#### 4 Device Description
The thermometer measures the temperatures of people by detecting the energy. The external probe plays an important role in the measuring process. As soon as the thermometer is placed at the center of the forehead or the object with a distance of 15mm-50mm and the radiation sensor is activated, the measurement will be taken instantly by detection of the infrared heat.
The thermometer AET-R161 can be connected with FOND APP through Bluetooth. The FOND APP applies to mobile phones which systems are Android 4.3 and above, or IOS 8.0 and above, and can be downloaded from Google store (for Android 4.3 and above) or iPhone APP Store (for IOS 8.0 and above). The data measured with AET-R161 can be transmitted to the FOND APP, where data can be recorded, saved and shared.
The device principle of operation is described as below:
All object, solid, liquid or gas, emit energy by radiation. The intensity of this energy depends on the temperature of the object. The Infrared Thermometer is therefore able to measure the temperature of a person by the energy the person emits. This measurement can be taken by an external temperature probe on the device for analysis and register the ambient temperature. Therefore, as soon as the operator holds the thermometer near forehead and activates the radiation 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.
The thermometer includes four models: AET-R161, AET-R171, AET-R1D2, AET-R1B1. They all have the following basic functions:
- Sound alarm if the temperature exceeds 37.8℃.
- LCD back-lighted digital screen.
- Data displayed in Celsius or Fahrenheit.
- Automatic stop (energy saver).
Their detailed functions see below table:

#### Note 03:
The memory is just for storage of measurement data and viewing by users and it will not affect the performance of the subject device.
#### Note 04:
The main difference between the batteries of the Predicate and the subject device is the size, which will not affect the performance. Furthermore, the electric safety of the battery has been validated with the subject device according to the IEC 60601-1.
#### Note 05:
The difference in waterproof will not affect the performance of the subject device, which has passed IEC 60601-1 and IEC 60601-1-11 safety test.

#### 8 Brief discussion of clinical tests
The clinical performance test protocol and data analysis is conducted as the requirement of ASTM E1965-98 (2009).
In this clinical study for the clinical accuracy validation, we conduct tests with Infrared Thermometer (model: AET-R161) and the RCT (model: WDJ-001) on the presentative patient populations, which include three age groups, i.e. Infants (two months to 1 year old), Children (1 up to 5 years old) and Adults (older than 5 years), and the number of subjects is 38 for Infants, 36 for Children and 42 for Adults.
The test report showed the clinical performance of the subject device complied with the requirement of ASTM E1965-98 (2009). Therefore, the subject device is able to measure patients' temperatures as intended.
#### 9 Conclusions
Based on the above information, we conclude that the subject device, Non-contact Infrared Thermometer, is substantially equivalent to the predicate device.
