How to change the password of the mechanical password safe?

The first step: first open the safe door, and then turn the switch dial counterclockwise to turn the lock mark to the switch indication line position.
Step 2: Rotate the password dial counterclockwise, and the alignment stops when the password tick mark "*" turns to the replacement password indication tick mark for the fourth time (or more than 4 times). (If you turn, please do n’t return it, you can turn it again and stop the alignment)
Step 3: Turn the code dial clockwise, and the alignment stops when the code is scaled. (If it exceeds, please do not return it, you need to start again from the second step, otherwise it will lead to wrong password replacement)
Step 4: Rotate the password dial counterclockwise, and stop exactly when the password tick “*” is turned for the second time to change the password indicator tick. (If it exceeds, please do not return it, you need to start again from the second step, otherwise it will result in the wrong code for password replacement.
Step 5: First insert the replacement password key into the replacement password key hole behind the door; then rotate the replacement password key 90 degrees clockwise; during the password replacement process, please use the replacement password key to maintain this state.
Step 6: For example, the new replacement password is 96, 11, 23, turn the password dial counterclockwise, and the alignment will stop when the new password scale "96" turns to the replacement password indication scale line for the fourth time (or more than 4 times). (If you turn, please do n’t return it, you can turn it again and stop the alignment)
Step 7: Turn the password dial clockwise, and the alignment will stop when the new password scale "11" turns to the replacement password indication scale line for the third time. (If you turn, please do not return, you need to start again from the sixth step, otherwise the new password will lead to wrong)
Step 8: Turn the password dial counterclockwise, and the alignment will stop when the new password scale "23" turns to the replacement password indication scale line for the second time. (If it is passed, please do not return it, you need to start again from the sixth step, otherwise it will lead to wrong password replacement)
Step 9: Rotate the replacement password key 90 degrees counterclockwise; replace the replacement key to restore the original position; pull out the replacement replacement key.
