4. 5. 6. 7. 8. DURING INSTALLATION, DO NOT OPERATE TRANSMITTER WITHOUT ANTENNA CONNECTED TO ANTENNA PORT. Failure to do so will result in damage to the unit and void the warranty. The transmitter is FCC approved under FCC ID: OPH-MINITX4000. Changes or modifications not expressly approved by K&A Wireless, LLC will void the user’s authority to operate the equipment. This product must be professionally installed.
The modular transmitter must have its own power supply regulation. Modular TX contains a power regulator for most of the circuitry. However the RF Power Amplifier receives voltage directly from the input. The input voltage is required to be between 3 and 5Vdc and the RF PA, would stop operating if 6V or higher are connected to it (Datasheet attached). The operating voltage is clearly noted in the Users Manual.
Rules. These limits are designed to provide reasonable protection against harmful interference. 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, and (2) this device must accept any interference received, including interference that may cause undesired operation. Emission designator for the FM-TX-4000 Mini series transmitter unit is: 13M7F3F. The transmitter label is shown below.
limits. This device is not authorized for general population, consumer or any other use. This module is approved for operation as a single modular approval under FCC Part 90. For compliance with FCC RF Exposure requirements the following requirements shall be met: The module can be used with an antenna with a maximum gain of 15dBi.

PARTS LIST The FM-TX-4000 series Analog Video Transmission system comes complete with the following items: 1. 2. FM-TX-4000 Mini series transmitter Wire Dipole antenna The transmitter operation can be confirmed by using a EVRX-2000 series receiver unit from K&A. This receiver series displays the video images on an NTSC compatible (PAL compatible, if your camera source is PAL) monitor.
solution to long-range transmission available for industrial, government/municipality or for export applications. The ISM band is a harmonized band and is available worldwide. In the US, however, the FM-TX-4000 Mini series transmitter is designated for PART 90 use and requires a license to be obtained by the end user.
Figure 2. Photo and K&A drawing for FM-TX-4000, wire dipole antenna, and MMCX male to SMA female coax. The transmitter is supplied with a K&A antenna (part #: TBA) to comply with FCC regulations, as shown in Figure 2. Any attempt to operate the system without an antenna or an antenna that is not approved by K&A, in writing, will result in damage to the system and will nullify any warranty and MAY VIOLATE FCC LICENSE AGREEMENT. Figure 3.
Transmitter Installation The transmitter is designed to be integrated into your camera system. To install the transmitter, connect the red wire to the battery (or regulator output), connect the black wire to ground or the negative terminal of your battery (or regulator output). For the video connection, you should have requested either a high-Z or low-Z video input. This is the termination setting.
