Selecting New Values
When you
come
to
the
line you want to
adjust, press the
LEAP
keys
to
select new values for
the boldfaced
item in
the
right-hand column.
[LEAP->]
moves
you
forward
through
the
options;
[<-LEAP] moves
you backward. Hold-
ing down
the
LEAP
key
causes autorepeat.
If
you over-
shoot,
let
go, then press the opposite LEAP key to
go the
other direction.
Getting Out of SETUP
When you
release [USE
FRONT]
your text
returns
to
the
screen
with
the cursor
position
unchanged.
All
documents
containing highlighted
characters
will
now
reflect
the
new
setup information. Thus
you
can
highlight
and
adjust
several documents at once.
Certain
screens
affect all
documents, regardless
of
what
you have highlighted: Machine
Setup,
Main
Printer Setup,
Alternate Printer, Internal Modem
Setup, and Initial
Document
Setup.
Storage of Setup
Information
The Cat
records
new
[SETUP]
information in
its battery-
powered memory
as soon as
you
release [USE FRONT].
Also,
the
contents
of
the
battery-powered memory
are
recorded on disk
each
time you
use [D|SK].
The
[SETUP]
options you
select
for particular
documents
are
recorded
on disk and
will
be the same the next
time you play
back
the
disk. Overall information
about machine and docu-
ment
setup, such
as
whether you prefer
a
black-on-white
or
white-on-black
screen,
are
maintained
in the Cat's
battery-
powered memory. They
stay the
same
even when you turn
the Cat
off
for moving or
storage.
If
you wish, you
can use
[SETUP]
to override
the
battery-
powered memory and transfer
setup or personal
spelling
dictionary information from
the
disk
to
the
Cat.
This
adjustment
is made
in the sixth line
of
the
Machine
Setup
screen.
Set
Load
setup
from
disk
to Yes.
The battery-powered memory tallies
checksums
in
order
to determine whether or
not the
memory
content is up-to-
date.
Checksums
are
values the Cat
uses
to
see
whether
information
has been changed or
damaged.
Though
it
is
a rare
occurrence,
a
dead
battery could
cause
loss of
memory. (A
sign that
looks like
a
battery appears on the
ruler when
the battery is dead.) Playback
does
not affect
the
battery-powered memory
unless the checksums indi-
cate
that the memory
has
been damaged. In this
case,
the
information
recorded on
disk
is transferred into
the bat-
tery-powered
memory.
If
the
battery-powered memory
appears
to
have been damaged
and
no disk is in
the
drive,
the
initial
[SETUP]
information is
used.
