/
This switch selects the operating mode for the
memory system. The M position is a momentary
switch position, which stores
characters posted on the TV screen up to the point
where the lever is depressed. The reader will
continue to 1ist characters after the lever is pressed,
though. The MR position is used to recall up to a
page of copy. In the MR position, only the
memorized copy will be displayed (not any sub­
sequent characters), but the YR-90 I will hold in
another register all copy that would be displayed,
had the MR position not been selected. Upon
return to the OFF position, the TV screen returns
to normal monitoring.

relationship, to permit proper operation.
