TEST MODE

Note: Use following buttons in the test mode.

no mark: Button of amplifier unit (TA-S3)
*1 : Button of tuner unit (ST-S3)
*2 : Button of CD unit (CDP-S3)

[MC Test Mode]

Enter the MC Test Mode

1. Press the I/1 button to turn the power on.

2. While pressing the both [STEREO/MONO] *1 and [2CH/

MULTI C] buttons, press the [MUSIC MODE A] button.

3. “GROOVE” indication blinks on the fluorescent indicator tube
in the midst of MC test mode.

4. This mode has two modes (mode 1/mode 2).

5. To change the modes, press three buttons in the same manner
as entering this mode (step 2). Each time the step 2 operation
is repeated, it changes modes alternately.

6. To distinguish the mode, turn the [VOLUME] knob clockwise
or counterclockwise. Then display is shown as follows.

Mode 1: only “MIN” or “MAX”
Mode 2: “MIN”, “1 to 30” or “MAX”

Releasing the MC Test Mode

T o release from this mode, press the I/1 button or disconnect the
power cord.

[GC Test Mode]

Enter the GC Test Mode

Procedure 1:

1. Press the I/1 button to turn the power on.

2. While pressing the both [STEREO/MONO] *1 and [2CH/

MULTI C] buttons, press the [CLOCK/TIMER] *

3. LEDs and fluorescent indicator tube are all turned on of all
units.

Procedure 2:

1. Press the I/1 button to turn the power on.

2. While pressing the both [PLAY MODE] *2 and x *2 buttons,
press the Z (DISC 1) *2 button.

3. LEDs and fluorescent indicator tube are all turned on of all
units.

Version Display Mode

Procedure:

1. Enter the GC test mode.

2. Each time the [TUNER MEMORY] *1 or [DISC 1] *2 button is
pressed, microcomputer or mechanism deck version is dis­played of each unit.

3. Press the [TUNING +] *1 or [DISC 3] *2 button to detail is
displayed the version.

Key Check Mode

Procedure:

1. Enter the GC test mode.

2. Press the [TUNING --] *1 or [DISC 2] *2 button to set the key
check mode.

3. In the key check mode, the fluorescent indicator tube displays
“K 0 J 0 V 0”. Each time a button is pressed, “K” value in­creases. However , once a button is pressed, it is no longer tak en
into account.
“J” value increases like 1, 2, 3 ... if turn the
knob clockwise, or it decreases like 0, 9, 8 ... if turn the JOG
dial counterclockwise.
“V” value increases like 1, 2, 3 ... if turn the [VOLUME] knob
clockwise, or it decreases like 0, 9, 8 ... if turn the JOG dial
counterclockwise.
