Operation Manual Step 2: Insert the simultaneous screen successfully paired into PC computer. If the computer is connected with the simultaneous screen for the first time, it is required to double-click the "Client.exe or Client.app" application in the USB flash drive, the system will pop up the following interface automatically (if the simultaneous screen is not used for the first time, after waiting for 15 seconds, the system will automatically pop up the following interface): Step 3: after the simultaneous screen is paired with PC, the following interface shall appear. Please click the middle button in the simultaneous screen to achieve display on the same screen. Note: While the simultaneous screen is used for display on the same screen, it is required to guarantee that the hot spot of the conference tablet PC is on. Method 1: Use the Type-c interface for screen casting Step 1: Insert the peer into the Type-C interface of the meeting tablet and wait until the pairing succeeds. Step 2: Insert the matching device into the type-C interface of the computer. After the indicator light is steady on, it indicates that the connection is successful. Then press the button to start screen casting. Method 2: Use the USB interface for screen casting Step 1: Insert the simultaneous screen into USB interface of tablet PC for conference and wait for successful pairing.

Report No.: CTB230320018RF Report Tel: 4008-707-283 Web: http://www.ctb-lab.net Page 48 of 93 e) Sweep = auto couple. f) Allow the trace to stabilize. g) Measure the maximum width of the emission that is constrained by the frequencies associated with the two outermost amplitude points (upper and lower frequencies) that are attenuated by 6 dB relative to the maximum level measured in the fundamental emission. Note: The automatic bandwidth measurement capability of a spectrum analyzer or EMI receiver may be employed if it implements the functionality described in this section. For devices that use channel aggregation refer to III.A and III.C for determining emission bandwidth. D. 99% Occupied Bandwidth The 99% occupied bandwidth is the frequency bandwidth such that, below its lower and above its upper frequency limits, the mean powers are each equal to 0.5% of the total mean power of the given emission. Measurement of the 99% occupied bandwidth is required only as a condition for using the optional band-edge measurement techniques described in II.G.3.d). Measurements of 99% occupied bandwidth may also optionally be used in lieu of the EBW to define the minimum frequency range over which the 789033 D02 General UNII Test Procedures New Rules v02r01 Page 4 spectrum is integrated when measuring maximum conducted output power as described in II.E. However, the EBW must be measured to determine bandwidth dependent limits on maximum conducted output power in accordance with Section 15.407(a). The following procedure shall be used for measuring (99%) power bandwidth: 1. Set center frequency to the nominal EUT channel center frequency. 2. Set span = 1.5 times to 5.0 times the OBW. 3. Set RBW = 1% to 5% of the OBW 4. Set VBW ≥ 3 * RBW 5. Video averaging is not permitted. Where practical, a sample detection and single sweep mode shall be used. Otherwise, peak detection and max hold mode (until the trace stabilizes) shall be used. 6. Use the 99% power bandwidth function of the instrument (if available). 7. If the instrument does not have a 99% power bandwidth function, the trace data points are recovered and directly summed in power units. The recovered amplitude data points, beginning at the lowest frequency, are placed in a running sum until 0.5% of the total is reached; that frequency is recorded as the lower frequency. The process is repeated until 99.5% of the total is reached; that frequency is recorded as the upper frequency. The 99% occupied bandwidth is the difference between these two frequencies.
