Amplifier section
The
following are measured at AC 120 V - 240 V, 50/60 Hz
Power output (rated): High channel 300 W + 300 W (at 4 Ω, 1 kHz, 1% THD)
Low channel
300 W + 300 W (at 4 Ω, 100 Hz, 1% THD)
RMS output power (reference):
High channel
500 W + 500 W (per channel at 4 Ω, 1 kHz)
Low channel
500 W + 500 W (per channel at 4 Ω, 100 Hz)
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.
REPLACING THE IC102 AND IC4605 ON THE DMB21
BOARD
IC102
and IC4605 on the DMB21 board cannot exchange with single. When these parts on
the DMB21 board are damaged, exchange the entire mounted board.
REPLACEMENT OF THE MS-214 BOARD
When
the MS-214 board is defective, exchange the entire MD (AU) ASSY.

Note: take out the CD mechanism block from a set.
Disassembly
PANEL TEST MODE
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.
COMMON TEST MODE
This
mode is used to check operations of the Amplifier section.
Procedure
To enter Common Test Mode
1. Press [USB/USB SELECT] button and [PRESET EQ] button simultaneously and hold
for 3 seconds.
2. The upper segments of fluorescent indicator tube will blink. The function is changed to TV and the volume
is changed to VOLUME MIN.
Check
of Amplifier
1. Press [PRESET EQ] button repeatedly until a message “GEQ MAX” appears on the
fluorescent indicator tube. GEQ increases to its maximum.
2. Press [PRESET EQ] button repeatedly until a message “GEQ MIN” appears on the
fluorescent indicator tube. GEQ decreases to its minimum.
3. Press [PRESET EQ] button repeatedly until a message “GEQ FLAT” appears on
the fluorescent indicator tube. GEQ is set to flat.
4. When the [MASTER VOLUME] knob is turned clockwise even
slightly, the sound volume increases to its maximum and a message “VOLUME MAX”
appears on the fluorescent indicator tube.
5. When the [MASTER VOLUME] knob is turned counterclockwise even slightly, the
sound volume decreases to its minimum and a message “VOLUME MIN” appears on the
fluorescent indicator tube.
To release from Common Test mode
1. To release from this mode, press POWER button.
2. The cold reset is enforced at the same time.
COLD RESET
The
cold reset clears all data including preset data stored in the EEPROM to
initial conditions. Execute this mode when returning the set to the customer.
Procedure
1. Press the POWER button to turn on the system.

button simultaneously for 3 seconds.
3. “COLD RESET” appears on the fluorescent indicator tube. After that, the fluorescent indicator tube
becomes blank for a while, and the system is reset.
TUNER STEP CHANGE
The
step interval of AM channels can be toggled between 9 kHz and 10 kHz. This mode
is not available for Saudi Arabian, European and Russian models.
Procedure
1. Press POWER button to turn on the system.
2. Press [FUNCTION] button repeatedly to select the “AM”.
