Notes on chip component replacement
Never reuse a disconnected chip component.
Notice that the minus side of a tantalum capacitor may be
damaged 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.
CAUTION
Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.
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 leakag e 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 A C 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 A C voltmeter . The “limit” indication is 0.75 V, so analog meters must have an accurate low-v oltage 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)

SERVICING NOTES

ZS-H10CP/H20CP
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 pick­up block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens.
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.

Example of folder structure and playing order
The playing order of the folders and files is as follows:
Notes on MP3 discs
• 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.

Note:
1. CD Block is basically constructed to operate without adjustment.
2. Use PATD-012 disc (Part No. 4-225-203-01) unless otherwise indicated.
3. Use an oscilloscope with more than 10 M impedance.
4. Clean the object lens by an applicator with neutral detergent when the signal level is low than specified value with the following checks.
5. Check the focus bias check when optical pick-up block is replaced.
FOCUS BIAS CHECK
FM T rac king Adjustment
Procedure :
1. Connect oscilloscope to TP (RFA CO) and TP (VC) on the CD board.
2. Press the [POWER] button to turn the power on.
3. Set the disc (PATD-012) and press the u button to playback.
4. Confirm that oscilloscope waveform is as sho wn in the figure below. (eye pattern) A good eye pattern means that the diamond shape () in the center of the waveform can be clearly distinguished.
