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.

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.

MP3
(MPEG 1 Audio Layer 3) is a standard format defined by ISO/MPEG which
compresses audio data. MP3 audio tracks must be in MPEG 1 Audio Layer 3 format.
A logical format of files and folders on CD-ROMs, defined by ISO (International Organization for Standardization).
This is a recording method that enables adding of data using the Track-At-Once method. Conventional discs begin at a disc control area called the Lead-in and end at an area called Lead-out. A Multi Session disc is a disc having multiple sessions, with each segment from Lead-in to Lead-out regarded as a single session.

Disassembly
This
mode is used to check the fluorescent indicator tube, LEDs, keys, [MASTER
VOLUME] jog, model, destination and software version.
Procedure
1. Press [SEARCH] button and [OPTIONS] button simultaneously and hold 3 seconds.
2. All LEDs and segments in fluorescent indicator tube will light up.
3. When you want to enter to the software version display mode, press [FLANGER] button. The model information appears at the fluorescent indicator tube. Press [FLANGER] button again to view the destination information.
4. During the destination information display, press [FLANGER] button. Each time [FLANGER] button is pressed, the fluorescent indicator tube shows the version of each category software in the following sequence: SC, MTK (DMB Board firmware version), UI, PF, SYS, CD, CDMA, CDMB, ST, TA, TAS, TM and return back to model information display.
5. When [SEARCH] button is pressed while the version numbers are being displayed except model and destination, the date of the software creation appears. When [SEARCH] button
is pressed again, the display returns to the software version display.
6. Press [ISOLATOR] button, the key check mode is activated.
7. In the key check mode, the fluorescent indicator tube displays “K 0 V0”. Each time a button is pressed, “K” value increases. However, once a button has been pressed, it is no longer taken into account.
“V” value increases in the manner of 0, 1, 2, 3 ... if [MASTER VOLUME] knob is turned clockwise, or it decreases in the manner of 0, 9, 8, 7 ... if [MASTER VOLUME] knob is turned counterclockwise.
8. When [SOUND FLASH] button is pressed after all LEDs and segments in fluorescent indicator tube light up, alternate segments in fluorescent indicator tube and LEDs would light up. If you press [SOUND FLASH] button again, another half of alternate segments in fluorescent indicator tube and LEDs would light up. Pressing [SOUND FLASH] button again
would cause all segments in fluorescent indicator tube and LEDs light OFF. Pressing [SOUND FLASH] button again would cause all segments in fluorescent indicator tube and all LEDs light up.
9. To release from this mode, press the [SEARCH] button and [OPTIONS] button in the same manner as step 1, or disconnect the power cord.
