8、naldesign be modified or altered without permission from PHILIPS ElectronicsCorporation. All components should be replaced only with types identical tothose in the original circuit and their physical location, wiring and lead dressmust conform to original layout upon completion of repairs.Special co
9、mponents are also used to prevent x-radiation, shock and fire haz-ard. These components are indicated by the letter “x” included in their compo-nent designators and are required to maintain safe performance. No deviationsare allowed without prior approval by PHILIPS Electronics Corporation.Circuit d
10、iagrams may occasionally differ from the actual circuit used. This way,implementation of the latest safety and performance improvement changesinto the set is not delayed until the new service literature is printed.CAUTION: Do not attempt to modify this product in any way. Never performcustomized ins
11、tallations without manufacturers approval. Unauthorized modi-fications will not only void the warranty, but may lead to property damage oruser injury.Service work should be performed only after you are thoroughly familiar withthese safety checks and servicing guidelines.GRAPHIC SYMBOLSThe exclamatio

14、ST RISKOF FIRE, REPLACE ALLFUSES WITH THE SAME TYPE ANDRATING AS MARKED NEAR EACH FUSE.SERVICE INFORMATIONWhile servicing, use an isolation transformer for protection from AC line shock.After the original service problem has been corrected, make a check of the fol-lowing:FIRE AND SHOCK HAZARD1. Be s
15、ure that all components are positioned to avoid a possibility of adjacentcomponent shorts. This is especially important on items trans-ported to andfrom the repair shop.2. Verify that all protective devices such as insulators, barriers, covers, shields,strain reliefs, power supply cords, and other h
16、ardware have been reinstalledper the original design. Be sure that the safety purpose of the polarized lineplug has not been defeated.3. Soldering must be inspected to discover possible cold solder joints, soldersplashes, or sharp solder points. Be certain to remove all loose foreign par-ticles.4. C
17、heck for physical evidence of damage or deterioration to parts and compo-nents, for frayed leads or damaged insulation (including the AC cord), andreplace if necessary.5. No lead or component should touch a high current device or a resistor ratedat 1 watt or more. Lead tension around protruding meta
18、l surfaces must beavoided.6. After reassembly of the set, always perform an AC leakage test on allexposed metallic parts of the cabinet (the channel selector knobs, antennaterminals, handle and screws) to be sure that set is safe to operate withoutdanger of electrical shock. DO NOT USE A LINE ISOLAT
19、ION TRANS-FORMER DURING THIS TEST. Use an AC voltmeter having 5000 ohms pervolt or more sensitivity in the following manner: Connect a 1500 ohm, 10watt resistor, paralleled by a .15 mfd 150V AC type capacitor between aknown good earth ground water pipe, conduit, etc.) and the exposed metal-lic parts
20、, one at a time. Measure the AC voltage across the combination of1500 ohm resistor and .15 mfd capacitor. Reverse the AC plug by using anon-polarized adaptor and repeat AC voltage measurements for eachexposed metallic part. Voltage measured must not exceed 0.75 volts RMS.This corresponds to 0.5 mill
21、iamp AC. Any value exceeding this limit consti-tutes a potential shock hazard and must be corrected immediately.TIPS ON PROPER INSTALLATION1. Never install any receiver in a closed-in recess, cubbyhole, or closely fittingshelf space over, or close to, a heat duct, or in the path of heated air flow.2
22、. Avoid conditions of high humidity such as: outdoor patio installations wheredew is a factor, near steam radiators where steam leakage is a factor, etc.3. Avoid placement where draperies may obstruct venting. The customershould also avoid the use of decorative scarves or other coverings thatmight o
