Precaution 1.Precaution Follow these safety, servicing and ESD precautions to prevent damage and protect against potential hazards such as electrical shock and X-rays. 1-1 SafetyPrecautions 1. Be sure that all of the built-in protective devices are replaced. 2. When reinstalling the chassis and its assemblies, be sure to restore all protective devices, including control knobs and compartment covers. 3. Make sure that there are no cabinet openings through which people--particularly children--might insert fingers and contact dangerous voltages. Such openings include the spacing between the picture tube and the cabinet mask, excessively wide cabinet ventilation slots, and improperly fitted back covers. 4.

Such alterations might create a safety hazard. Also, any design changes or additions will void the manufacturer's warranty. 5. Leakage Current Hot Check (Fig. 1-1): Warning: Do not use an isolation transformer during this test. Use a leakage-current tester or a metering system DEVICE LEAKAGE (READING CURRENT SHOULD NOT BE that complies with American National Standards Institute UNDER TESTER ABOVE 0.5mA) TEST (ANSI C101.1, Leakage Current for Appliances), and TEST ALL Underwriters Laboratories (UL Publication UL1410, EXPOSED METAL SURFACES 59.7). 2-WIRE CORD ALSO TEST WITH With the unit completely reassembled, plug the AC line PLUG REVERSED (USING AC EARTH cord directly into a 120V AC outlet. With the unit's AC ADAPTER PLUG GROUND AS REQUIRED) switch first in the ON position and then OFF, measure the current between a known earth ground (metal water pipe, etc.) and all exposed metal parts.
