2A9QF-KT820Game steering wheel

1 G30-R808A方向盘 V2版本 20220718 1 R808A 1080 Degree Guided Wired Steering Wheel ● Precautions 1. What is DirectInput mode: DirectInput is the old game input standard of the Windows operating system. Most old games support game controllers to use DirectInput. If the game supports the DirectInput game controller, and the steering wheel is in XInput mode, most functions of the steering wheel will not work normally, nor will it support the vibration function. What is XInput mode: XInput mode is pc360 mode. XInput is the latest game input standard of the Windows operating system. Most recent games support game controllers to use XInput, and the XBOX360 handle uses XInput. If the game supports the XInput game controller and the steering wheel is in XInput mode, vibration feedback and all functions of the steering wheel will work normally. If the game supports the XInput game controller and the steering wheel is in DirectInput mode, the steering wheel will not work normally in the game (unless you switch the steering wheel to XInput mode). 2. When the steering wheel is powered on, the default DirectInput mode supports the H lever; If the steering wheel is in XInput mode, the H gear lever is not supported, and the H gear lever can be used normally only when the steering wheel is in DirectInput mode. 3. The gear lever and pedal cannot be inserted in the wrong position to avoid abnormal problems. 4. If the pedal or gear lever is abnormal, please check whether the USB socket in the storage box behind the steering wheel is inserted in the wrong position or whether the USB plug is inserted to the bottom. 5. If there is no vibration in the steering wheel game, please check whether the game supports vibration, and check whether the steering wheel DirectInput mode or XInput mode matches the game mode. 6. When the sensitivity is set above level 5, the function steering of 1080 degrees due to the high sensitivity will become smaller. (sensitivity is not suitable for cart games) 7. After receiving the steering wheel, please press the reset key for 5 seconds to reset the steering wheel, and then turn it left and right to the maximum angle to calibrate the direction. 8. The steering wheel has an automatic calibration function. Before power on, please put the refueling/braking/clutch/gear lever of the wheel disc/pedal in the nonopnonoperating before normal calibration. Otherwise, poor calibration will occur . ● Introduction to the steering wheel 1. Steering wheel support platform ps5 / PS4 / Xbox series X / Xbox One / Xbox 360; What is steering wheel guidance?

RF Exposure evaluation FCC ID: 2A9QF-KT820 1.1. Applicable Standard According to §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 §1.1310 and §2.1093 RF exposure requirement KDB447498 v06: Mobile and Portable Devices RF Exposure Procedures and Equipment Authorization Policies 1.2. Requirement According to KDB447498 D01 General RF Exposure Guidance v06 Section 4.3.1 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, listed below, is 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.22 The minimum test separation distance 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 (see 5) of section 4.1). To qualify for SAR test exclusion, the test separation distances applied must be fully explained and justified by the operating configurations and exposure conditions of the transmitter and applicable host platform requirements, typically in the SAR measurement or SAR analysis report, according to the required published RF exposure KDB procedures. When no other RF exposure testing or reporting is required, a statement of justification and compliance must be included in the equipment approval, in lieu of the SAR report, to qualify for the 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; for example, handheld PTT two-way radios, handsets, laptops & tablets etc.23 “ [(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 • 3.0 and 7.5 are referred to as the numeric thresholds in the step 2 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 5) in section 4.1 is applied to determine SAR test exclusion. 1.3.
