This question is regarding Ultra Valquest DC70 Dual Valve Thermostatic Cartridge (20 Teeth) - DC70T20-M

How do I remove the brass cartridge retaining ring?

I need to replace the cartridge in my shower but I can't loosen the retaining and don't want to damage the thread by grasping it too tightly. Please can you tell me the best way to remove it?
