3. While holding the reset button, set your desired 3-digit combination by turning the dials.
4. Release the reset button. Your new combination is now set.
5. Test the new combination to ensure it works correctly before securing your belongings.

Important: Remember your combination. There is no master key or override if you forget it.

• Use the numerous smaller pockets for organizing stationery, cables, chargers, and personal items.
• For easy access, store frequently used items in the front access pockets or side pockets.
