A,
board size: Launch plate: 150 * 80mm
(excluding SMA and other prominent parts),
height
70mm
(excluding display part)
B, launch distance: greater than 8KM (the premise is that the open area, the antenna height is

Precautions for use:
A, The power supply is dc voltage. The input is positive and negative. The
voltage input range is 12-13v. The input ability of the power supply must not be
less than 8 amperes.
B, Antennas must be used to transmit antennas of 50 ohms. The
frequency range needs to be between 76-108MHZ. Note that the standing
wave ratio on the display should not be greater than 2.00 when used.
Operating instructions:
A
,frequency adjustment： Press the middle button for more than 5
seconds. The system then enters the interface to set parameters.
When the ‘FRE’ appears on the single screen, the frequency value
can be modified by pressing the UP key or Down key. The long
press KEY can adjust the frequency value quickly. After adjusting
the parameters, you can switch parameters or exit adjustment mode
according to the middle button.
B
,Power  adjustment： Press the middle button for more than 5
seconds. The system then enters the interface to set parameters.
When the ‘PO’ appears on the single screen, the frequency value
can be modified by pressing the UP key or Down key. After
adjusting the parameters, you can switch parameters or exit
adjustment mode according to the middle button.
C
,Volume  adjustment： Press the middle button for more than 5
seconds. The system then enters the interface to set parameters.
When the ‘VOL’ appears on the single screen, the frequency value
can be modified by pressing the UP key or Down key. After
adjusting the parameters, you can switch parameters or exit
adjustment mode according to the middle button.
D
,Player adjustment:  When the system is not in the parameter
adjustment interface, press UP KEY or DOWN KEY to switch the
