83 Follow these tips to get the best performance from your camera: • Your GoPro is waterproof to 33ft (10m)—no housing needed. Be sure the door is closed before using it in or around water, dirt, or sand. • Before closing the door, be sure the seal is free of debris. Use a cloth to clean the seal if needed. • Make sure your GoPro is dry and clean before opening the door. Rinse your camera with fresh water and dry it with a cloth if needed. • If sand or debris hardens around the door, soak your camera in warm tap water for 15 minutes and then rinse thoroughly to remove the debris before opening the doors. • For the best audio performance, shake your camera or blow on the mic to remove water and debris from the microphone holes. Do not use compressed air to blow into the mic holes. This could damage the internal waterproof membranes. • After every use in salt water, rinse your camera with fresh water, and dry it with a soft cloth. • The lens cover is made from extremely tough strengthened glass, but it can still be scratched or cracked. Keep it clean with a soft, lint-free cloth. • If debris gets stuck between the lens and trim ring, fush it out with water or air. Do not insert foreign objects around the lens. Maintenance
