GENERAL DESCRIPTION
1.1 INTRODUCTION
Congratulations on your purchase of the RAY430 Multifunction Loudhailer.
The RAY430 Loudhailer is a multipurpose device that may be used as a ship-to-shore hailer, ship-to-
ship hailer, foghorn, audio amplifier, intercom, and/or alarm system.
As a loudhailer, the RAY430 amplifies your voice up to a 30 watt level, for hailing through the
hailing horn speaker, and when listening for replies, amplifies the incoming sounds to the desired
listening level. If an additional (optional) horn is added to the system, the loudhailer output can be
switched to either or both of the hailing horn positions by the front panel control.
To verify your ownership and warranty registration, you should take a few minutes and fill out your
warranty registration card found just inside the front cover of this manual. It is very important that
you take the time to fill this card out. The warranty registration card should be returned to the factory
immediately after your purchase in order to receive full warranty benefits.
Section 5 in this manual provides further information on obtaining Customer Service and Product
Support which is available to you as a valued customer.
1.2 EQUIPMENT FEATURES
The RAY430 is designed and manufactured to provide ease of installation and operation with
excellent reliability. Some of the important built-in features of the equipment are listed below.
The loudhailer horns(s) are used as sound dispersal points when the RAY430 is used as a foghorn so
that the full 30 watt output of the unit can be employed.
In the foghorn mode any of six programmed foghorn patterns can be automatically generated. They
are: Underway, Stopped, Sail, Tow, Anchored, and Aground.
INTERCOM — Provides 2-way communication between the display unit and up to 4 connected
remote units, which can also originate a call to the display unit.
AUXILIARY MODE — Allows the selective or simultaneous transmission of an external audio
input to all stations. For entertainment, the external audio can be a cassette deck, radio, or CD player.
For business, it can also be any other instrument having an external audio output, such as the output
from a VHF or SSB radiotelephone.
