Setting modification: setting parameters can be modified. Temperature measurement conversion: multiple temperature measurement modes can be switched. Test distance: 1cm ~ 15cm. Make law The correct method is the key to test accuracy, otherwise it may cause measurement error. because The requirements of infrared temperature measurement for the surrounding environment are relatively high. Therefore, please follow the following instructions. 1. Install the battery or plug in the USB to start the machine automatically. After the display screen is fully displayed for one second, the host enters the state to be tested. When there is no object within the measurement range, it enters the standby state (automatically shut down after 30s). 2. When measuring the object temperature, when the object enters the product measurement range (15cm), the product turns on the automatic measurement. To ensure the accuracy of the measurement data, please keep the measured object still. 3. In the power on state, press the left key briefly to start a manual measurement, press the right key briefly to check the temperature measurement history, and press the left and right keys simultaneously to confirm the selection. 4. In the power on state, after connecting Bluetooth, you can check the temperature measurement data and working state of the product at any time, so as to facilitate the statistical record of the temperature measurement (for details, please see the app operation instructions). 5. When the temperature difference between the object to be 5 measured and the measured ambient temperature is lower than that of the ground to be measured, the test shall be carried out less frequently Stay in the environment for more than 5 minutes, and measure it after it is caused by the ambient temperature, otherwise it will affect the measurement result. 6. When the product is taken out from the place where the temperature difference between the product and the environment to be tested is , the product shall be placed under the environment for three minutes and then be . 7. The surrounding environment of the tested air conditioner shall be stable, and it is not allowed to test in the place where the flow of fan and air conditioner is lower than that of air conditioner. 8. Do not use the product in direct sunlight. 9. During the measurement, it is recommended to measure about 3 times each time, subject to the most significant group of data. Setting adjustment This product can modify the default setting parameters. I have done it for different sales markets before I went out It is recommended not to modify the default value of the output setting. If you need to modify it, please follow the steps below 1. In the power on state, press and hold the left key to enter the user menu, press and hold the left key again to successively enter F1 to set the buzzer switch, F2 to set the alarm temperature, F3 to set the temperature deviation correction, F4 to switch between Fahrenheit and Celsius. 2. Buzzer switch setting − F1 setting method Enter F1 buzzer switch setting mode, display "on" and horn symbol or "off" and no horn symbol on screen, press left or right key to set buzzer switch, display "on" and "off" on screen. 3. Alarm temperature setting − F2 setting method Enter F2 alarm temperature setting mode, the screen displays the preset alarm temperature, press the left or right key to increase or decrease 0.1 °C to set the customized alarm temperature. 4. Temperature correction setting − F3 setting method Enter F3 temperature correction mode to adjust the measurement deviation of the product. 1 degree. (tested before delivery, it is not recommended to change this setting) 6 5. Fahre…

RF Exposure Requirements Product Description: Smart Temperature Box Model No.: AFU-THY-0004 FCC ID: 2AWTJ-AFU-THY-0004 According to the KDB 447498 D01 v06 section 4.3.1, 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 calculation17 - The result is rounded to one decimal place for comparison Calculation Result: Tx frequency range: 2402-2480MHz Min. test separation distance: 5mm Maximum Conducted Output Power: -4.68dBm Tune-Up output power: -4dBm RF channel transmit frequency: 2402MHz Result: 0.1 Limit: 3.0 The exclusion thresholds is 0.1 < 3, so the transmitter complies with the RF exposure requirements and the SAR is not required.
