Introduction
The AVL58 includes both Video Link Transmitter (TX) and Video Link Receiver (RX), working in the ISM
frequency band of 5.8GHz (5645- 5945MHz MHz). Analogue modulated video signals are sent wirelessly
by the TX module to the RX module, and then the video signal will be demodulated and sent to a display.
There are 8 wireless channels can be selected when you are using AVL58. These channels are:
CH1-5705MHZ, CH2-5685MHZ, CH3-5665MHZ, CH4-5645MHZ, CH5-5885MHZ, CH6-5905MHZ,
CH7-5925MHZ, and CH8-5945MHZ.
The characteristics of the AVL58 are: small size, low power consumption and high sensitivity. The AVL58
can be used in many applications requiring wireless video communication. When it’s used in the
aero-modeling hobby, the Video Link Transmitter will be mounted to the aircraft and the Video Link
Receiver is connected to a display screen, allowing video signal wireless transmission.

Important:
 The antenna MUST be connected before power on, otherwise electronics damage may occur.

When use a battery to supply power for the RX and the display screen, the battery voltage must
not be higher than the input voltage of the display screen; otherwise damage may occur to your
display screen.
 Ensure there is no obstacle between antennas; otherwise the communication range will be reduced.
