CA34/44/54 Radar menu
The guard zone is not available in the secondary radar display in
Dual Radar mode.
IR
(Interference Rejection) – will reduce false echoes from other
radars nearby, see section 3.1.10.
Stretch
– toggle between AUTO, ON, OFF.
AUTO (default) - small targets are enhanced at ranges above 12 nm.
ON - all targets will be enhanced.
OFF - all targets will remain unchanged.
Rpm
– will determine the scanner rotation (full screen presentation).
Manually, the rotation speed can be set to either 24 or *48 rpm,
depending on the scanner type (use +/- keys).
*Running 48 rpm (double update rate) is liable to reduce the lifetime
of the mechanical parts.
HDG
– your heading will be shown (full screen presentation) in
degrees from connected compass. If no compass is connected, you can
use the course (COG) from the built-in GPS module by changing “Use
COG as internal heading” from NO to YES in the interface setup.
Press [MENU], [7], [2], and then press [PLOT] repeatedly until the
tab reads Compass.
When using the GPS course as replacement for heading input, the
accuracy will be reduced in relation to speed, wind and current.
Pulse
- can be set to SHORT, NORMAL or LONG.
NORMAL (default) will not change the presentation of targets.
SHORT - (press the [-] key to access) will enhance target resolu-
tion at range 0.5-6.0 nm. However, this setting may result in making
some smaller targets disappear.
LONG - (press the [+] key to access) will enlarge targets on screen
and improve target detection. However, this setting will also enlarge
any noise picked up.
Depth
- readout in meters, feet or fathoms from built-in echosounder
function or external depth source.
