3. Setup and Card Insertion
- Opening the Case: Locate the snap closure on the side of the case. Gently lift the latch to open the case.

Carefully align your Micro SD card with a slot and gently push it down until it is seated securely within the foam. Ensure the card is fully inserted and flush with the foam surface.

4. Operation and Card Removal
- Accessing Cards: To retrieve a card, open the snap closure as described in the setup section.
- Removing Micro SD Cards: Gently press down on one edge of the Micro SD card within its slot. The card should slightly tilt, allowing you to grasp the opposite edge and pull it out. Avoid forcing the card to prevent damage to the card or the foam.
- Using the Lanyard: If desired, attach a lanyard to the molded eyelet on the case for convenient carrying. This helps prevent accidental drops and keeps the case accessible.

5. Maintenance and Care
- Cleaning the Exterior: Wipe the exterior of the case with a soft, damp cloth. Avoid abrasive cleaners or solvents that could damage the ABS material.
- Cleaning the Interior: If the EVA foam interior requires cleaning, use a dry, soft brush or a can of compressed air to remove dust or debris. Do not use liquids on the foam.
- Maintaining the Seal: Periodically inspect the silicone O-ring seal for any signs of wear or damage. Ensure it is free from dirt or debris to maintain its weatherproof properties.
- Storage: Store the case in a cool, dry place away from direct sunlight and extreme temperatures when not in use.

6. Troubleshooting
- Cards not fitting: Ensure you are using Micro SD cards (including Micro SDHC/Micro SDXC/TF). The case is specifically designed for these card types and may not accommodate other formats.
- Case not closing securely: Check for any obstructions around the edges of the case or on the silicone O-ring seal. Ensure all cards are fully seated in their slots and not protruding.
- Difficulty removing cards: Micro SD cards are designed to fit snugly. Apply gentle pressure to one edge of the card to tilt it, then carefully pull it out. Avoid excessive force.
