2BFJU-FSUBLUETOOTH OPTICAL PROBE FOR SMART UTILITY METERS

OP-BT series simple user manual Need prepared tools: computer (with Bluetooth) or Bluetooth adapter serial porttest tool operating process: 1. OP-BT series converter: Power on-long press the power key for 3~5 seconds, the power working light is on.(Otherwise, usually press 3~5 seconds to shutdown) 2. In the case of OP-BT boot, use the computer side Bluetooth to connect with the OP-BT converter, the computer side will be a virtual slogan,with this slogan can be used to communicate with the device. Step 1: Right-click Start and select the Settings item. Step 2: Select the "Bluetooth and other devices" option and click on the "Show more devices" option. Step 3:Select the 'More Devices and Print Settings' option. Step 4:Click on the 'Add Device' option to search for devices. Step 5:Select the classic Bluetooth mode device "BT00001" and click "Next". Attention: The computer can only connect to the SPP mode of Bluetooth optical head, do not connect device names with BLE suffix. Step 6: Enter the pairing code (default 1234), and then click"Next". Step 7: Device added successfully. Step 8: Right click on the BT00001 device, select "Properties", and then click on the "Services" option to view the virtual serial port number generated by the Bluetooth device. This virtual serial port number can be used to communicate with the meter in the meter reading software. (This routine generates serial port number COM4) Other settings: Click on option 1, click on option 2 to enter the display interface, and configure option 3 as Advanced 3.Open the serial assistant tool. In the serial port assistant tool, select the virtual serialport number generated by the device, enter any data in the sending area, and then press thesend button. OP-BT can send the data out. When there is data transmission, the TX light on the OP-BT device flashes simultaneously. OP-BT can also receive external device data, and the RX light flashes simultaneously. The data will be displayed in the serial assistant display window。 Warning: Any Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.

Bay Area Compliance Laboratories Corp. (Shenzhen) Report No.: 2401T54885E-RFB TR-EM-RF009 Page 62 of 68 Version 1.0 (2023/10/07) RF EXPOSURE EVALUATION Applicable Standard According to FCC §2.1093 and §1.1307(b) (1), systems operating under the provisions of this section shall be operated in a manner that ensure that the public is not exposed to radio frequency energy level in excess of the Commission’s guideline. According to KDB 447498 D01 General RF Exposure Guidance The 1-g 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 1. f(GHz) is the RF channel transmit frequency in GHz. 2. Power and distance are rounded to the nearest mW and mm before calculation. 3. The result is rounded to one decimal place for comparison. 4. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test Exclusion. Measurement Result For worst case: Mode Frequency (MHz) Max tune-up conducted power # (dBm) Max tune-up conducted power # (mW) Distance (mm) Calculated value Threshold (1-g SAR) SAR Test Exclusion BLE 2402-2480 1.0 1.26 5 0.4 3 Yes Bluetooth 2402-2480 -3.5 0.45 5 0.14 3 Yes Note: The tune up conducted power # was provided by the applicant Result: Compliant
