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 pretective 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 manufacturerÕs warranty. 13.
2. Reference Information 2-1 Servicing Jigs and Special Tools 2-1-1 Servicing guide 1. For this VCP chassis, the program switch and the sensors (start/end/reel) are located on the main PCB, not on the deck assÕy. 2. As long as the deck assÕy is connected to the main PCB, all repairs are possible. Important : In order to repair the main PCB without the deck assÕy connected, the X-5 chassis jig should be used. 3.
Reference Information 2-1-4 How to Connect X-5 chassis jig 1. Unplug the power cord from AC outlet. 2. Remove the deck assÕy from main PCB (See Page 4-4 of service manual). 3. To emulate the function of the sensors, plug the power cord to outlet with pressing SW711 on the function PCB (See diagram below). The location of SVC OPTION(SW711) is same on the function PCB regardless of model. Function (Component side) Note : After completing repairs, unplug and plug the power cord in order to reset. 4.
