•

Never reuse a disconnected chip component.

•

Notice that the minus side of a tantalum capacitor may be

damaged by heat.

•

Keep the temperature of the soldering iron around 270 ˚C

during repairing.

•

Do not touch the soldering iron on the same conductor of the

circuit board (within 3 times).

•

Be careful not to apply force on the conductor when soldering

or unsoldering.

Use of controls or adjustments or performance of procedures
other than those specified herein may result in hazardous radiation
exposure.

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.

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)

The laser diode in the optical pick-up block may suffer electrostatic
break-down because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic break-down 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.

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 from more than 30 cm away from the objective lens.

Boards requiring use of unleaded solder are printed with the lead-
free mark (LF) indicating the solder contains no lead.
(Caution: Some printed circuit boards may not come printed with

the lead free mark due to their particular size)

Unleaded solder has the following characteristics.

•

Unleaded solder melts at a temperature about 40 

°

C higher

than ordinary solder.

Ordinary soldering irons can be used but the iron tip has to be

applied to the solder joint for a slightly longer time.

Soldering irons using a temperature regulator should be set to

about 350 

°

C.

Caution: The printed pattern (copper foil) may peel away if

the heated tip is applied for too long, so be careful!

•

Strong viscosity
Unleaded solder is more viscou-s (sticky, less prone to flow)

than ordinary solder so use caution not to let solder bridges
occur such as on IC pins, etc.

•

Usable with ordinary solder
It is best to use only unleaded solder but unleaded solder may

also be added to ordinary solder.

• 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.

• To cancel the resume play (to start play from the beginning of the 

first track/MP3 file), press   

 in stop mode. The resume play is 

also canceled when you open the CD compartment.

The playing order of the folders and files is as follows:

• 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.

• A folder that does not include an MP3 file is skipped.
• 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

• Folder names and file names can be displayed with up to 30 

characters including quotation marks.

• The characters that can be displayed on this unit are listed below:

– A - Z
– 0 - 9
– _ " $ % ' ( ) * + , – . / \ ` @ |

  Other characters are displayed as “_”.
• 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 ID3 tag information, the song title, 
artist name and album name can be displayed and “ID3” appears 
in the display. If the file does not have ID3 tag information, the 
file name appears instead of the song title, the folder name appears 
instead of the album name and “NO ARTIST” appears instead of 
the artist name. ID3 tag information can be displayed with up to 15 
characters.

• When naming, be sure to add the file extension “mp3” to the file 

name.

• 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.

• The file name does not correspond to the ID3 tag.

Press RADIO•BAND•AUTO PRESET

 “AM”

Hold down TUNE/FOLDER + or – 

 until the 

frequency digits begin to change in the display.

The unit automatically scans the radio frequencies 
and stops when it finds a clear station.
If you can not tune in a station, press TUNE/
FOLDER + or – 

 repeatedly to change the 

frequency step by step.
When an FM stereo broadcast is received, “ST” 
appears.

If the FM stereo broadcast contains noise, press MODE 

 until
