Grid - on chart can be set to AUTO / ON / OFF.
ON = the grid is always visible on the chart display.
OFF = the grid is turned off and will not show on the chart display.
AUTO = the grid will not appear in the ordinary chart display, but will be there
when in overzoom and when “Chart” is turned off in the Chart setup, which
means that there will be no World chart presented and no C-MAP charts
presented – only user-made data such as waypoints, routes, lines and tracks, etc.
Heading – the direction of which the vessel is pointing.
Lock cursors – will lock the cursors in two chart displays on the same screen
and thus make the cursor movements synchronized. When moving the cursor to
search for e.g. a harbor in one chart (large scale), the other chart (small scale)
will automatically follow and thus reveal the details. This process is very
demanding and may take some seconds extra for updating.
LOG speed calibration – the unit is preset to receive 19000 pulses per nautical
mile from the log transducer (paddle wheel). However the figure might have to
be changed to compensate for various transducers and actual water flow passing
the transducer. The correct pulse rate is calculated by:
19000 x indicated speed (e.g. 4kn) = 15.200 pulses/nm
actual speed (GPS) (e.g. 5kn)
Measurement units – the user may select the displayed units to be one of the
following: m meters
ft feet
fm fathoms
nm nautical mile, 1 nm is 1,852 meters
kn knots, nautical mile per hour
km kilometer, 1 km is 1,000 meters
kh kilometer per hour
mi statute mile, 1 mile is 1,609 meters
mh mile per hour
MENU – the selection of main menus will be shown in the upper part of the
screen. Leaf through the menus by means of the cursor key and the [ENT] key, or
use the numerical keys to activate one of the menus.
