2.4 GHz AUDIO/ VIDEO TRANSMITTER MX 3000
MX 3000 is a smallest Audio/ Video transmitter for 2,4 GHz and measures only 1.5” X 1” X 0.3”. 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/ 140 m A. The video level can
be adjusted with the potentiometer on the board. VRX 24 L receiver is matching unit for this transmitter. 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. Sound is excellent quality with a microphone built-in. Recommended receiver is
VRX 24L (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.

FREQUENCY SETTINGS AND POWER UP:
Powerup
At powerup, the unit will retrieve the last used channel, program the PLL with this channel, and display the
channel by blinking the LED the same number as the channel number 7 or 8.
Displaying Current Channel
Push button is located on the board. To display the current channel, press the pushbutton once and release.
The current channel will blink. After approx. 5 seconds, the current channel will again blink.
Changing to a New Channel
/ Frequency allocation /
Important message to users
To change to a new channel, press the pushbutton once and release. The current channel will blink. Press
and release the pushbutton again before 5 seconds has elapsed and the channel will increment by 1 and the
LED will blink the new channel. You must count to 7 in order to set the first user’s channel frequency 2452
MHz, the next channel is channel 8 (LED will blink 8 times), it means that unit is set to Channel 8
frequency 2481 MHz. Repeat this step until the desired channel is reached (channel 7 or channel 8), waiting
for the blinking to stop each time before pressing the button again.
Once your desired channel is reached (7 or 8), wait 5 seconds until the LED again blinks your desired
channel. Your new channel is now saved in memory. If unit turned off, the microprocessor will save in
memory the last used channel.
Channels 7 and 8 have been in use
FREQUENCIES: 2452 MHz and 2481 MHz
NOTE: DO NOT USE ANY OTHER CHANNELS (FREQUENCIES) OUTSIDE OF FCC LIMITS.
USE STRICTLY CHANNELS 7 or 8. THE OTHER CHANNELS (FREQUENCIES) OUTSIDE OF THE
AUTHORIZED BAND ARE PROHIBITED AND NOT RECOMMENDED BY THE MANUFACTURER!
ALL WARRANTIES VOID IF MODIFIED!
