IMPORTANT SERVICE NOTES

WARNING :TO REDUCE THE RISK OF FIRE OR ELEC-TRIC SHOCK, DO NOT EXPOSE THIS AP-PLIANCE TO RAIN OR MOISTURE.

RISK OF ELECTRIC SHOCKDO NOT OPEN

CAUTION

CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK. DONOT REMOVE COVER. NO USER-SERVICEABLEPARTS INSIDE. REFER SERVICING TO QUALIFIEDSERVICE PERSONNEL.

This symbol warns the user of uninsulated voltagewithin the unit that can cause dangerous electric shocks.

This symbol alerts the user that there are importantoperating and maintenance instructions in the literatureaccompanying this unit.

This symbol mark means fast operating fuse.For continued protection against risk of fire, replaceonly with same type fuse F901 (1.6A, 125V).

CAUTION:

BEFORE RETURNING THE VIDEO CASSETTERECORDER

Before returning the video cassette recorder to the user,perform the following safety checks.

1. Inspect all lead dress to make certain that leads arenot pinched or that hardware is not lodged betweenthe chassis and other metal parts in the video cassetterecorder.

2. Inspect all protective devices such as non-metalliccontrol knobs, insulation materials, cabinet backs,adjustment and compartment covers or shields, isola-tion resistor/capacitor networks, mechanical insula-tors etc.

3. To be sure that no shock hazard exists, check forcurrent in the following manner.

● Plug the AC line cord directly into a 120 volt AC outlet(Do not use an isolation transformer for this test).

● Using two clip leads, connect a 1.5k ohm, 10 wattresistor paralleled by a 0.15µF capacitor in series withall exposed metal cabinet parts and a known earthground, such as a water pipe or conduit.

● Use an SSVM or VOM with 1000 ohm per volt, orhigher, sensitivity or measure the AC voltage dropacross the resistor (See Diagram).

● Move the resistor connection to earth exposed metalpart having a return path to the chassis (antenna,metal cabinet, screw heads, knobs and control shafts,

ADJUSTMENT OF TAPE DRIVE TRAIN1. Tape run rough adjustment

1 Remove the cassette housing control assembly.2 After shortcircuiting TP801 provided at the center

(facing to the main PWB), plug in the power cord.3 Check and adjust the position of the tension pole.

(See page 18.)4 Check and adjust the video search rewind back

tension. (See page 17.)5 Connect the oscilloscope to the test point for PB

CHROMA envelope output (TP201). Set the syn-chronism of the oscilloscope to EXT. The PBCHROMA signal is to be triggered by the headswitching pulse (TP202).

6 Set the alignment tape (VROATSV) to play. (Put a500g weight on the cassette tape to prevent lift ofcassette tape.)

Notes:1. Previously set the tracking control in the center position,

and adjust the envelop waveform to maximum with Xvalue adjustment nut. Thereby the tape run rough ad-justment is facilitated.

2. Especially the outlet side envelope waveform must havehigher flatness.

Figure 4-32.

2. Adjustment of A/C head height and azimuth1 Perform the initial setting of A/C head position by the

method stated in "Page 20 Replacement 3".2 Connect the oscilloscope to the audio output termi-

nal.3 Using the alignment tape in which 1 kHz linear audio

signal has been recorded, adjust the height screw soas to get max audio output.

4 Using the alignment tape in which 7 kHz linear audiosignal has been recorded, adjust the azimuth screwso as to get max audio output.

7 Press the tracking button (+), (–) and change theenvelope waveform from max to min and from min tomax. At this time make sure that the envelopewaveform changes nearly parallel.

8 Unless the envelope waveform changes nearly par-allel, adjust the height of supply side and take-upside guide roller so that the envelope waveformchanges nearly parallel. (For envelop adjustmentprocedure refer to Figure 4-35.)

9 Turn the tilt screw to remove the tape crease at thefixing guide flange.Play back the tape and check for tape crease at thefixing guide flange.(1) If there is no tape crease

Turn the tilt screw clockwise so that tape creaseappears once at the flange, and then return the tiltscrew so that the crease disappears.

(2) If there is tape creaseTurn counterclockwise the tilt screw so that thetape crease disappears.(Reference) If the tilt screw is turned clockwisecrease appears at the lower flange.

2 Rough adjustment of X valueTentatively fix A/C head arm screws 1 and 2 by themethod described in Page 20 "Replacement 3".Play back the alignment tape (VROATSV)(VC-H982U), and shortcircuit TP802. As a result the auto-tracking is automatically cancelled, so that the Xvalue adjustment mode is set.Move the A/C head with the X value adjustment geardriver (JiGDRiVER-6) by the method shown in Fig-ure 4-33, and adjust the A/C head so as to get themaximum envelope waveform. (Note: When the A/Chead is adjusted, adjust so that the maximum en-velop waveform is obtained nearest the position ofinitial setting made in Page 20.)

2 Playback the alignment tape (VROEFZCS), andshortcircuit TP802. As a result the auto-tracking isautomatically cancelled, so that the X value adjust-ment mode is set.

3 Move the A/C head with the X value adjustment geardriver by the method shown in Figure 4-33, andadjust the A/C head so as to get the maximumenvelope waveform. (Note: At this time adjust so asto get the maximum envelope waveform nearest theA/C head position which has been set in case of Xvalue rough adjustment as stated in Page 23, 3- 2.)

4 Tighten finally the screws 1 and 2. Be sure totighten at first the screw 1 and then the screw 2.

Final tightening torque is 0.6N·m (If the screw 2 istightened first, the X value may deviate.)

5 Adjust the playback switching point (Refer to theelectric adjustment method.)

6 Playback the self-picture-recorded tape, and checkthe flatness of envelope waveform and sound.
