Operate the radio
·Install Battery: remove the back cover of the transmitter, connect the battery inside to the
power interface correctly, and install the back cover.
·Power On: Long press the power button for about 3 seconds, then pull the throttle to the
lowest position, release the button after the radio vibrates twice, and the power indicator
turns from green to blue, indicating that the radio is turned on.
·Binding: 1. First press and hold the bind of the receiver, and then power on the aircraft (the
receiver's traffic light is always on at this time)
2. After the remote control is turned on, short press the Bind button on the back of the
remote control, the power indicator will be red
The color and blue flash alternately and enter the linking state for about 10 seconds.
3. If the receiver flashes red, it means the linking is successful
4. After successful linking, the aircraft can be used again after power on
If it is unsuccessful, repeat the above actions and link again. When the throttle is hit to the
lowest level, toggle switch A to unlock, and the motor starts to rotate.
·Power Off: press and hold the power button for about 5 seconds, release the button after
the transmitter vibrates, and the power indicator light turns off, transmitter is turned off.
· Charge: the power indicator light flashes blue slowly and vibrates when the battery
approaches the low voltage limit. it need to be stopped immediately. Connect the USB cable
to the power supply, and the power LED will show
·red when charging; the power LED turns off after the charging process is done.

NVISION A01 VTX
Description:
*Switchable power includes 0mW, 25mW and 200mW.
*This VTX includes SmartAudio function. The flight controller can use the audio cable to
communicate with the video transmitter. It allows the flight controller to know the frequency
used by the VTX and make changes.
*This VTX supports PitMode.
*Dipole whip high sensitivity antenna. It is mounted to the VTX board durable.
*Output power: 0mW, 25mW and 200mW (adjustable)
*Power supply voltage: 5V. Does not support direct connection to 1S battery
*Weight: 2.0g
*Frequency: 5.8GHz 6 frequency band 48 channels, competition frequency band:
5362~5945MHz
Component Layout Diagram for NVISION A01 VTX:

How to Change Frequency & Channel & Power
Only support frequency and power change through the SmartAudio interface.
Method 1: Use the OSD menu.
Enter the OSD menu by radio transmitter sticks ( Pitch Stick UP and Yaw Stick Left). Then
FEATURES -> VTX SA to change the frequency and power.

Me tho d 2: Use the Betaflight GUI comman d.
We could also use the Be taflight CLI commands to ch ange the frequency
and power of the VTX.
For example , set the frequency to 5865 and power to 200mW ( 1 for 25mW /
2 for 200mW);
set vtx _band=1
set vtx _channel=1
set vtx _freq=5865
set vtx_pow er = 2

How to Use the PitMod e
PitMode allows racers to power up their video transmitters during race events without
interfering with other racers and still having the ability to change VTX settings or do some
testing. Range is limited to 2-3m and transmission happens on the selected frequency.
The PitMode is active when only red LED flash solid.
How to active the PitMode: Ent er the OS D me nu by radio tra nsmit t er stic k s.
FEA TURE S -> VTX SA -> CO NFIG -> PI T FM ODE. Then sel ect the PIR sta t us.
How to exit the PitM ode : As the same abov e, se lect the OP MO DEL to FRE E
to clos e the PitM o de. Th en th e VTX wi ll re cove r to the 25mW powe r sta t us.
