Galaxy DX-73V User Manual

• “Limited” means that we will repair problems caused by factory defects or
normal use at no charge.
• Before returning a radio to us for warranty service, please call our Service
Department for a Repair Authorization Number (RAN). This RAN must be
written below your return address on the outside of the shipping box. Boxes,
which arrive without a RAN, will be refused, and the shipping company will
return the unopened box to you. Be sure to have a pen and paper ready along
with the serial number of your radio before calling. We will give you the RAN
and our shipping address over the phone. The telephone number of the Service
Department is (760) 480-8800, and we suggest calling between 10:00 AM and
4:00 PM Pacific Time.
• Please include a note with a detailed description of the symptoms. This is
important because it will help the technician who works on your radio to locate
your problem. Intermittent problems are easily overlooked, so be sure to give as
much detail as possible in your note. Also, please include your telephone number
in case our technicians have any additional questions.
• Do not send your power cord or microphone unless we ask for these items during
our telephone conversation.
• You are responsible for getting the radio safely to us. (We suggest using United
Parcel Service.) You must pay to ship the radio to us, and we will pay to ship the
radio back to you. Since we use UPS and they do not ship to Post Offices boxes,
please provide us with a street address for the return of your radio.
• We will repair and return your radio as soon as we can. We appreciate your
choosing a Galaxy radio and we want you to be on the air as much as possible!
