AV-IN Port Definition:

1. GND
2. CVBS (Connect to Analog Receiver Video Signal)
3. RX
4. TX
5. NC

Linking

1. Connect the VTX and power the Goggles.
2. Press the link button on both the VTX and Goggles. The VTX indicator light turns red when in pairing state, and the Goggles will emit a beeping sound.
3. Upon successful linking, the VTX indicator light will turn solid green, and the Goggles will stop beeping and display the screen.

Upgrade

Download the latest firmware from the official website. The file is named 'AvatarX_Gnd_X.X.X.img'. Copy it to the SD card without changing the filename.

1. Copy the upgrade file to the root directory of the SD card. Connect to power and wait for initialization (delete old firmware if present).
2. Press and hold the link button on the Goggles for 8 seconds. The Goggles will restart and emit a series of beeps. Do not power off during the upgrade (approx. 6 minutes).
3. Successful upgrade is indicated by the beeping stopping after 5 seconds.

Status Indication

Goggles Buzzer Status:

• Link state: DI.... DI.... DI.... DI....
• Upgrade firmware: DI...... DI...... DI...... DI-
• Upgrade failed (No SD card or firmware detected): DI.. DI.. DI.. DI..
• Boot failure (Reboot or re-upgrade): DI.. DI...... DI.. DI......

Operating Channel Frequency (MHz):

Important Regulatory Note: Abide by local laws. An amateur radio license may be required in FCC regions for certain channels (1, 2, 6, 7) which are amateur frequency bands. Unauthorized use may result in legal penalties.

Installation of Third-Party Antennas

1. Turn counterclockwise to remove the antenna.
2. Turn counterclockwise to remove the nut and circular washer.
3. Turn clockwise to install a third-party antenna.

Precautions

• Operate this sophisticated product responsibly to avoid injury or damage. Use caution and common sense.
• Install all antennas before powering on to prevent component damage.
• When using HDMI output, ensure the monitor supports the set resolution and frame rate to avoid display issues.
• HDMI output is not available when goggles are set to 1080p high frame rate.
• VTX and Goggles transmit power is 10mW in standby mode.
• Goggles support up to eight channels depending on the region (FCC: 8, CE/SRRC: 4, MIC: 3), each with a 20 MHz bandwidth. Channel 8 is the default. Manual channel changes can avoid interference.
• It is recommended to upgrade VTX and Goggles to the latest firmware before first use.

Software Interface

Main Interface-1

Displays VTX input voltage, Goggles input voltage, real-time bit rate, time delay, ranging mode, status prompts, current channel, Goggles SD card status, and VTX storage status.

• 1-VTX input voltage: Detects VTX voltage (2S-6S LiPo). Alarms below 3.5V per cell.
• 2-Goggles input voltage: Detects Goggles battery level (2S-6S LiPo). Alarms below 3.5V per cell.
• 3-Real-time bit rate: Shows transmission code rate (25.0Mbps or 50.0Mbps).
• 4-Time delay: Displays total delay from VTX camera to ground end.
• 5-Ranging mode: Calculates transmission distance based on wireless transmission delay. Interference can cause errors.
• 6-Status prompt: Provides current state information.
• 7-Current channel: Shows the current channel and signal strength (5 states).
• 8-Goggles SD card status: Displays SD card status and capacity. Flashes red when recording. 'NO SD' if not detected, '-' if full.
• 9-VTX storage status: Displays VTX storage status and capacity. Flashes red when recording. 'NO SD' if not detected, '-' if full.

Menu Channel-2

Allows selection and viewing of channel interference. Displays signal strength in grids. White stroke indicates the selection box. Pressing the middle button confirms the channel.

• Channel working logic: Switching bit rates may set the channel to CHP (public, prone to interference). 'Auto' refreshes signal interference. 'Refresh' manually refreshes channels.
• Channel display by country: FCC displays 8 channels; CE/SRRC displays 4; MIC displays 3. High bit rate mode (FCC only) reduces channels to CH1, CH2, CH3, CHP.

Menu Settings-3

Provides access to various adjustable settings:

• 1-Camera: Scene preset, EV value, saturation, sharpness, white balance, rotate, ratio, 3D DNR, Shutter, Max ISO.
• 2-Display: Debug, brightness, focalization mode, custom OSD, OSD position, font upgrade, custom font, viewfinder settings.
• 3-Record set: VTX REC resolution, REC device, takeoff REC, REC loop, format SD card, format VTX, Built-in EIS, REC Time, REC Format, Color, Saturation, Sharpness.
• 4-Device: Buzzer volume, Ranging mode, Weak signal, Reset all, Device information, Instruction, Switch mode.
• 5-Transmit Power: Options include 25mW, 200mW, 500mW, 700mW.
• 6-Resolution: Options are 720P and 1080P.
• 7-Bitrate: Standard or high bit rate (high bit rate only in FCC mode).
• 8-Frame Rate: Standard or high frame rate.
• 9-Standby Mode: Reduces VTX and Goggles transmit power to 10dBm. Requires correct air unit serial port connection to flight controller for automatic exit upon receiving unlock signal. Can be turned off if no flight controller support.
• 10-Language: Switch between English and Chinese.
• 11-Low Battery: Detects Goggles low battery alarm (2S-6S LiPo). Alarms below 3.5V per cell.
• 12-Goggle icon: Option to display or hide icons on the main menu.
• 13-Broadcast: Allows others to receive your video transmission via the Avatar system. The 6 characters in brackets are the VTX's unique identification number.

Menu Playback-4

Allows playback of recorded videos. Videos are listed with filenames like 'AvatarG0000.mp4'.

• The OSD switch can be turned on or off to overlay flight control OSD information and main interface flight information onto the playback video.
• In the video list, a long press of the VRX confirmation key opens multi-selection functions (delete, select all, cancel). Pressing the back key exits multi-selection mode.
• Playback controls: Middle button pauses/plays; left/right arrow keys rewind/fast forward.
