DIAGNOSTIC
TEST
<
BEFORE
ACTIVATING
THE
TEST
MODE
>
The A4
GTR
and BASS
have
a
test
mode
for
checking
the
unit’s
functions.
When this
test
mode
is
activated,
the
data
in
the
A4 is
not
initialized.
Nevertheless,
the
data
could
be
initialized
by
mistake,
so it
is
advisable
to
save any
user
data to a
MIDI
data
filer.
If
necessary,
the
data in
the A4
can
be returned
to
the
factory
settings
(preload
data) by
carrying
out the
operation
for
setting
preload
data after
this test
mode
is
activated.
The
required
equipment
and
settings
for
the
test
mode
are
pictured
below.
