PPI symbols

Range rings and heading line symbols can be turned on and off individually from the PPI
symbols sub menu.
The Overlay graphic off menu option turns off all graphics overlaid on the radar PPI,
showing only the video signal.
Note:
The Heading line off and Overlay graphic off menu options are mono stable,
meaning that you need to press and hold the ENT key or the right arrow key to
temporarily remove the relevant symbols from the panel. The graphics are invisible as
long as the key is pressed, and will turn on again when the key is released.

Picture freeze indicator

The Own ship information area includes a picture freeze indicator (A). The small dot blinks at
an interval of 1 second to show that the screen is alive and that information from sensors are
updated.
If the picture freezes the R3016 Control unit needs to be restarted.
