NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electro-
static break-down because of the potential difference generated
by the charged electrostatic load, etc. on clothing and the human
body.
During repair, pay attention to electrostatic break-down and also
use the procedure in the printed matter which is included in the
repair parts.
The flexible board is easily damaged and should be handled with
care.
NOTES ON LASER DIODE EMISSION CHECK
Never look into the laser diode emission from right avove when
checking it for adustment. It is feared that you will lose your sight.
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK
(KMS-242E).
The laser diode in the optical pick-up block may suffer electro-
static break-down easily. When handling it, perform soldering
bridge to the laser-tap on the flexible board. Also perform mea-
sures against electrostatic break-down sufficiently before the op-
eration. The flexible board is easily damaged and should be handled
with care.

NOTE FOR REPLACING THE IC600
There are two types of IC600 on the MAIN board. In case IC600
is replaced, after surely checking which type of IC600 is mounted
on the set, it exchanges according to the following procedure.
In case of type1:
After surely checking the type of IC600 newly mounted on the
MAIN board, it replaces in the procedure according to each type.
Replacing procedur to type1
1. IC600 is replaced for MN101E01KDJ (PART No. 6-804-093-
01).
Replacing procedur to type2
1. IC600 is replaced for MN101E01JRD1 (PART No. 6-804-511-
02).
2. C606 is replaced for ceramic chip 15PF (PART No. 1-162-
917-11).
3. C607 is replaced for ceramic chip 12PF (PART No. 1-162-
916-11).
In case of type2:
Replacing procedure
1. IC600 is replaced for MN101E01JRD1 (PART No. 6-804-511-
02).
