NIR,
I am going to unplug the sensors, and the motors, each one at a time, on an old camera. Maybe I will hear "beeps" that will help us identify which two are causing the pattern you hear. Please give me about 30 minutes to experiment and write something back.
Maybe someone else has (or can find) the real beep code list for the CG03+ and can post it? That would be more reliable.
