How to reset CJ1M CPU12 UM protection

[bigR 0]

Anyone here can help me how to reset UM protection when I perform program uploading form CJ1M-CPU12? Somebody put a password in the PLC and that guy is already not working in our plant. No turn-over takes place especially password. I have project to adjust only a timer for the shutter door of our conveyor system. Because there is a password that tasks not possible anymore. We have no back-up program softcopy and hardcopy. So it is hard for us to decide to reprogram the machine. Is there any elite guy here can reset password embed in our PLC? Thank you very much...
