 to acclimatize to this ambient temperature for at least 15 minutes before using it.

If you have problems while using your thermometer, please refer to this guide to help resolve the problem. If the problem persists, please contact our customer service.
THE SCREEN DISPLAYS THE MESSAGE HI
When using the AT2102 Thermometer, the message “ HI” can show on the screen. In this case, the temperature is above the measurement range selected, above 42.9 °C (109.2°F) in Body Mode.
THE SCREEN DISPLAYS THE MESSAGE LO
When using the AT2102 Thermometer, the message “ LO” can show on the screen. In this case, the temperature analyzed is under the measuring range selected, less than 32°C (89.6°F) in Body Mode.
This message displays for various reasons. Please find below a list of the main issues：
| Reasons for LO message display | Advice |
| Temperature reading hampered by hair or perspiration. | Make sure there is no obstruction or dampness prior to taking temperature. |
| Temperature hampered by an air draft or dramatic change in ambient area of use | Make sure there is no air blowing in the; this could affect the infrared temperature reading. |
| Temperature readings are too close together, and the thermometer did not have time to reboot. | Pause for 15 seconds minimum between readings; a 1 minute pause is recommended. |
| The measuring distance is too far. | Take measurements at the recommended distance (app. 3~5 cm; 1.2in~2.0in). |
