Cautions
Beware of condensation
When water vapor comes into contact with the surface of
cold material, water drops are produced. If condensation
occurs, correct operation may not be possible, or the unit
may not function correctly.
This is not a malfunction, however, and the unit should be
dried.
(To do this, turn the POWER switch ON and leave the unit
as it is for several hours.)
If a problem occurs
If this product is subjected to strong external interference
(mechanical shock, excessive static electricity, abnormal
supply voltage due to lightning, etc.) or if it is operated
incorrectly, it may malfunction or the display may not
function correctly. If such a problem occurs, do the
following:
• Unplug the AC power lead from the AC socket.
• Wait about 20 - 30 seconds and then plug the AC power
lead back into the AC socket.
• Press the reset key on the back of the unit.

Be especially careful in the following conditions:
• When the unit is brought from a cold place to a warm place
and there is a large temperature difference.
• When a heater starts operating.
• When the unit is brought from an air-conditioned place to
a place of high temperature with high humidity.
• When there is a large difference between the internal
temperature of the unit and the ambient temperature, or in
conditions where condensation occurs easily.

TROUBLE SHOOTING
When MD fails operate
If the objective lens of optical pickup is contaminated, MD may fail to operate. At first, clean the objective lens to check playback
operation. If MD fails persistently to operate, perform checks as follows.
If dust or foreign substance is accumulated on the pickup lens, playback is disturbed and indication of TOC (content of tracks) may
be disabled. Before adjusting check that the lens is clean. If the lens is contaminated, treat it as follows.
Turn off power supply, impregnate the lens cleaning paper with a small quantity of isopropyl alcohol, and gently wipe the lens with
it with due care so that the lens is not damaged. At this time do not touch the lens directly with your finger.

Measuring Method
After the automatic adjustment is performed in the AUTO
mode (test mode) with the aid of high refection MD disc
("COMPLATE" is displayed), the Lissajous's waveform (x-y) is
adjusted.
1. Slightly loosen the 3 screws of spindle moto, and maken an
adjustment, observing the Lissajous's waveform.
2. After adjustment tighten the screw in arder of 1 , 2 , 3 .

The DC voltage is an actual reading measured
with a high impedance type voltmeter. The
measurement value may vary depending on
the measuring instruments used or on the
product. Refer to the voltage during RECORDABLE MD PLAY unless otherwise specified;
The value shown in ( ) is the voltage measured at the moment of STOP. The voltage
followed by (REC) refers to the value during
MD RECORDING.

Notes
1. KENWOOD follows a policy of continuous advancements in development. For this reason specifications may be changed without notice.
2. The full performance may not be exhibited in an extremely cold location (under a water-freezing temperature).
Note:
Component and circuit are subject to modification to insure best operation
under differing local conditions. This manual is based on Europe (E) standard,
and provides information on regional circuit modification through use of alternate schematic diagrams, and information on regional component variations
through use of parts list.
