4-8 Raychart 425 Chartplotter
Waypoint Symbol
This option allows selection of the symbol for waypoint display. The
selected symbol is used for subsequent waypoints. Existing waypoints
are not affected. The selected symbol is retained when the unit switched
off.
Autozoom
When autozoom is enabled, commencing any navigation function or
selecting
FIND SHIP activates Autozoom. When active, this selects the
chart range and position such that the vessel and the target waypoint are
both on screen but at the largest scale possible. Moving the cursor off the
vessel, or changing scale, deactivates Autozoom.
Autozoom will not zoom in beyond the largest cartographic scale (unless
Plotter Mode is activated). When in
MOB mode, Autozoom is selected
automatically and will zoom in as far as possible, irrespective of the
selection of Plotter Mode.
Screen Amplifier
Screen amplifier mode makes best use of the screen by positioning the
vessel on the screen so as to increase forward visibility. The screen
amplifier is only active when the cursor is ‘homed’ on the vessel.
COG Vector
When ON, a vector line from the vessel is drawn in the direction of COG.
This line extends to the edge of the screen. If COG is not valid, no line is
drawn. The selected setting is retained when the unit switched off.
Arrival Circle
The selected value is used as the arrival circle radius. When approaching
the target waypoint, this is the distance at which the arrival alarm sounds.
The selected setting is retained when unit switched off. Arrival criteria
are met when the arrival circle is entered or a line perpendicular to the
desired track and passing through the waypoint is crossed.
Anchor Alarm
The selected value is used as the anchor alarm distance. If the vessel
moves outside of the selected distance from its position (at the time that
the alarm was enabled) the alarm sounds and an alarm message is
displayed.
