IMPORTANT SERVICE NOTES (For U.S.A.Only)

BEFORE RETURNING THE AUDIO PRODUCT

(Fire & Shock Hazard)
Before returning the audio product to the user, perform the
following safety checks.

1. Inspect all lead dress to make certain that leads are not
pinched or that hardware is not lodged between the chassis
and other metal parts in the audio product.

2. Inspect all protective devices such as insulating materials,
cabinet, terminal board, adjustment and compartment
covers or shields, mechanical insulators etc.

3. To be sure that no shock hazard exists, check for leakage
current in the following manner.

* Plug the AC line cord directly into a 120 volt AC outlet.
* Using two clip leads, connect a 1.5k ohm, 10 watt resistor

paralleled by a 0.15µF capacitor in series with all exposed
metal cabinet parts and a known earth ground, such as
conduit or electrical ground connected to earth ground.

* Use a VTVM or VOM with 1000 ohm per volt, or higher,

sensitivity to measure the AC voltage drop across the
resistor (See diagram).

* Connect the resistor connection to all exposed metal parts

having a return path to the chassis (antenna, metal cabinet,
screw heads, knobs and control shafts, escutcheon, etc.)
and measure the AC voltage drop across the resistor.

1,2

2

NO

YES

Correct

Compact discs are fairly resistant to damage, how-

ever mistracking can occur due to an accumulation

of dirt on the disc surface.

Follow the guidelines below for maximum enjoy-

ment from your CD collection and player.

Do not write on either side of the disc, particu-

larly the non-label side.

Signals are read from the non-label side. Do not

mark this surface.

Keep your discs away from direct sunlight, heat,

and excessive moisture.

Always hold the CDs by the edges. Fingerprints,

dirt, or water on the CDs can cause noise or

mistracking. If a CD is dirty or does not play prop-

erly, clean it with a soft, dry cloth, wiping straight

out from the center, along the radius.

CD SECTION

• Adjustment

Since this CD system incorporates the following automatic
adjustment functions, readjustment is not needed when
replacing the pickup. Therefore, different PWBs and pickups
can be combined freely.
Each time a disc is changed, these adjustments are
performed automatically. Therefore, playback of each disc
can be performed under optimum conditions.

Items adjusted automatically

(1) Offset adjustment (The offset voltage between the head

amplifieroutput and the VREF reference voltage is
compensated inside the IC.)
* Focus offset adjustment
* Tracking offset adjustment

(2) Tracking balance adjustment (waveform drawing 17-4

EEPROM WRITING PROCEDURE

MD-M3/M1

EEPROM (IC1402) writing procedure

1. Method for setting the reference temperature value

(This setting should be performed quickly at a room
temperature, between 21 C and 29 C when the PWB is not
hot.)

(1) When replacing the EEPROM, wait until it has cooled down.
(2) Connect the main unit using the single MD main PWB.
(3) Enter the test mode as shown on page 20.

"EJECT"

(4) Press the NORMAL button.

"TEMP "

:Measured temperature, : Temperature setting

(5) Find the temperature correction value for the current ambient

temperature on the following table. Adjust the temperature
correction value using the jog dial.

Ambient temperature

+ 21.0 °C ~ + 23.2 °C -1 H
+ 23.3 °C < + 26.8 °C ± 0 H
+ 26.9 °C < + 29.0 °C +1 H

An example: When ambient temperature is 22°C and measured

temperature is 7AH
Temperature setting = 7A H - 01 H

= 79 H
* When the measured temperature fluctuates between
two values, take lower one (if temperature fluctuates
between 7AH and 79H, take 79H).

(6) Press the POWER button and write the temperature setting into

the EEPROM.

correction

2. Method for making settings other than the reference
temperature

"AUTO YOBI"

(3) Press the PLAY MODE button six times.

"EEPROM SET"
(4) Selection mode using the PLAY/PAUSE button.
(5) Selected using the PRESET EQUALIZER button.
(6) Determined by the PLAY/PAUSE button.
(7) Using the jog dial, adjust the settings as shown in the "List of the

EEPROM contents".
(8) Press the POWER button, and the settings will be written into

the EEPROM.
