Power lamp
Lights (green): The power is on.
Blinks: The unit is reading/writing data.
Card box
You can store two SD cards here.
Note 1: When the connection between NavNet VX2-BB and memory card interface unit is wrong,
the NavNet VX2-BB searches for chart data in the SD card for 50 seconds, and then returns to
the normal operation. The display looks frozen, however normal operation will be restarted after
the search is completed.
Note 2:
To prevent loss of card data if the power suddenly goes off, it is recommended that
you periodically back up data to an SD card.
