SECTION 4

TEST MODE

MD Block

Outline

• In this machine, the overall adjustment mode in which the

automatic adjustments of CD and MO are performed, is established when the machine enters the test mode. In the overall adjustment mode, the loaded disc is identified whether it is CD or MO disc, and the various adjustments are performed in the order as shown below. When a fault is found during the test mode, location of a fault is displayed. In servo mode, the various adjustments are performed automatically too in the order as shown below.

How to enter the test mode

There are two methods to enter the test mode:

1. The method of enter the test mode by shorting the TEST soldering bridge Connect the solder bridge T AP803 (TEST) on the MAIN board by soldering (i.e., connecting IC801 !∞ to GND), and turn on the main power.

2. The method of enter the test mode by pressing the keys While depressing the ( key, press the keys + , + , = , = , + , = , + , = , P , P in this order.

How to exit the test mode

1. When the solder bridge TAP803 is shorted to enter the test mode, turn off the main power and remove soldering from the T AP803 to open the solder bridge.

2. When the machine has entered by pressing the key, turn off the main power of the machine to exit the test mode.

Operation when setting the test mode

When machine enters the test mode, the following initial display appears on LCD and the display changes as described below.

Test mode configuration

Test mode of this machine consists of the following five modes.

ELECTRICAL ADJUSTMENTS

Precautions for Checking Laser Diode Emission

T o check the emission of the laser diode during adjustments, never view directly from the top as this may lose your eye-sight.

Precautions for Use of optical pick-up (KMS-280A/J2N)

As the laser diode in the optical pick-up is easily damaged by static electricity, solder the laser tap of the flexible board when using it. Before disconnecting the connector, desolder first. Before connecting the connector, be careful not to remove the solder . Also take adequate measures to prevent damage by static electricity . Handle the flexible board with care as it breaks easily.

Optical pick-up flexible board

Precautions for Adjustments

1) Use the test mode when performing adjustments. After completing the adjustments, exit the test mode.

2) Use the following tools and measuring devices.

• Check Disc (CD) TDYS-1 (Parts No. 4-963-646-01)

• Pre-recorded MO disc PTDM-1 (Parts No. J-2501-054-A)

• Laser power meter LPM-8001 (Parts No. J-2501-046-A)

• Oscilloscope (Bandwidth 40 MHz or higher. Calibrate the probes before measurement.)

• Digital voltmeter

3) As to power supply, supply DC 3.7V using the BATTERY terminal unless otherwise specified.

4) Switch and control knob position : HOLD switch ....OFF
