Note related to transportation and
movement
Before transporting or moving this unit, carry out
the following operations.
Condensation (of dew) may occur inside the unit when
there is a great difference in temperature between this
unit and the outside.
This unit may not function properly if condensation oc-
curs. In this case, leave the unit for a few hours and
restart the operation after the condensation has dried
up.
Be specially cautious against condensation in a follow-
ing circumstances:
When this unit is carried from one place to another
across a large difference in temperature, when the hu-
midity in the room where this unit is installed increases,
etc.
Caution on condensation Memory bac up function
Stored contents which are cleared immediately
when power plug is unplugged from power outlet :
Clock display
N.B. function
Stored contents which will bac -up after power
plug is unplugged from power outlet:
State of power (on or standby), A, P, S, Last input
selection, AUX level, Volume control value, Balance
control, Receiving band, Frequency, Preset station,
Program Timer, TONE
Operation to reset
The microcomputer may fall into malfunction (impossibil-
ity to operate, erroneous display, etc.) when the power
cord is unplugged while unit is ON or due to an external
factor. In this case, execute the following procedure to
reset the microcomputer and return it to normal condi-
tion.
Unplug the power cord from the power outlet, then while
holding the set key on the main unit depressed, plug the power
cord again.
÷Please note that resetting the microcomputer clears
the contents stored in and it returns to condition
when it left the factory.

DISASSEMBLY FOR REPAIR / ADJUSTMENT
How to open the tray if it does not come out.
1. Turn the gear in the direction of the arrow using a bamboo stick and so on in the drawing through the hole on the loading chassis
bottom.
Note : Do not use a screw driver like a metallic instead of a bamboo stick.
(There is a danger of damaging the gear.)
2. Pull out the tray frontward by hand when it comes just out.

CIRCUIT DESCRIPTION
4-2 Precaution on handling of Optical pic -up
(KMS-260B)
The laser diode in an optical pick-up is easy to be sub-
ject to electrostatic destruction. Therefore, solder-bridge
the laser tap on the flexible board when handling the
optical pick-up.

V: 0.5V/div H: 10ms/div
INPUT: DC mode
When removing the flexible board from the connector,
make a solder bridge in advance, then remove the board.
Be careful not to remove the solder bridge before insert-
ing the connector. Moreover, take careful measures
against electrostatic destruction. The flexible board is cut
easily. Handle the flexible board with care.
4-3 Precaution during adjustment
1) Perform the adjustment and confirmation marked with “O”
in the order shown in the table when the parts below are
replaced.
2) In the test mode, perform the adjustment. After adjust-
ment is completed, cancel the test mode.
3) Perform the adjustment in the order described.
4) Use the following tools and measurement equipment.
• CD test disc TGYS-1
• Laser power meter
• Oscilloscope (with bandwidth of more than 40 MΩ)
(Calibrate the probe before measurement.)
• Digital voltmeter
• Thermometer
5) Take care that VC and GND (ground) are not connected
on the oscilloscope when two or more signals are moni-
tored on the oscilloscope. (VC and GND are short-circuit-
ed in this case.)
4-4 Creating the recordable continuous recording
disc
This disc is used for focus bias adjustment and error rate
confirmation. How to create the recordable continuous
recording disc is 3-7.

ment)

Specification : A = B
Notes :
1. Data is erased during MO write when a recorded disc is
used for this adjustment.
2. If the traverse waveform is difficult to be monitored, con-
nect an oscilloscope as shown in the figure below.
* Notes :
1. The relation between the C1 error and focus bias value
is shown in the figure below. Points “a” and “b” in the
figure are detected by the above adjustment. Focal
position “C” is automatically obtained from points “a”
and “b” by calculation.
2. The C1 error rate fluctuates. Therefore, perform the
adjustment according to the observed mean value.
