# Introduction

The AVL58 includes both Video Link T ransmitter (TX) and Video Link R eceiver (RX), working in the ISM

frequency band of 5.8GHz ( 5 645

- 5 94 5MHz 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

. T hese channels are:

CH1

- 5705MHZ, CH2

- 5685MHZ, CH3

- 5665MHZ, CH4

- 5645MHZ, CH5

- 5885MHZ, CH6

- 5905MHZ,

CH7

- 5925MHZ, and CH8

- 5945MHZ.

The characteristics of the AVL5 8 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 T ransmitter will be mounted to the aircraft and the Video Link

R eceiver is connected to a display screen, allowing video signal wireless transmission.

Important:

z The a ntenna 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 En sure there is no obstacle between antennas; otherwise the communication range will be reduced.

on the same channel by using the

channel

- selection button.

3 Video is flashing

and rolling. 1. T he video mode of the display

screen set s incorrectly

.

2. The RX and TX modules are

not set to the same channel. 1. Reset the video mode of the

display screen.

2. M ake sure RX and TX modules

are on the same channel

.

distance between

the RX and TX is

shortening

. 1. T he antenna assembly is

incorrect

.

2. The RX and TX modules are
