Chapter 11: Using the Radar (HD and SuperHD Digital)
Note:
The RayTech radar functions require a connection to a SeaTalk
hs
network that includes a compatible Raymarine radar scanner AND a
compatible Raymarine multifunctional display. The multifunction
display must be designated as the data master.
Digital scanners offer:
Improved target definition.
Full-color image.
SuperHD option. SuperHD effectively increases the transmitter
power by a factor of at least two, and reduces the beamwidth by a
similar amount. (
You require a SuperHD radar for the SuperHD
options to function
).
Note:
The radar needs to be receiving heading and position data for full
functionality.
11.1 Radar setup
The Radar Setup Menu lets you customize the way the radar operates.
Changes you make in this menu are kept when you remove power from the
system.
Select scanner
Selects which scanner is displayed in active radar windows.
Scanner setup
The scanner setup option lets you customize various aspects of the
scanner’s behavior, such as the ‘Edit Name’ softkey, which allows you to
name individual scanners.
Short range:
Short range gives a maximum range of 3 nautical miles.
Long range
Long range provides more standard ranges. It is not possible for the long
range to be set to a range less than the short range i.e. if Short range =
3Nm then Long range cannot be less than 3Nm.
Note:
There is no short range operation for Super High Definition
(SuperHD) radars.
Tune adjust
The tune adjust function is used to fine-tune the scanner’s receiver for
maximum target returns on the display, though we recommend that you
use the automatic settings.
Auto mode: (recommended)
In AUTO mode, the radar tunes itself automatically on all range scales.
This is the default mode and it is recommended that you leave the tune
function in auto mode to ensure that the radar receiver is always tuned to
receive the maximum signal.
Manual mode
If you do set the tune function to MANUAL, you will need to adjust it about
10 minutes after you have turned on the radar, as the required setting will
change after the magnetron has warmed up.
Adjust the control to obtain the maximum signal strength (indicated by the
eight-step horizontal bar). If you cannot tune the radar successfully, refer to
the Installation Guide or return the radar to Auto made.
