AVATAR GOGGLES L
Upgrade
Please go to the official website to download the upgrade firmware,
AvatarLite_Gnd_X.X.X.img is the Goggles file, copy it to the SD card, be careful
not to change the file name.
1. Copy the upgrade file to the root directory of the SD card,
connect to the power supply and wait for the device to initialize
(delete the old firmware file first if there in one).
2. Press and hold the link button on the Goggles for 8 seconds, and the
Goggles automatically restart and emit a beep...beep...beeper sound.
(Do not power off during the upgrade process, the upgrade time on the
goggle is about 6 minutes)
3. After the upgrade is successful,and the beeping sound stops after the
Goggles beeps for 5 seconds.
1. Connect the VTX and the power of the Goggles.
2. Press the link button of the VTX and Goggles respectively (as shown in the
picture), when the VTX enters the pairing state The indicator light turns
red, and the Goggles end is a DI... DI... DI...
3. After the link is successful, the indicator light on the VTX turns solid green,
the beeping sound on the Goggles stops and the screen is displayed.
Detect VTX voltage, intelligently identify the voltage of 2, 3, 4, 6 string LiPo
batteries, alarm when a single battery is lower than 3.5V, and alarm in red
font when the voltage is too low.
1-VTX input voltage：
Detect Goggles low battery alarm, intelligently identify the voltage of 2, 3, 4,
6 string LiPo batteries, alarm when a single battery is lower than 3.5V, red
font and buzzer alarm when the voltage is too low.
2-Goggles input voltage:
Display real-time transmission code rate, two display modes of 25.0Mbps
and 50.0Mbps.
3-Real-time bit rate
Displays the total delay from the transmission of images captured by the
VTX camera to the ground end.
4-Time delay：
The function of calculating the transmission distance from Goggles to VTX
according to the wireless transmission delay, the signal is interfered will
lead to error amplification。
5-Ranging mode：
The text prompts information that needs attention in the current state.
6-Status prompt：
Display the current setting channel, the signal grid has 5 states, 4 grids,
3 grids, 2 grids, 1 grid, and blank.
7-Current channel：
Display the status and remaining capacity of the Goggles SD card. When
recording, the red circle flashes to prompt, the status of the SD card not
detected is displayed as NO SD, and the status of the memory is full is
displayed as -.
8-Goggles SD card status：
Display the status and remaining capacity of the VTX storage, When
recording, the red circle flashes to prompt, the status of the storage not
detected is displayed as NO SD, and the status of the memory is full is
displayed as -.

1、Display the interference situation of each channel. The signal strength is
divided into 4 grids, 3 grids, 2 grids, 1 grid, and a space. The signal display
space is occupied and cannot be selected. The white stroke is the selection
box. Press the middle button to confirm the current channel and highlight it.
2、 Channel working logic: When switching between standard bit rate and
high bit rate, the current channel will be set to CHP, and the channel needs
to be reselected. CHP is a public channel, which is easy to be interfered and
is not recommended for flight work; Auto is a channel that automatically
refreshes the signal interference situation of all channels; Refresh is the
channel of manual refresh.
3、Channel display of each country: FCC standard displays 8 channels
(CH1/2/3/4/5/6/7/P), CE/SRRC standard displays 4 channels (CH1/2/3/P),
MIC standard displays 3 channels (CH1/2/P). Only in FCC mode, the high bit
rate mode can be turned on, and the 8 channels become 4 channels CH1,
CH2, CH3, CHP.

1. This is a sophisticated product. Failure to operate this product in a safe
and responsible manner could result in injury or damage to the product or
other property. lt must be operated with caution and common sense and
requires some basic mechanical knowledge.
2. The transmit power of VTX and Goggles is only 10mW when the standby
mode is on.
3. There are up to eight channels for the goggles depending on the region
(FCC: eight, CE/SRRC: four, MIC: three). Each channel has a bandwidth
of 20 MHz. The public channel is 8, which is the default channel when the
equipment is powered on. The channel can be changed manually to avoid
interference from other devices.
4. It is recommended to upgrade VTX and Goggles to the latest firmware
before first use.
1、The OSD switch can be turned on or off. When it is turned on, the flight
control OSD information (if any) and the flight information of the main
interface will be superimposed on the playing video interface. When the
selection box stays in the video list, press and hold the Goggles confirmation
key to open the multi-selection function, and the menu box will display
function settings (delete, select all) , cancel), press the return key again to
exit the multi-selection mode.
