•In video mode, DVR will automatically start to record if there is valid video signal and SD card is
inserted with over 200MB free space.

•Switching to setup mode will stop recording, and switching back to video mode will start recording
but to a different file.
•Status LED ④ will lit when powered on, and blink if recording in progress.
•The record will not start if there is no SD inserted or no enough free space.
•The recorded files are named as SB_XXX.TS. XXX is automatically increased for next file.
SD Card
•Format SD card before using:
- Use VRX to format SD card
- Use Windows to format (Choose FAT32 and Allocation Unit size to 4096 bytes)
•An 8GB-32GB SD card is recommended
Antennas
•The 4 SMA connectors allow you to select antennas that best fit your flying environment.
•It is highly recommended to attach antennas to all 4 SMA connectors.
•For best results, use matching antennas for the two top SMA connectors, and matching antennas for
the two side SMA connectors.
•The antennas should be 5.8 GHz antennas. If using polarized antennas, right-hand circular polarized
(RHCP) antennas are recommended.
