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 offi cial 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 under-
stand 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 naviga-
tion sources, including the information from other NAVAIDs, visual sightings, and charts. For safety, always
resolve any discrepancies before continuing navigation.
FCC Compliance
The GDL 30/30A complies with Part 15 of the FCC interference limits for Class B digital devices FOR
HOME OR OFFICE USE. These limits are designed to provide more reasonable protection against harmful
interference in a residential installation, and are more stringent than “outdoor” requirements.
Operation of this device is subject to the following conditions: (1) This device may not cause harm-
ful interference, and (2) this device must accept any interference received, including interference that may
cause undesired operation. This equipment generates, uses, and can radiate radio frequency energy and, if
not installed and used in accordance with the instructions, may cause harmful interference to radio com-
munications. However, there is no guarantee that interference will not occur in a particular installation. If
this equipment does cause harmful interference to radio or television reception, which can be determined by
turning the equipment off and on, you are encouraged to try to correct the interference by one of the follow-
ing measures: Reorient or relocate the receiving antenna; increase the separation between the equipment and
the receiver; connect the equipment into an outlet on a circuit different from that to which the receiver is
connected; consult your Garmin dealer or an experienced radio/TV technician for help.
