SERVICING NOTES

SAFETY CHECK-OUT
After correcting the original service problem, perform the following
safety check before releasing the set to the customer:
Check the antenna terminals, metal trim, “metallized” knobs, screws,
and all other exposed metal parts for AC leakage.
Check leakage as described below.
LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground and
from all exposed metal parts to any exposed metal part having a
return to chassis, must not exceed 0.5 mA (500 microamperes.).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA
WT-540A. Follow the manufacturers’ instructions to use these
instruments.
2. A battery-operated AC milliammeter. The Data Precision 245
digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a
VOM or battery-operated AC voltmeter. The “limit” indication
is 0.75 V, so analog meters must have an accurate low-voltage
scale. The Simpson 250 and Sanwa SH-63Trd are examples
of a passive VOM that is suitable. Nearly all battery operated
digital multimeters that have a 2 V AC range are suitable. (See
Fig. A)

This appliance is classified as a CLASS 1 LASER product.
The CLASS 1 LASER PRODUCT MARKING is located on
the rear exterior.
Laser component in this product is capable of emitting radiation
exceeding the limit for Class 1.
NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic
breakdown because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic breakdown and also use
the procedure in the printed matter which is included in the repair
parts.
The flexible board is easily damaged and should be handled with
care.
NOTES ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused on
the disc reflective surface by the objective lens in the optical pick-
up block. Therefore, when checking the laser diode emission,
observe more than 30 cm away from the objective lens.
CHUCK PLATE JIG ON REPAIRING
On repairing CD section, playing a disc without the CD lid, use
Chuck Plate Jig.
• Code number of Chuck Plate Jig : X-4918-255-1
Earth Ground

LASER DIODE AND FOCUS SEARCH OPERATION
CHECK
1. Turn ON the [POWER] button.
2. Open the CD lid.
3. Turn on SW2 with screwdriver, etc. as following figure.
4. Press the u (CD) button.
5. Confirm the laser diode emission while observing the objecting
lens. When there is no emission, Auto Power Control circuit
or Optical Pick-up is broken.
Objective lens moves up and down three times for focus search.

WOOFER function works, the ring on the front panel
lights up.
To return to normal sound, press the button repeatedly
until the indication disappears from the display.
Notes
ˎ While the sleeping timer is on, the ring does not light, even if the
WOOFER function is used.
ˎ When you use the headphones, the WOOFER function does not
work.
Playing a CD/MP3 disc
1 Press ì PUSH OPEN/CLOSE Ȱ on the unit, and
place a disc with the label side up on the CD
compartment.
To close the CD compartment, press ì PUSH OPEN/
CLOSE Ȱ on the unit.
2 Press ā on the unit (à on the remote) ȯ.
The unit plays all the tracks/MP3 files once.
When you place MP3 discs, “MP3” appears in the
display after the unit reads the file information.

Tips
ˎ Playback starts from the track/MP3 file you last stopped playing
(Resume play). During stop, the track/MP3 file number to be played
is displayed.
ˎ To cancel the resume play (to start play from the beginning of the
first track/MP3 file), press Ą ȯ while the CD is stopped. When you
open the CD compartment or turn off the unit, the resume play is
also canceled.
Note
You cannot locate a specific track if “SHUF” or “PGM” is lit in the
display.
Press Ą ȯ, and then press MODE ȵ repeatedly until “SHUF” and
“PGM” disappear from the display.
Example of folder structure and playing order
The playing order of the folders and files is as follows:
Folder
MP3 file
Notes on MP3 discs
ˎ When the disc is inserted, the unit reads all the files on that disc.
During this time, “READING” is displayed. If there are many folders
or non-MP3 files on the disc, it may take a long time for play to
begin or for the next MP3 file to start play.
We recommend that you do not save unnecessary folders or files
other than MP3 ones in the disc to be used for MP3 listening.
ˎ A folder that does not include an MP3 file is skipped.
ˎ Maximum number of files: 255
Maximum number of folders: 150 (including the root folder)
Maximum number of folders and files in total: 256
Maximum directory levels: 8
ˎ Folder names and file names can be displayed with up to 30
characters including quotation marks.
ˎ The characters A - Z, 0 - 9, and _ can be displayed on this unit.
Other characters are displayed as “_”.
ˎ This unit conforms to Version 1.0, 1.1, 2.2, 2.3 and 2.4 of the ID3 tag
format. When the file has the ID3 tag information, “song title”, “artist
name” and “album name” can be displayed. If the file does not have
the ID3 tag information, “NO TITLE” appears instead of song title,
“NO ARTIST” appears instead of artist name and “NO ALBUM”
appears instead of album name. The ID3 tag information can be
displayed with up to 15 characters.
ˎ When naming, be sure to add the file extension “mp3” to the file
name.
ˎ If you put the extension “mp3” to a file other than an MP3 file, the
unit cannot recognize the file properly and will generate random
noise that could damage your speakers.
ˎ The file name does not correspond to the ID3 tag.
