18.2 MDR Fireproof Box
•
When you connect a Fireproof box to the MDR.
This needs to be enabled in the OSD. Go to

The MDR may restart to engage this new
hardware device.
•
All new fireproof boxes must be formatted before
use.
•
Please follow the below steps to do this:
➢
Format as FAT32 first so the correct storage
capacity displays
➢
Then format as MDR5 so the MDR can
record to this storage
