Autozoom will not zoom in beyond the largest cartographic scale (see also Plotter Mode). When in MOB mode, Autozoom is selected automatically and will zoom in as far as possible, irrespective of the selection of Plotter Mode.

Unless MOB is active Autozoom will not be activated if there is no cartridge or if the area being viewed is not covered by the cartridge.

Screen amplifier

Screen amplifier mode makes better 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.

To silence the alarm, press any key. This removes the warning and resets the distance, ie. the alarm will not sound again unless the vessel moves the selected distance from its position (at the time that the alarm was silenced). The alarm is set to OFF on power up.

XTE alarm

The selected value is used as the cross track error limit. The alarm sounds when the cross track error exceeds the selected limit when a GOTO or a Route Follow is in progress and an alarm message is displayed.

Chart text

When ON, Chart text, eg. place names are shown on the screen. The selected setting is retained when the unit switched off.
