associated with an MMSI.

Database Error

—internal problem with the unit. Contact your

dealer or Garmin Product Support to have the unit serviced.

directory has reached the maximum of 100 contacts. Delete

unneeded contacts to add new ones.

Distress Call

—a DSC distress call has been received. Take

appropriate action.

temperature is 2°F (1.1°C) above or below the temperature specied

by the Water Temperature Alarm. These messages appear when you

enter or leave that zone.

Entering Safe Region—the boat is approaching a safe region as

dened by your conguration settings.

Entering Unsafe Region—the boat is approaching an unsafe region

as dened by your conguration settings.

Lost Satellite Reception—the unit has lost satellite signals. Check

antenna connections or try moving to a location with a clear view of

the sky.

NMEA Depth Is Below Transducer

—you must enter an

appropriate Keel Offset for the transducer (page 43).

GPSMAP 400/500 Series Owner’s Manual 59

Appendix

No Waypoints/Routes/Tracks/User Waypoints Found—attempted

to transfer user data from an SD card that does not contain the

specied type of data. Make sure there is data to transfer on the SD

card.

Off Course Alarm

—you are off course the distance set in the “Off

Course” alarm.

Route Already Exists

—you entered a route name that already exists

in memory. Modify the route name or delete the previous route

name.

Route Full

—you attempted to add more than 250 points to a route.

Reduce the number of points or create a second route.

Route Truncated—an uploaded route from another device has more

than 250 waypoints and was truncated to t.

Route Waypoint Memory Full

—no additional route waypoints can

be saved.

Shallow Water Alarm

—the Shallow Water Alarm depth has been

reached.

Sonar Service Incompatible

—the external sonar device you are

connected to needs a software update.

Sonar Timeout—there is an internal problem with the unit. Contact

your dealer or Garmin Product Support to have the unit serviced.

Sonar Service Lost—the external sonar device you were connected

to has either been disconnected or the unit has lost communication

with the sonar device for some other reason.

Track Already Exists [Track Name]

—you entered a saved track

name that already exists in memory. Modify the track name or delete

the existing track.

Track Log Full

—the track log is full and track recording has been

turned off. To record more track points, you need to clear the track

log and turn track recording on. This only appears when the track

recording setting is set to “Stop When Full.”

Track Memory is Full, Can’t Create Track

—the track log

memory is full. No additional track log data can be stored without

deleting old data to create memory space.

Track Truncated—a complete uploaded track does not t into

memory. The oldest track log points were deleted to make space for

the most recent data.

Transducer Disconnected, Sonar Turned Off

—there is not

a transducer attached, there is a bad cable or transducer, or the

transducer cable was disconnected. If the transducer cable is

removed while the unit is on, reconnect and cycle power.

Transfer Complete—the unit has nished uploading or

downloading information to the connected device.

user data without an SD card containing user data being present in

the SD card slot.

Warning: Auto-guidance route starting and ending position

moved due to safe depth settings—the auto-guidance route was

calculated but the starting and ending positions were moved because

of safe depth settings.

Water Speed Sensor Is Not Working

—the speed sensor is not

detected. Check the connections.

Water Temperature Alarm

—sonar has reported a temperature

above, below, inside, or outside the specied values.

Capturing Screenshots

You can capture a screenshot of any screen displayed on your unit as

a bitmap (.BMP) le and then transfer it to your computer.

To capture screenshots:

1. Insert an SD card into the SD card slot on the front of the unit.

2. Select Congure > System > Beeper/Display.

3. Select Screenshot Capture to turn screenshot captures On.

4. When you are on a screen you want to capture, press and hold

the HOME button for at least six seconds.

5. Select OK when the Screenshot Taken window is displayed.

To copy the screenshots to your computer:

1. Remove the SD card from the chartplotter and insert it into an SD

card reader that is attached to a computer.

2. From Windows Explorer, open the Garmin\scrn folder on the SD

card.

3. Copy the appropriate .BMP le on the card and paste it to any

location on the computer.

Caring for the Unit

The 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.

GPSMAP 400/500 Series Owner’s Manual 61

Appendix

Cleaning the Screen

The lens on the screen is coated with a special anti-reective coating

that is sensitive to skin oils, waxes, and abrasive cleaners. Cleaners

containing ammonia, alcohol, abrasives, or anti-grease detergents

will harm the anti-reective coating. It is important to clean the lens

using an eyeglass lens cleaner (that is specied as safe for anti-

reective coatings) and a clean, lint-free cloth.

NMEA 2000

The following GPSMAP 400 and GPSMAP 500 series chartplotters

are NMEA 2000 certied and can receive data from a NMEA 2000

network installed on the boat.

GPSMAP 421/421s GPSMAP 521/521s

GPSMAP 451/451s GPSMAP 526/526s

GPSMAP 551/551s GPSMAP 556/556s

To connect one of these chartplotter to an existing NMEA 2000

network and to see a list of supported NMEA 2000 PGN numbers,

see the GPSMAP 400/500 Series Installation Instructions.
