FCC STATEMENT 1. 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. (2) This device must accept any interference received, including interference that may cause undesired operation. 2. Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. RF warning statement: The device has been evaluated to meet general RF exposure requirement. The device can be used in portable exposure condition without restriction.

Tel: 13809602678 Fax: 0750-7815638 FCC ID: S32G-622 Operation Description General Description The EUT is powered by 3VDC battery （1.5V*2 AA batteries ） and have one channel between 614.0 MHz to 697.0MHz UHF audio transmitter， it’s Occupied Bandwidth is 100kHz，it cannot be tuned by the end user。 Wireless microphone circuit description of G-787 AUDIO CIRCUIT The audio signal is injected via the microphone sensor into the audio circuit composed of the op. amp IC4 （MC4558）, & compandor IC3 （SA571）. The signal is compressed via the compandor circuit at a 2:1 ratio and is pre-emphasized by U2. The level of the output signal is controlled by the resistors R45 (10K VR) and R37, R47 to VCO. MODULATOR CIRCUIT The modulator circuit is a direct FM type built around the local oscillator controlled by Crystal X301(10MHz), VCO(IC302 MCD8825B), PLL(IC301 MB15E03). The modulated output from the oscillator is sent to the RF pre-amp. Frequency Set: The frequency can be chosen by setting switch (AN1) or by an IR sensor and the CPU(IC1 16F73 clock 4MHz). And the signal from CPU to PLL can control the carrier frequency. RF PRE-AMPLIFIER & FINAL AMPLIFIER The 2-stage amplifier, using two transistors Q303(Y7) and Q304(R37), culminating with a normal transmitter output of <1mW. The precious LC output filter (L310-314, C333-342) suppress the output harmonics and matches the output to the integrate antenna. LCD DISPLAY CIRCUIT The LCD display (LCD T4036) is driven by IC5(HT1621) and showing the frequency etc. signals output by CPU. POWER STEADY CIRCUIT Use 2xAA batteries as power supply, Q4 (2SC4081) and Q3 (2SD2098) rise the voltage to 7.5V for audio part, and to U1(7805 5V) for CPU also the LCD, PLL and RF AMP. ANT TYPE: Whip ant Modulation Type： 100k F3E Operational frequency range： 614M—697M Hz
