Replacement RayChart 620 needed

[jeronay]

My RayChart 620 screen has become unreadable. Looking for a replacement of the screen or the entire control panel. Perhaps the 630 would work in place of the 620. Any suggestions or opportunities are welcome.

Also need the tool to remove the 620 screen. The screw head is hex with a center post requiring a specialized "screw driver".

Thanks for taking the time to read and perhaps respond: jeronay@ronayenterprises.com

Still looking for the tool to take the old 620 off and replace it with a "new" 620.
