VX-2R Alignment

Introduction

The VX-2R is carefully aligned at the factory for the specified performance across

the amateur band. Realignment should therefore not be necessary except in the
event of a component failure. Only an authorized Yaesu representative should
perform all component replacement and service, or the warranty policy may be
void. The following procedures cover the adjustments that are not normally
required once the transceiver has left the factory. However, if damage occurs and
some parts subsequently 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. 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 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 transceiver are clearly understood, the cause of the
malfunction has been clearly pinpointed and any faulty components replaced, and
realignment determined to be absolutely necessary.

The following test equipment (and familiarity with its 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
