THE DIFFERENCE BETWEEN
DS-IA
AND
DS-1
Because of IC modifications, the part name
will
be changed from DS-1
(ACAADAPTORTYPE) to DS-IA (PSA
ADAPTORTYPE),
beginning
from
SNo.JG83100
of
1031
Lot
(production in November,
1994)
Although
the part
name
is changed,
the marking
“DS-1”
will
remain
indicated on the pedal of the products. Therefore, the
following
notes
should be referred to for
distinguishing the DS-IA from the DS-1.
The DS-IA will have eight modified parts or items:
the
veneered
box,
owner's
manual, case, PCB (including components mounted on the PCB),
insulation spacer, bottom cover, bottom caution and adaptor caution.
•
To
distinguish
between
the
DS-1 and
DS-IA
1. Individual box : Check the printed pattern on the upper surface of the
individual
box.
