CAUTION ON REPLACEMENT OF OPTICAL PICKUP

The laser diode in the optical pickup block is so sensitive to
static electricity, surge current and etc., that the components
are liable to be broken down or its reliability remarkably
deteriorated.

PRECAUTIONS

1.Ground for the work-desk.
Place a conductive sheet such as a sheet of copper

(with impedance lower than 10Mohm) on the work­desk and place the set on the conductive sheet so that
the chassis can be grounded.

2.Grounding for the test equipments and tools.

Test equipments and toolings should be grounded in
order that their ground level is the same the ground of
the power source.

㧙

During repair,carefully take the following precautions.
(The following precautions are included in the service
parts.)

3. Grounding for the human body.
Be sure to put on a wrist-strap for grounding whose
other end is grounded.
Be particularly careful when the workers wear
synthetic fiber clothes, or air is dry.

4. Select a soldering iron that permits no leakage and

have the tip of the iron well-grounded.

5. Do not check the laser diode terminals with the

probe of a circuit tester or oscilloscope.

PROTECTION OF EYES FROM LASER BEAM DURING SERVICING

This set employs a laser. Therefore, be sure to follow carefully
the instructions below when servicing.

WARNING!!

SERVICE WARNING : DO NOT APPROACH THE
LASER EXIT WITH THE EYE TOO CLOSELY.

IN CASE IT IS NECESSARY TO CONFIRM LASER
BEAM EMISSION, BE SURE TO OBSERVE FROM
A DISTANCE OF MORE THAN 30cm FROM THE
SURFACE OF THE OBJECTIVE LENS ON THE
OPTICAL PICK-UP BLOCK.

LASER WARNING LABEL

The label shown below are affixed.

1. Warning label

Laser Diode Properties

Material: GaAS/GaALAs
Wavelength: 780nm
Laser output: max. 0.5mW*
Emission Duration: continuous
*This output is the value measured at a distance about 1.8mm

from the objective lens surface on the Optical Pick-up Block.

SERVICE PROCEDURE

1. Replacing the fuses

This symbol located near the fuse indicates that the
fuse used is show operating type, For continued protection against
fire hazard, replace with same type fuse , For fuse rating, refer to
the marking adjest to the symbol.

Ce symbole indique que le fusible utilise est e lent.
Pour une protection permanente, n'utiliser que des fusibles de meme
type. Ce demier est indique la qu le present symbol est apposre.

2. To initialize the unit

1. Press and the hold down the MEMORY button , then press the
After "all lighting " is displayed

2. Press the standby/on button.
After " CLEAR " is displayed, the preset memory and each mode
stored in the memory, are initialized and will return to the
factory settings.

5. Removement of tray

1.Remove the top cover

2.Turn the locked screw to the clockwise to release the lock of gear.

3. Safety-check out

(Only U.S.A. model)
After correcting the original service problem perform the
follwing safety check before releasing the set to the customer
Connect the insulating-resistance tester between the plug of
power supply cord and terminal GND on the back panel.
Specifications: More than 10Mohm at 500V

4. Memory Preservation

This unit does not require memory preservation batteries. A built-in
memory power back-up system preserves the contents of the
memory during power failures and even when the unit is un-plugged.
The unit must be plugged in order to charge the back-up
system.
The memory preservation period after the unit has been unplugged
varies depending on climate and placement of the unit. On the
average, memory contents are protected over a period of a few
weeks after the last time the unit has been unplugged. This pe-riod
is shorter when the unit is exposed to a highly humid cli-mate.

5. Changing the AM band step

With the exception of the worldwide models, a tuning step selector
switch is not provided. When you change the band step, change
the parts as shown below.

Description

CR-305X

Notes)

• PCMD is an MSB first, two's complement output.

• GTOP is used to monitor the frame sync protection status. (High: sync protection window open.)

• XUGF is the frame sync obtained from the EFM signal, and a negative pulse. It is the signal before
sync protection.

• XPLCK is the inverse of the EFM PLL clock. The PLL is designed so that the falling edge of XPLCK
and the EFM signal transition point coincide.

• GFS goes high when the frame sync and the insertion protection timing match.

• RFCK is derived with the crystal accuracy. This signal has a cycle of 136µs (during normal speed).

• C2PO represents the data error status.

• XRAOF is generated when the 16K RAM exceeds the ±4F jitter margin.

Trimming resistor R123

Set the trimming resistors R123 to center.

1. Set the output of the audio oscillator to 1 kHz and 1

2. Connect the oscilloscope and audio oscillator as shown below. (Refer to Fig-1)

3. Load the test disc YEDS-18 on the tray and play the track 2.

4. Adjust the trimming resistor R123 so the signal of channel 2 on the oscilloscope becomes 1.25 times of channel 1.

5. Remove the oscilloscope and audio oscillator.
