The Model LEA-3-WATT transmitter is a high performance video transmitter designed specifically for Law Enforcement Agencies. Application The Model LEA-3-WATT video transmitter is specifically designed for the broadcast of standard NTSC signals to be received and processed by a broadcast video receiver, providing a wireless link for closed circuit television systems. The output power of the transmitter is almost 3 Watts. This transmitter has been designated for mobile applications. This transmitter is type accepted for licensed use under FCC rules Part 90 for use in the 2450 to 2483.5 MHz frequency band. This transmitter has a fixed transmit frequency of 2470 MHz. Intended users include state and local agencies of law enforcement, fire departments or other public safety organizations or agencies. This equipment is EMI/RFI sealed and is intended to be dust, water and weather resistant under normal environmental and operating conditions. Any attempt to open the unit or to expose the internal components, by other than a manufactures authorized technician, will violate the integrity of the sealing system and will invalidate the warranty. Cautions A suitable 50-Ohm antenna or load should be connected to the RF output of the transmitter before applying DC input power. Do not apply more than 14 VDC on the input power. Installation Ideally, the transmitter should be located such that the space between the transmit and receive antennas is unobstructed. Physical, man-made and environmental structures or topographical features between the antenna will absorb or reflect transmitted signals; reducing or limiting the transmit range. Metal or metalized material in the antenna wave pattern will cause signals to be reflected. Other structural and physical obstructions, i.e., concrete, glass, trees, etc. will cause the transmitted signals to be attenuated by absorption to some degree. Even though the transmitter is sealed and is water resistant it is not intended to be installed outdoors. This transmitter has been designated for mobile applications. Do not place the transmitter antenna in close proximity to another transmitting antenna. Operation The transmitter is provided with a 0 dBi dipole antenna connected to the external antenna connector. For other antenna options please contact Gamut Electronics LLC. 4 Users Manual Users Manual Users Manual Users Manual Apply DC power to the transmitter using a battery or power supply. The transmitter has been deigned to operate from +12 VDC 15%. When operated at +12 VDC, input current is about 1.5 Amp. Power sources should be stable, regulated and be capable of supplying slightly more than the required current. When connecting to a battery, the red alligator clip is positive (+) and the black alligator clip is negative (-). The NTSC 1 V p-p video output of the camera is connected to the BNC (female) video input of the transmitter via standard 75-Ohm coaxial cable such as RG-59. Long lengths (>50 feet) of coaxial may begin to pick up interference so try to keep this length to a minimum. The Audio input is designed to receive mic level type signal levels. These levels are very low at approximately 150 millivolts or less. Please contact the factory for setting the audio input to line level. FCC Information This equipment has been tested and found to comply with the requirements for a FCC Part 90 transmitter in the 2450 2483.5 MHz band. If you do not already posses an FCC license that covers this same frequency band and RF power as this transmitter, you must apply on-line with the FCC at http://www.fcc.gov to receive approval to operate the transmitter. You will need to file for a Special Temporary Authority (STA) application in order to operate the transmitter within a few days. In order to operate the transmitter permanently you will need to file an FCC Form 601 on-line. For assistance in filing with the FCC please contact Gamut Electronics. FCC ID:

P7F-FCCPART90-3W P7F LEA-3-WATT 15M8F3W PW (Public Safety) 2470 MHz Just under 3 WATTS (34.7dBm) RF Exposure Information This transmitter complies with the controlled/uncontrolled exposure limits pursuant to FCC rule parts 1.1307, 1.1308, 1.1309, 1.1310, 1.1311 and 2.1091. Pursuant to 47 CFR Part 2.1091(b), this device is not subject to routine environmental evaluation for RF exposure prior to equipment authorization or use. The RF power level is less than 3.0 Watts and operates at a frequency above 1.5 GHz. Pursuant to 47 CFR Part 2.1091(b), this device satisfies the MPE Categorical Exclusion Requirements. An analysis of the proposed radiation levels per criteria set forth in OST bulletin 65 have not revealed any hazards to humans. 5 Users Manual Users Manual Users Manual Users Manual Service & Maintenance The transmitter contains no user adjustments inside the unit, so the cover should never be removed. Any unit requiring service or repair must be returned to the manufacturer or the manufacturers authorized representative. Warranty Gamut Electronics LLC warrants it devices and equipment for a period of one (1) year from date of purchase to be free from defects in workmanship or materials. This warranty is limited to replacing, repairing or issuing credit, at its option, any device which is returned during the warranty period.
