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.

EEPROM WRITING PROCEDURE

MD-C2

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 21.

"EJECT"

(4) Press the X-BASS 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 correction

+ 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.

2. Method for making settings other than the reference
temperature

(1) Install the MD main PWB in the mechanism, and connect it to

the main unit.

(2) Enter the test mode as shown on page 21, and insert a disc.

"AUTO YOBI"

(3) Press the PLAY MODE button.

"EEPROM SET"
(4) Selection mode using the MD1 PLAY key.
(5) Selected using the SURROUND key.
(6) Determined by the MD1 PLAY key.
(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.
(9) Enter the test mode again, perform an "AUTO YOBI", and write

its results into the EEPROM.
