INTRODUCTION > CARE INFORMATION

Care Information

To resolve problems that cannot be remedied using this guide, contact Garmin Product Support in the U.S.A. at 800/800.1020 or Garmin Europe at 44/0870.8501241.

Immersing the Unit in Water

The GPSMAP 276C is waterproof to IEC Standard 60529 IPX7. It can withstand immersion in 1 meter of water for 30 minutes. Prolonged submersion can cause damage to the unit. After submersion, wipe and air dry the unit before reuse or charging.

Cleaning the Unit

The GPSMAP 276C is constructed of high quality materials and does not require user maintenance other than cleaning. Clean the unit using a cloth dampened with a mild detergent solution. Avoid chemical cleaners and solvents that may damage plastic components. Wipe the unit dry with a dry cloth.

Storing the GPSMAP 276C

Do not store the GPSMAP 276C where prolonged exposure to temperature extremes may occur (such as in the trunk of a car), as permanent damage may result. User information, such as waypoints and routes, is retained in the unit’s memory without the need for external power. It is always a good practice to back up important user data by manually recording it or downloading it to a PC (transferring it to MapSource).

GETTING STARTED > CHARGING THE GPSMAP 276C

Charging the GPSMAP 276C

Before using the unit, you may need to charge the battery in the GPSMAP 276C. Simply plug the unit into an external power source to charge. You can use the unit while it is charging.

If you do not want to use the unit, but you would like to charge the battery, you can put the unit into Charge Mode. Connect the unit to an external power supply. Press and hold the red POWER key. Instead of completely turning off, the unit now goes into Charge Mode, as shown below.

To charge the unit’s battery:

1. Lift the rubber weather cap to expose the power connector on the back of the unit. Refer to the image on page 1 for connector location.

2. Align the notches and push the plug into the connector until fully seated.

3. Plug the 12 Volt adapter into an available AC outlet, or cigarette lighter receptacle if you have a Cigarette Lighter Adapter. Use care when routing the cable; be certain that it does not interfere with vehicle operation.

The unit begins charging as soon as external power is applied.

NOTE: While in Charge Mode, the unit draws a small amount of

GETTING STARTED > GETTING SATELLITE SIGNALS

Getting Satellite Signals

After you turn on the GPSMAP 276C, the unit automatically begins searching for satellites. The GPS page is displayed while the unit is gathering satellite signals and acquiring a ﬁx, which should take only a few minutes. While the GPSMAP 276C is getting satellite signals, the GPS page displays the status as “Acquiring Satellites.”

It may take a few minutes to acquire satellites and display your current location on the map. Be patient as the unit acquires satellite data. To get signals more quickly, be sure the antenna is raised to the up position shown in the image on page 1.

Viewing GPS Status with the GPS page

The GPS page provides a visual reference of satellite acquisition, receiver status, and accuracy. The sky view and signal strength bars give an indication of what satellites are visible to the receiver and whether they are being tracked.

As the receiver locks onto satellites, a signal strength bar appears for each satellite in view, with the appropriate satellite number underneath each bar. The numbers displayed below each bar represent the particular satellite that is being received. Numbers above 33 indicate WAAS satellites.

The sky view shows a birds-eye view of the position of each satellite relative to the receiver’s last known position. The outer circle represents the horizon (north up), the inner circle represents 45º above the horizon, and the center point represents a position directly overhead. You can also set the sky view to a Track Up conﬁguration, causing the top of the sky view to align along your current track heading. Press MENU to change the conﬁguration of the sky view.

GPS Tips

While the receiver is gathering information, your location on the map may display as different from where you actually are located. Be patient; as soon as the receiver gathers enough satellite information, your proper location is displayed on the map.

Any time you have traveled more than 600 miles with the GPS receiver turned off, the receiver may take longer than normal to initialize and ﬁnd your location.

The GPS receiver can lose satellite signals due to interference from such items as buildings, tunnels, and heavy tree cover. Monitoring

BASIC OPERATION IN MARINE MODE > CREATING AND USING WAYPOINTS

Creating and Using Waypoints

Waypoints are locations or landmarks you record and store in your GPS. They are locations you may later want to return to, such as checkpoints on a route or signiﬁcant ground features. You can add waypoints to routes and even create a Go To directly to the selected waypoint.

Save your current location as a waypoint by pressing and holding ENTER/MARK. You can also ﬁnd waypoints using the map or the Find Menu and then store them in the unit before ever leaving home.

Marking Your Present Position

The ENTER/MARK key lets you quickly capture your present position to create a new waypoint. You must have a valid position (2D or 3D) ﬁx to mark your present position. You can determine the satellite ﬁx by looking at the GPS tab on the Main Menu.

To mark your present position:

1. Press and hold the ENTER/MARK key until the New Waypoint page appears, then release it. A default four-digit name and symbol are assigned for the new waypoint.

The GPSMAP 276C stores up to 3000 alphanumeric waypoints with a user-deﬁned icon, comment, altitude, depth, and temperature available for each waypoint. Waypoints can be created using three basic methods:

• ENTER/MARK—allows you to quickly mark your present position.

• Graphically—allows you to deﬁne a new waypoint position from the map display using the Rocker key.

• Text Entry—allows you to enter a new waypoint’s position coordinates manually.

2. To accept the waypoint with the default information, use the Rocker key to highlight OK and press ENTER.

BASIC OPERATION IN MARINE MODE > MANAGING YOUR TRACKS

Managing Your Tracks

Setting up and Saving your Tracks

The GPSMAP 276C draws an electronic breadcrumb trail or “track log” on the Map page as you travel. The track log contains points along its path, including time, and position for each point.

The track log starts recording as soon as the GPSMAP 276C gets a location ﬁx. For the best results, clear the track log before you start traveling because when the track log is full, new track points overwrite the oldest track points.

The percentage of memory used by the current track log appears at the top of the Active tab. After the track log is cleared, it displays zero percent. When the display reaches 100%, the most recent track points start to overwrite the least recent track points (if Wrap is selected for Record Mode). To avoid losing track points, save the track log when it approaches the 99% mark.

You must ﬁrst save the track log before you can use the

MARINE MODE PAGES AND FEATURES > DSC

DSC

The DSC page of the Main Menu (Marine Mode only) allows you to control and set up the Digital Selective Calling (DSC) features on the GPSMAP 276C. Digital Selective Calling (DSC) uses marine VHF radio and Global Positioning System (GPS) technologies to transmit and receive location information. DSC is used by mariners for two major operations: Distress Calls and Position Reporting.

For more information about Digital Selective Calling and Maritime Mobile Service Identity (MMSI) numbers, refer to pages 113–114 in the “Appendix.”

Understanding Distress Calls

With your GPSMAP 276C properly connected to a VHF radio with DSC output, you may receive any DSC Distress Call within range. An alert message appears and a tone sounds when a Distress Call is received. The alarm only sounds on a Distress Call; Position Reports do not sound the alarm. Distress Calls are broadcast to all DSC users in radio range and appear with a blue and white checkered icon on the DSC Call List and Log tabs.

You can enter a caller’s name, if it is known. The caller’s name replaces the MMSI number as a reference once entered.

Understanding Position Reports

The Position Report operates similarly to the Distress Call. This type of contact is like a phone call; no emergency alarms are set off. Position Reports are not broadcast to all DSC users and appear with a gold boat icon.

Receiving DSC Calls

Each time you receive a Distress Call or Position Report, a review page opens—either a DSC Position Report page or a Distress Call page. Both pages contain identical ﬁelds to the DSC Entry Review page shown below.

DSC Call List

The Call List displays the 50 most recent calls, even if the unit is left unattended. The Call List only displays the most recent call from a vessel. If a second call is received, it replaces the ﬁrst call in the Call List. Press MENU to sort the list and delete entries.

Each entry in the Call List and Log has a corresponding DSC Entry Review page. This page operates similarly to the Distress Page and Position Report Page. From the DSC Entry Review, you can Delete the entry, Save it as a waypoint, or show the location on the map.

To review a call or log entry:

1. Open the Call List or Log from the DSC tab.

2. Press Up or Down on the Rocker keypad to highlight the call you want to review.

3. Press ENTER to open the DSC Entry Review page.

After creating a New Directory Item, the name created is attached to that particular MMSI number. If you return to the Log, the new name is displayed under the corresponding MMSI number.

Another way to input a name is from the Entry Review page or the DSC Distress Call or DSC Position Report pages. The Name and MMSI are sent to other Garmin GPS units: Only the MMSI numbers are sent to other non-Garmin DSC users.

Making a Distress Call

To make a Distress Call, press the MayDay button on your VHF radio. The call transmits on an emergency channel with the MMSI number attached to the call, if you have DSC support. Any DSCequipped mariner (on sea or land) within range can receive the call.

SETTING UP AND USING SONAR > USING THE SONAR PAGE

Using the Sonar Page

When combined with a GSD 20 Sounder Module, your GPSMAP 276C becomes a powerful ﬁshﬁnder/ﬂasher with the Sonar page. If a GSD 20 is attached, but the unit does not detect a transducer, a “Sonar Turned Off” message appears across the Sonar page. If a GSD 20 is not attached, the Sonar page only appears when the unit is in Simulator Mode.

The sonar returns show as red (strongest), then oranges (strong), yellows (medium), greens (weaker), and blues (weakest). The Fish Symbols option allows you to view the actual sonar data, a ﬁsh symbol or a combination of both. When the unit is set to Dual, the appearance of the ﬁsh symbols changes. Fish symbols from the center of the beam (200 kHz) are solid (or narrow arches), but the returns from the edges of the beam (50 kHz) are hollow (or wide arches).

The middle of the page contains a right-to-left moving sonar image of the water beneath your boat. Items appear as they pass under your transducer. Those items on the right side of the screen are closer to you than those on the left. Along the right side of the screen is an adjustable scale that reﬂects the depth of the area being displayed. The top left corner displays the Adjustment Option, the depth, and the water temperature.

The sonar display may also be set to show a split screen view of a zoomed portion of the sonar, bottom lock (display scaled from the bottom up), or a combination of these options. For example, you may choose to show dual frequency at a 2X zoom (Dual 2X) on one half and normal range dual frequency (Dual) on the other half. The current display mode is displayed at the bottom of each sonar display.
