FT-2900R Alignment 

Introduction 
The FT-2900R 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 Vertex Standard 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 Vertex Standard 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 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 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. 
 
Required Test Equipment 
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 electrically 
from all other steps. Have all test equipment ready before beginning and, follow all of
