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.

INSTALLATION
2.1 UNPACKING AND INSPECTION
Use care when unpacking your new RAY430 from the shipping carton to prevent damage to the
contents. It is also a good practice to save the carton and the interior packing material. The original
packing material should be used in the unlikely event that it becomes necessary in the future to return
the unit for service.

2-2

2.4 PLANNING THE INSTALLATION
When planning the location for your RAY430 to be installed, the following conditions should be
considered to insure dependable and trouble-free operation.
1) The mounting location should be easily accessible to allow easy operation of the front panel
and provide the best viewing angle of the display.
2) There should be adequate ventilation.
3) A sufficient space should be secured behind the unit to allow all cable connections to the rear
panel terminal strip.
4) The mounting place should be located as near to the power source as possible.
5) The selected location should be isolated away from devices that may cause offending noise or
interference, such as motors, steering cables and generators.
6) Generally speaking, the Loudhailer should be protected from prolonged direct exposure to
rain and salt spray. It is a good practice to protect this valuable equipment as much as pos-
sible.
The unit can be conveniently mounted on a chart table, bulkhead, overhead or any other desired
place. (Refer to Figure 2- 1 for typical locations and mounting configurations.)

2.5 ELECTRICAL CONNECTION
Figure 2-4 RAY430 Rear Panel
CAUTION
DO NOT INSTALL THIS RADIO ON VESSELS WITH POSITIVE
GROUND BATTERY SYSTEMS.
2.5.1 DC Power Connections
The RAY430 is intended for use on vessels with 12 VDC power systems and can operate as long as
the DC supply is regulated between 10.8 and 16 VDC.
The input power connections are made at the terminal strip on the rear of the RAY430 unit at the
terminals labeled "13.6V" "+" and "–". See Figure 2-8 on page 2-9 for the exact locations.
2-5

The power leads should normally be routed to the ship’s DC power distribution panel on larger
boats. The RAY430 is fused at 10 amps so connection to a 10 amp or (maximum of) 15 amp circuit
breaker is recommended. On smaller vessels the power leads may be connected directly to the main
battery, isolation switch, or circuit breaker. For best noise isolation from other shipboard electronics
avoid grouping the loudhailer power connections with radar, radio, or echo sounder power leads
together on the same circuit breaker.
Although the RAY430’s power consumption is only 65 watts (maximum), if you find that the power
cable leads need to be extended more than 10 feet, the wire size of the leads should be in-creased
accordingly to minimize line losses. For runs of 20-35 feet #12 AWG is recommended, remember to
always solder all connections on all your power cord additions.
Observe proper polarity! The wire connected to the positive (+) terminal must be connected to the
positive point of the DC power source; The wire connected to the Negative (—) terminal of the
terminal strip must be connected to the negative point of the DC power source. If the power leads are
accidentally reversed, the 10 Amp fuse will blow. If this happens, recheck the polarity of the
connections with a voltmeter (VOM) and, if necessary, reverse the leads for proper connection. Then
replace the 10 amp fuse in the power cord.
2.5.2 Intercom Speaker
Up to four intercom station speakers (optional) can be connected to the intercom speaker terminals
labeled IC1-IC4 on the terminal block. The optional intercom speakers M95998 are 8 ohms and in-
dude “CALL” buttons. Stations 1, 2, 3 and 4, should be connected to the terminal block accordingly
so that they will correspond to the desired Intercom station selections.
Connect one of the speaker lines to terminal 2, the other line to the GND terminal (on the right side
of the terminal block). The “call” line should be connected to the terminal 1.
Figure 2-5
2-6

2.5.3 Hailer Horn(s)
The outside hailer horns should be mounted facing away from the display unit to prevent feedback
problems using the universal swivel mount provided. High gain audio amplifier circuits “hailers” are
susceptible to high frequency audio oscillations (a.k.a. feedback). It is highly recommended that be-
fore permanently mounting the hailing horn, that the HAIL feature is tested with the horn in the
desired location. This should be done to ensure optimum performance. Generally speaking the horn
should be mounted as far away as possible and facing away from the RAY430 base unit. It should be
pointed in the opposite direction of the RAY430 microphone as you are speaking into it.
Connection to the horn(s) should be made with No. 1 8 or larger, stranded, twisted pair copper wire.
The two-conductor cable chosen should be suitable for external all-weather use.
Electrical connections from the deck horn(s) are made on the rear panel terminal strip at either the
FWD or AFT terminal point, depending on the location of the speaker you are connecting.
For connection to FWD, connect the deck horn to terminals “FWD” 1 and 2. For connection to AFT,
connect the deck horn to terminals “AFT’ 1 and 2.
2.5.4 Connection of Burglar Alarm
By connecting an external alarm sensor using a normally open type of switch (not supplied) to the
ALM terminals, this unit can be used as a burglar alarm in the Fog ALM mode (burglar alarm).
When the sensor connected at terminals 1 and 2 (AUX) of this terminal block become shorted
(closed), the alarm function becomes activated and the yelp signal will sound at the maximum
volume through the forward deck hailer horn speaker.
Figure 2-6
2.5.5 Remote Microphone
An external microphone connection is located on the rear panel terminal strip. This may be used if
you desire to operate hailing functions from a secondary station.
2-7

Figure 2-7
2.5.6 Auxiliary Input
Your RAY430 has been designed to allow you to amplify the audio from your VHF radiotelephone
or any other external audio output (i.e. AM/FM radio, CD player) through your intercom or deck
speaker stations. This external audio input can be connected at the auxiliary input terminals 1 and 2.
2.5.7 Connection of an External Speaker
In situations where the main unit is distant from the operator and the noise level is very high, it may
be difficult to hear your RAY430 clearly. By connecting an external (8 ohms, 5 watts or more)
speaker, the sound level can be increased for improved listening capability. When an external
speaker is connected at the external speaker jack, the internal speaker is automatically disconnected.
The connector, a mini phone plug, for the external speaker is supplied with your RAY430 for your
convenience.
