If the active GRI Chain, secondary stations, or offsets were changed since the
waypoint was created, the waypoint now references the active GRI-chain and
secondary stations and adjusts the TD coordinates accordingly. Remember that
the GPS is not relying on the LORAN signal for navigation and actually converts
the TD coordinate to a useful latitude/longitude coordinate (in the background)
before storing the waypoint to memory or using it for navigation. Because of this,
the unit can navigate to a TD coordinate anywhere in the world.
For more information on LORAN TDs, you can download Garmin’s Loran TD
Position Format Handbook from the Garmin Web site.
Caring for the GPSMAP 3006C/3010C
The GPSMAP 3006C/3010C 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. Wipe dry. Avoid chemical cleaners and solvents that
may damage plastic components.
Cleaning the Screen
The GPSMAP 3006C/3010C 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 3006C/3010C where prolonged exposure to extreme
temperatures may occur (such as in the trunk of a car) because 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, loading it to a computer
(transferring it to MapSource), or storing it on a data card.
Water Immersion
The GPSMAP 3006C/3010C 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.
