C U R S O R Switch
Displays the bright spot (cursor point) on the main
channel side according the combinations of settings of
M O D E (20) and D I S P L A Y M O D E (32) . Cursor move-
ment is in two speeds. T h a t is, when the right or left
button is pressed once, the cursor point moves to the
right or left, respectively, by one w o r d ; holding the
right or left button depressed moves the cursor con-
tinuously to the corresponding direction as far as the
button is depressed. T h e cursor point will stop upon
arrival at the right or left end. T h e cursor point is
movable between 2 and 2000 words (memory address).
The cursor point display mode is available to the
following combinations:
