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.

TEST MODE
The test mode applied to this microcomputer has three modes, namely ordinary test mode to be used for adjustment or
measurement, aging test mode to be used for aging test, and self-diagnosis test mode for self-inspection in case of final product
inspection.
1. Turning on the test mode
To turn on the specific test mode, press the POWER ON/STAND-BY button, holding down the following two buttons in the
ordinary stand-by mode (power off state). In this case only the main unit button is valid. Even when the POWER of remote control
button is set to on, the test mode is not turned on.
[Ordinary test mode]
1. CD Test Mode (TEST 1)…………………… BASS/TREBLE + FF/FWD
2. Tuner Test Mode (TEST 2)………………… BASS/TREBLE + REW/REV
3. Electronic volume Test Mode (TEST 3)…… BASS/TREBLE + REC
4. Timer Test Mode (TEST 4)………………… MEMORY/SET + REC
5. LCD Test Mode (TEST 5)……………………MEMORY/SET + REW/REV
[Self-diagnosis Test Mode]
1. Button input diagnosis test mode (TEST6).… MEMORY/SET + PLAY
2. CD Test Mode (TEST 1)
In the CD test mode the operation of each step is enabled even when the LID-SW is off. However, if focus cannot be set in step 3 or any
error processing is started, it is impossible to proceed to the next step. When the error processing is started, operations other than
termination of test mode by pressing the POWER ON/STAND-BY button or return to the step 1 by pressing the STOP button are inhibited.
1. Step 1 Mode
When the CD test mode is turned on, the following indication lights, the processing (until turning-off of CD STB terminal of CD
initialization operation flow) is executed, and the next button input is waited.
After lighting for one second
If the following operation buttons are pressed in this state, the operation is performed as follows.
"POWER ON/STAND-BY" ... The test mode is turned off, the power is turned off, and the ordinary stand-by mode is set.
"FF/FWD" ................. After the pickup returns once to the innermost periphery, it slides toward the outer periphery while this
button is held down.
"REW/REV" .............. After the pickup returns once to the innermost periphery, it slides toward the inner periphery while this
button is pressed. However, if PU-IN is on, input is invalid.
"PLAY" ..................... Shift to step 2
"STOP" ..................... Invalid
"REC PAUSE" .......... Shift to step 5
–8–
XL-55/55C
* In case of initialization the pickup is moved toward the inner periphery. Any buttons other than POWER ON/STAND-BY button
are not accepted until the shift of pickup to the inner periphery is completed at this time. If PU-IN SW ON cannot be detected
within 10 seconds, the slide motor is stopped, and the following error indication appears. Press the POWER ON/STAND-BY
button to end the test mode, or press the STOP button to return to step 1. Any other operations are inhibited.
2. Step 2 Mode
When the "PLAY" button is pressed in this mode, the laser lighting command LDON (8400) is sent, and the laser is turned on.
Other operations are not performed.
If the following buttons are pressed in this state, the operation is performed as follows.
"POWER ON/STAND-BY" .. The test mode is turned off, the power is turned off, and the ordinary stand-by mode is set.
"FF/FWD" ................ The pickup slides toward the outer periphery while this button is held down.
"REW/REV" ............. The pickup slides toward the inner periphery while this button is held down. However, if PU-IN is on, input
is invalid.
"PLAY" ..................... Shift to step 3
"STOP" .................... Return to step 1
"REC PAUSE" ......... Shift to step 5
3. Step 3 Mode
The laser is kept lighting. The processing (until turning-on of CLV servo of CD initialization operation flow) is executed, and
the next button input is waited. (The focus servo is turned on, and focus search is performed.)
The focus search is repeated until the focus is set.
When the following operation buttons are pressed in this state, the operation is executed as follows.
"POWER ON/STAND-BY" .. The test mode is turned off, the power is turned off, and the ordinary standby mode is set.
"FF/FWD" ................ The pickup slides toward the outer periphery while this button is held down.
"REW/REV" ............. The pickup slides toward the inner periphery while this button is held down. However, if PU-IN is on, input
is invalid.
"PLAY" ..................... If the focus has been set, shift to step 4 is executed. If the focus has not been set, acceptance is inhibited.
"STOP" .................... Return to step 1
"REC PAUSE" ......... Shift to step 5
*If the focus is disturbed after it has been set, the process returns to step 1.
4. Step 4 Mode (Only focus "OK" can make this item showing)
The CLV servo ON command (8600) sending operation is performed, and the next button input is waited. (The disc is rotated
to perform CLV locking.)

"FF/FWD" ................. The pickup slides toward the outer periphery while this button is held down.
"REW/REV" .............. The pickup slides toward the inner periphery while this button is held down. However, if PU-IN is on, input
is invalid.
"PLAY" ..................... Invalid
"STOP" ..................... Return to step 1
*If the focus is disturbed, the process returns to step 1.
Other cautions
• TOC IL is not executed in the test mode.
• As for button operations other than those shown above, only the sound volume operation (with JOG) is accepted.
3. Tuner Test Mode (TEST 2)
1. Outline of tuner (radio) test mode
The tuner test mode is intended to store the adjustment and measurement frequencies in the preset memory CH without
frequency setting by adjusting personnel when the tuner section is adjusted in the production line.
2. Details of tuner test mode
When the power is turned on by using the POWER ON/STAND-BY button while the BASS/TREBLE and REW/REV buttons
are held down in POWER OFF state, the frequency for adjustment and measurement of destination specified by the AREA
terminal is preset and stored in the preset memory CH. However, Ordinary 1 and Ordinary 2 are set to the designation
(destination selected by SPAN switching operation) set when the test mode is obtained.(Memory/Set+Function Key Span
Charged) (As for frequencies to be preset and stored for each destination, refer to item 3.)
The tuner test mode is started from preset No.1.
The operations of test mode are identical with the ordinary operations of TUNER function. However, FUNCTION switching
is invalid.
Since it is necessary to discard the content of preset memory when the tuner test mode is ended, "0000" or "1111" bits are
written in the memory to be checked in case of memory check (in case of initial setting) so that memory abnormality is detected
in case of initial setting so as to ensure memory initialization.
When the tuner test mode is turned on, the following indication lights for one second.
• The TUNER TEST2 mode is set as a result of BASS/TREBLE+ REW/REV. -> POWER OFF -> IF AC is set to OFF in the TEST2
mode, the initial state is restored.
When POWER is set to OFF, the memory of TEST2 mode is protected.
When the power is turned on again, the ordinary operation is enabled while the data is stored in the
memory (besides TUNER).
If AC OFF state is maintained in this state for about 1/2 day, start is executed in the initial state.
• To clear the whole memory, insert the AC cord, holding down MEMORY + STOP.

4. Electronic volume Test Mode (TEST 3)
When the test mode is set, the following indication lights for one second.
When this mode is set, BASS/TREBLE is set to 0 (0 dB) and start-up function is set to CD when volume is -14 dB (STEP 23).
The button operations in the test mode are the same as those of ordinary operation excepting sound volume UP/DOWN.
(1) The indication is the same as that of ordinary operation excepting test mode setting.
(2) The sound volume control with the sound volume UP/DOWN button is only the following 3 steps unlike the ordinary state.
Volume- ∞ (STEP 0) <-> Volume-14 dB (STEP 23) <-> Volume-0 (STEP 30)
(3) BASS/TREBLE is switched when button operation is performed.
5. Timer test Mode (TEST 4)
When the test mode is set, the following indication lights for one second.
The current time and timer time are set in the following procedure to perform the timer playback.
1.Set the current time to 1:00, set the timer to ON time 1:05, set the function to Aux, and set volume STEP 12. One minute is counted
as one second, and the timer playback operation is performed. The fade-in (when playback is started) is executed at a rate of
one step for 1 sec. After completion of fade-in the fade-out is executed at a rate of one step for 1 sec (WAIT 1 sec inserted). After
completion of fade-out the power is turned off (after WAIT 1 sec), and the mode is changed to the standby mode.
The indication during operation is the same as that of ordinary timer operation.
6. LCD Test Mode (TEST 5)
When the LCD test mode is set, all the LCD segments are lighted. After that the indication is changed as follows according to
the "PLAY" button input.
Lighting of all segments
Lighting of odd segments
– 11 –
Lighting of even segments
XL-55/55C
7. Key input diagnosis Test Mode (TEST 6)
When the test mode is set, the following indication appears.
This test mode is intended to check whether all the main unit buttons can be detected. Accordingly, in this test mode checking as to
whether the "POWER ON/STAND-BY" button was pressed after all the buttons shown below were pressed is performed. If the result
is OK, OK is indicated. Even any one of keys was not pressed, an error is indicated. In case of OK termination or error termination
exit from this mode occurs when the "POWER ON/STAND-BY" button is pressed next time, and the standby mode is set.
1. In case of "MEMORY/SET" + "PLAY"+ "POWER ON/STAND-BY"
Since SURROUND and RDS are not provided, the following 9 buttons are detected as all buttons.
PLAY, POWER ON/STAND-BY, BAND, BASS/TREBLE, FUNCTION, MEMORY/SET, REC PAUSE, REW, FF, STOP.
The OK/NG indication of test result is as follows.

TROUBLESHOOTING
When the CD does not function
When the CD section does not operate when the objective lens of the optical pickup is dirty, this section may not operate. Clean
the objective lens, and check the playback operation. When this section does not operate even after the above step is taken, check
the following items.
Remove the cabinet and follow the troubleshooting instructions.
"Track skipping and/or no TOC (Table Of Contents) may be caused by build up of dust other foreign matter on the laser pickup
lens. Before attempting any adjustment make certain that the lens is clean. If not, clean it as mentioned below."
Turn the power off.
Gently clean the lens with a lens cleaning tissue and a small amount of isopropyl alcohol.
Do not touch the lens with the bare hand.
Dust gradually accumulates on the objective lens during use, and it may degrade performance. To avoid this problem, use a
cleaning disc designed for CD optical pickup lenses.
HOW TO USE
1. Using the brush in the cleaner cap, apply 1 or 2 drops of the cleaning fluid to the brush on the CD cleaner disc which has
the mark next to it.
2. Place the CD cleaner disc onto the CD disc tray with the brush side down, then press the play button.
3. You will hear music for about 20 seconds and the CD player will automatically stop. If it continues to turn, press the stop
button.
CAUTION
The CD lens cleaner should be effective for 30~50 operations, however if the brushes become worn out earller then please
replace the cleaner disc.
If the CD cleaner brushes become very wet then wipe off any excess fluid with a soft cloth.
Do not drink the cleaner fluid or allow it to come in contact with the eyes. In the event of this happening then drink and /
or rinse with clean water and seek medical advice.
The CD cleaner disc must not be used on car CD players or on computer CD ROM drives.
