THE DIFFERENCE BETWEEN
DS-IA
AND
DS-1
Because of IC modifications, the part
name
will
be changed from DS-1
(ACA ADAPTORTYPE)
to
DS-IA (PSA
ADAPTOR
TYPE),
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.
