BEFORE REPLACING PARTS, READ THE FOLLOWING:
5.1. REPLACEMENT NOTES
5.1.1. General Notes
1. Use only original replacement parts:
To maintain original function and reliability of repaired units,
use only original replacement parts which are listed with
their part numbers in the parts list.
2.
IMPORTANT SAFETY NOTICE
Components identified by the sign
have special
characteristics important for safety. When replacing any of
these components, use only the specified parts.
3. Parts different in shape or size may be used. However, only
interchangeable
parts
will
be
supplied
as
service
replacement parts.
4. Parts with mark "VED" in the Remarks column are supplied
from VED. Others are supplied from MKE.
5. Parts whose Ref. Nos. are the same are interchangeable as
replacement parts. Any of these parts may be ordered and
used as a replacement part.
5.1.2. Electrical Replacement Notes
1. Unless otherwise specified;
All resistors are in
Ω
, K = 1,000
Ω
, M = 1,000 k
Ω
.
2. Abbreviation

3. SERVICE OF CHIP PARTS
When servicing chip parts, please use a soldering iron of
less than 30 W.
4. When replacing 0
Ω
resistor, a wire can be substituted for
it.
5. Parts with mark "CSP" in the Remarks column are CSP
(Chip Size Package) IC.
6. IC6007 replacement note:
When replacing this IC, be sure to write the initial data with
PC-EVR Adjustment Program.
7. IC6001 replacement note:
Two types of IC6001 (M32121FCAWG or M32121MCA124)
are used on a running change basis, however IC6001
(M32121MCA124) is supplied only as a replacement part.
When replacing IC6001, as in the following cases, it is
necessary to replace the resistor at the same time or
IC6001 may have a short life.
·
When replacing IC6001 (M32121FCAWG) with IC6001
(M32121MCA124), be sure to move resistor (Ref No.
R6051) to the R6050 loacation.
