Hi new pharmacist here. I worked my full shift last night and I had problems opening up the CII safe. You would think someone who did 4 years undergrad and 4 years pharmacy school would be able to figure it out but it only came up at the end of my shift when i had to finally open it. Anyways I turned the key all the way and you could hear the timer clicking. This went on for about 10 minutes. It did stop but the safe was still locked. Do you have to reinsert the key or am I missing something? Also should the timer stop or will it keep clicking. The tech i was working with didn't really know and she said the green light is supposed to go off but stopped working months ago....go figure
