The commissioning and setting of the vault door lock

There is a factory default secret (50) opening method:

Rotate the cipher dial counterclockwise so that the number (50) is "turned on" four times and aligned exactly with the "opening mark" on the fifth time. Then rotate the cymbal dial clockwise until it stops and the lock is opened.

Pre-set password (such as 10 20 30 40) opening method:

1.Turn the dial clockwise so that after the “on” mark has passed through the “password” four times, continue to rotate the dial slowly in a clockwise direction and make the first passcode on the fifth time (10) Align exactly with the "open" mark.

2. Then turn the dial counterclockwise to make the second password (20) go through the “opening mark” three times, then continue to rotate the dial slowly in a counterclockwise direction, and make the second password (20) in the fourth time. Align exactly with the "open" mark.

3. Then slowly turn the dial clockwise to make the third password (30) go through the “open flag” twice, then continue to slowly rotate the dial clockwise, and make the third password for the third time. (30) Exactly aligned with the "opening mark".

4. Then turn the dial counterclockwise so that the fourth code (40) passes through the “open flag” once, and then continue to slowly rotate the dial counterclockwise, and the second code (40) is used for the second time. Align exactly with the "open" mark.

5. Turn the lock dial clockwise until it stops and the lock is opened.

Note: When turning on the code lock, you should slowly turn the dial. If the required password exceeds the opening mark, you must not turn to set it up. You must open the code lock again in the opening sequence.
