1. Precautions 1. Be sure that all of the built-in protective devices are replaced. Restore any missing protective shields. 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.
Precautions 11. High voltage is maintained within specified limits by close-tolerance, safety-related components and adjustments. If the high voltage exceeds the specified limits, check each of the special components. 12. Design Alteration Warning : Never alter or add to the mechanical or electrical design of this unit. Example : Do not add auxiliary audio or video connectors. Such alterations might create a safety hazard. Also, any design changes or additions will void the manufacturer’s warranty. 13.
2. Service Tip 2-1 Replacing The Bulb For The Video Light ✤ The Service materials (Lamp, Plier) will be supplied by SEC Korea. 1. Disassemble the screw from the camcorder with a small screw driver as figure. 1 2. Pull out the video light cover unit carefully as figure. ❚ Do not apply excessive force because the cover is easy to be broken. ❚ The right side of the cover is fixed by hitch, and the left by a screw. 2 3. Pull out the bulb with flat pliers supplied as a service tool.
