PANEL MECHANISM DESCRIPTION
A.Panel Opening
1. When Open button(switch) is pressed, the motor (305)
rotates.
2. The rotation of the motor is transmitted forward through
the rack gear (316) via the gears (320-322)
3. When the rack gear (316) moves, the panel (PA1) goes
down.
4. (1) The upper side of the panel pushed on the arm as-
sembly (304) by the pin (✽2) and the groove of the
rail (✽3).
(2) The lock on the lever (A) is let go and the arm assem-
bly (304) goes down.
(3) When this happens, the planetary gear (303) rotates.
5. When the arm assembly goes down to the open position,
the switch (341) is turned on. When the switch (341) is
turned on, the motor stops after 950ms.

B. Closing Behavior
1. The motor rotates in reverse direction.
2. The arm assembly (304) goes up. When the lever (A) goes
into the lock position of the rail (312), the arm assembly
(304) stops going up.
3. When the arm assembly (304) stops, by the rotation of
the planetary gear (303), the motor rotation pushes the
rack gear (316) backward via the gears (320-322).
4. By the close position information of the LPS (342), the
motor (305) stops after 200mS.

C. Angle Behavior

angle is controlled.

D.Assembly (Close Position)
1. Align the arm assembly with the pin of the planetary gear
(303).
2. Assembly these to the sub-chassis (306) along with the
rail (312).
3. Align lever (314) hole and the hold of the chassis (301).
4. Lead wires of LPS should be kept in place with a tape so
that they would not interfere with rack gear (316).

TEST MODE / ADJUSTMENT
■ How to enter the text mode
While pressing on 1 and 3 keys, press the RESET key.
■ Panel Mechanism Adjustment
The mechanism detects the open/close position of the panel
and writes it to the E2PROM.
■ Starting on the test mode
Major initial positions
•
When booted with everything off, the test mode starts up.
• The valueof the volume is –40dB (indication is 15).
• FL lamps all light up.
• The diversity is off.
• Position: All.
• EQ: Flat
• COMPRESSOR: OFF
• SPE/ANA: PEAK HOLD
■ All display lamps lighting up
Since there are many segments on the display section,
bridging with other segments can be confirmed. By track up/
down keys, grids and segments can be lighted up individually.
■
Opening/Closing Time of the Panel Mechanism
When each time the Angle/Retune button is pressed, time
is displayed after going into the tuner mode. From the maximum angle to return, it takes about 1.2S.
■ CD Mechanism Panel Disk Detection
Sensor behavior for detecting whether there is CD disk or
not can be checked. When the sensor is closed off after a
disk is inserted, it beeps four times.
■
FM S-Meter Adjustment (Stop Adjustment and others)
Method:
SG Output: Set to 35dBµ 98.1MHz. (with no modulation)
During the above text mode, when Preset 1 and Preset 6.
are pressed at the same time, the adjustment begins. When
adjustments is completed normally , OK is displayed and there
will be one beep of 2kHz. In this case the stop adjustment
values will be between 15~25dBµ.
When the S-meter value is outside of the standard system
control values, NG is displayed and the initial value of the
system control is written in the E2PROM.
■ AM Stop Adjustment
Method:
SG Output: Set to 35dBµ 999kHz. (with no modulation)
During the above text mode, when Preset 1 and Preset 6.
are pressed at the same time, the adjustment begins. When
adjustments is completed normally , OK is displayed and there
will be one beep of 2kHz. In this case the stop adjustment
values will be between 30~43dBµ .
When the S-meter value is outside of the standard system
control values, NG is displayed and the initial value of the
system control is written in the E2PROM.
[ How to enter the test mode ]
After entering the above-mentioned test mode, switch over
to the tuner mode. Then, press on the TI knob for some time
and the unit will go into panel mechanism test mode, which
is indicated by STAND-BY display.
Method:
Each time Open/Close key (*key) of the remote controller
is pressed, full-open and full-close positions are registered.
(There will be OPEN ENTRY/ CLOSE ENTRY display and
three beeps are sound.)
Releasing:
When TI key is pressed, the unit goes back to the previous
test mode. Pressing the reset key will take the unit to the
initial condition.
■ DOLBY Adjustment
Using the extension cord (W05-0755-00), separate the
mechanism from the unit. Play the TCC-130 and adjust the
test round value to 300mV with the VR1, 2 on the X30 Board.
(Refer to the PC BOARD.) Balance with FWD and REV.
■ Releasing the Security Code
The unit will go into release mode when Preset 6 is pressed
while Preset 1 is being pressed. The character “C” is displayed at the right end of the character display. At this point,
input KCAR by using 1, 2, 3, and 4 key of the remote controller. Confirm with PLAY/PAUSE key and the security code will
be released.
■
The bass boost function of the amplifier can be remote
control from the unit. This is a one-way communication, using one control line. The control is made with pulse widths of
the three kinds of communication data. Five cycle pulses are
generated from the unit side and when there are three consecutive successes, comm unication is established. The pulse
widths are as shown below and the cycle is 200ms.
HI: 100ms
LOW: 70ms
OFF: 40ms
