Hi
Does anybody know how to get the time/div clear plastic ring, the one under the knob for the main timebase, off its shaft?
I don't want to damage the scope but after removing the delayed sweep knob, the plastic ring with the time/div numbers is still attached to the shaft and doesn't seem to slip off.
Has anyone ever removed one of these before? I presume its the same as the 475 and 485's also.
TIA
