Staying On Course

As you travel the route, staying on the track line is the most efficient way to get to your
destination. The Cross Track Error indicator on the numeric or the digital readout provides a
precise indication of distance from the track line.
If the Off- Course alarm is on, alarm boundaries are drawn on the map to indicate the alarm
settings. If the Cross Track Error exceeds the Off- Course alarm setting, the alarm will sound. The
factory setting for Off- Course alarm is .1nm. This can be adjusted to maintain a more precise
course (see "Using the Menu System – Alarms" for more information).

Arrival Alarm

If the Arrival alarm is on, an alarm boundary is drawn around the current destination waypoint.
When the Distance To Go (DTG) to the Waypoint is less than the alarm setting, the alarm will
sound. The factory setting for the Arrival Alarm is .1nm. This can be adjusted manually (see
"Using the Menu System – Alarms" – for mire information.
Waypoint Sequencing as you move beyond a destination waypoint within the route, the NS25
automatically "sequences" to the next waypoint providing new navigation information.
At times, the NS25 may not be able to determine when to automatically sequence to the next
waypoint. When this occurs, a menu displays to permit manual sequencing.

Modifying a Route While Traveling

While traveling a route, you can modify it as you go. You may add waypoints to the end or middle,
replace the current waypoint, skip waypoints, or redirect the route entirely.
To skip a waypoint or series of waypoints, use the cursor to highlight the waypoint within the route
that you want to go to, then press GOTO. A men appears to confirm. Select Yes to skip to the
new waypoint. The track line redraws your route with updated information.
To make other modifications, use the cursor to highlight a waypoint you wish to change, then
press GOTO. A menu displays the options for the highlighted waypoint.
