The physical crystal and tuning capacitors may be located external to the shielded radio elements. The device is equipped with Metal shielding to cover RF section. Refer to external photos Y 2 The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with Part 15 requirements under conditions of excessive data rates or over- modulation. All inputs to the device are buffered through logic U1 inputs. Refer to Schematic Diagram. Y 3 The modular transmitter must have its own power supply regulation. The device is equipped with Internal 1.8 V and 1.2V regulator. Refer to Block Diagram. Y 4 The modular transmitter must comply with the antenna and transmission system requirements of Sections 15.203, 15.204(b) and 15.204(c). The antenna must either be permanently attached or employ a “unique” antenna coupler (at all connections between the module and the antenna, including the cable). The “professional installation” provision of Section 15.203 is not applicable to modules but can apply to limited modular approvals under paragraph (b) of this section. The device is equipped with the permanently attached antenna. Any connector isn’t used. Refer to Antenna specification ・ Y 5 The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing for compliance with Part 15 requirements.
