1、1 Specification . 2 Exploded View realignment should not be done until after the faulty component has been re- placed. 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. I

2、f a fault is suspected, contact the dealer from whom the transceiver was purchased for instructions regarding repair. Authorized VERTEX STAN- DARD service technicians realign all circuits and make complete performance checks to ensure compliance with factory specifications after replacing any faulty

3、 compo- nents. Those who do undertake any of the following align- ments are cautioned to proceed at their own risk. Prob- lems caused by unauthorized attempts at realignment are not covered by the warranty policy. Also, VERTEX STAN- DARD reserves the right to change circuits and alignment procedures

4、 in the interest of improved performance, with- out notifying owners. Under no circumstances should any alignment be at- tempted unless the normal function and operation of the transceiver are clearly understood, the cause of the mal- function has been clearly pinpointed and any faulty com- ponents

5、replaced, and realignment determined to be ab- solutely 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 war- ranty policy

6、. 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
