6. FAULT RECTIFICATION No picture : RF camera, receiver or monitor not correctly connected or not supplied with power The distance between RF camera and receiver is too great. A frequency of the camera has been adjusted differently from the receiver channel selected. Noisy picture : The distance between camera and receiver is too great. A frequency of the camera has been adjusted differently from the receiver channel selected. Metallic barriers exist at between camera and receiver. The RF camera and/or receiver antennas are placed or oriented disadvantageously. A strong source of interference exists at nearby. Supply voltage of a power source is too small.

Cauti of thi party autho USERS OPERATION MANUAL 2.4GHz RF (Tx) Color Camera Item No. : V-2297RF 1. PRODUCT DESCRIPTION The RF color camera unit consists of a color CMOS camera and a transmitter in a durable metal casing, and transmit a video signal by radio ; replacing complicated cabling. Features :
!!!! 1/3 format color camera with a transmitter
!!!! 2.4GHz carrier frequency, 50mW
!!!! Auto white balance, auto gain control & auto exposure
!!!! Durable metal casing
!!!! Compact size
!!!! Low power consumption, 55mA 2. SAFETY
!!!! When installing the unit, take care that the power cord does not become trapped or damaged by sharp edges.
!!!! Before connecting a power source to the unit, make sure that a supplied voltage is correct.
!!!! Disconnect the power cord when the unit is to be out of use for lengthy periods.
!!!! Never replace a damaged power cable personally.
!!!! Never bend or give a pressure to an antenna of the unit from any directions. 3. INSTALLATION AND OPERATION
(1) Make sure setting 2.4GHz video RF receiver and color monitor units properly.
(2) Turn RF receiver and monitoring units on, and select a frequency channel on a RF receiver.
(3) Connect power plug of the unit to a proper power supply source. (input voltage : 7.5 12vdc)
(4) Open a rear cap of the RF camera unit.
(5) Make a fine adjustment of a Tx radio frequency, to a Rx channel selected, by carefully rotating a VR located at right top side of the transmitter board with a non-metallic adjustment driver while observing a picture quality on a monitor for a stable and best reproduction. Caution - Be careful not to exceed adjustment range of the VR. If not, it can result a damage on the VR.
- Be careful not to touch any other parts of the board except the VR with a adjustment tool.
(6) Close a rear cap back.
(7) Place and mount the camera unit properly at a location with a desired view. 4. CARE AND MAINTENANCE The unit is maintenance-free, therefore never open it except for frequency and focus setting adjustments. The unit should be cleaned externally only with a soft, dry cloth or brush. 5. TECHNICAL DATA Operating voltage : 7.5 12vdc Current consumption : approx. 55mA Imager : 1/3 color CMOS sensor Number of pixels : 510 X 492 Gamma correction : 0.45 Transmitter frequency : 2.411GHz 2.473GHz Modulation : FM Output power : 10dBm Channel bandwidth : 8MHz Phase noise @10k : - 86dBc/Hz Frequency stability : -0.1% or better
