Vertex Standard VX-6000L Alignment Manual

The VX-6000L has been carefully aligned at the factory for the specified performance across
the frequency range specified for each version.
Realignment should therefore not be necessary except in the event of a component failure, or
alteration of version. All component replacement and service should be performed only by an
authorized Vertex Standard representative, or the warranty policy may be voided.
The following procedures cover the sometimes critical and tedious adjustments that are not
normally required once the transceiver has left the factory. However, if damage occurs and
some parts are replaced, realignment may be required. If a sudden problem occurs during
normal operation, it is likely due to component failure; realignment should not be done until
after the faulty component has been replaced.
We recommend that servicing be performed only by authorized Vertex Standard service
technicians who are experienced with the circuitry and fully equipped for repair and
alignment. Therefore, if a fault is suspected, contact the dealer from whom the transceiver was
purchased for instructions regarding repair. Authorized Vertex Standard service technicians
realign all circuits and make complete performance checks to ensure compliance with factory
specifications after replacing any faulty components. Those who do undertake any of the
following alignments are cautioned to proceed at their own risk. Problems caused by
unauthorized attempts at realignment are not covered by the warranty policy. Also, Vertex
Standard must reserve 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 transceiver are clearly
understood, the cause of the malfunction has been clearly pinpointed and any faulty
components replaced, and the need for realignment determined to be absolutely necessary.
The following test equipment (and thorough familiarity with its correct use) is necessary for
complete realignment. Correction of problems caused by misalignment resulting from use of
improper test equipment is not covered under the warranty policy. While most steps do not
require all of the equipment listed, the interactions of some adjustments may require that
more complex adjustments be performed afterwards. Do not attempt to perform only a single
step unless it is clearly isolated electrically from all other steps. Have all test equipment ready
before beginning, and follow all of the steps in a section in the order presented.
