Connecting the receiver antenna. (Figure 1) 2. Connecting the 9V direct current stabilizer (Figure 2), pilot lamp lighting (Figure 3). 3. Connecting the audio and video (figure 4) output with the input to the monitor, the television should be set on A/V model. 4. Connecting the audio and video output with the input of the transmitter. 5. Plug power jack of DC power supply(8V , 300mA)into the power socket of the CMOS camera(figure 6).(Battery of the same voltage is acceptable.) 6. Turning the micro-adjustment knob (figure 5)on the receiver till receiving the picture of the wireless camera. 7. Fine tune to the desire position till the image of CMOS camera is received. 8. Adjust the lens of the CMOS camera (figure 7) to best position. Notice 1. The machine is supplied with many different types, please provide with electric power according the value on the label. 2. Obstructs by the building and so in will cause attenuation. 3. Normally that the machine will slightly warm up during operation. 4. Should any other malfunctions occur, please contact local distributor. 5. Under normal operational conditions, one year’s warranty is granted .if there are quality problems within 3 months, this company will unconditionally replace with a new camera. Waning This product is for the sole purpose of security and applicable for monitoring in residential houses, shop sand companies the users shall observe local rules, regulations and laws, and shall be solely liable in this regard, this company shall not be liable for any illegalities therein. 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: - 3 - --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.

Circuit Description The transmitter is made up of two parts: Audio &Video lDlit and RF unit.The audio signal fromMICl is amplified, then modulates the audio carry frequency oscillator (5.5MHz), the modulated carry frequency is added in the VT of voltage controlled oscillator VCO2 (2.4GHz, Dl,Ql). The video signal from CMOS camera passes through the sharp network(R21,R14, Cl,Cll), also is added in the VT ofVCO2, another signal is added in the VT ofVCO2 is the error voltage output of loop filter (Rl,R24-R26,C17,C19,C25) ofPLL(UI) which is progranmled by CPU(U3), the channel data is decided by the encode switch(SWl) of CPU's peripheries. The feed back signal(R30,C29) from voltage controlled oscillator VCO2 is compared with reference crystal oscillator, the error frequency of oscillator VCO2 can be corrected. The carry frequency to be modulated by audio &video has been power amplified by Q2, filtered through the band pass fIlter(C20,C18,C23, microstrip)which the higher harmonica of signal reduced to lower level. The purer signal is emitted by antenna(RFOUT). 3
