1. OPERATION
1.1 INTRODUCTION
Your RAY53 has the capability to transmit and receive on all available US,International and
Canada Marine VHF radiotelephone channels. There are channels that are FCC approved
but may only be used by authorized stations for specific purposes, depending on the type of
vessel (commercial or noncommercial.) Refer to Table 1-1 . These table list all of the marine
VHF channels available in your RAY53 for Canada,International and U.S. radiotelephone
use. Full familiarization with this table is essential when selecting your channels. The
International frequencies were agreed upon by the attending countries at the 1968
International Telecommunication Union meeting in Geneva and are in active use around the
world. The US channels are those channels authorized for use in the U.S.A. by the FCC.
