Caution on condensation

Condensation (of dew) may occur inside

the unit when there is a great difference in

temperature between this unit and the out-

side.

This unit may not function properly if con-

densation occurs. In this case, leave the

unit for a few hours and restart the opera-

tion after the condensation has dried up.

Be specially cautious against condensation

in a following circumsatance:

When this unit is carried from a place to

another across a large difference in tem-

perature, when the humidity in the room

where this unit is installed increases, etc.

Note related to transportation

and movement

Before transporting or moving this unit,

carry out the following operations.

(1) Remove the CD or MD from the unit.

(2) Press the 6key of the MD.

(3) Wait for some time and verify that the

display becomes as shown in the figure.

(4) Press the 6key of the CD.

(5) Wait for some time and verify that the

display becomes as shown in the figure.

(6) Wait a few seconds and turn the unit

OFF.

2. An erasure prevention control is not detected in the test

mode. Be careful not to enter the continuous recording

mode using a disc containing the data that should not be

erased.

3. Do not record continuously for more than five minutes.

4. Take care that no vibration is applied during continuous

recording.

5. ELECTRICAL ADJUSTMENT

5-1 Precaution during confirmation of Laser

Diode emission

During adjustment, do not view the emission of a laser

diode from just above for confirmation. This may dam-

age your eyes.

5-2 Precaution on handling of Optical pick-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 han-

dling the optical pick-up.

4-5 Continuous Playback Mode

4-6 Continuous Recording 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

inserting the connector. Moreover, take careful mea-

sures against electrostatic destruction. The flexible

board is cut easily. Handle the flexible board with care.

5-3 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.)

5-4 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 4-6.

* 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.

CAUTION: For continued safety, replace safety critical components only with manufacturer's recommended parts (refer to

parts list). indicates safety critical components. For continued protection against risk of fire, replace only with same type and

rating fuse(s). To reduce the risk of electric shock, leakage-current or resistance measurements shall be carried out (exposed

parts are acceptably insulated from the supply circuit) before the appliance is returned to the customer.

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.

The DC voltage is an actual reading measured with a high impedance type volt-

meter as the AM/FM signal generator is specified to the conditions as shown in the

list below. The measurement value may vary depending on the measuring instru-

ments used or on the product. The value shown in ( ) is actual reading measured in

the AM mode.

CAUTION: For continued safety, replace

safety critical components only with manu-

facturer's recommended parts (refer to

parts list). indicates safety critical com-

ponents. For continued protection against

risk of fire, replace only with same type

and rating fuse(s). To reduce the risk of

electric shock, leakage-current or resis-

tance measurements shall be carried out

(exposed parts are acceptably insulated

from the supply circuit) before the appli-

ance is returned to the customer.
