Operating channel

Make sure you fully understand and abide by local laws and regulations before using this product. An amateur radio license may be needed in FCC regions when using channels 1,2,6or 7, as they are amateur frequency bands. Users who use the amateur frequency bands with a modiﬁed or cracked version or without a license may be punished for breaking local laws or regulations.

Precautions

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.
The transmit power of VTX and Goggles is only 10mW when the standby mode is on.
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.

Software interface

Main interface-1

VTX input voltage：
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.
Goggles 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.
Real-time bit rate
Display real-time transmission code rate, two display modes of 25.0Mbps and 50.0Mbps.
Time delay：
Displays the total delay from the transmission of images captured by the VTX camera to the ground end.
Ranging mode：
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。
