When recording from a CD player or MD deck connected to a DIGITAL IN connector, the deck marks track numbers in the same sequence as the source. When recording from other sources connected to the DIGITAL IN connector or a source connected to the ANALOG IN jacks, do the procedure below to mark track numbers automatically. However, you cannot mark track numbers automatically if the sound source to be recorded is noisy (e.g., tapes or radio programs).

You can set the level at any value between 72 dB and 0 dB, in 2 dB increments.
Tips for automatic track marking
When recording from a CD player or an MD deck connected to the DIGITAL IN connector, the entire material might be recorded as a single track in the following cases: When you consecutively record the same track two or more times using single-track repeat play. When you consecutively record two or more tracks with the same track number but from different CDs or MDs. When you record tracks from certain CD or multi-disc players. A track number might not be marked for tracks less than 4 seconds long (in Stereo mode, Monaural mode, and LP2 Stereo mode) or 8 seconds long (in LP4 Stereo mode) during recording. When recording from a component connected to the ANALOG IN jacks with T.Mark Off selected or when recording from a DAT deck or DBS tuner connected to the DIGITAL IN connector, the entire material may be recorded as a single track. When recording from a DAT deck or DBS tuner connected to the DIGITAL IN connector, the deck will mark a track number whenever the sampling frequency of the input signal changes, regardless of the track marking parameter setting (T.Mark Lsync or T.Mark Off).

Auto Cut: When the Smart Space function is on, if there is no sound input for 30 seconds or more, the MD deck replaces this silence with a blank of about 3 seconds and enters recording pause.

Precautions

On safety Should any solid object or liquid fall into the cabinet, unplug the deck and have it checked by qualified personnel before operating it any further. Caution The use of optical instruments with this product will increase eye hazard. On power sources Before operating the deck, check that the operating voltage of the deck is identical with your local power supply. The operating voltage is indicated on the nameplate at the rear of the deck. The unit is not disconnected from the AC power source (mains) as long as it is connected to the wall outlet, even if the unit itself has been turned off. If you are not going to use the deck for a long time, be sure to disconnect the deck from the wall outlet. To disconnect the AC power cord, grasp the plug itself; never pull the cord. AC power cord must be changed only at the qualified service shop. On condensation in the deck
If you have any questions or problems concerning your deck, please consult your nearest Sony dealer.

Note on MDs

Do not touch the internal disc directly. Forcing the shutter open may damage the internal disc. Be sure to stick the labels supplied with the MD to the appropriate positions. The shape of the labels may vary depending on the MD brand.
Proper location of the labels

Shutter

Where to keep the MDs
Do not place the cartridge where it may be exposed to direct sunlight or extremely high heat and humidity.

Regular maintenance

Wipe dust and debris from the surface of the cartridge with a dry cloth.
If the deck is brought directly from a cold to a warm location, or is placed in a very damp room, moisture may condense on the lenses inside the deck. Should this occur, the deck may not operate properly. In this case, remove the MD and leave the deck turned on for several hours until the moisture evaporates.

On cleaning

System limitations
The recording system in your deck is radically different from those used in cassette and DAT decks and is characterized by the limitations described below. Note, however, that these limitations are due to the inherent nature of the MD recording system itself and not to mechanical causes.
Disc Full appears in the display even before the MD has reached the maximum recording time
Clean the cabinet, panel and controls with a soft cloth slightly moistened with a mild detergent solution. Do not use any type of abrasive pad, scouring powder or solvent such as alcohol or benzine.

System limitations (continued)
You can make only a first-generation copy2) through a digital-to-digital connection.

Examples are as follows:

The deck does not play.
You can make a copy of a commercially available digital sound program (for example, a CD or MD), but you cannot make a second copy from the first-generation copy. You can make a copy of a digital signal from a digitally recorded analog sound program (for example, an analog record or a music cassette tape) or from a digital satellite broadcast program, but you cannot make a second copy from the first-generation copy.
2) A first-generation copy means the first recording of a digital audio source through the decks digital input connector. For example, if you record from a CD player connected to the DIGITAL IN connector, that copy is a firstgeneration copy.
Moisture has formed inside the deck. Take the MD out and leave the deck in a warm place for several hours until the moisture evaporates. The deck is not on. Press ?/1 to turn on the deck. The deck may not be connected to the amplifier correctly. Check the connection (page 6). The MD is inserted in the wrong direction. Slide the MD into the disc slot with the label side up and the arrow pointing toward the slot (page 16). The MD may not be recorded. Replace the disc with one that has been recorded.
The sound has a lot of static.
Strong magnetism from a television or a similar device is interfering with operations. Move the deck away from the source of strong magnetism.
The deck does not record.
The restrictions of the Serial Copy Management System do not apply when you make a recording through the analog-to-analog connections.

Troubleshooting

If you experience any of the following difficulties while using the deck, use this troubleshooting guide to help you remedy the problem. Should any problem persist, consult your nearest Sony dealer.
The deck does not operate or operates poorly.
The deck is not connected properly to the program source. Check the connection (page 6). Select the correct program source using INPUT. The recording level is not adjusted properly. Adjust the recording level (page 12). A premastered MD is inserted. Replace it with a recordable MD. There is not enough time left on the MD. Replace it with another recordable MD with fewer recorded tracks, or erase unnecessary tracks (page 19). There has been a power failure or the AC power cord has been disconnected during recording. Data recorded to that point may be lost. Repeat the recording procedure.

Disc Full

, Set the deck in a stable surface, and repeat the recording procedure. The inserted MD is dirty (with smudges, fingerprints, etc.), scratched, or substandard in quality. , Replace the disc and repeat the recording procedure.

C13/Read Error

ELECTRICAL PARTS LIST. 62
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 the 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. SAFETY CHECK-OUT After correcting the original service problem, perform the following safety check before releasing the set to the customer: Check the antenna terminals, metal trim, metallized knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below. LEAKAGE TEST The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500 microamperes.). 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. Follow 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 AC voltmeter. The limit indication is 0.75 V, so analog meters must have an accurate lowvoltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2 V AC range are suitable. (See Fig. A)
