Notes on chip component replacement
Never reuse a disconnected chip component.
Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.
Flexible Circuit Board Repairing
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.
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. Follo w 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 low­voltage scale. The Simpson 250 and Sanwa SH-63Trd are e x­amples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2 V A C range are suit­able. (See Fig. A)

About CD-Rs/CD-RWs
This CD player can play CD-Rs/CD-RWs recorded in the ATRAC3plus/ATRAC3, MP3 or CDDA* format, but playback capability may vary depending on the quality of the disc and the condition of the recording device.
* CDDA is the abbreviation for Compact Disc
Digital Audio. It is a recording standard used for the Audio CDs.
UNLEADED SOLDER
Boards requiring use of unleaded solder are printed with the lead­free 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)
: LEAD FREE MARK
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.

SER VICING NOTES

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT
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.
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 from more than 30 cm away from the objectiv e lens.
LASER DIODE AND FOCUS SEARCH OPERATION CHECK
During normal operation of the equipment, emission of the laser diode is prohibited unless the upper lid is closed while turning ON the S801. (push switch type) The following checking method for the laser diode is operable.
Method Emission of the laser diode is visually checked.
1. Open the upper lid.
2. Push the S801 as shown in Fig.1.
Note: Do not push the detection lever strongly, or it may be bent or dam-
aged.
3. Press the u button.
4. Check the object lens for confirming normal emission of the
laser diode. If not emitting, there is a trouble in the automatic power control circuit or the optical pick-up. In this operation, the object lens will move up and down 2 times along with inward motion for the focus search.

About ESP (Electronic Shock Protection) function
When a CD is playing, the ESP function is always activated. The ESP function prevents the sound from skipping by using a buffer memory that stores music data for about 10 seconds.
The structure of AT RAC CDs/MP3 CDs
ATRAC CDs/MP3 CDs consist of files and groups. A file is equivalent to a track of an audio CD. A group is a bundle of files and is equivalent to an album. For MP3 CDs, this CD player recognizes an MP3 folder as a group so that ATRAC CDs and MP3 CDs can be operated in the same way.

Notes
¥ If ATRAC3plus/ATRAC3
files and MP3 files are recorded on the same CD, this CD player plays the ATRAC3plus/ATRAC3 only.
¥ The playback capability of
this CD player may vary depending on the quality of the disc and the condition of the recording device.
¥ Acceptable characters on
this CD player are as follows: —A to Z —a to z —0 to 9 —! " # $ % & ’ ( ) * + , - . / :
; < = > ? @ [ \ ] ^ _ ‘ { | }
~ If you use other characters on you computer by using an software such as SonicStage, they are displayed as — on this CD player.
¥ On a disc that has
ATRAC3plus/ATRAC3/ MP3 files, do not save files in other formats and do not make unneccessary groups.
Playing order of AT RAC CDs and M P3 CDs
For ATRAC CDs, files are played in the order selected in SonicStage. For MP3 CDs, the playing order may differ depending on the method used to record MP3 files on the disc. In the following example, files are played in order of 1 to 7.

Notes on ATRAC CDs
¥ Maximum number of groups: 255
Maximum number of files: 999
¥ CD-Rs/CD-RWs recorded in the ATRAC3plus/ATRAC3 format
cannot be played on your computer.
Notes on MP3 CDs
¥ Maximum number of groups: 100
Maximum number of files: 400
Maximum directory level: 8 ¥A group that does not include an MP3 file is skipped. ¥ Be sure to add the file extension mp3 to the file name.
However, if you add the file extension mp3 to a file other than
an MP3 file, the player will not be able to recognize the file
properly. ¥ This player can play bit rates of 16 to 320 kbps, and sampling
frequencies of 32/44.1/ 48 kHz. Variable Bit Rate (VBR) file
can also be played. ¥ To compress a source in an MP3 file, we recommend setting the
compression parameters to 44.1 kHz, 128 kbps, and
Constant Bit Rate. ¥ To record up to the maximum capacity, set the writing software
to halting of writing. ¥ To record to the maximum capacity at one time up on media that
has nothing recorded on it, set the writing software to Disc at
