FCC ID: BEJ9QK-DWAM82DB No. FCC requirements 1 Have its own RF shielding RF Block shielded by Metal Case 2 Have buffered modulation/data inputs (if such inputs are provided), Yes, the module has buffered data input. 3 The modular transmitter must have its own power supply regulation. We used self own power supply regulation. 4 Meet the antenna requirements of section 15.203 This module uses PCB pattern antenna. This module meets the antenna requirements of section 15.203 5 Be tested in a stand-alone configuration, i.e., the antenna, AC or DC power and data input/output lines must be connected to the module but, the module must not be inside another case during testing Yes, the EUT (module) was tested a stand alone configuration. 6 Be labeled with its own FCC ID number, and if the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. The proposed FCC ID label format is to be placed on the module. If FCC ID label is not visible when module is install into the system, “Contains FCC ID: BEJ9QK-DWAM82DB” shall be placed on the outside of final product. 7 The modular transmitter is manufactured so that the user can not influence the operation of the transmitter that will operate outside of the scope of the regulations. It complies with specific rules or operating requirements. And instruction is included User manual. 8 Address compliance with the Commission`s RF exposure limits in Sections 1.1310 and 2.1093. In addition, spread spectrum transmitters operation under Section 15.247 are required to address RF exposure compliance in accordance with Section 15.247(b)(4) This device will be OEM controlled installed in mobile RF exposure conditions with a minimum 20cm separation.

MAXIMUM PERMISSIBLE EXPOSURE FCC RULES §1.1310 The criteria listed in Table 1 shall be used to evaluate the environmental impact of human exposure to radio-frequency (RF) radiation as specified in §1.1307(b), except in the case of portable devices which shall be evaluated according to the provisions of §2.1093 of this chapter. CALCULATIONS Given E = √ (30 * P * G) / d and S = E ^ 2 / 3770 where E = Field Strength in Volts/meter P = Power in Watts G = Numeric antenna gain d = Distance in meters S = Power Density in milliwatts/square centimeter Combining equations, rearranging the terms to express the distance as a function of the remaining variables, changing to units of Power to mW and Distance to cm, and substituting the logarithmic form of power and gain yields: d = 0.282 * 10 ^ ((P + G) / 20) / √ S where d = MPE distance in cm P = Power in dBm G = Antenna Gain in dBi S = Power Density Limit in mW/cm^2 Rearranging terms to calculate the power density at a specific distance yields S = 0.0795 * 10 ^ ((P + G) / 10) / (d^2) The power density in units of mW/cm^2 is converted to units of W/m^2 by multiplying by a factor of 10. LIMITS From FCC §1.1310 Table 1 (B), the maximum value of S = 1.0 mW/cm^2 RESULTS (MPE distance equals 20 cm) NOTE: For mobile or fixed location transmitters, the minimum separation distance is 20 cm, even if calculations indicate that the MPE distance would be less.

After the trace being stable, Use the marker-to-peak function to set the marker to the peak of the emission. Use the marker-delta function to measure 6dB down one side of the emission. Reset the marker-delta function, and move the marker to the other side of the emission, until it is (as close as possible to) even with the reference marker level. The marker-delta reading at this point is the 6 dB bandwidth of the emission. The spectrum analyzer is set to: Center frequency = the highest, middle and the lowest Frequencies Span = 50 MHz (Greater than EBW) RBW = 100 kHz Sweep = auto VBW = ≥ RBW Detector function = peak Trace = max hold - Measurement Data: Comply Test Mode Frequency Test Results (MHz) Antenna A Lowest 9.455 Middle 9.856 Highest 9.776 Antenna B Lowest 9.535 Middle 9.375 Highest 9.455 Note 1: See next pages for actual measured spectrum plots. - Minimum Standard: The minimum 6 dB bandwidth shall be at least 500 kHz 1011-01170 DRTFCC1012-0338 TRF-RF-201(02)100714 Page 7 / 49 Copyright ○ C 2010, Digital EMC Co., Ltd. 6 dB Bandwidth Test Mode: Antenna A & Lowest Frequency 6 dB Bandwidth Test Mode: Antenna A & Middle Frequency 1011-01170 DRTFCC1012-0338 TRF-RF-201(02)100714 Page 8 / 49 Copyright ○ C 2010, Digital EMC Co., Ltd. 6 dB Bandwidth Test Mode: Antenna A & Highest Frequency 1011-01170 DRTFCC101…
