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-to­ship 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 pos­sible.

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 in­dude “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 be­fore 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.

1) HAIL Volume

Controls the volume level to external loudspeakers connected to the RAY430.

2) Listen Volume

This allows the user to Adjust the RAY430 to the desired listening volume level. When the
control is turned clockwise, the volume level will increase. The volume level decreases when
the control is turned counterclockwise.

3-5

3.3.3 Hail Mode
The mode keys are used to select one of the four operating modes. They are HAIL, FOG, AUX or

INTC.
To operate the RAY430 as a loudhailer, proceed as follows:

1. Press the [HAIL] key.

After pressing the [HAIL] key, the HAIL mode is selected and “HAILER” appears on the
LCD display in the operating mode window. In general, “Hailing” is normally performed
using the forward hailing horn speaker. However, you can select the AFT horn speaker (if
connected) or “Both” or “All” speakers (which includes intercoms) for general ships
announcements.

2. Press the desired speaker key to select the FWD, AFT, BOTH or ALL positions as required

for your particular application. Your selection appears in the speaker station window on the
top right of the LCD display.

3. Press the microphone’s PTT button and speak into the microphone. Now, adjust the HAIL

volume as required using the Hail knob.
In HAIL mode, upon pressing the microphone [PTT] button, “TALK” appears in the speaker

window. Your voice signal is amplified through the microphone and is sent to the selected
external speaker(s).

Releasing the microphone [PTT] button, “TALK” disappears from the speaker station display
window and the speaker station name re-appears.

3.3.4 Intercom Operation

In general, the intercom mode is used to communicate with one of the intercom stations installed on
the vessel. So if intercom operation is desired, you must first:

1. Press the [IC] key. “INTRCOM” will appear on the LCD display in the operating mode

window.

2. Set the STATION ([IC 1/2], [IC3/4]) key to the desired intercom station.

Selection of the desired intercom station by pressing the appropriate station key is the second step in

3-6

operating the intercom mode. Once the station has been selected, communications from the master
station (RAY430 unit) can be enabled.

In the intercom mode, upon pressing the microphone [PTT] button, “TALK” appears in the speaker
station display window. Your voice signal through the microphone is amplified and sent to the
Selected intercom speaker(s).

When the [PTT] button is released, the speaker at the selected station location can act as a
microphone, with sounds being heard at the RAY430 internal speaker or external speaker (if
connected). The RAY430 microphone takes priority over any responses from intercom sub-stations.
This means that the sub-stations cannot be heard if the [PTT] key is held down.

Both the HAIL and LISTEN controls can be adjusted for desired volumes by rotating the Hail or
Listen volume control knobs.

Marking calls from Remote Intercom Stations

As long as RAY430 power is on, the RAY430 master station can be called from any of the Inter-com
sub-stations.

When the [CALL] switch on the sub-station speaker is pressed, both an audible beeping and an LCD
display indicator tell the master station which remote station wishes to communicate with the master
station. At the RAY430 master station, the operator would then select the intercom station key
corresponding to the calling station and speak into the microphone to communicate.

The RAY430 allows you to connect a maximum of four intercom station speakers. The remote
intercom stations cannot communicate directly with each other.

3-7

3.3.5 Fog Horn Mode
The [FOG] key allows the user to alternately select one of the automatic or manual FOG output
signals. There are 9 kinds of alarms. They are: MANUAL, UNDRWY, STOP, SAIL, TOW,
ANCHOR, AGROUND, YELP and ALARM. Whenever the [FOG] key is pressed, the alarm type is
changed in the following order:

A. MANUAL — This lets the hailer serve as a horn for the vessel to permit manual horn signals as

described in the ‘Rules of the Road’ - Section 35.

I. ALARM (Burglar alarm mode)

If an external normally open type switch sensor is attached (not supplied) to the ALM terminal
on the rear panel, this unit can operate as a burglar alarm unit.

When the FOG mode key is pressed until “ALARM” appears on the mode display part and
“BURG” appears on the station display window, the burglar alarm mode is enabled.

Within a few seconds “BURG” disappears and forward horn speaker station name appears.
The Burglar alarm signal is a “warble” type of signal similar to the yelp signal.

When the Burglar alarm mode is selected, the speaker station is changed to FWD, and the HAIL
volume is set to the maximum level automatically.

3-12

The alarm itself is not enabled for five minutes after selection. However, in five minutes, the
characters and backlighting on the LCD display window goes out and only the [FOG] key and
On/Off & Dimmer Control (to Off) are operable on the RAY430. The RAY430 will appear to be
OFE In this condition the burglar alarm will only sound if the ON signal from the external alarm
sensor connected to the ALARM is tripped.

Clearing the ALARM mode

To disable the Burglar alarm mode, press the [FOG] key or turn off the RAY430 by rotating the
On/Off & Dimmer control knob fully counterclockwise.

3.3.6 Aux Mode

If the audio output line from a radiotelephone equipment, cassette deck, or entertainment receiver is
connected to the AUX terminals 1 and 2, the output signals of such units can be amplified through
desired speaker stations by the RAY430.

1. Press the [AUX] mode key which will enable the auxiliary mode.

2. Press the desired speaker station key to select the specific station ([IC 1/2], [IC 3/4]).

3. Adjust the HAIL volume for the desired listening level.

through Listen Volume VR 1.

5. Intercom Selector

Activates the Intercom speaker with selected keyboard or Call key.

6. Output Signal Selector

Select the output signal (Foghorn Signal, Intercom, Alarm or Mic input signal) to the Power
Amplifier

7. Power Amplifier

IC1 is a 30W power amplifier to active the selected speaker.

8. Interface Circuit

Senses the “CALL” or alarm sensor signals from the external unit. The photo couplers are
used to reduce any external noise pickup by isolation.

4-1

9. Input Signal Selector

Selects input signal to active the FWD, AFT, INT, or EXT speaker(s).

10. 10. Tone Generator

Generates a horn and alarm sound for the RAY430. This generator is controlled by the CPU
to produce correct sound patterns and signal timing for various automatic or manual signal
outputs.

11. LCD Driver

U-202 Controls the LCD display.

12. 12. LCD

The LCD is a custom LCD featuring 1 2 characters on a Dot Matrix display. The bar for the
volume and the intercom call numbers are displayed with 16 segment x 8 characters.

13. EL Driver

Drives the EL, controlled by On/Off & Dimmer control knob.

5.2 PREVENTATIVE MAINTENANCE

The procedures listed below for the RAY430 should ideally be performed at monthly intervals to
minimize the possibility of an equipment failure and assure optimum performance.

1. Fuse holders and their connections may be subject to corrosion which can increase circuit

resistance. The in-line fuse should be removed from its holder, inspected and cleaned of any
accumulation of dirt or corrosion.

5-1

2. The unit front panel should be cleaned with a tissue or a soft non-abrasive cloth. Care should

be exercised when cleaning any plastic surface to prevent scratching, especially the LCD
window area. Mild soap and water may be used in stubborn cases. The unit case should be
cleaned of any salt spray or dust as often as necessary.

CAUTION

Do not use solvents or other chemicals for cleaning this equipment.
