4、is not required. Parts List A component whose part code is * cannot be supplied as a service part because one of the following reasons applies. Because it is supplied as an assembled part (under a different part code). Because a number of circuit boards are grouped together and supplied as a single

5、circuit board (under a different part code). Because supply is prohibited due to copyright restrictions. Because reissuance is restricted. Because the part is made to order (at current market price). Circuit Diagram In the circuit diagram, “NIU” is an abbreviation for “Not in Use,” and “UnPop” is an

6、 abbreviation for “Unpopulated.” They both mean non-mounted components. The circuit board and circuit board diagram show silk-screened indications, but no components are mounted.
