Linking is the process of pairing the video goggles with the video transmitter. You will need to complete the linking process in order for the goggles to receive
video from the transmitter. You can link multiple transmitters to the same set of goggles.
1. Power ON the goggles. Wait for the goggles to display the main standby screen.
2. Power ON the video transmitter. Wait for the LED to blink green.
3. Press the link button on the video transmitter, the LED on the video transmitter turns red.
4. Use a tool to press the link button on the goggles; they will beep to indicate link mode.
5. When linking is complete, the goggles will stop beeping and the LED on the transmitter will turn green.
LINKING
• The transmitter will not send a video signal unless the goggle it is linked to is turned on.
• The transmitter will power up and transmit on the channel selected at the goggle.
• By default, the Public Channel will be selected. This channel should not be used for flying your drone and should only be used
to select a channel for operation.
• The system may prevent you from selecting channels currently in use by other pilots.
• Once you have selected a channel, the goggle and transmitter will go to your selected channel on future power ups.
• If your previously selected channel is occupied by another pilot while your system is not powered up, the system may default
back to Public Channel and prompt you to pick a dierent channel.

TROUBLESHOOTING
Problem Possible Problem Possible Solution
Video recording not
working
SD card not set to correct format Reformat the SD card using the goggles
Less than 200MB available on the SD card Replace the card or clear o some space on the card and try again
Not a solid video signal Focus on reception first
Poor reception
RC antennas too close to video antennas Maintain maximum separation between RC antennas and video antennas
Shadowing of VTX antenna Try a dierent VTX antenna with a longer coaxial section to get the active element
further from carbon fiber or metal parts
VTX antenna connection loose
Ensure the VTX antenna and any adapters in use are secured and solidly
connected. If the antenna becomes disconnected during operation it will degrade
performance and may cause permanent damage to the VTX.
VTX has entered overheat protection mode
Disconnect power and allow the video transmitter to cool, then reconnect power
and try again.
Improve airflow to the video transmitter RF board in your installation.
In unconventional installations with poor ventilation, consider adding a cooling fan
to improve air flow.
Loose antenna connection on video transmitter Make sure antenna connector is seated securely
Interference from other source of RF Move goggle away from possible sources or RF interference such as wifi routers,
high power transformers, etc
White dead areas appear
on screen Damage from sunlight
Keep the goggles from being exposed to direct sunlight on the optics to prevent
further damage. Contact service for a repair quote. Damage from sunlight is not
covered under warranty.
