16.2 Radar scan speed

SuperHD open array radars with software version 3.23 or above
or HD 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 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 scan speed
The speed option requires a 48 RPM compatible Raymarine HD
radome or Raymarine SuperHD 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.
