To Exposed Metal Parts on Set
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 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. 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)

PRECAUTIONS FOR CHECKING LASER DIODE EMISSINON
To 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-260A)
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.

4. Use the following tools and measuring devices. Check Disc (MD) TDYS-1 (Parts No. 4-963-646-01) TEST DISK (MDW-74/AU-1) (Parts No. 8-892-341-41) Laser power meter LPM-8001 (Parts No. J-2501-046-A) or MD Laser power meter 8010S (Parts No. J-2501-145-A) Oscilloscope (Measure after performing CAL of prove.) Digital voltmeter Thermometer Jig for checking BD board waveform (Parts No. : J-2501-149-A) 5. When observing several signals on the oscilloscope, etc., make sure that VC and ground do not connect inside the oscilloscope. (VC and ground will become short-circuited.) 6. Using the above jig enables the waveform to be checked without the need to solder. (Refer to Servicing Notes on page 7.) 7. As the disc used will affect the adjustment results, make sure that no dusts nor fingerprints are attached to it.

Laser power meter

When performing laser power checks and adjustment (electrical adjustment), use of the new MD laser power meter 8010S (J-2501145-A) instead of the conventional laser power meter is convenient. It sharply reduces the time and trouble to set the laser power meter sensor onto the objective lens of the pick-up.

When to replace batteries
With normal use, the batteries should last for about six months. When the remote no longer operates the deck, replace all the batteries with new ones. CD player or DAT deck, etc.
Do not leave the remote near an extremely hot or humid place. Do not drop any foreign object into the remote casing, particularly when replacing the batteries. Do not expose the remote sensor to direct sunlight or lighting apparatuses. Doing so may cause a malfunction. If you dont use the remote for an extended period of time, remove the batteries to avoid possible damage from battery leakage and corrosion.

Basic Functions of the CONTROL A1 Control System
Automatic function selection
When you connect CONTROL A1 compatible Sony components using CONTROL A1 cables, the function selector on the amplifier (or receiver) automatically switches to the correct input when you press the play button on one of the connected components. (If you press ( (play button) on the MD deck while the CD is playing, the function selector on the amplifier switches from CD to MD.) Notes
This function only works when the components are connected to the amplifier (or receiver) inputs according to the names on the function buttons. Certain receivers allow you to switch the names of the function buttons. In this case, refer to the operating instructions supplied with the receiver. When recording, do not play any components other than the recording source. It will cause the automatic function selection to operate.

Setting the Clock

Once you set the MD decks internal clock, the MD deck will automatically record the date and time of all recordings. When playing a track, you can display the date and time the track was recorded (see page 25). Time on this deck is displayed on a 12-hour clock (USA and Canadian models only) or a 24-hour clock (European model only).

Synchronized recording
This function lets you conduct synchronized recording between the MD deck and selected source component.
With the deck in standby status (the STANDBY indicator lights red), press SCROLL/CLOCK SET down for about 2 seconds until the month (or day) indication in the display starts flashing.

USA and Canadian models

Set the source selector on the amplifier (or receiver) to the source component. Set the source component to pause mode (make sure both the ( and P indicators light together). Set the deck to recording pause mode. Press P on the deck. The source component is released from the pause mode, and recording begins shortly thereafter. When playback ends from the source component, recording stops.

European model

Turn AMS to enter the current month (or day), then press AMS. The month (or day) indication stops flashing, and the day (or month) indication starts flashing.
Do not set more than one component to the pause mode. This MD deck is equipped with a special synchronized recording function that uses the CONTROL A1 Control System (see Making a synchro recording from a CD player connected with a control A1 cable on page 20). You can also make a synchro recording using the Mega CD Control Function via the CONTROL A1 Control System (see Controlling a CD Changer from the MD Deck to Make a Synchro Recording on page 39).

The MD deck uses the SCMS (Serial Copy Management System on page 55)
MDs recorded through digital input connector cannot be copied onto other MDs or DAT tapes through the digital output connector.
When the deck is recording or in recording pause, digital signals input through one of the digital input connectors are output to the respective digital output connector with the same sampling rate
To change the digital input signal to another sampling rate for output (without recording it to an MD), use Input Monitor Function (see page 14).
Useful Tips for Recording
INPUT DISPLAY/CHAR AMS MENU/NO
Monitoring the input signal (Input Monitor)
Before starting recording, you can monitor the selected input signal through the decks output connectors.
Press OPEN/CLOSE to remove the MD. Set INPUT according to the input signal you want to monitor.
When the INPUT is set at ANALOG
TIME OPEN/CLOSE ( p r REC
Checking the remaining recordable time on the MD
Press TIME. When you press the TIME button repeatedly while the deck is stopped, the display alternates between total disc playing time and remaining recordable time on the MD (see page 24). When you press the TIME button repeatedly while recording, the display alternates between the recording time of the current track and the remaining recordable time on the MD.
The analog signal input through the LINE(ANALOG) IN jacks is output to the respective DIGITAL OUT connector after A/D conversion, and then to the LINE(ANALOG) OUT jacks and the PHONES jack after D/A conversion.
When the INPUT is set at OPT1, OPT2 or COAX
After passing through the sampling rate converter, the digital signal input through the respective DIGITAL IN connector is output to the respective DIGITAL OUT connector, and after D/A conversion to the LINE(ANALOG) OUT jacks and PHONES jack.
Changing the display while recording
Each time you press DISPLAY/CHAR (or DISPLAY) while the deck is recording, you can change the display as follows:

Normal display

Press r REC. If the INPUT is set at ANALOG, AD-DA appears in the display. If the INPUT is set at OPT1, OPT2 or COAX, -DA appears in the display.
If Auto Cut appears in the display (Auto Cut)
There has been no sound input for about 30 seconds during recording. The 30 seconds of silence are replaced by a blank of about 3 seconds and the deck changes to recording pause. If the deck continues pausing for about 10 minutes after the Auto Cut Function activated, recording stops automatically. Note that this function does not activate even if there has been no sound input for about 30 seconds when the deck started recording from the blank portion.

Press Recording level display
Press FS (sampling frequency) display
You can turn off the Auto Cut Function
For details, see To turn off the Smart Space Function and Auto Cut Function on page 15. Note that when you turn off the Auto Cut Function, the Smart Space Function is turned off automatically.
