The case is constructed of high-quality materials and does not require user 

maintenance, except cleaning.

Clean the unit’s outer casing using a cloth dampened with a mild detergent 

solution and then wipe dry. Avoid chemical cleaners and solvents that may 

damage plastic components.

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.

Do not store the unit where exposure to temperature extremes may occur, as 

permanent damage may result. 

The Garmin GDL 30/30A has no user-serviceable parts. Should you ever 

encounter a problem with your unit, take it to an authorized Garmin dealer for 

repairs or contact Garmin Product Support.
The GDL 30/30A is fastened shut with screws. Any attempt to open the case 

to change or modify the unit in any way voids your warranty and may result in 

permanent damage to the equipment.
