2ACGI-TX900MHH900MHz digital handheld microphone

VOLUME/CHANNEL ADJUSTMENT On OFF position, press and hold the button “B” and turn on the transmitter. Press the button “A” to scroll through the channel numbers (01-25). Press the button “B” to adjust the volume level. SAMPLING RATE SWITCH On OFF position, press and hold the button “A” and turn on the transmitter. When there is “HI” icon on the display, it means that the device sampling rate is set at 16KHz; When there is none, it means that it is set at 8KHz. Do it again to switch the sampling rate. ON/OFF Switch Button “A” Button “B” 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. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment.

FCC ID: 2ACGI-TX900MHH RF Exposure evaluation According to 447498 D01 General RF Exposure Guidance v05 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 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 Worse case is as below: Frequency (GHz) Distance (mm) Power (dBm) Power (mW) Cal. Density (mW/mm) Exclusion Threshold (mW/mm) 0.903 5 10 10.00 1.90 ≤3.0 0.915 5 10 10.00 1.91 ≤3.0 0.927 5 10 10.00 1.93 ≤3.0 Then, as a result, SAR evaluation is not required
