REVERSE INDEX
The optional Reverse Index feature allows
you to type subscripts and superscripts used
in chemical formulas, footnotes, etc., without
stopping to manually move the platen up or
down.
With the Reverse Index option, the Line
Return Without Index (Arrow Key) is re-
placed by the Reverse Index Key with the
arrow pointing down. This feature will func-
tion only on a machine with a 54-tooth
ratchet on the platen. The Line Return
function is not available with Reverse
Index.
Tapes which have been recorded using the
Line Return Without Index Key will not read
correctly on a machine which has the Reverse
Index option. Every Line Return Without
Index recorded on the tape will read as a
Reverse Index.
The vertical spacing on the system is also
changed to allow two choices. The CPT may
be purchased with one of two vertical spac-
ing options: half, single, and one and one-
half spacing; or single, one and one-half, or
double spacing.
NOTE: If you make an error using the
Reverse Index feature, Line Correct and re-
type the record.
The following steps for using the Reverse Index will be based on setting the typewriter for single
spacing.

(1) Turn on and record up to the first subscript.
(2) Depress the Index Key. This will drop you one full line below the line of typing.
