GDL 30/30A Owner’s Manual

Product Safety and Regulatory Information

The GPS system is operated by the United States government, which is solely

responsible for its accuracy and maintenance. The system is subject to changes

which could affect the accuracy and performance of all GPS equipment. Although

the Garmin GDL 30/30A is a precision electronic NAVigation AID (NAVAID),

any NAVAID can be misused or misinterpreted and, therefore, become unsafe.
The electronic chart is an aid to navigation and is designed to facilitate the use of

authorized government charts, not replace them. Only official government charts

and notices to mariners contain all information needed for safe navigation. As

always, the user is responsible for prudent use of this information.
Use the GDL 30/30A at your own risk. To reduce the risk of unsafe operation,

carefully review and understand all aspects of this Owner’s Manual. If necessary,

thoroughly practice operation using the simulator mode prior to actual use.

When in actual use, carefully compare indications from the unit to all available

navigation sources, including the information from other NAVAIDs, visual

sightings, and charts. For safety, always resolve any discrepancies before

continuing navigation.

Weather and Sea Surface information

The GDL 30/30A receives XM Weather Radio data and shows it on your

chartplotter. The weather data for each feature comes from reputable weather

data centers such as the National Weather Service and the Hydrometerological

Prediction Center. (See the XM WX Satellite Weather Web site at

http://weather.

xmradio.com/weather

for more information.) Any weather feature can change in

appearance or interpretation if the source that provides the information changes.

XM Weather Radio data is broadcast at set rates (see

page 24

for all weather-

related broadcast rates). For example, NEXRAD Radar data is broadcast at five

minute intervals. When the marine network is turned on or when a new feature

is selected, the GDL 30/30A has to receive new data before it can be displayed.

For this reason you may experience a delay before weather data or a new feature

appears on the map.
