Page 2 Important Safety Precautions Prior to shipment from the factory, JVC products are strictly inspected to conform with the recognized product safety and electrical codes of the countries in which they are to be sold. However, in order to maintain such compliance, it is equally important to implement the following precautions when a set is being serviced.
Page 3 Safety Check after Servicing Examine the area surrounding the repaired location for damage or deterioration. Observe that screws, parts and wires have been returned to original positions, Afterwards, perform the following tests and confirm the specified values in order to verify compli- ance with safety standards.

Page 172 8.8.2 LCD viewfinder (1) Outline The LCD viewfinder is an active matrix panel with a diagonal size of 1.1 cm incorporating built-in drivers, which are made using polycrystalline silicon thin film transistors. It is capable of full-color display in both NTSC and PAL formats. It em- ploys the delta array and provides even pictures, which do not present fixed color patterns as in the other arrangements that use the vertical stripe and mosaic arrangements.
