MANUAL TÉCNICO

VCR-505

1. Before returning the instrument to the customer always make a safety check of the entire instrument including but not limited to the following items.

a. Be sure that no built-in protective devices are defective

and/or have been defeated during servicing (1) Protective shields are provided on this instrument to protect both the technician and the customer. Correctly replace all missing protective shields. including any removed for servicing convenience. (2) When reassembling the instrument be sure to put back in place all protective device including but not limited to nonmetallic control knobs insulating fishpapers adjustment and compartment covers/shields and isolation resistor capacitor networks. Do not operate this instru-

ment or permit it to be operated without all protective devices correctly installed and functioning. Servicers who defeat safety features or fail to perform safety checks may be liable for any resulting damage, and may expose themselves and others to possible injury.

b. Be sure that there are no cabinet openings through which an

adult or child might be able to insert their fingers and contact a hazardous voltage. Such openings include but are not limited to (1) excessively wide cabinet ventilation slots and (2) improperly fitted and/or incorrectly secured cabinet covers.

c. Leakage Cold Check – With the instrument AC plug

removed from any AC source, connect an electrical jumper across the two AC plug prongs. Place the instrument AC switch in the on position. Connect one lead of an ohmmeter to the AC plug prongs tied together and touch the other ohmmeter lead in turn to each push button/customer control exposed metal screws, metalized overlays and to each cable connector. If the measured resistance is less than 1.0 megohm or greater than 5.2 megohm an abnormality exists that must be corrected before the instrument is returned to the customer. Repeat this test with the AC switch in the off position.

AC Leakage Test

d. Leakage Current Hot Check

On completely assembled instrument, plug the AC line cord directly into a 120V AC outlet. (Do not use an isolation transformer during this test). Use a leakage current tester or a metering system that complies with American National Standards Institute (ANSI) C101.1 Leakage Current for Appliances and Underwriters Laboratories (UL) 1410, (59.7).

Measure for current from a known earth ground (metal waterpipe, conduit, etc.) to all exposed metal or conductive parts of the instrument (antenna connections, handle bracket, metal cabinet, screwheads, metallic overlays, push-buttons, control shafts, etc.) especially any exposed metal parts that ofter an electrical return path to the chassis. Any current measured must not exceed 0.5 milliamp. Reverse the instrument power cord plug in the outlet and repeat the test.

ANY MEASUREMENTS NOT WITHIN THE LIMITS SPECIFIED HEREIN INDICATE A POTENTIAL SHOCK HAZARD THAT MUST BE ELIMINATED BEFORE RETURNING THE INSTRUMENT TO THE CUSTOMER OR BEFORE CONNECTING TO ANTENNA OR ACCESSORIES.

e. Interconnected Equipment AC Leakage Test

Avoid shock hazards The instrument, accessory or cable(s) to which this instrument is connected should have the applicable sections of the leakage resistance cold check and the leakage current hot check performed Do not connect this instrument to an antenna cable or accessory that exhibits excessive leakage currents.

2. Read and comply with all caution and safety-related notes on or inside the instrument cabinet and on the chassis.

3. Design Alteration Warning – Do not alter or add to the mechan- ical or electrical design of this instrument. Design alterations and additions, including, but not limited to circuit modifications and the addition of items such as auxiliary audio output connections cables and accessories etc might alter the safety characteristics of this instrument and create a hazard to the user Any design alterations or additions will void the manufacturer's warranty and will make you the servicer responsible for personal injury or property damage resulting therefrom.

4. Observe original lead dress Take extra care to assure correct lead dress in the following areas a near sharp edges b near thermally hot parts – be sure that leads and components do not touch thermally hot parts and c the AC supply Always inspect in all areas for pinched out-of-place or frayed wiring Do not change spacing between components and between components and the printed-circuit board Check AC power cord for damage.

5. Components parts and/or wiring that appear to have overheated or are otherwise damaged should be replaced with components, parts, or wiring that meet original specifications. Additionally determine the cause of overheating and/or damage and if necessary take corrective action to remove any potential safety hazard.

6. PRODUCT SAFETY NOTICE – Many electrical and mechanical parts have special safety-related characteristics some of which are often not evident 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 special safety characteristics are identified in this service data by a star (¡ ) on schematics and a (¡ ) in the parts list. Use of a substitute replacement that does not have the same safety characteristics as the recommended replacement part in this service data parts list might create shock, fire, and/or other hazards. Product Safety is under review continuously and new instructions are issued whenever appropriate. For the latest information, always consult the appropriate current service literature.
