16.15 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.

Follow the steps below to change the radar speed.
The speed option requires a 48 RPM compatible
Raymarine HD radome or Raymarine SuperHD open
array radar scanner.

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.
