C-Map problem? I'm seeing pink things.

[HoveRuss]

Can anyone help? I've bought a C-Map NT Max chart of Australia for my Standard Horizon plotter and the chart is covered in small pink triangles contained in a circle. They're in a regular grid pattern right across the chart a few hundred metres apart. They're bloody annoying and distracting and I'd like to see the back of them but can't find out what they are or how to get rid of them.

Any ideas?

Thanks

Russ

At least you aren't seeing little pink elephants. That would be really bad.

Are these triangles icons for something? Or just "interference"...?
