How
to
change a variable
The variables
are
stored
in
the
PM
(Personality Module) which is either a nonvolatile RAM
or
an
EEPROM.
When
new
data is entered, the data is
NOT
STORED
UNTIL
THE
< S > KEY
IS
PRESSED. Thus you can
adjust the
tuning
until satisfied and then save
the
variables.
If
not
satisfied with
the
new
values, then
the
previous values can be restored
by
resetting
the
drive as long as the
<S>
key was
not
pressed. A write
protect
jumper
is
available
to
prevent
the
variables
from
being altered.
Make
sure
the
write
protect
jumper
is
in
the
non-write-protect
position
before
powering
up
the
drive
if
it
is
going
to
be
tuned
(refer
to
Figure 5-2.).
Under

no
circamstance,
· shoa1d·
1he
write-protect
jumper
be
moved
while
power
is
applied.
The
result
could
be
a
damaged
personality
module.
To
change
the
value
of
a variable, move
the
cursor, using
the
<U
>
or
<Enter>
keys
to
the
location
immediately
to
the
left
of
the
variable
to
be
changed
and
then enter
the
new value.
As
the
data is being
entered,
the
present data
for
that variable will
be
erased off
the
screen and
the
new
data will
be
displayed
as
it
is
being entered. Press
<Enter>
to
complete
the
data entry. While entering data
for
a variable, if
you
wish
to
restore the previous value, press
the
<ESC>
key
to
ignore
the
present value and restore
the
previous value.
