SAFETY PRECAUTIONS

The following check should be performed for the continued protection of the customer and service technician.

LEAKAGE CURRENT CHECK

Before returning the unit to the customer, make sure you make either (1) a leakage current check or (2) a line to chassis
resistance check. If the leakage current exceeds 0.5 milliamps, or if the resistance from chassis to either side of the
power cord is less than 460 kohms, the unit is defective.

DISASSEMBLY

(Follow the procedure below in reverse order when reassembling)

Note:This system has a feature to back-up various settings such as function selected, volume level, etc. By performing

disassembly or checking of the system, this back-up function can be a cause of error, and the system may not work
normally when power on after re-assembling.
To avoid this error, short-circuit both leads (+ and - terminals) of C110 on 1U-3398-1 (Main PWB) for more than 60
sec., and check that the voltage between the terminals is lowered less than 1V before re-assembling. (The back-up
function is deactivated and various settings are reset to factory settings, default values, if short-circuited.)

NOTE IN HANDLING FOR LASER PICK-UP

Caution for Handling the Laser Pick-up

The laser pick-up is assembled and precisely adjusted using a sophisticated manufacturing process in our plant. Do not
disassemble or attempt to readjust it. Please observe the following instructions carefully in handling the pick-up.

1. Handle with Care

(1) Storage

Do not store the pick-up in dusty, high-temperatured or high-humidity environments.

(2) Please take care for preventing from shock by falling down or careless handling.

2. Protection of the LD

Short a part of the LD circuit by soldering. After connection to a circuit, remove the short solder.

Pick-up

pattern side

Shorting Land

3. Precautions when handling the CD mechanism

 Handle the laser pick-up so that it is not exposed to dust.
 Do not leave the laser pick-up bare. Be sure to cover it.
 If dust adheres on lens of the pick-up, blow it off with a blower brush.
 Do not shock the laser pick-up.
 Do not watch the light of the laser pick-up.

4. Cautions on assembling and adjustment

 Be sure that to the bench, jig, head of soldering (with ceramic) iron and measuring instruments are well grounded.
 Workers who handle the laser pick-up must be grounded.
 The finished mechanism (prior to anchoring in the set) should be protected against static electricity and dust.

The mechanism must be stored so that damaging outside forces are not received.

 When carrying the finished mechanism, hold it by the chassis body.
 For proper operation, storage and operating environment should not contain corrosive gases. For example H

NO2, CL2 etc. In addition storage environment should not have materials that emit corrosive gases especially from
silicic, cyanic, formailn and phenol group. In the mechanism or the set, existence of corrosive gases may cause no
rotation in motor.

CONFIRMATION METHOD OF ADJUSTMENT

In the µcom of this system, there is a built-in function “adjustment confirmation mode” to

check various servo control easily with CD operation buttons.
Also, focus offset, tracking offset, tracking balance, focus gain, and tracking gain are all
adjusted automatically as the digital servo control is built in the system.

1. Activating Adjustment Confirmation Mode

(1) Load the test disc TCD-784 or Mozart (CO-74176) at the function CD.
(2) After pressing the button (PLAY/PAUSE) and button simultaneously, press button (STOP) within 3 sec.

(The adjustment confirmation mode is activated and the track number of the display turns to
Note: Normal control is disabled with the operation buttons when the adjustment confirmation mode is activated.

3. How to Check HF Level

(1) Measuring instruments required

a) Oscilloscope
b) Test disc: TCD-784 (A-BEX) or Mozart (CO-74176)

(2) Attaching connection wire for checking HF level

a) Disassemble 1U-3398-1 (Main PWB) → Refer to “DISASSEMBLY” on page 3, 4.

b) Solder wires to RF and VC test points for connecting the probe of oscilloscope.

(Length of the wires should be less than 20 cm) → Refer to 1U-3398-1 drawing on page 32.

c) Assemble 1U-3398-1, see the diagram below.

(Forwarding connection of segment output terminal.)

in the right figure indicates 1 dot of segment, the figure in shows the segment output

terminal number (00~35) to be connected.

Initialzes internal state of M66004.

Able to communicate with MCU in "L" mode.

Command from MCU will be disregareded in "H" mode.

Shifts input data at rise from "L" to "H".

Inputs character code or command data needed to display from MSB.

Sets oscillation frquency by connecting external resistor and capacitor (maximum

oscillation frequency fosc (max)=1MHz). Also feasible to apply external clock. In this case,

inject external clock to Xin terminal and open Xout terminal.

Connect to digit terminal of VFD. DIG00~DIG15 correspond to the 1st figure to 16th figure

respectively.

Connect to segment terminal of VFD. For corresponding SEG00~SEG35 to segment

terminal of VFD, refer to the figure right.

Output port (static operation).

Positive power supply terminal for internal logic.

Positive power supply terminal for high tension output port.

GND terminal.

Negative power supply terminal for VFD drive.
