SECTION 4 TEST MODE

4-1. PRECAUTIONS FOR USE OF TEST MODE
1. As loading related operations will be performed regardless of the test mode operations being performed, be sure to check that the disc is stopped before setting and removing it. Even if the (MD) button is pressed while the disc is rotating during continuous playback, continuous recording, etc., the disc will not stop rotating. Therefore, it will be ejected while rotating. Be sure to press the (MD) button after pressing the ^ (CD) button and the rotation of disc is stopped. 2. The erasing-protection tab is not detected in the test mode. Therefore, operating in the recording laser emission mode and pressing the r REC button, the recorded contents will be erased regardless of the position of the tab. When using a disc that is not to be erased in the test mode, be careful not to enter the continuous recording mode and traverse adjustment mode. But CREC MODE, EF MO CHECK and EF MO ADJUST is detect the erasing-protection tab and recording laser power off. 4-1-1. 1. 2. 3. 4. 5. 6.

CAUTION
Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. Notes on chip component replacement Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be damaged by heat. Flexible Circuit Board Repairing Keep the temperature of soldering iron around 270C during repairing. Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). Be careful not to apply force on the conductor when soldering or unsoldering. Laser component in this product is capable of emitting radiation exceeding the limit for Class 1. This appliance is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT MARKING is located on the rear exterior. This caution label is located inside the unit.
SAFETY-RELATED COMPONENT WARNING !! COMPONENTS IDENTIFIED BY MARK ! OR DOTTED LINE WITH MARK ! ON THE SCHEMATIC DIAGRAMS AND IN THE PARTS LIST ARE CRITICAL TO SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY.

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic break-down and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care. NOTES ON LASER DIODE EMISSION CHECK The laser beam on this model is concentrated so as to be focused on the disc reflective surface by the objective lens in the optical pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens. PRODUCT COUNTRY MALAYSIA MALAYSIA MALAYSIA INDONESIA MALAYSIA MALAYSIA MALAYSIA INDONESIA THAILAND MALAYSIA INDONESIA INDONESIA INDONESIA INDONESIA MALAYSIA LASER DIODE AND FOCUS SEARCH OPERATION CHECK Carry out the S curve check in CD section adjustment and check that the S curve waveform is output four times.

Press three buttons p , ENTER/NEXT , and 1/u simultaneously. 2. COLD RESET is displayed on the fluorescent display tube and reset is executed. CD Delivery Mode This mode moves the pick-up to the position durable to vibration. Use this mode when returning the set to the customer after repair. Procedure: 1. Press 1/u button to turn the set ON. 2. Press LOOP button and 1/u button simultaneously. 3. A message LOCK is displayed on the fluorescent indicator tube, and the CD delivery mode is set. MC Hot Reset This mode resets the set with the preset data kept stored in the memory. The hot reset mode functions same as if the power cord is plugged in and out. Procedure: 1. Press three buttons p , ENTER/NEXT , and DISC 1 simultaneously. 2. The fluorescent indicator tube becomes blank instantaneously, and the set is reset. Sled Servo Mode This mode can run the CD sled motor freely. Use this mode, for instance, when cleaning the pick-up. Procedure: 1. Press 1/u button to turn the set ON. 2. Press three buttons p , ENTER/NEXT , and simultaneously. 3. The Sled Servo mode is selected, if CD is blanking on the fluorescent indicator tube. 4. With the CD in stop status, When the 0 AMS ) knob is rotated in the clockwise direction, the pick-up moves outside. When rotated counterclockwise, it moves inside. 5. To exit from this mode, perform as follows: 1) Move the pick-up to the most inside track. 2) Execute MC cold reset. (Press the three buttons p , ENTER/NEXT , and 1/u button simultaneously.) Note: Always move the pick-up to most inside track when exiting from this mode. Otherwise, a disc will not be unloaded. Do not run the sled motor excessively, otherwise the gear can be chipped. Change-over of AM Tuner Step between 9kHz and 10kHz A step of AM channels can be changed over between 9kHz and 10kHz. Procedure: 1. Press 1/u button to turn the set ON. 2. Select the function TUNER, and press TUNER/BAND button to select the BAND AM. 3. Press 1/u button to turn the set OFF. 4. Press ENTER/NEXT and 1/u buttons simultaneously, and the display of fluorescent indicator tube changes to AM 9k STEP or AM 10k STEP, and thus the channel step is changed over. LED and Fluorescent Indicator Tube All Lit, Key Check Mode Procedure: 1. Press three buttons p , ENTER/NEXT , and DISC 2 simultaneously. 2. LEDs and fluorescent indicator tube are all turned on. Press DISC 2 button, and the key check mode is activated. 3. In the key check mode, the fluorescent indicator tube displays K 0 V0 J0. Each time a button is pressed, Kvalue increases. However, once a button is pressed, it is no longer taken into account. J Value increases like 1, 2, 3. if rotating 0 AMS ) knob in + direction, or it decreases like 0, 9, 8. if rotating in - direction. V Value increases like 1, 2, 3. if rotating VOLUME knob in + direction, or it decreases like 0, 9, 8. if rotating in - direction. 4. To exit from this mode, press three buttons in the same manner as step 1, or disconnect the power cord.

Record Bias Adjustment (Deck B) Procedure: INTRODUCTION When set to the test mode performed in Tape Speed Adjustment, when the tape is rewound after recording, the REC memory mode which rewinds only the recorded portion and playback is set. This REC memory mode is convenient for performing this adjustment. During recording, the input signal FUNCTION will automatically switch to VIDEO. (After recording, press the 0 button without stopping will return to the position where recording was started.) 1. Press FUNCTION button to select VIDEO. (This step is not necessary if the above test mode has already been set.) 2. Insert a tape into deck B, press the r REC button, and then press the ( button to start recording. 3. Mode: Record

If these levels do not adjustment level, adjust the RV341 (L-CH) and RV441 (R-CH) on the AUDIO board to repeat steps 3 and 4. Adjustment level: The playback output of 10 kHz level difference against 315 Hz reference should be 1.0 dB. Adjustment Location: AUDIO board
