While a diagnostics program
is
executed,
[[0]]
to
[[9]]
of
the
typewriter
keys
function
as
data
keys
irrespective
of
[[Shift]].
For example, even if
[[1]]
is
entered
while
the
shift
key
of
the
typewriter
keys
is
pressed,
numeric
data
[1]
is
entered.
(3.2) Hexadecimal Code
Entry
Codes from [0]
to
[9] can be
entered
in
the
same
manner
as
the
decimal numbers; codes
[A],
[B],
[C],
[D],
[E],
and
[F.]
should
be
entered by using
[[A]]
to
[[F]]
of
the
typewriter
keys.
Like
the
decimal
code
entry,
while
a
diagnostics
program
is
executed,
[[A]]
to
[[F]]
of
the
typewriter
keys function
as data keys irrespective
of
the
state
of
[[Shift]].
For
example,
even if [a]
is
entered
while
the
shift
key
is
pressed, code [Al
is
entered.
