Hi...I recently purchased a Garrett MS-3 wireless system for my AT Pro detector. Recently I've found the transmitter unit blinking for no reason because it was shut off. I have no idea how it turned itself on and it happened twice, each time I then had to charge the unit back up to full because the low battery warning was blinking. Additionally, when charging it, the red light came on but the other light started blinking like it was trying to pair itself with the headphones. I called Garrett and explained the problem but they weren't able to tell me what they thought was wrong. I told them if it happens again I'd call back. Has anyone here had this problem?
