HCD-RV7/RV8 SECTION 1 SERVICING NOTES
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 pick-up block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens. LASER DIODE AND FOCUS SEARCH OPERATION CHECK Carry out the "S curve check" in "CD section adjustment" and check that the S curve waveforms is output three times.

When [CD SYNC HI-DUB] button is pressed during recording in function, ALC is turned on. 2. When x button is pressed to stop recording, the tape deck B is selected and tape is rewound, tape is rewound using ­ m button, tape is stops at around the record-starting position and playback of the recorded portion of the tape is started. If the [REC PAUSE/ START] button is pressed for a pause and pressed again to resume recording, when tape deck B is rewound, tape deck B will be rewound until the position where the pause is applied. 3. When [CD SYNC HI-DUB] button is pressed during playback of tape deck B, either normal speed or high speed can be selected by this button. * AMS Test Mode 1. Select the function "TAPE A" or "TAPE B". 2. Select the loop and relay by pressing the [DIRECTION] button. Insert a test tape AMS-110A or AMS-120 to selected tape deck. 3. Press the [SPECTRUM] button to enter the AMS test mode. 4. After a tape is rewound first, the FF AMS is checked, and the mechanism is shut off after detecting the AMS signal twice. 5. Then the REW AMS is checked and the mechanism is shut off after detecting the AMS signal twice. 6. When the check is complete, a message of either OK or NG appears. * To release MC Test mode. 1. To release this mode, press the ?/1 button. 2. The cold reset is enforced at the same time.

[COLD RESET]
· The cold reset clears all data including preset data stored in the RAM to initial conditions. Execute this mode when returning the set to the customer. Procedure: 1. Press three buttons x , [ENTER], and ?/1 simultaneously. 2. The fluorescent indicator tube becomes blank instantaneously, and the set is reset.

[MC TEST MODE]
· This mode is used to check operations of the respective sections of Amplifier, Tuner, and Tape. Procedure: * To enter MC Test Mode 1. Press three buttons of x , [ENTER] and [DISC 3] simultaneously. 2. The messages MUSIC, MOVIE, GAME and P FILE flash on the fluorescent indicator tube. The input FUNCTION is changed to VIDEO. * Check of Amplifier 1. When v button is pressed, GEQ increases to its maximum and a message "GEQ MAX" appears. 2. When V button is pressed, GEQ decreases to its minimum and a message "GEQ MIN" appears. 3. When b or B button is pressed, GEQ is set to flat and a message "GEQ FLAT" appears. 4. When the [VOLUME] knob is turned clockwise even slightly, the sound volume increases to its maximum and a message "VOLUME MAX" appears for two seconds, then the display returns to the original display. 5. When the [VOLUME] knob is turned counter-clockwise even slightly, the sound volume decreases to its minimum and a message "VOLUME MIN" appears for two seconds, then the display returns to the original display. * Check of clock frequency 1. To check the frequency of clock used to run the time in the unit, the clock output is available at IC501 pin el (CLOCK-OUT) on the MAIN board only during MC test mode. 2. The frequency is 32.768 kHz or so.

[VACS ON/OFF MODE]
· This mode is used to switch ON and OFF the VACS (Variable Attenuation Control System). Procedure: 1. Press ?/1 button to turn the set ON. 2. Press the [ENTER] and [GAME MIXING] buttons simultaneously. The message "VACS OFF" or "VACS ON" appears.

[TUNER STEP CHANGE] (EXCEPT Saudi Arabia model)
· A step of AM channels can be changed over between 9 kHz and 10 kHz. Procedure: 1. Press ?/1 button to turn the set ON. 2. Select the function "TUNER", and press [TUNER/BAND] button to select the BAND "AM". 3. Press ?/1 button to turn the set OFF. 4. Press [ENTER] and ?/1 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.

[CD SERVICE MODE]
· This mode can run the CD sled motor freely. Use this mode, for instance, when cleaning the optical pick-up. Procedure: 1. Press ?/1 button to turn the set ON. 2. Select the function "CD". 3. Press three buttons x , [ENTER] , and [OPEN/CLOSE] simultaneously. 4. The CD service mode is selected. 5. With the CD in stop status, press M + button to move the optical pick-up to outside track, or press ­ m button to inside track. 6. To release this mode, press the ?/1 button.
