IMPORTANT SERVICE NOTES (XL-505 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
pinchedorthathardwareisnotlodgedbetweenthechassis
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.
AllcheckmustberepeatedwiththeAClinecordplugconnection
reversed.
Anyreadingof0.3volt RMS(thiscorresponds to0.2milliamp.
AC.) or more is excessive and indicates a potential shock
hazard which must be corrected before returning the audio
product to the owner.

Precautions for battery use:
Insert the batteries according to the direction indicated in the battery compartment. Replace all old batteries with new ones at the same time. Do not mix old and new batteries. Remove the batteries if they are weak or if the unit is not in use for long periods to prevent potential damage due to battery leakage.
Caution: Do not use rechargeable batteries (nickel-cadmium battery, etc.). Notes concerning use:
Replace the batteries if control distance decreases or operation becomes erratic. Periodically clean the transmitter LED on the remote control and the sensor on the main unit with a soft cloth. Exposing the sensor on the main unit to strong light may in- terfere with operation. Change the lighting or the direction of the unit. Keep the remote control away from moisture, excessive heat, shock, and vibrations.

.................................invalid.
"PLAY".....................Invalid
"STOP" ....................Return to Step 1
Other cautions
• While the CD lid OPEN is detected, entry into any step later than Step 2 is disabled. If CD lid OPEN is detected in any step
higher than Step 2, return to Step 1 is done.
• TOC IL is not performed in the Test Mode.
• The key operation, excepting that specified above, is the same as that of regular operation (CD). Only the FUNCTION key
is input-inhibited.
• Syncro REC with REC key input is also invalid in this mode.
3. Tuner Test Mode (TEST 3)
1. Outline of tuner (radio) Test Mode
The tuner Test Mode is intended to store adjustment/measurement frequency in the preset memory CH without frequency
adjustment by the adjusting personnel when the tuner is adjusted in the production line.
2. Details of tuner Test Mode
When power is turned on with the POWER key while the MEMORY/SET key and BAND key are held down together in
POWER OFF state, the frequency for adjustment/measurement of specific destination specified by the AREA terminal is
preset-stored in the preset memory CH (the frequency to be preset-stored for specific destination is explained in the Item
C). When the tuner Test Mode is started up, it is started with FM. FM is FM STEREO only.
WhentheREWkeyispressedwhilethepresetmemoryCHis1CH,thehighestCHisfoundasincaseofregularmode. When
the FF key is pressed while the preset memory CH is highest CH, 1CH is found.
The RADIO (TUNER) BAND key (or TUNER/BAND key on the remote controller) is valid.
Asincaseofregularmode,selectionofband,FMMONO/STEREOmodeisenabledbypressingtheRADIO(TUNER)BAND
(or TUNER/BAND ) key.
Exiting the tuner Test Mode, When the destruction data is stored in the memory in the tuner Test Mode, AC supply is
interrupted in the Test Mode and the AC supply is recovered, all the memory is cleared with the destruction data in case of
start-up.
(Countermeasures so that the Test Mode memory does not remain when AC supply is restored after power supply failure
occurredonceintheTestMode.) ThememoryisnotclearedwhenACsupplyisturnedoffafterPOWEROFFandFUNCTION
selection. In case of exit from the tuner Test Mode through the backup mode upon occurrence of power failure
the frequency data stored in the preset memory for adjustment/measurement is erased. (As a result the preset
memory CH becomes empty.)
The display indication is the same as that in case of regular operation.
The following display lights for one second when the tuner TEST mode is turned on

• The unit used in the table above is Hz. K represents 1,000 times, and M represents 1,000,000 times.
• The hatched data shown in the table are not stored in the memory.
• FM is stereo mode.
Note: Keys which are effective in Test Mode
• Main unit keys: VOLUME UP/DOWN, BAND, TUNING UP, POWER, MEMORY, CLEAR,
PRESET UP/DOWN
• Remote controller keys: VOL UP/DOWN, BAND, TUNING UP/DOWN, POWER, MEMORY, CLEAR, PRESET UP/DOWN
4. Electronic volume Test Mode (TEST 4)
After the Test Mode is set, the following display lights for one second.
When this mode has been set, -14dB (STEP17) is set, the preset equalizer is set to FLAT (EQ-3), the SRS mode is set to OFF,
and the start-up function is set to Tape.

3. The preset equalizer and SRS are switched if key operation is performed.
5. Timer Test Mode (TEST 5)
When the Test Mode is set, the following display lights for one second.
The current time and timer time are set in the following procedure, and timer playback is performed.
1.Thepresenttimeissetto1:00,thetimerissettoONtime1:02,OFFtime1:12,FunctionissettoTape,VolumeissettoSTEP8.
One minute is counted in increments of second, and timer playback is performed. One step of Fade-in/out in this mode is
performed for 0.5 sec.
The display is the same as that appears in the regular timer operation.
2.Aftercompletionoftimerplaybacktest"TEST-5"indication(whichappearswhenthemodeisset)appearsagainandStandby
state is set. PLAY key entry is waited. If an entry is detected, the SLEEP timer is set to 2 minutes, and Function is set to
Tape, so that playback is started at once. Volume is set to STEP8, and 10 seconds are counted down in decrements of
second. One step of Fade-out is 0.5 sec.
The display is the same as that appears in the regular sleep playback mode.
3. After completion of SLEEP test, the Test Mode is turned off, and regular standby mode is set, so that the Test Mode ends.

6. LCD Test Mode (TEST 6)
When the LCD Test Mode is set, all the LCD segments light.
7. Key input diagnosis Test Mode (TEST A)
When the Test Mode is set, the following display appears.
In this Test Mode checking as to whether all the main unit keys can be detected is performed. Accordingly, when this mode
is set, checking is performed so as to examine whether the POWER key was pressed last after all the following keys were
pressed. If the result is OK, the following OK is displayed. If any one of keys was not pressed, an error is indicated. When the
POWER key is pressed, exit from the mode is made irrespective of whether the termination is normal or abnormal, and the
standby mode is set.
All the models using this microcomputer do not have the same keys. The entry of the following keys is detected depending on
the combination of simultaneously pressed keys when this mode is set. Key pressing order is not fixed. Pressing of all keys
must be detected.
1. In case of "PLAY" + "REC PAUSE"
Since the model does not have RDS and SRS, all the keys to be detected are the following 11 keys.
PLAY, VOL , VOL , BAND, G-EQ, FUNCTION, MEMORY/SET, REC PAUSE, REW/REV, FF/FWD, STOP
OK/NG indication of test result must be as follows.
