PANEL MECHANISM DESCRIPTION

A. Panel Opening

1. When Open button(switch) is pressed, the motor

(PM1) rotates.

2. The rotation of the motor is transmitted forward

through the rack gear (616) via the gears (620~622)

3. When the rack gear (616) moves, the panel (PA1)goes

down.

4. (1) The upper side of the panel pushed on the arm

assembly (604) by the pin (]2) and the groove of

the rail (]3).

(2) The lock on the lever (A) is let go and the arm

assembly (604) goes down.

(3) When this happens, the planetary gear (603) ro-

tates.

5. When the arm assembly goes down to the open po-

sition, the switch (PS1) is turned on.When the switch

(PS1) is turned on, the motor stops after 950ms.

B. Closing Behavior

1. The motor rotates in reverse direction.

2. The arm assembly (604) goes up.When the lever (A)

goes into the lock position of the rail (612), the arm

assembly (604) stops going up.

3. When the arm assembly (604) stops, by the rotation

of the planetary gear (603), the motor rotation pushes

the rack gear (616) backward via the gears (620~622).

4. By the close position information of the LPS (VR1),

the motor (PM1) stops after 200mS.

C. Angle Behavior

1. By the position information of the LPS (VR1), the

panel angle is controlled.

PANEL MECHANISM DESCRIPTION

D. Assembly (Close Position)

1. Align the arm assembly with the pin of the planetary

gear (603).

2. Assembly these to the sub-chassis (606) along with

the rail (612).

3. Align lever (614) hole and the hold of the chassis

(601).

4. Lead wires of LPS should be kept in place with a tape

so that they would not interfere with rack gear (616).

TEST MODE / ADJUSTMENT

■How to enter the text mode

While pressing on 1 and 3 keys, press the RESET key.

■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, bridg-

ing with other segments can be confirmed.By track up/down

keys, grids and segments can be lighted up individually.

■

Opening/ClosingTime of the Panel Mechanism

When each time the Angle/Retune button is pressed, time

is displayed after going into the tuner mode. From the maxi-

mum 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 35dBµ98.1MHz. (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 sys-

tem control is written in the E2PROM.

■AM Stop Adjustment

Method:

SG Output: Set to 35dBµ999kHz. (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 sys-

tem control is written in the E2PROM.

■Panel Mechanism Adjustment

The mechanism detects the open/close position of the panel

and writes it to 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.

(Therewillbe OPEN ENTRY/ CLOSE ENTRYdisplayand 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 theVR1, 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 dis-

played at the right end of the character display. At this point,

input KCAR by using 1, 2, 3, and 4 key of the remote control-

ler. Confirm with PLAY/PAUSE key and the security code will

be released.

■

Specifications for the Amplifier ControlTerminal

The bass boost function of the amplifier can be remote con-

trol 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 suc-

cesses, communication is established.The pulse widths are

as shown below and the cycle is 200ms.

HI: 100ms

LOW: 70ms

OFF: 40ms

CAUTION : For continued safety, replace safety

critical components only with manufacturer's rec-

ommended parts (refer to parts list).

!

Indicates safety critical components. To re-

duce the risk of electric shock, leakage-current or

resistance measurements shall be carried out

(exposed parts are acceptably insulated from the

supply circuit) before the appliance is returned to

the customer.

•DC voltages are as measured with a high

impedance voltmeter. Values may vary slightly

due to variations between individual instru-

ments or/and units.
