I was wondering if you could help me. After reading your post a while back about getting a wireless security system for you safe i did the same. I purchased the same wireless system from china on ebay. Well, the install instruction appear to have been poorly translated. I can't seem to figure out how to set my pass code on the thing. I've found in the instructions where it tells you have to turn settings on and off but it all requires a pass code. Did your instructions tell you how to set up your pass code? I've contacted the seller but he really isn't any help. Any help would greatly be appreciated.
