2. Setup and Initial Use
2.1 Setting the TSA Combination Lock
Your Coolife luggage is equipped with a mounted TSA combination lock for enhanced security. The lock is preset to 0-0-0.
- Ensure the dials are set to the factory default combination (0-0-0).
- Locate the reset button (a small, recessed button, often requiring a pen or pointed object to press).
- Press and hold the reset button until you hear a click.
- While holding the reset button, set your desired 3-digit combination by turning the dials.
- Release the reset button. You should hear another click, confirming your new combination is set.
- Test your new combination by scrambling the dials and then entering your set code to open the lock.
Important: Remember your combination. There is no master key provided for users. TSA agents have a universal key to open the lock without damaging your luggage.
