SAFETY CHECK-OUT
(US model only)
After correcting the original service problem, perform the following safety checks before releasing the set to the customer: Check the antenna terminals, metal trim, “metallized” knobs, screws, and all other exposed metal parts for A C leakage. Check leakage as described below.
LEAKAGE
The A C leakag e from any exposed metal part to earth g round and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500 microampers). Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA WT -540A. Follo w the manufacturers’ instructions to use these instruments.
2. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a VOM or battery-operated A C voltmeter . The “limit” indication is 0.75 V, so analog meters must ha ve an accur ate lo w-v oltage scale. The Simpson 250 and Sanwa SH-63Trd are e xamples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2V AC range are suitable. (See Fig. A)

ATTENTION AU COMPOSANT AYANT RAPPORT
À LA SÉCURITÉ! LES COMPOSANTS IDENTIFÉS P AR UNE MARQUE 0 SUR LES DIAGRAMMES SCHÉMA TIQUES ET LA LISTE DES PIÈCES SONT CRITIQUES POUR LA SÉCURITÉ DE FONCTIONNEMENT. NE REMPLACER CES COMPOSANTS QUE PAR DES PIÈSES SONY DONT LES NUMÉROS SONT DONNÉS DANS CE MANUEL OU DANS LES SUPPÉMENTS PUBLIÉS PAR 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.
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.

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 270˚C 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.

TEST MODE

HCD-DP700
[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 STOP , DISPLAY , and DISC 1
simultaneously.
2. The fluorescent indicator tube becomes blank instantaneously,
and the set is reset.
[T uner Step Change] (Except for European and Middle Eastern models)
• A step of AM channels can be changed o ver between 9 kHz and 10 kHz.
Procedure:
1. Press POWER button to turn the set ON.
2. Select the function “TUNER”, and press TUNER/BAND button
to select the BAND “AM”.
3. Press POWER button to turn the set OFF.
4. Press ENTER and POWER buttons simultaneously, and the
display of fluorescent indicator tube changes to “ AM 9 k STEP” or “ AM 10 k STEP”, and thus the channel step is changed ov er .
[Function Change Mode]
• Select either VIDEO or MD of the external FUNCTION input.
Procedure:
1. Turn on the power.
2. Hold down MD(VIDEO) button then press POWER button,
and release POWER button f irst in order not in switch off the set immediately. The another function of the previous function is selected, the input level is also changed and displayed “MD” or “VIDEO”.
[GC Test Mode]
• This mode is used to check the software version, FL tube, LED, keyboard and VACS.
Procedure:
1. Press three buttons STOP , DISPLAY , and DISC 2
simultaneously.
2. LEDs and fluorescent indicator tube are all turned on.
3. When you want to enter the software version display mode,
press DISC 1 .The model number and destination are displayed.
4. Each time DISC 1 is pressed, the display changes stating from
MC version, GC version, CD version, CDDM, CDMA, CDMB, BDA, BDB, ST version, TA version, TM version, TC version, in this order, and returns to the model number and destination display.
5. When DISC 3 is pressed while the version numbers are being
displayed except model number and destination, year, month and day of the software creation appear . When DISC 3 is pressed again, the display returns to the software version display . When DISC 1 is pressed while year, month and day of the software creation are being displayed, the year, month and day of creation of the software versions are displayed in the same order of version display.
6. Press DISC 2 button, and the key check mode is activated.
7. In the key check mode, the fluorescent indicator tube displays
“KOJOVO”. Each time a button is pressed, “KEY” value increases. However, once a button is pressed, _it is no longer taken into account. “VOL” value increases lik e 1, 2, 3...if rotating VOLUME knob in “+” direction, or it decreases like 0, 9, 8...if rotating in “_”direction.
8. Also when DISC 3 is pressed after lighting of all LEDs and FL
tubes, value of VACS appears.
9. T o exit from this mode, press three b uttons in the same manner as step 1, or disconnect the power cord.
[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 the POWER button t turn on the set.
2. Press the three buttons of STOP , DISPLAY and DISC 3 simultaneously.
3. Cursor segment flash on the FL display tube. The input FUNCTION is changed to GAME.
* Check of Amplifier
Initial settings: Input , GAME

Output channel switching:
MUSIC key: L , LR , R through MOVIE key: L , SL R , SR through GAME key:L , L, SL, C R , R, SR, SW through TOOL key: L , CR , SW through
1. When the VOLUME control knob is turned clockwise even slightly, the sound volume increases to is maximum and a message “VOLUME MAX” appears for two seconds, then the display returns to the original display.
2. When the V OLUME control knob is tuned 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.
* Tuner function
1. In the test mode, the default-preset channel is called even when the TUNER is selected and an attempt is made to call the preset channel that has been stored in memory. (It means that the memory is cleared.)
2. The minimum, center and maximum frequency of each band is set then.
* Tape recording test
1. To enter the MC Test Mode.
2. Load tapes in both tape decks A and B.
3. Press the REC button to start recording.
4. Pressing the M/+ , m/– buttons during recording returns the tape to the recording start position and stops it at this position.
5. Pressing the “High Speed Dubbing” key while playing back the tape of deck B switches the playback speed between “Normal Speed” and “High Speed”.
Note:
When the playback direction of the tape is set to other than “ONY WAY”, the restriction on the number of times playback which can be repeated will be cleared.
* AMS Test Mode
1. Set TAPE function
2. Select the desired loop by pressing the PLAY MODE button. Insert a test tape AMS-110A or AMS-120 to Deck A.
