SAFETY CHECK-OUT (US model)

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 2V AC range are suitable. (See Fig. A)

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

LASER DIODE AND FOCUS SEARCH OPERATION CHECK

1. Press CD open knob.

2. Open the lid for CD.

3. Push on SWITCH (S701) as following figure.

4. 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 once for the focus search.

Insert a precision screw driver and push SWITCH (S701)

Note

Before playing a file, this player reads all file and folder information on the disc. Depending on the file structure, it may take more than a minute to read them. During this time, TOC READING is displayed.

Tip

You can use the buttons mentioned on page 5 for additional operations in the same way as playing an audio CD.

Press Z PUSH OPEN/CLOSE down to open the CD compartment and place the CD on the CD compartment (see page 4) .

About “MP3”

What is the MP3?

MP3 (MPEG 1 Audio Layer-3) is a standard technology and format for compressing a sound sequence. The file is compressed to about 1/10 of its original size. Sounds outside the range of human hearing are compressed while the sounds we can hear are not compressed.

Playable “MP3” files on this player

You can only play MP3 files recorded by following requirements.

USABLE MEDIA

CD-Rs and CD-RWs

USABLE DISC FORMAT

You can use ISO 9660 Level 1 format discs, not including the expanded format. In some cases, MP3 files that are recorded in a format other than ISO 9660 Level 1 may not play normally or the file and folder names may not be displayed correctly. The major specifications of the ISO 9660 Level 1 format are as follows:

¥ Maximum directory steps: 8 ¥ Usable characters for a file/folder name:

A - Z, 0 - 9, _ (underscore)

¥ Maximum number of characters for a file

name: 12 including quotation marks and a

3-character extension code

Notes

¥ The file names and folder names must be ISO

9660 level 1 compliant.

¥ 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 MP3, the player cannot recognize the file properly and will generate random noise that could damage your speakers.

¥ The file name does not correspond to the ID tag.

THE USABLE NUMBER OF FOLDERS/FILES

¥ Maximum folder number: 255 ¥ Maximum file number: 255

SETTINGS FOR COMPRESSION SOFTWARE AND WRITING SOFTWARE

¥ To compress a source for an MP3 file, we

recommend setting the transfer bit rate of the compression software to 44.1 kHz ,

128kbps , and Constant Bit Rate .

¥ To record up to the maximum capacity, set

to the halting of writing .

¥ To record at one time up to the maximum

capacity on media that has nothing recorded it, set to Disc at Once .

NOTES FOR SAVING FILES ON THE MEDIA

When the disc is inserted, the player reads all the files on that disc. 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. Do not save unnecessary folders or files other than MP3 ones in the disc to be used for MP3 listening.

We recommend that you do not save other types files or unnecessary folders on a disc that has MP3 files.
