[C320-list] Raymarine ST 4000 autopilot

[Darrell]

I realize that there was prior discussion about problems with this unit. 
However , mine has worked fine since I purchased it in 2005. That said, it 
has started displaying a low voltage warning and beeping after about an hour 
of motoring. If I just push Auto it disapears and then reappears an hour or 
so later. I have checked my batteries and the gage on the pannel each time 
and they look fine. I haven't tested power to the autopilot control head. 
Has anyone experienced this. or know if this unit has been recalled for 
replacement with a newer model,
