The VX-6000 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 Yaesu 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 Yaesu 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 Yaesu 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, Yaesu 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.
