Those who do undertake any of the following align- ments are cautioned to proceed at their own risk. Problems caused by unauthorized attempts at re- alignment are

18、 not covered by the warranty policy. Also, Vertex Standard reserves the right to change circuits and alignment procedures in the interest of improved performance, without notifying owners. Under no circumstances should any alignment be attempted unless the normal function and operation of the produc

19、t are clearly understood, the cause of the malfunction has been clearly pinpointed and any faulty components replaced, and realignment deter- mined to be absolutely necessary. The following test equipment (and thorough famil- iarity with its correct use) is necessary for complete realignment. Correc

While most steps do not require all of the equip- ment listed, the interactions of some adjustments may require that more complex adjustments be per- formed afterwards.
