Vertex Standard Co., Ltd.
VXR-9000U-A Alignment
The VXR-9000U 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 STANDSRD 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.
