Urgent. How to use the combination lock of the suitcase?

The current situation is that the initial password has been destroyed or forgotten. The steps to retrieve a password and set a new password are as follows:

First, the side of the combination lock is facing the sunlight or strong light, so that the inside of the lock gear of the combination lock can be clearly seen.

Second, each gear has a groove, and the grooves of the three gears turn in the same direction.

Third, after the three grooves are aligned, write down the three numbers exposed outside the combination lock.

4. Then, press and hold the on key, toggle the three gears, and add "1" to the numbers on the three gears in turn until the ON key can be turned on. When the on key can be turned on, the displayed number is the current correct "password".

Fifth, then set a new password. First, press and hold the switch, and then turn it to the desired number.

6. Release the switch at this time, and the current set of numbers will be successfully modified into a new password.
