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 > 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.
