IMPORTANT SAFETY PRECAUTIONS

Product Safety Notice

Some electrical and mechanical parts have special safety-related char acteristics which are often not evi dent from visual inspection, nor can the protection they give necessarily be obtained by replacing them with components rated for higher voltage, wattage, etc. Parts that have sp ecial safety characteristi cs are identified by a ! on schematics and in parts lists. Use of a substitute replacement that does not have the same safety characteristics as the recommended replacement part might create shock, fire, and/or other hazards. The Prod uct’s Safety is under review continuously and new instructions are issued whenever appropriate. Prior to shipment from the factory, our products are carefully inspected to confirm with the recognized product s afety and electrical codes of the countries in which they are to be sold. However, in order to maintain su ch com plian ce, it is equal ly impor tant to implement the following precautions when a set is being serviced.

Precautions during Servicing

A. Parts identified by the ! symbol are critical for

safety. Replace only with part number specified.

B. In addition to safety, other parts and assemblies

are specified for conformance with regulations applying to spur ious rad iation. T hese m ust also be replaced only with specified re pla ce men ts . Examples: RF converters, RF c ables, noise blocking capacitors, and noi se blocking filters, etc.

C. Use specified internal wiring. Note especially:

1)Wires covered with PVC tubing

2)Double insulated wires

3)High voltage leads

D. Use specified insulating materials for hazardous

live parts. Note especially:

1)Insulation tape

2)PVC tubing

3)Spacers

4)Insulators for transistors

E. When replacing AC primary side components

(transformers, power cord, etc.), wrap ends of wires securely about the terminals before soldering.

F. Observe that the wires do not contact hea t produc-

ing parts (heatsinks, oxid e metal fi lm resis tors, fus ible resistors, etc.).

G. Check that replaced wires do not contact sharp

edges or pointed parts.

H. When a power cord has been replac ed, chec k that

5 - 6 kg of force in any direction will not loosen it.

I. Also check areas surrounding repaired locations. J. Be careful that foreign objects (screws, solder

droplets, etc.) do not remain inside the set.

K. Crimp type wire connector

The power transformer uses crimp type connectors which connect the power cord and the primary side of the transformer. When replacing the transformer, follow these steps carefully and precisely to prevent shock hazards. Replacement procedure

1)Remove the old connector by cutting the wires at a point close to the connector.

Important: Do not re-use a connector. (Discard it.)

2)Strip about 15 mm of t he insulation fr om the ends of the wires. If the wires are stranded, twist the strands to avoid frayed conductors.

3)Align the lengths of the wires to be connected. Insert the wires fully into the connector.

4)Use a crimping tool to crimp the metal sleeve at its center. Be sure to crimp ful ly to the complete closure of the tool.

L. When connecting or disconnecting the internal con-

nectors, first, dis connect the AC plug from th e AC outlet.

E1-3-1

Safety Check after Servicing

Examine the area surrounding the repaired location for damage or deterioration. Obse rve that screws, parts, and wires have been returned to their original positions. Afterwards, do the following tests and confirm the specified values to verify compliance with safety standards.

1. Clearance Distance

When replacing primary circuit components, confirm specified clearan ce distance (d) and (d’) between soldered terminals, and between terminals and surrounding metallic parts. (See Fig. 1)

2. Leakage Current Test

Confirm the specified (or lower) leakage current between B (earth ground, power cord plug prongs) and externally exposed accessible parts (RF terminals, antenna terminals, video and audio input and output terminals, microphone jacks, earphone jacks, etc.) is lower than or equal to the specified value in the table below.

Measuring Method (Power ON) :

Insert load Z between B (earth ground, power cord plug prongs) and exposed accessible parts. Use an AC voltmeter to measure acros s the termi nals of l oad Z. See Fig. 2 and the following table.

Instructions for Handling Semi-conductors

Electrostatic breakdown of the semi-conductors may occur due to a poten tial difference caus ed by electrostatic charge during unpacking or repair work.

1. Ground for Human Body

Be sure to wear a ground ing b and ( 1MΩ) that is properly grounded to re m ov e an y sta tic el ec tric it y that may be charged on the body.

2. Ground for Workbench

(1) Be sure to place a conductive sheet or copper plate

with proper grounding (1 MΩ) on the workbench or other surface, where the semi-conductors are to be placed. Because the static electricity charge on clothing will no t escape through the body grounding band, be carefu l to avoid contactin g semi-conductors with your clothing.

ALIGNMENT PROCEDURES OF MECHANISM

The following procedures describe how to align the individual gears and levers that make up the tape loading/unloading mechanism. Since information about the state of the mechanism is provided to the System Control Circuit on ly through the Mode Switch, it is essential that the correct relationship between individual gears and levers be maintained.

All alignments are to be performed with the mechanism in Eject mode, in the sequenc e given. Each

procedure assumes th at all pr evious pro cedures hav e been completed.

IMPORTANT:

If any one of these alignments is not performed

properly, even if off by only one tooth, the unit will

unload or stop and it may result in damage to the

mechanical or electrical parts.

6. P ress CH DOWN button on the unit until the CTL waveform has s hifted from it s original position ( not the position achie ved in step 5, b ut the position of CTL waveform in step 4) by approximately -2ms. Make sure that th e envelope is simply attenuated (shrinks in height) once CTL waveform passes its original position and i s furthe r brough t in the minus direction.

7. S et the Trackin g Control Circui t to the center position by pressing CH UP button and the n “ PLAY ” button.

1-C. Checking/Adjustment of Envelope

Waveform

Purpose:

To achieve a satisfactory picture and precise tracking.

Symptom of Misalignment:

If the envelope out put is poor , noise will appear in the picture. The tracki ng will then lose precision and the playback picture w ill be distorted by any slight v ariation of the Tracking Control Circuit.

1. Co nnect the oscilloscope to TP301 ( C-PB) on the Main CBA. Use TP504 (RF-SW) as a trigger.

2. P lay back the Gray Scale on the Alignment Tape (MH-2). Set the Tracking Control Circuit to the center position by pressing CH UP b utton and then “ PLAY ” button on the unit.

To do this adjustment, turn the top of the Guide Roller with the Guide Roller Adj. Screwdriver.

3. If t he envelope is as shown in Fig. M7, adjust the height of Guide Ro ller [2] (Re fer to Fig. M3) s o that the waveform looks like the one shown in Fig. M9.

4. If t he envelope is as shown in Fig. M8, adjust the height of Guide Ro ller [3] (Re fer to Fig. M3) s o that the waveform looks like the one shown in Fig. M9.

5. W hen Guide Rollers [2] and [3] (Refer t o Fig.M3) are aligned properly, there is no envelope drop either at the beginning or end of track as s hown in Fig. M9.

Note: Upon completion of the adjustment of Guide Rollers [2] and [3] (Refer to Fig. M3), check the X Value by pushing th e CH UP or DOWN b uttons alternately, to check the symm etry of the env elope. Chec k the number of pushe s to ensure cente r position. The number of pushes CH UP button to ac hieve 1/2 level of envelope should m atch the number of pushes CH DOWN button from center. If required, redo the “X Value Alignment.”

1-D. Azimuth Alignment of Audio/Control/

Erase Head

Purpose:

To correct the Azimuth alignment so that the Audio/ Control/Erase Head meets tape tracks properly.

Symptom of Misalignment:

If the position of the Audio/Control/Erase Head is not properly aligned, the Audio S/N Ratio or Frequency Response will be poor.

1. Connect the oscillos cope to the audio output jack on the rear side of the deck.

2. Play back the alignment tap e (MH-2) and confirm that the audio signal output level is 8kHz.

3. Adjust Azimuth Adj. Screw so that the output level on the AC Voltmeter or the waveform on the oscilloscope is at maximum. (Fig. M6)

Standard Notes WARNING

Many electrical and mechanical parts in this chassis have special characteristics. These characteristics often pass unnoticed and the protection afforded by them cannot necessarily be obtained by using replacement components rated for higher voltage, wattage, etc. Replacement par ts that ha ve these sp ecial s afety characteristics are identified in this manual and its supplements; ele ctrical components having such features are identified by the mark " ! " in the schematic diagram and the parts list. Before replacing any of these components, read the parts list in this manual carefully. The use of substit ute replaceme nt parts that do not have the same s afety characteris tics as specified in the parts list may create shock, fire, or other hazards.
