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
