General information

Service

This product has been factory aligned and tested to specification 

before shipment. In normal circumstances, the transceiver will 

operate in accordance with these instructions. All adjustable trim-

mers, coils, and resistors in the transceiver were preset at the 

factory. They should only be readjusted by a qualified technician 

who is familiar with this transceiver and has the necessary test 

equipment. Attempting service or alignment without factory auth-

orization can void the transceiver warranty. 
When operated properly, the transceiver will provide years of service 

and enjoyment without requiring further realignment. The information 

in this section gives some general service procedures requiring little 

or no test equipment.

Include your telephone number, fax number, and e-mail address (if 

available) along with your name and address in case the service 

technician needs to call you for further information While investi-

gating your problem. Do not return accessory items unless you feel

You may return this product for service to the authorized 

 

dealer from whom you purchased it, or any authorized 

 

service center. A copy of the service report will be returned with the
