Vertex Standard Co,. Ltd.

CPV350 Alignment

The 

CPV350

 has been carefully aligned at the factory for the specified performance

across the marine band.

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
Standard Horizon 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 Standard Horizon

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 Standard Horizon 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, Standard Horizon, a division of 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.
