3. To select a waypoint from the waypoint lists, use the ROCKER to highlight either the By Name or Nearest tab, select a waypoint, and press ENTER.

Selecting a Go To Graphically

A Go To can be used to select one of three items from the Map Page: an existing waypoint, an on-screen map item such as roads, rivers, cities, and navaids, or a new map point. If you are selecting a map item as the Go To destination, the GPSMAP 392/398/492/498 automatically uses the name of the map item, but the point is not stored in the waypoint list. See page

8 for creating waypoints using map items. If you are selecting

a new map point (non-map item) as the Go To destination, the GPSMAP 392/398/492/498 automatically creates a waypoint at the map pointer location.

TracBack Navigation (Navigating a Track)

The TracBack function retraces your path to the starting point using the track log automatically stored in the receiver’s memory. This feature eliminates the need to store waypoints along the way. TracBack routes are created by reducing your track log into a route of up to 300 turns and activating an inverted route along those points. When started, a TracBack route leads you back to the oldest stored track log point, so it is a good idea to clear the existing track log before you start your current trip.

Following a Track

The Following a Track function retraces a track from the

beginning, the oldest time, to the end, the newest time. You can

only use this function with Saved Tracks. To save a track, refer to

• Always clear the track log at the starting point. the instructions on page 15.

• Set the Record Mode option on the track log setup page to

Fill or Wrap.

• The track log memory must contain at least two points to

create a TracBack route.

• If the track log interval is set to the Time

option, the route can not follow your exact path. For best performance, keep the interval set to Resolution.

• If the receiver is turned off or satellite coverage is lost during your trip, the TracBack draws a straight line between any point where coverage was lost and where it resumed.

• If the track log’s changes in distance and direction are too complex, 300 waypoints might not mark your path accurately. The receiver then assigns the 300 waypoints to the most signiﬁcant points of your track, and simpliﬁes segments with fewer changes in direction.

To Follow a Track:

1. Press NAV, highlight Follow Track, and press ENTER.

DSC (Digital Selective Calling)

The DSC tab controls and sets up the DSC features on the GPSMAP 392/398/492/498.

DSC uses marine VHF radio and GPS technologies to transmit and receive location information. The chartplotter repeats the call properties received from the VHF radio on the chartplotter. The GPSMAP 392/398/492/498 requires input from a DSC-enabled VHF radio to show position, and sound/show alerts from a distress call or position report. Conversely, the VHF radio requires input from a GPS to transmit position coordinates for a distress call or position report. For connection information, refer to “Connecting the Power/Data Cable” on page 92.

call, they can immediately access the caller’s information (such as who they are and the type of vessel) in their database while they are in transit to the caller’s location.

A non-emergency DSC position report allows mariners to exchange and show the positions of one another. When a DSC position is received, the mariner can choose to create a waypoint or to show the received location on an electronic map.

Anytime a vessel receives a DSC call, they can store and quickly navigate to that location using a Go To. In order to use DSC, users must ﬁrst register their VHF radio with the FCC and receive a Maritime Mobile Service Identity (MMSI) number. Garmin does not provide MMSI numbers.

For more information about Digital Selective Calling and Maritime Mobile Service Identity (MMSI) numbers, refer to page 97 in the “Appendix.”

Understanding Distress Calls

When the GPSMAP 392/398/492/498 receives a distress call from a connected DSC-enabled VHF radio, an alert message and notiﬁcation page are shown, and an alarm tone is sounded. Distress Calls are shown in the DSC Call List and Log with a checkered

symbol .

Understanding Position Reports

A position report is similar to a distress call except no alarm is sounded. Position reports are not broadcast to all DSC users and are shown with a boat symbol .

Receiving DSC Calls

Each time you receive a distress call or position report, a Notiﬁcation Page is shown, and the call is placed in the DSC Call List and Log. The Notiﬁcation Page contains information about the call including: the type of call (distress or position report), the MMSI number of the caller, a user deﬁnable name, the time and date of the call, the bearing and distance from your current location, and the coordinates of the caller. To see the caller’s location on a map, select the Show Map button. To create a waypoint at the caller’s location, select the Create Wpt button. To close the Notiﬁcation Page, press QUIT.
