IMPORTANT SERVICE NOTES

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 1.5 kohm, 10 watt resistor paralleled

by a 0.15 µF 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.

All check must be repeated with the AC line cord plug connection reversed. Any reading of 0.3 volt RMS (this corresponds to 0.2 milliamp. AC.) or more is excessive and indicates a potential shock hazard which must be corrected before returning the audio product to the owner.

[4] 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 amplifier output and the VREF reference voltage is compensated inside the IC.)

* Focus offset adjustment

* Tracking offset adjustment

2) Tracking balance adjustment

3) Gain adjustment (The gain is compensated inside the IC so that the loop gain at the gain crossover frequency will be 0 dB.)

* Focus gain adjustment

* Tracking gain adjustment

Error Explanation

01 When Pickup set inner position, inner switch cannot detect

'ON' level for 10 secs. 10* CAM error. Can't detect CAM switch when CAM is moving. 11* When it detect cam operation error during initialize pro-

cess. 20* TRAY error. Can't detect TRAY switch when TRAY is mov-

ing. 21* When it detect TRAY operation error during initialize pro-

cess.

31 When it change to CD function, DSP cannot read initial

data.

* 'CHECKING'

If Error is detected, 'CHECKING' will be displayed instead of 'ERCD**'. 'ER-CD**' display will only be displayed when error had been detected for the 5th times.

Speaker abnormal detection and +B PROTECTION display

In case speaker abnormal detection or +B PROTECTION had

occurred, it can be check by pressing ‘POWER’, ‘ ’ and ‘X-BASS’ button. MicroComputer version number will displayed as “XM******”.

Press ‘GAME/VIDEO’ button during version number display and then press ‘POWER’, ‘MEMORY/SET’ and ‘GAME/VIDEO’ button. Display will show “S** B**”. S is referring to speaker abnormal detection and B is referring to +B PROTECTION. ** is in hex valve.

BEFORE TRANSPORTING THE UNIT

The following process need to be taken after set tapering/parts replacement.

1. Press the ON/STAND-BY button to enter stand-by mode.

2. While pressing down the button and the X-BASS/DEMO button, press the ON/STAND-BY button. The Micro Computer version number will be displayed as “XM******”.

3. Press OPEN/CLOSE button until “WAIT”→ “FINISHED” appears.

4. Unplug the AC cord and the unit is ready for transporting.

+B PROTECTION is condition when irregular process occur on power supply line.
