[1] 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.

3. 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 – 1

XL-HP515

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

4. CD ERROR CODE DESCRIPTION

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 process.
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 "U******".

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

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

3.Press OPEN/CLOSE button until "WAIT"--> "FINISHED" appears.

CHAPTER 3. MECHANICAL DESCRIPTION

[1] REMOVING AND REINSTALLING THE MAIN PARTS

1. TAPE MECHANISM SECTION

Perform steps 1 to 9 of the disassembly method to remove the tape mechanism.(see page 3-3,3-4)

1.1. How to remove the Record/Playback Head (See Fig. 1)

1.When you remove the screws (A1) x 2 pcs and (A2) x 1 pc., the record/playback head can be removed.

1.2. How to remove the Pinch Roller (See Fig. 2)

1.Carefully bend the pinch roller pawl in the direction of the arrow <A>, and remove the pinch roller (B1) x 1 pc., in the direction of the arrow <B>.

NOTE: When installing the pinch roller, pay attention to the spring mounting position.

1.3. How to remove the Belt (See Fig. 3)

2. CD MECHANISM SECTION

Perform steps 1 to 4 and 11 to 12 of the disassembly method to remove the CD mechanism.(see page 3-3,3-4)

2.1. How to remove the Optical Pickup (See Fig. 1)

1.Remove the stop washer (A1) x 1 pc and gear (A2) x 1 pc.

2.Remove the screws (A3) x 2 pcs and shaft (A4) x 1 pc.

3.Remove the optical pickup.

NOTE: After pulling out the optical pickup connector, wrap the tip of it with conductive aluminium foil or the like to protect the optical pickup from the static electricity.

2.2. How to remove CD Disc (See Fig. 2~6)

1.When CD is at play position, rotate reduction gear C clock-wise as shown in Figure 2 Until disk tray is at ‘STOCK’ position, then rotate the gear further to eject the disk tray (Figure 6) so that CD can be removed from the tray.

2.In another case, if CD mechanism is at tray No. 1 play position and to remove CD located in tray No. 3, the procedure is as follows:

If the gear up down board is located at tray No. 1 position, then rotate Reduction gear C clock-wise until Disc tray is at stalk ‘STOCK’ position. Rotate reduction gear D clock-wise (Figure 3) to move the CD mechanism to tray No. 3 position. This is confirmed by checking the gear up down board position Base on the marking as indicated on the main chassis as shown in Figure 4.

•Usually changer is covered with top plate. As for reference purpose, we exclude the top plate for easy viewing. (Figure 5,6)

CHAPTER 6. CIRCUIT SCHEMATICS AND PARTS LAYOUT

[1] NOTES ON SCHEMATIC DIAGRAM

•Resistor:

To differentiate the units of resistors, such symbol as K and M are used: the symbol K means 1000 ohm and the symbol M means 1000 kohm and the resistor without any symbol is ohm-type resistor. Besides, the one with “Fusible” is a fuse type.

•Capacitor:

To indicate the unit of capacitor, a symbol P is used: this symbol P means pico-farad and the unit of the capacitor without such a symbol is microfarad. As to electrolytic capacitor, the expression “capacitance/withstand voltage” is used.

(CH), (TH), (RH), (UJ): Temperature compensation (ML): Mylar type

(P.P.): Polypropylene type

•Schematic diagram and Wiring Side of P.W.Board for this model are subject to change for improvement without prior notice.

•The indicated voltage in each section is the one measured by Digital Multimeter between such a section and the chassis with no signal given.

1.In the tuner section, indicates AM indicates FM stereo

2.In the main section, a tape is being played back.

3.In the deck section, a tape is being played back.

4.In the power section, a tape is being played back.

5.In the CD section, the CD is stopped.

•Parts marked with “ ” ( ) are important for maintaining the safety of the set. Be sure to replace these parts with specified ones for maintaining the safety and performance of the set.
