721 VHF radio).

Alarm status - Shows the symbol for each

alarm that is on. The symbol is normally

black and turns red if the alarm triggers.

Attention Area - An important area on a

chart, such as a restricted anchorage or a

shallow area.

AIS - Automatic Identication System. A

System where vessel information (location,

course, speed, etc.) is broadcast by VHF

radio, for use by other vessels in navigation

and collision avoidance.

Bathymetric line - A depth contour line

on the chart.

Chart card - A plug-in card that stores chart

data for a region.

C-MAP™ chart card / C-MAP™ user card - A

plug-in card that stores waypoints, routes

and tracks.

CPA - Closest Point of Approach. The closest

distance two vessels will come to each other

based on their current course and speed.

Cursor - A

symbol on the display.

DTN - Distance to the next position the

NX40/45 is navigating to, either a waypoint

or the cursor.

Fish forecaster - An estimate of the likelihood

of catching sh based on barometric

pressure. The more shes that show the

higher the likelihood (requires Simrad 721

VHF radio).

Gear - The gear the engine is in (requires

SmartCraft).

Goto - A simple way of navigating straight

to a waypoint or to the cursor position.

GPS - Global Positioning System. A satellite-

based navigation tool.

Leg - The straight segments of a route

between waypoints. A route with four

for use in Digital Selective Calling.

MOB - Man overboard.

MOB function - Starts navigating back to

the place where someone fell overboard.

NMEA - National Marine Electronics

Range rings - Concentric circles extending

from your boat (usually at the center of

the radar window) and used to estimate

distances to objects. The scale is shown in

the top left corner of the radar window.

Route - Two or more waypoints linked in

sequence to form a course for the boat.

Simnet - Communications protocol

accessing NMEA 2000 standards.

SmartCraft - A feature of Mercury

Marine engines for monitoring engine

performance.

TCPA - Time to Closest Point of Approach.

Time until the closest point of approach for

two vessels.

Sounder status - A summary of echosounder

settings.

TTN - Time to the next position the NX40/45

is navigating to, either a waypoint or the

cursor.

UTC - Universal Time Coordinated or

Coordinated Universal Time, which is

a standard world time, formerly called

Greenwich Mean Time (GMT).

VHF - Very High Frequency. The frequency

range used by marine radios and AIS.

Waypoint - A position that you can set on

the Unit chart, for example a shing spot or

a point on a route.

Weather - An estimate of the weather based

on barometric pressure.
