Hello, I have a PE+ that I’m am trying to setup. When I bought it the battery on the mpu was dead. Replaced battery, installed set chip 38, powered up with the door open and get the set denomination/enable bill validator screen, selected .25 cents enable bv, pressed the test switch to save options and nothing, did not save options. Replaced test switch will a new one same thing did not save options. If I close the door with the game chip installed and start it up I get call attendant error, open the door I now get call attendant, door open and cmos error. Press and hold test switch for 5 sec and nothing no beep nothing. So I am stuck can not go any further until I am able to save options. Any thoughts?
