SAFElY PRECAUTIONS
GENERAL GUIDEUNES
1. When servicing, observe the original lead dress. If a short circuit Is found, replace all parts which have been overheated or damaged by the short circuit. 2. After servicing, see to it that all the protective devices such as Insulation barriers, insulation papers shields are properly Installed. 3. After servicing, make the following leakage current checks to prevent the customer from being exposed to shock hazards.
ELECTROSTATICALLY SENSITIVE (ES) DEVICES
Some semiconductor (solid state) devices can be damaged easily by static electricity. Such components commonly are called Electrostatically Sensitive (ES) Devices. Examples of typical ES devices are integrated circuits and some field-effect transistors and semiconductor chip components. The following techniques should be used to help reduce the incidence of component damage caused by static electricity. 1. Immediately before handling any semiconductor component or semiconductor-equipped assembly, drain off any electrostatic charge on your body by touching a known earth ground. Alternatively, obtain and wear a commercially available discharging wrist strap device, which should be removed for potential shock reasons prior to applying power to the unit under test. 2. After removing an electrical assembly equipped with ES devices, place the assembly on a conductive surface such as aluminum foil, to prevent electrostatic charge buildup or exposure of the assembly. 3. Use only a grounded-tip soldering Iron to solder or unsolder ES devices. 4. Use only an anti-static solder removal device classified as anti-static can generate electrical charges sufficient to damage ES devices. 5. Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage ES devices. 6. Do not remove a replacement ES device from its protective package untilimmedlately before you are ready to Install it. (Most replacementES devices are packaged with leads eletcrically shorted together by conductive foam, aluminum foil or comparable conductive material). 7. Immediately before removing the protective materia! from the leads of replacement ES device, touch the protective material to the chassis or circuit assembly Into which the device will be installed. CAUTION : Be sure no power Is applied to the chassis or circuit, and observe all otner asfety precautions. 8. Minimize bodily motions when handling unpackaged replacement ES devices. (Otherwise harmless motion such as the brushing together of your clothes fabric or the lifting of your foot from a carpeted floor can generate static electricity sufficient to damage an ES device).
LEAKAGE CURRENT COLD CHECK
1. Unplug the AC cord and connect a jumper between the two prongs on the plug. 2. Measure the resistance value, with an ohm meter, between the jumpered AC plug and each exposed metallic cabinet part on the equipment such as screwheads connectors, control shafts,etc. When the exposed metallic part has a return path to the chassis, the reading should be between 1M ohm and 5.2 M ohm. When the exposed metal does not have a return path to the chassis, the reading must be oo.
LEAKAGE CURRENT HOT CHECK (See Figure 1)
1. Plug the AC cord directly Into the AC outlet. Do not use an Isolation transformer for this check. 2. Connect a 1.5k ohm, 10 watts resistor, In parallel with a 0.15uF capacitor, between each exposed metallic part on the set and a good earth ground such as a water pipe, as shown In Figure 1. 3. Use an AC voltmeter, with 1000 ohms/Volt or more sensitivity, to measure the potential across the resistor. 4. Check each exposed metallic part, and measure the voltage at each point. 5. Reverse the AC plug in the AC outlet repeat each of the above measurements. 6. The potential at any point should not exceed 0.75 volts RMS. A leakage current tester (Simpson Model 229 equivalent) may be used to make the hot checks, leakage current must not exceed 1/2 milliamp. In case a measurement Is outside of the limits specified, there is a possibility of a shock hazard, and the equipment should be repaired and rechecked before it Is returned to the customer.

[1] JOG mode
In response to the speed at which the inner part dial is turned, the tape can be played back at a speed ranging from still picture to ±1 x normal tape speed. When the turning is stopped, a still picture is always produced.
[2] SHUTILE mode
When the outer part dial is rotated in the SHUTILE mode. the tape speed will be changed depending on the position of the SEARCH/JOG Dial. The tape speed can be changed from 0 (ie, STILL playback) to 9 times the normal tape speed. The still picture is obtained when the SEARCH/JOG Dial is set to the center fix position (click-stop).
10. TV SYSTEM Selector
Used to select the 3 VHS system. PAL: To playback or record by PAL system. CCIR: To playback or record by CCIR system. (S-VHS recording can not be made.) NTSC 4.43: To playback tapes recorded by NTSC system. (Recording cannot be performed.) · · PAL and CCIR systems can not be distinguished automatically. If REC and PLAY Buttons are pressed simultaneously when this selector is set to "NTSC 4.43", the unit will automatically go into playback mode.
Note
· Set the "DIRECT SEARCH" mode in the ON-SCREEN (initial setting) menu to "ON" to perform the direct search operation. (Refer pages 38 to 41.)

In case of dew detection
When condensation (dew, so-called sweating) forms inside the unit, the error message "d" will be displayed on the counter and all the operation buttons are made inoperative. Leave the unit on and let it remain at room temperature until "d" disappears. Depending on the surrounding condition, this may take several hours. Playback picture is distorted.
I
_I ·
Cause of condensation
Condensation forms if warm air comes in contact with a cold object, for example on a window in a well-heated room in winter. may form if the unit or the video cassette is exposed to sudden changes in temperature and humidity such as may occur when the unit or the video cassette is taken from a cold to a warm place. For instance: · In a room where the heater has just been turned on in winter; · In a room with steam or high humidity; · If the unit or the cassette is brought from cold surroundings into a well-heated room
13
Moisture condensation normally occurs gradually. Therefore, there may be cases in which the "d" indicator does not start flashing until 10 or 15 minutes after moisture has begun to condense. In particular, if the temperature or humidity in the room change, wait about 20 minutes before using the unit.
