NXT-101s Smart Meat Thermometer User Manual Thank you for purchasing our product. This manual addresses the safety guidelines and operating instructions. Please review this manual thoroughly before operating your device. Operation Guide Power on/off Short press the Power/Set button to turn on the device. Long press the Power/Set button to shut down. Connect the probe to the device Plug the connector of the probe into the probe jack off the device. And the screen will display the current temperature of the probe. Switch the measurement unit（°C/°F） Just press the button 5 times quickly to switch the temperature unit of the device, or you can switch the temperature unit through the mobile app control. Notes: 1. When the measured temperature reaches the alert value you set, the temperature alarm will start beeping and the value display will keep flashing. Press button one the device to stop the beeping. 2. The temperature alarm is on by default. You can turn off the temperature alarm by APP. Using App App Installation You can use the device with “Great BBQ” APP, please download it from the APP store or Google Play store. You can scan the QR code here: (Or search for "Great BBQ") Android iPhone Pair the Device with Your Phone ⚫ Press the Power/Set button to turn on the device. ⚫ Enable the Bluetooth of your smartphone. ⚫ Turn on the “Great BBQ” App on your phone. ⚫ Follow the App prompts to pair devices. Notes ⚫ When the device has a pairing record with the app, turn on the device and open the app on the phone, the device will reconnect to your phone. ⚫ If you still fail to pair the device with your phone, please kill the App process and reopen the App for pairing. And disconnect the Bluetooth connection between the mobile phone and other devices. ⚫ The App is only compatible with smartphones (Android or iPhone), not tablets or PCs. Using Tips ⚫ Before using the device, clean the probe with a soapy sponge or cloth, the rinse and dry it. ⚫ Always take your reading in the thickest part of the meat. Thin parts of the meat are difficult to measure because they tend to cook fast. Avoid touching the bone. If the tip touches the bone or heavy fat of the meat or the probe tip is not inserted deep enough, take a second reading to ensure accuracy. ⚫ When measuring different foods or meats, it may be desirable to cool the probe first by rinsing the tip with cold water. ⚫ It is recommended that you wipe the probe tip between readings. This is especially important when taking temperature readings form different foods or meat. ⚫ After using the device, turn it off to reduce unnecessary power consumption. Warnings ⚫ Do not put the device in the oven while cooking. Do not leave the probe in extremely hot foods or liquids(anything over 572°F/300°C)for more than one minute. ⚫ Always wear heat=resistant gloves to use the probes. Do not touch the probe or wire with bare hands during or right after measuring temperature since it may be very hot. ⚫ Do not use this device in a microwave oven. ⚫ Do not place this device in a place where the temperature is too high. Please operate the device within the ambient temperature range of 32°F to 122°F (0°C to 50°C). ⚫ Do not place the probe in the dishwasher or completely immerse it in any liquid. For cleaning, please wipe the probe tip with a damp soapy cloth or sponge and dry it. ⚫ Do not use the device in the rain. The thermometer is not waterproof. ⚫ Keep the probes and wires away from children. ⚫ This device is not intended for use by person under the age of 12. ⚫ If this device is not in use for a long period of time, please remove its battery.

Standalone SAR test exclusion considerations Unless specifically required by the published RF exposure KDB procedures, standalone 1-g head or body and 10-g extremity SAR evaluation for general population exposure conditions, by measurement or numerical simulation, is not required when the corresponding SAR Test Exclusion Threshold condition(s), listed below, is (are) satisfied. These test exclusion conditions are based on source-based time-averaged maximum conducted output power of the RF channel requiring evaluation, adjusted for tune-up tolerance, and the minimum test separation distance required for the exposure conditions. The minimum test separation distance defined in 4.1 f) is determined by the smallest distance from the antenna and radiating structures or outer surface of the device, according to the host form factor, exposure conditions and platform requirements, to any part of the body or extremity of a user or bystander. To qualify for SAR test exclusion, the test separation distances applied must be fully explained and justified, typically in the SAR measurement or SAR analysis report, by the operating configurations and exposure conditions of the transmitter and applicable host platform requirements, according to the required published RF exposure KDB procedures. When no other RF exposure testing or reporting are required, a statement of justification and compliance must be included in the equipment approval, in lieu of the SAR report, to qualify for SAR test exclusion. When required, the device specific conditions described in the other published RF exposure KDB procedures must be satisfied before applying these SAR test exclusion provisions. a) For 100 MHz to 6 GHz and test separation distances ≤ 50 mm, the 1-g and 10-g SAR test exclusion thresholds are determined by the following: [(max. power of channel, including tune-up tolerance, mW) / (min. test separation distance, mm)] · [√f(GHz)] ≤ 3.0 for 1-g SAR, and ≤ 7.5 for 10-g extremity SAR, where  f (GHz) is the RF channel transmit frequency in GHz  Power and distance are rounded to the nearest mW and mm before calculation  The result is rounded to one decimal place for comparison  The values 3.0 and 7.5 are referred to as numeric thresholds in step b) below The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm, and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm according to 4.1 f) is applied to determine SAR test exclusion. b) For 100 MHz to 6 GHz and test separation distances > 50 mm, the 1-g and 10-g SAR test exclusion thresholds are determined by the following (also illustrated in Appendix B): 1) {[Power allowed at numeric threshold for 50 mm in step a)] + [(test separation distance – 50 mm)·(f(MHz)/150)]} mW, for 100 MH…
