LEAKAGE CURRENT CHECK
Plug the AC line cord directly into a 120V AC outlet (do not use an isolation transformer for this check). Use an AC Voltmeter, having 5000 W per volt or more sensitiv­ity. Connect a 1500 W 10 W resistor, paralleled by a
0.15 µF 150V AC capacitor between a known good earth ground (water pipe, conduit, etc.) and all ex­posed metal parts of cabinet (antennas, handle bracket, metal cabinet, screwheads, metal overlays, control shafts, etc.).
READING SHOULD NOT EXCEED 0.3V
Measure the AC voltage across the 1500 W resistor. The test must be conducted with the AC switch on and then repeated with the AC switch off. The AC voltage indicated by the meter may not exceed 0.3 V. A read­ing exceeding 0.3 V indicates that a dangerous poten­tial exists, the fault must be located and corrected. Repeat the above test with the VCR power plug reversed. NEVER RETURN A VCR TO THE CUSTOMER WITHOUT TAKING NECESSARY CORRECTIVE ACTION.

IMPORT ANT PRECAUTIONS
Save Original Packing Materials
The original shipping carton and packing materials will come in handy if you ever have to ship your VCR. For maximum protection, repack the set as it was originally packed at the factory.
Avoid Volatile Liquid
Do not use volatile liquids, such as an insect spray, near the unit. Do not leave rubber or plastic products touching the unit for a long time. They will mar the finish.
Moisture Condensation
Never operate this unit immediately after moving it from a cold location to a warm location. When the VCR is exposed to such a change in temperature, moisture may condense on the cylinder inside, one of its most crucial internal parts. To prevent the VCR from possible damage, do not use the unit for at least 2 hours when there is an extreme or sudden change in temperature.

1) Set “SUMMER TIME (Daylight­Saving Time)”.
IN, daylight-saving time begins on the first Sunday in April. Because the clock automatically changes from 2:00 AM to 3:00 AM (forward one hour), remember that any part of a scheduled Timer Recording that falls between these two times will not be recorded.
OUT, daylight-saving time ends on the last Sunday in October. The VCR clock automatically changes from 2:00 AM to 1:00 AM (back one hour). Therefore, it can affect your recording length if one is set for this time.
2) Set “Time Zone”.
If you select “AUTO” for your time zone, the VCR sets the clock using the first Coordinated Universal Time information it finds. If the time is not correct, select another time zone or use the “MANU” option.
3) Set “CH”.
If you don't know the clock data channel, select “AUTO”. The VCR will scan automatically to tune the channel carrying the clock data.

• Make sure that the tape length is selected correctly according to the tape used on the SET UP screen (page 24).
• When the SLP tape speed is selected and the tape length is not sufficient to record the program to the end, the program cannot be recorded to the end.

1-4-5. Unloading Method of Cassette in Manual
The mechanical deck can not be removed at the condition the cassette is loaded, since one of screws for mounting the mechanism deck with the chassis is located under the cassette. If the cassette can not be unloaded even pressing the (EJECT) button, eject it using the following method.
1. Remove the worm gear holder and the worm gear, and turn the worm wheel (1) to unloading direction shown in Fig. 1-4-5 with a screwdriver etc.
2. When the S, T sliders start unloading, insert a fine driver, etc. into the rectangle hole on the bottom chassis as shown in Fig. 1-4-6 noting that no grease is attached to the tape due to tape slack. Then, turn the worm wheel to wind the tape by turning the pulley (3) of the clutch gear assembly in the arrow direction seeing the mechanical deck from the bottom.
Notes:
• The operation shown in Fig. 1-4-6 should be done with the unit stood up vertically.
• When a cassette is not ejected by turning the worm wheel (1) due to a mechanical operation stop, cut the cassette holding portion shown in Fig. 1-4-7 to eject the tape.
1-4-6. Check Method of Each Operation Mode
without Loading the Cassette
1. Put some tapes on both left and right sides of the cassette holder so that the start/end sensors are not affected by the light. (Fig. 1-4-7)
2. Press the channel up/down keys on the main unit simultaneously for not less than 5 seconds, in succession within 2 seconds after pressing channel up/down keys, press the rewind key of the remote controller.
3. Release both lock levers of the cassette holder to slot in.
4. When a cassette goes down, the rotation speed of the S reel table becomes fast. In this case, if the rotation is stopped, the mechanism starts loading the cassette. (If not stopped, the cassette is ejected.)
5. After loading is carried out, turn the opposite reel table toward the rotating reel table by hand.
6. In this status, the operations in each mode are allowed to carry out.

Note:
• In PLAY or FF/REW mode, the auto eject will be actuated or the power will be turned off if the reel pulse, which is generated by turning the rotating side and opposite side reel tables manually, is not sent.
• Once ejection is actuated, the procedure so far is cleared, therefore when carrying out check again, perform the procedure from the beginning.
• When checking a torque cassette, perform the identical procedure.
• When a tape, guide and capstan are stained with grease, even if a tape is a normal type, its cassette type could not be distinguished, and it could not shift from CUE and REV mode and could not be forwarded and rewound.

<Precautions for Use of T orque Cassette (KT -300NR)>
1. Before loading a torque cassette in a VCR, always remove tape slack. The tape slack can be removed by rotating the reel in the cassette to its take-up direc­tion. (The tape tends to slack since there is no reel brake on the torque cassette.)
2. Do not perform FF and REW operations by using a torque cassette.
3. When the torque cassette is loaded, confirm follow­ing:
1) Make sure the tape does not ride up or over the
No. 8 cap. If it does, do not eject the tape but return the tape to its correct position, taking care not to damage the tape.
2) Make sure the tape is not slackened. If slackened,
operate the VCR in CUE or REVIEW mode and then stop the tape. Then make sure the tape is not slackened again.
3) After above confirmation, proceed to the real
torque adjustment and confirmation.
4. Caution for removal of torque cassette
1) When removing the torque cassette from the VCR,
set the VCR to the STOP mode and w ait for several seconds. Then, make sure the tape is not slackened, and push the EJECT button to remove the cassette.
5. If the previous precautions “1.” to “4.” are not performed properly, the tape may be damaged and correct measurements can not be performed.
6. Do not use worn out or damaged tape, if used they may damage video heads on the cylinder. In such a case always replace the tape with a new one. The replacement tape is of T-120, 10 m in length.

5-5. Waveform and Voltage Measurement

* Measurement of waveform and voltage at each section in the color circuits was conducted with sufficient service color
bar signal being received and reproduced in normal conditions.
* Waveforms and voltage values for the remaining circuit were measured with a broadcasting signal normally received,
so they may vary slightly according to the programs being received. Use them as a measure for servicing.
* All voltage values except the waveforms are expressed in DC and measured by a digital voltmeter.
