Hi all

I have this issue
I have done a hard reset on both units

The Raychart puts the chart on the radar screen ok but after about 30
seconds, the chart plotting seems to lock up. With the exception of ,
you can still move the cross-hairs and only the cross hairs. no other
button on the 601 does anything except the power button

If you power off and then back on the 601, it will work fine for abut
30 more seconds.

ANy thoughts?

Thanks
Mark

The Raychart 600 series usually had a nicad battery on a small daughter PCB.
These batteries go bad and leak, eventually getting onto the main circuit
board. I would remove the case and inspect for battery damage...carefully
clean it up and inspect for circuit traces etched open by the battery goop.
If you are lucky, a cleaning and replacement of the entire daughter assembly
with fresh battery will fix it. The assemblies run around $ 20 from
Raymarine. They are solder in assemblies, so if not qualified, get it to a
service shop. Wash hands thoroughly after you are done as this stuff contain
cadmium, a poison.
