2.4 GHz AUDIO/ VIDEO TRANSMITTER
LX 3000/MIL
LX 3000/MIL is an Audio/ Video transmitter for 2,4 GHz and measures only 6.5” X 3.5” X 2.0”. It is fully synthesized 8
channels PLL unit, made for SECURITY applications, testing and experiments! This transmitter has built a preemphasis
filter for the best picture quality! Power supply is 9 -12 V/ 1700 m A. It comes with a full 1-year warranty. The antenna
connector is an SMA type. The range can be increased using the special high gain antennas. Recommended receiver is
VRX 24 (PART 15 FCC rules). Recommended antenna for the transmitter is a small dipole 0 dBi or less for a short range
or directional high gain antenna up to 14 dBi. Two channels have been in use: 2452 MHz and 2481 MHz. LX-3000/MIL
contain an FCC approved module MX-3000.

FCC INFO:
This equipment has been tested and found to comply with the limits for Class B digital devices, pursuant to
Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses, and can radiate radio frequency
energy and, if not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur
