IMPORT ANT SER VICE 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.
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.

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" button while the "Volume/JOG Dial Selector" and "Volume Select"
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 set. (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 Volume Select + POWER. -> 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 + PLAY.
When the following operation buttons are pressed in this sate, the operation is executed as follows.
"POWER".................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" ..................... 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.
5. Step 5 Mode
The CD initialization operation flow is executed to the end, the mute is set to off, and playback is started. Even when the
playback reaches the outermost periphery of disc, the operation does not stop. The LCD display indicates the playback past
time as in case of ordinary CD playback.
Page 16
XL-70/70C

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 SURROUND mode is set to off, and start-up function is set to CD
when volume is -14 dB (STEP 17). 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 and SURROUND are switched when button operation is performed.
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 1:02, set the function to Tape, and set volume STEP 8. 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 0.5 sec. After completion of fade-in the fade-out is executed at a rate of one step for 0.5 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.
5. Timer test Mode (TEST 4)
When the test mode is set, the following indication lights for one second.
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 Lighting of even segments
3. Preset frequencies for various destinations (random preset memory)
• The hatched sections of the table are not stored in memory.

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.
All rights reserved. Unauthorized duplicating, broadcasting and renting this product is prohibited by law.
