Main Pages Using the Electronic Compass When you press and hold PAGE on these units, the electronic compass turns off and stays off until you press and hold PAGE again. The electronic compass functions like a magnetic compass when you are stationary. When you are moving and reach a pre-set speed, it uses data from the GPS receiver to maintain your heading. When you stop (after a pre-set time), it again operates like a magnetic compass. To turn the electronic compass on or off: 1. Press and hold the PAGE key to turn the electronic compass on or off. The Compass icon appears in the status bar when the electronic compass is on. When you are not using the electronic compass, turn it off to conserve batteries. When it is turned off, the unit uses the GPS receiver for navigation. 2. Hold the GPSMAP 76CSx level to get an accurate electronic compass reading. Setting the speed and time for Compass Auto On/Off: 1. Press MENU twice to open the Main Menu. 2. Highlight Setup, and press ENTER to open the Setup Menu. 3.

Calibrating the Electronic Compass Calibrate the electronic compass outdoors when you first use the GPSMAP 76CSx. To ensure continued accuracy, calibrate after installing new batteries, after moving more than 100 miles (160 km), or experiencing a temperature change greater than 68º F (20º C) from the last calibration. The accuracy of the electronic compass is also adversely affected if the unit is not held level or you are near objects that affect magnetic fields, such as cars or buildings.

The bearing pointer indicates the direction to your destination, and the course pointer indicates your relationship to a course line leading to the destination. If the bearing pointer arrow is pointing straight up, for example, you are going directly to your destination. If it points any direction other than up, turn toward that direction until the arrow is pointing up and then continue in that direction. The bearing pointer points to the destination.

Lift the USB protective cover from the back of the GPSMAP 76CSx and insert the smaller connector on the USB cable into the matching port. 2. Connect the remaining cable end to your computer's USB port. To connect to your computer using a Serial Port connector: 1. Lift the Serial Port protective cover from the back of the GPSMAP 76CSx and insert the round indexed connector on the cable into the matching port. 2. Connect the remaining cable end to your PC Serial port or other appropriate device. 3. Set your GPSMAP 76CSx interface setting to the appropriate interface format.

Appendix Caring for the GPSMAP 76CSx The GPSMAP 76CSx case is constructed of high quality materials and does not require user maintenance except cleaning. Cleaning the Case Clean the unit’s outer casing (except for the screen) using a cloth dampened with a mild detergent solution and then wipe dry. Avoid chemical cleaners and solvents that may damage plastic components. Cleaning the Screen The unit’s lens is coated with a special anti-reflective coating that is sensitive to skin oils, waxes and abrasive cleaners. Cleaners containing ammonia, alcohol, abrasives, or anti-grease detergents will harm the anti-reflective coating. It is important to clean the lens using an eyeglass lens cleaner (that is specified as safe for anti-reflective coatings) and a clean, lint-free cloth. Storage Do not store the GPSMAP 76CSx 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 are 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 computer (transferring it to MapSource). Water Immersion The unit 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, be certain to wipe and air dry the unit before reuse.
