 Circuit Analysis: 

• Q3, VC1, C13, C16 and L3 all make up a colpitts oscillator circuit that fluctuates form 220~250MHz. You can regulate the frequency to any value within this threshold by tuning VC1 or L3. C13 modulates the signal rate. When the capacitance increases, so does the modulation. R9 and C16 bias the local oscillation. If you lower R9's frequency to 680W the oscillator's output level will increase.
• Q2 and L2 act as a frequency doubler. C7, along with FCZ7S3R5 (IF transformer), the Q4 transistor, C14, C19 and R12 all make up the mixer. This mixer takes both audio and visual signals together and "mix" them into one and passes through RF Amplifier Q1 to transmit the signal to the antenna.

Installation:

• Fix the Transmitter, using the RCA Video, the Audio signal cable connect the transmitter and the single original equipment (eg, Camera, VCD)
• Check the two machine on the suitable position, then inserting the power adapter
• The Transmitter's installation is nearly the same as the receiver's, just the receiver need to be connected with the display equipment
• Confirm that it's right to install the Transmitter and the Receiver in two places, you can open all the power switches and set the Transmitter and the Receiver as the same channel
• Observe the accepting effect, by adjusting the tact of the angle of the Transmitter and the Receiver' antenna until get the excellent Video and Audio effect, the installation is over

Attention:

• If the original launch signal is one Audio channel, both of the Transmitter's Audio input and Receiver's Audio output should choose the same Audio channel, if the original launch is no Audio, the Audio line don't be connected
