Warnings

When the X-Y button is depressed, the X signal is derived from channel 2 instead of scanning left to right.

The manual warns:

Should both input voltages be missing or fail in the X-Y mode, a very bright light dot is displayed on the screen. This dot can burn into the phosphor at a too high brightness setting (INTENS. knob) which causes either a lasting loss of brightness, or in the extreme case, complete destruction of the phosphor at this point.
