To select either mode, move the toggle switch to the appropriate position as labeled on the unit. The center position is the OFF position. 3.2 Troubleshooting If the Chang Eye video transmitter fails to operate, check the following: 11 1. Is the lens cover removed? 2. Is the battery sufficiently charged? The unit has a shutdown voltage of ~2.9V. 3. Is the battery connected properly? 4. FCC Statement 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. Any changes or modifications not expressly approved by Chang Industry, Inc. can 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 A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the 12 instruction manual, may cause harmful interference in which case the user will be required to correct the interference at his own expense. 13 Wireless Hand Held Video Receiver, 2 channels or 4 channels 1. Description 1.1 Introduction The Wireless Hand Held Video Receiver, CE-R01x, is a portable video receiver that displays the video feed from a Chang Eye Video Transmitter. Currently, the units are available in one of two possible configurations; one version (CT-R012) is capable of receiving channels 1 & 2, the other version(CT-R014) is capable of receiving channels 1 through 4. The units can be powered either through the use of 8 high performance AA batteries or from an external power source. A video OUT connection is also provided( adaptor cord provided, video is RCA YELLOW plug) to allow …

CHANG Industry, Inc. 1925 McKinley Ave Ste. F Phone: 909 596-7888 La Verne, CA 91750 Fax: 909 596-8388 - 1 - August 24, 2005 CE-T010 Video Transmitter The video camera used in the transmitter is powered via a step up DC-DC converter, which transforms the 3.7-volt DC source voltage to a 9-volt DC source. The NTSC video signal from the camera is amplified using a video amplifier and linked to the VCO (voltage controlled oscillator) by means of the modulation coupling. The VCO is modulated with the video signal and controlled by way of the PLL (phase lock loop). The PLL uses a reference oscillator (crystal) and a micro controller to monitor the VCO’s frequency through a feedback network. The feedback network compares the phases of both the crystal and the VCO at a lower loop frequency and ultimately biases the VCO via a loop filter and a buffer amplifier to the correct fundamental frequency. The fundamental frequency passes through an attenuator and a filter to ensure signal integrity and proper broadcast level. Further, the fundamental frequency is amplified and filtered before connected to the antenna. Lastly, the unity gain omni-directional antenna is permanently attached with an electrical connection (soldered) for transmittal.
