Enter the VIA Workx APP to Connect M500, the "Camera" interface will be displayed by default, click "Settings", and find the "Optional Accessories" in the "Settings" page, and the Wireless Speed Sensor is N/A (unpaired state) when it is used for the first time. (Figure 1) Figure 1 3. If the Wireless Speed Sensor has been paired before, the optional accessory “Wireless Speed Sensor” is in paired status and displays the MAC address of the Wireless Speed Sensor. (Figure 2) Click on the “Wireless Speed Sensor” in the app settings page to unpair. (Figure 3) After VIA TECHNOLOGIES INC DOCUMENT NO.：WS200 REVISION：A PAGE NO.：PAGE 2 OF 7 unpairing, it will revert to the "unpaired" state. (Figure 1) Figure 2 Figure 3 4. When the Wireless Speed Sensor is in the "unpaired" state, click on the “Wireless Speed Sensor” to enter the Wireless Speed Sensor pairing prompt page. (Figure 4) Click "Start Pairing", wait for the M500 to scan to the corresponding Wireless Speed Sensor, (Figure 5) click on the Wireless Speed Sensor that needs to be added, Enter Maximum Speed Limit, Tire Dimension and Installation Location. (Figure 6) Click "OK" and it will be displayed in the pairing. (Figure 7) After successful pairing, you can see the MAC and corresponding battery information of the connected Wireless Speed Sensor on the settings page.

These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: —Reorient or relocate the receiving antenna. —Increase the separation between the equipment and receiver. —Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. —Consult the dealer or an experienced radio/TV technician for help. 3.This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. 4.RF exposure statements: This equipment complies with FCC RF radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20 centimeters between the radiator and your body or nearby persons.

Reference Standard and Guidance The Maximum Permissible Exposure (MPE) evaluation documented in this report were performed in accordance with following FCC published KDB guidance and standard： 47 CFR Part 1.1307 47 CFR Part 1.1310 47 CFR Part 2.1091 KDB Publication 447498 D01 – General RF Exposure Guidance v06 KDB Publication 447498 D04 – Interim General RF Exposure Guidance v01 1.2. RF Exposure Limits According to 47 CFR §1.1310, for operations within the frequency range of 300 kHz and 6 GHz (inclusive), the limits for maximum permissible exposure (MPE), derived from whole-body SAR limits and listed in below table, may be used instead of whole-body SAR limits to evaluate the environmental impact of human exposure to RF radiation as specified in §1.1307(b), except for portable devices as defined in §2.1093 of this chapter as these evaluations shall be performed according to the SAR provisions in §2.1093. At operating frequencies above 6 GHz, the MPE limits listed in below table shall be used in all cases to evaluate the environmental impact of human exposure to RF radiation as specified in §1.1307(b). Limits for Maximum Permissible Exposure (MPE) to Radiofrequency Electromagnetic Fields Frequency Range (MHz) Electric Field Strength (V/m) Magnetic Field Strength (A/m) Power Density (mW/cm2) Averaging Time (minutes) (i) Limits for Occupational / Controlled Exposure 0.3 – 3.0 614 1.63 *(100) ≤ 6 3.0 – 30 1842 / f 4.89 / f *(900 / f2) < 6 30 – 300 61.4 0.163 1.0 < 6 300 – 1500 N/A N/A f / 300 < 6 1500 – 100000 N/A N/A 5 < 6 (ii) Limits for General Population / Uncontrolled Exposure 0.3 – 1.34 614 1.63 *(100) < 30 1.34 – 30 824 / f 2.19 / f *(180 / f2) < 30 30 – 300 27.5 0.073 0.2 < 30 300 – 1500 N/A N/A f / 1500 < 30 1500 – 100000 N/A N/A 1.0 < 30 Notes: 1. f = frequency in MHz.…
