Power on/off Power on: Short press the power button to turn on the colorimeter, after that, the indicator light will flash. Shut down: Long press the power button to turn off the colorimeter; when the mobile phone is not connected to Bluetooth, it will automatically turn off without any operation in 3 minutes; when the mobile phone is connected to Bluetooth and it will automatically turn off without any operation in 30 minutes. 2. Bluetooth connection Turn on the colorimeter, open the App and first display the logo. After the logo is displayed for 3s, enter the "Connect Device" interface and automatically start searching for Bluetooth devices. The searched devices will be displayed at the bottom of the interface. Click the device that matches the SN of the colorimeter and wait for the device to connect. After the connection is successful, it will jump to "Calibration Interface". Precautions:  If there is a Bluetooth connection error or connection failure, you can restart the App and the colorimeter, or turn off/start Bluetooth in the setting interface and then reconnect.  Click the "Browse" button, you can enter the App to view historical data without connecting to the colorimeter. 3. Calibration After the App is connected to the colorimeter, enter the "Equipment Calibration" interface. The user can perform the calibration operation or skip the calibration.  Equipment calibration After closing the bottom cap of the colorimeter, click the "Calibration" button. If the calibration is successful, the colorimeter will directly enter the measurement interface; if not, it will prompt "Calibration failed". If it prompts that the calibration failed, the possible reasons are as follows: 1. The bottom cap is not closed properly; 2. The standard tile on the bottom cap is too dirty and needs to be cleaned; 3. The attenuation of the light source leads to abnormal use, the colorimeter needs to be returned to Syntes Inc 2023-07-28 Page 5 of 15 the factory for inspection and repair.  Skip calibration The colorimeter skips the calibration operation and enters the measurement interface. When the colorimeter has not been used for a long time, it is recommended to calibrate. 4. Measurement After the App is successfully connected to the colorimeter, enter the main measurement interface. There are two measurement modes: "Color Scan" and "Color Compare". After the App is opened, the default mode is "Color Scan", there are two measurement switch buttons at the bottom of the main interface. The font of the button turns blue when selected. The current measurement mode, battery power, historical records, model and connection status are displayed on the top information bar.  Battery life Display …

Shenzhen CTB Testing Co., Ltd. FCC ID: 2BCC3-AMTRCR01 Portable device According to §15.247(e)(i) and §1.1307(b)(1), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. According to KDB447498 D01 General RF Exposure Guidance V06 The 1-g SAR and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(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 When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion.
