Indication for Use Based on above comparison chart, both subject and predicate device indicate for use is intended for "the intermittent measurement and monitoring of human body temperature for people of all ages in the home", while subject device FR1MF1-B (NC150 BT) indicates Bluetooth function "The device can be used in connection with a smart phone running the «Microlife Connected Health +» APP. The memory data can be transferred to the smart phone via Bluetooth." Refer to the below section 6. Bluetooth function for details. As Microlife states Bluetooth® function will not affect the performance of the device as its only function is to transfer data, though indication for use is different, it does not affect subject device's performance, safety and effectiveness. ## 2. Appearance, Physical Dimension and Weight The physical dimension of the subject device FR1MF1-B (NC150 BT) is 141.1 x 43.3 x 36.9 mm, while predicate device FR1DG1 (NC200) is 156.7 x 43 x 47 mm. The weight of the subject device FR1MF1-B (NC150 BT) is 90 g (with batteries), 67 g (w/o batteries), while predicate device FR1DG1 (NC200) is 91.5 g (with batteries), 68.5 g (w/o batteries). Those differences are caused because of their different appearance, but the difference does not raise any new safety and effectiveness questions. This has been tested and confirmed according to IEC 60601-1-2 EMC Test Report, IEC 60601-1, AAMIANSI ES60601-1 Safety Test Report and MISC 003 ISO 80601-2-56 Test Report. ## 3. Error display user interface (known as UI) Both subject device FR1MF1-B (NC150 BT) and the predicate device FR1DG1 (NC200) have self-test function. And both devices perform self-test every time when it is switched on to always quarantee the specified accuracy of any measurement. When it has error, it will display error icon on LCD of the device. Subject device FR1MF1-B (NC150 BT) will display icon "Err", while predicate device FR1DG1 (NC200) will display icon "Er0", "Er6". Although the icons are different, the purposes are the same. It does not affect device's performance, safety and effectiveness. ## 4. Auto measurement The predicate device FR1DG1 (NC200) has auto measurement function, while subject device FR1MF1-B (NC150 BT) doesn't. Auto measurement is a feature that enables device to start measurement if detecting the distance is within 5cm (the appropriate measuring distance). As to the subject device FR1MF1-B (NC150 BT), in order to obtain correct measurement, the appropriate measurement distance would be the same as the predicate device which is within 5 cm. The appropriate measurement distance for the subject device. FR1MF1-B (NC150 BT), is clearly stated in Draft Instruction Manual for FR1MF1-B(NC150 BT) page 9, section 7 "Direction of use", point 4 and 5 that "Aim the thermometer perpendicularly at the center of the forehead with a distance of no more than 5 cm. Press the START button ... ". Therefore, the appropriate measuring distance is supposed to be used regardless auto or manual measurement method is carried out. That is why the measurement algorithm for the predicate device and the subject device is identical and won't affect performance or accuracy of the subject device. #### 5. Firmware version The firmware versions for the predicate device, FR1DG1 (NC200), and the subject device, FR1MF1-B (NC150BT), are PH15.0 & PH18.1 respectively. The only difference between firmware version PH15.0 and PH18.1 is auto measurement function, please refer to the above section 4.Auto measurement for details. Since the measurement algorithm itself in the predicate and subject device is identical, firmware version differences does not affect performance and accuracy. And the predicate {9}------------------------------------------------ device has been validated in accordance with ISO 80601-2-56 and ASTM 1965-98. For the details, please refer to the clinical test report, Clinical Test Report of FR1DG1 NC200. Therefore, Microlife believes another clinical test for the identical measurement algorithm used in the subject device is not required. ## 6. Bluetooth Function As Microlife states in Draft Instruction Manual for FR1MF1-B(NC150 BT) Page 12 "Notes" section. "The Bluetooth® of this thermometer is a medical device data system (MDDS) as its only function is for records and no additional functions. It does not modify the data or modify the display of the data, and it does not by itself control the functions or parameters of any other medical device. It is not active when the thermometer is recording data or during measurement. The thermometer will not sound any alarm with or without Bluetooth®. The Bluetooth® is used only to transfer data from point B. The App on your smart devices cannot be used to start or stop the thermometer, nor update the firmware of thermometer via Bluetooth®." Microlife states Bluetooth® function of subject device will not affect the clinical performance of the subject device, and provided FCC Certification (MISC 004, 001), Bluetooth RF Test Report (MISC 004, 002) and Bluetooth RF Exposure Evaluation Report (MISC 004, 003) for reference. ## 7. Materials The button material of subject device FR1MF1-B (NC150 BT) is ABS, whereas the button material of predicate device FR1DG1 (NC200) is PMMA. However, the button materials of subject device is identical to the button materials of the Microlife Non-contact Infrared Forehead thermometer FR1DZ1 as it was approved under K100953 in formulation, processing, and sterilization, and no other chemicals have been added (e.g., plasticizers, fillers, color additives, cleaning agents, mold release agents, etc.). Based upon the aforementioned information, the two devices are substantially equivalent. ## Non-Clinical Performance Testing Testing information demonstrating performance of the Microlife Non-Contact Infrared Forehead Thermometer, Model FR1MF1-B (NC150 BT) in the intended environment of use is supported by testing that was conducted in accordance with Guidance on the Content of Premarket Notification [510(K)] Submissions for Clinical Electronic Thermometers.
