FTM-10SR Alignment

Introduction and Precautions

The FTM-10SR has been carefully aligned at the factory for the specified performance

across the 144 MHz and 430 MHz amateur bands. Realignment should therefore not be

necessary except in the event of a component failure. 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.
