1、1 Specification .2 Exploded View realign- ment should not be done until after the faulty compo- nent 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.

2、 Therefore, if a fault is suspected, contact the dealer from whom the trans- ceiver 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 replaci

3、ng any faulty components. 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 STANDARD must reserve the right to change circuits and alignme

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 co
