MODES OF
OPERATION
Normal
Mode
When
both shift
keys are off,
the main keys
act according to
the label on
each key
face.
This
is called "normal"
mode,
and in this mode
the keys are
referred
to as
"action
keys".
Parameter
Set-up
Mode
When
the
"SET UP" shift
key is "on",
the main keys
act according
to the label
above
each key. This is
"parameter
set-up" mode.
Number
Entry Mode
When
the "NUMBER
RETURN"
shift key
is "on", the main
keys act
as a number
keypad,
according to
the label below
each key. This
is "number
entry" mode.
2.3
POWER UP
At power
up, one
of
three
messages
is displayed:
"Power Restored"
This means that,
after an
interruption
in the mains supply
(whether deliberate
or
accidental),
the SI 1.287
remembers
all the existing
menu settings,
history
file, and
stored menu set-ups,
using its
internal
battery.
"Reset"
This
means
that
the
SI 1287 has
returned all the
menu settings
to the default
state,
but left the history
file and
stored
set-ups as they were.
This
happens if
the SI1287
detects a fault
in its data base (existing
menu
settings).
It may
occur, for example,
if the
SI 1287 has been without
power for
more
than
the 1
00 hours, which
the internal
battery
is guaranteed to maintain
the
memory
(but not long
enough to
corrupt the
history file and stored
menu set-ups).
"Initialised"
This
means that all
menu settings
have been returned
to the default
state, and
the
history
file and
stored menu
set-ups have
been erased. This
appears at
power up
when the
SI1287
has been switched
off for more
than 100 hours.
