Vertex Standard Co,. Ltd. 

GX1000S Alignment 

 

The 

GX1000S

 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.
