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:

z The antenna MUST be connected before power on, otherwise electronics damage may occur.

z 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.

z Ensure there is no obstacle between antennas; otherwise the communication range will be reduced.

Trouble Shooting

No. What Why How to

1

Power supply is 

OK, but no video

There is problem with the video 

input.

Please check the video input.

2 No video

The RX and TX modules are not 

set to the same channel.

Make sure RX and TX modules are 

on the same channel by using the 

channel-selection button.

3

Video is flashing 

and rolling.

1. The video mode of the display 

screen sets incorrectly.

2. The RX and TX modules are 

not set to the same channel.

1. Reset the video mode of the 

display screen.

2. Make sure RX and TX modules 

are on the same channel.

4

The transmission

distance between 

the RX and TX is 

shortening.

1. The antenna assembly is 

incorrect.

2. The RX and TX modules are 

not set to the same channel.

1. Make sure there is no obstacle 

between antennas.

2. Make sure RX and TX modules
