9.2 Digital radar scan speed
SuperHD open array radars with software version 3.23 or above or
HD digital radomes support multiple scan speeds.
Radar scan speed is set up using the Radar Set-up menu. When
the system detects a scanner that is capable of operating at both 24
RPM and 48 RPM, 2 options are provided for scanner speed:
• 24 RPM
• Auto
If you have a digital radar scanner that only operates at 24 RPM,
the scanner speed option is disabled. If the scanner speed option
is enabled, you must select the Auto option if you want to use the
higher scan speeds. This option automatically switches between the
24 RPM and 48 RPM scan speeds as appropriate.
Selecting radar scanner speed
The speed option requires a 48 RPM compatible Raymarine HD
digital radome or Raymarine SuperHD digital open array radar
scanner.
Select your radar scanner speed from within the radar application.
1. Select
Menu .
2. Select Scanner Set-up .
3. Select Scanner Speed
4. Select the required scanner speed:
• Auto
• 24 RPM
The Auto option automatically selects the appropriate speed
for your radar range. 48 RPM is used at radar ranges of up
to 3 nm. It provides an increased refresh rate, which is useful
at high speed or in areas where you have large numbers of
radar targets. At radar ranges of greater than 3 nm the display
switches the radar speed to 24 RPM.

set to ON, select this mode to activate the
scanner. This is the usual mode of operation.

This is a power-save mode used when the
radar is not needed for short time periods.

magnetron does not need to warm up again.
This is the default mode.
