network above.
Windows does not include drivers for all VIA chipsets. If
Windows Device Manager lists any hardware made by VIA
in System Devices, download the latest drivers from the VIA
website -www.viaarena.com - or the PC Manufacturer.
Try switching from 24/32 bit (16 million colors) to 16-bit
(65,000 colors) or vice versa.
To reset to defaults, run Raycleanup utility, by holding down
ctrl as RNS opens. Tick in turn:
'Clean toolbars and menus' - this resets the layout and
display to defaults.
'Remove .ini files' - this removes instruments and
configuration: have your license key to hand so you can re-
enter it
'Remove chart .cdb' - this removes the chart database, in
case a faulty chart is causing the problem.
Remove Marks .at' - this removes all of your waypoints and
routes - make sure you back them up beforehand. You can
do this by copying the file to another location.
Delete the file name 'Bounds .cch'.
Click clean up and try RNS between each of the above.
Contact Raymarine Technical Support for further help.
Has RayTech RNS been installed over the top of an earlier
version of RNS software?
Remove any RayTech programs using the Add/Remove
Programs utility and remove the file called
'c:\windows\Raytech .ini'.
Re-install RayTech RNS.
