How To Select Options and Enter Data
Getting Started Selecting Options
Before moving ahead into GPSMAP 168 features, you will need to learn basic operation. You can select and activate options and enter data to customize the GPSMAP 168 to t your requirements. You can use the ENTER/MARK key and ARROW KEYPAD to select options, enter names and numbers in data elds, and activate your selections.
To select and activate an optional feature:
1. With any page displayed, press the MENU key to pop-up the options menu. The options menu will display a list of optional features which are specic for that particular page. To select any feature on the list of options requires movement of the cursor, which is identied as highlighting, selecting or choosing an item in a list or a eld (box) on a page. 2. Use the ARROW KEYPAD to move the cursor (highlight) up and down a list or up, down, and sideways on menus.

The GPSMAP 168 Sounder does not track satellites in simulator mode, and this mode should never be used for actual navigation.
When the unit is in simulator mode, an S will appear in the lower left corner of every screen and the Status Page will show Simulating Navigation.
All the waypoint and route planning done in simulator mode will still be retained in memory for future use.

168 Manual Part 1.indd 7

Getting Started Status Page/Map Page
The Status Page is one of six main pages used in the GPSMAP 168 Sounders system. The six main pages are: the Status Page, Sonar Page, Map Page, Compass Page, Highway Page and Active Route Page. All six pages are linked together in a simple chain, which allows you to scroll through the pages in either direction using the PAGE and QUIT keys.

Status Page

Sonar Page

Map Page

Compass Page

Highway Page

Active Route Page
To continue the tour, lets move on to the next page, the Map Page. To scroll to the next page in sequence:

1. Press the PAGE key.

The GPSMAP 168 Sounders Map Page combines digital chartplotting with a user-selectable display of navigation data and a built-in worldwide database to 20 mi. It will also be the page you use most to create and edit waypoints and routes. Before we take off on our practice route, lets take a brief look at its various features and displays. The map display shows your boat as a triangle marker on an electronically generated chart. Geographic names, roads, markers and buoys that are provided by the optional MapSource data are also shown. It also displays your track, routes and nearby waypoints. An on-screen cursor lets you pan to other map areas, determine the range and bearing to a position, and perform various waypoint and route functions. The data window, located at the top of the page, provides a user-selectable display of various navigation data, including course, speed over ground, and bearing and distance to the cursor or a particular waypoint. The current map scale setting is located at the bottom right of the page.

168 Manual Part 1.indd 8

Using the Map Cursor
Working from the Map Page is a simple process that centers around the use of the cursor. Controlled by the ARROW KEYPAD, the cursor is an important tool that can be used to pan to other map locations, mark and edit waypoints and routes, and review position data of on-screen map items and waypoints. To get a feel for using the Map Page and using the cursor, try the following exercise:
1. Use the IN/OUT keys to set the map scale to the 50 nm setting. Your boat should be near the center of the map, at the receivers last known position. (If your boat isnt where it should be, make sure that you have initialized the receiver and acquired a position as described on pages 1-2.) 2. Use the ARROW KEYPAD to move the cursor. Notice how another data eld appears at the top of the page, showing the bearing and distance from your boat to the cursor, along with the latitude/longitude of the cursor. 3. Press the QUIT key to remove the cursor and re-center your boat on the map display.

Lets move on to the Highway Page by pressing the PAGE key.
168 Manual Part 1.indd 16
The GPSMAP 168 Sounders Highway Page also provides graphic steering guidance to a destination waypoint. As you head toward your destination, the middle of the screen provides visual guidance to your waypoint on a moving graphic highway. Your present position is at the bottom center of the highway display. The line down the middle of the highway represents your desired course. As you navigate toward a waypoint, the highway will actually moveindicating the direction youre off course. To stay on course, simply steer toward the center of the highway or keep it on the road. The six default data elds at the top of the page indicate Speed, Distance To your destination (or the next waypoint in a route), To Course (which shows the bearing to get you back on course), the distance you are Off Course, Time To the Next waypoint, and the compass Track you are heading. Use the Highway Page as your primary navigation page (in lieu of the Compass Page) when your main concern is following a dened course. When the GPSMAP 168 Sounder is in simulator mode, you can also adjust your speed and course from the Highway Page using the ARROW KEYPAD. As you head toward each waypoint in the tour route, try adjusting your boat speed and course to get a feel for how the highway works. To adjust the simulated boat speed from the Highway Page:
1. Press the UP arrow of the ARROW KEYPAD to increase the speed in 10 knot/kph/mph increments. Press the DOWN arrow to decrease the speed in the same increments.

Loran TD System
Loran C is a radio navigation aid operated and maintained in the United States by the United States Coast Guard. The name LORAN is an acronym for LOng RAnge Navigation. The Loran system covers the entire United States and the U.S. Coastal Conuence Zone. From the perspective of a mariner, the system is used for ocean and coastal navigation. It can be used as a supplemental system for harbor and harbor approach navigation, and it is used for inland navigation by recreational vehicles. Loran TD Feature The Loran TD (Time Delay) feature eases the transition from using Loran to using GPS. The GPSMAP unit automatically converts GPS coordinates to Loran TDs for those who have a collection of Loran xes for favorite shing spots and other waypoints recorded as TDs. You can display your position as a TD or enter waypoints as TDs. The accuracy to be expected from this conversion is approximately 30 meters. When the unit is placed in the Loran TD format mode, it simulates the operation of a Loran receiver. Position coordinates may be displayed as TDs, and all navigation functions may be used as if the unit was actually receiving Loran signals.
