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 themarineVHFchannelsavailablein yourRAY53for 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
countriesat the1968International Telecommunication UnionmeetinginGenevaandare
inactiveusearoundthe world.TheUSchannelsarethosechannelsauthorized for use in
the U.S.A. by the FCC.

5.1 DCPower, External SpeakerConnectionsandNMEAInput
The 6 feet longpower cableassemblyconsists of the DC power cable and the
external speaker cable.TheDCpowercableiscomposedof RED(+) and
BLACK(-) wires, and the external speaker cablehasYELLOW(+) and
GREENTHICK(-) wiresandNMEAInputhasGREENTHIN(+)andBROWN(-). The
RED(+) wirewith anin-linefuse(10 amps.) andthe BLACK(-) wire of the 6 pin
connector cable are used for connecting the RAY53to the ship’
s 13.6VDCpower
system.
Inmost cases this length shouldbeadequateenoughto reach the DC power
source.
If additional wirelength is required,the cablecanbeextendedbyaddingmore
cableasnecessary. However,for power cableruns longer than15feet,larger
wirediameter size shouldbeusedtoprevent voltagelineloss.
YourRAY53radio should be connected to the nearest primary source of
ship’
sDCpower. Atypical source may be a circuit breaker on the power
panel or a fuse block near theunit. Whenconnecting to either of these
sources, thecircuit breaker or other in-linefuse shouldberated at 10 amps.
It isrecommendedthat lugs be used to connect thepower cableto the DC
supplyand the lugconnections shouldbeboth crimpedandsoldered. This is
very important in order to insure adequate currect drawto the equipment.
intermittent operation mayresult if aninsufficient connectionismadetothe
power source. the connectionterminal should be clean, with no sigh of
corrosion.
TheRED(+) wireis connected to the positive terminal of the power source or
battery.TheBLACK(-) wire is connected to the negative(ground) of the power
source or battery. Shouldthepower connectionsbeinadvertentlyreversed,the
10amp.in-line fuse locatedin the RED(+) wirewill open. Check the input
power leadsfor correct polaritywithaVOM(volt/ohmmeter),reconnect the
leadsobserving correct polarity,andreplacethe fuse. Use the same rateand
type fuse.
-TheRAY53acceptsNMEA0183data from a GPS or Loran navigator to provide
Lat/Lonposition informationthat is transmit duringDSCDistressCall mode. The
NMEAsentences that couldprovide positional data,by order of priority are:
GGA.RMC,RMA,and GLL.

The coaxial cable to your VHF antenna is intended to be connected to the antenna
jackontherearpanel usingaPL259VHFtypeconnector.Theantennacablemaybe
cut totherequiredlength at installation. If alongercablelengthisrequired,RG-58 50
ohm coaxial cable or equivalent cable may be used for runs up to a maximumof 50
feet. If the distance required is even greater,then we recommend using low loss
RG-213 or equivalent cable for the entire run in order to avoid excessive losses in
power output.
If the antenna RF connector islikelyto be exposed tothemarineenvironment, a
protective coating of grease(similar to Dow Corning DC-4) can be applied to the
connetor before connecting it to the radio. Any other extensions or adapters in the
cable run should also be protected by silicon grease and then wrapped with a
waterproofing tape.

Antenna MoutingSuggestions
Thebest radio in the worldis useless without a good antenna location. Mounting the
VHFantennaproperlyisvery importantbecauseit will directlyaffect theperformance
of your VHF radio. Astandard VHF antenna which is designed to use aboard boats
shouldbeused.
-. Since VHF transmission are essentiallyLine-of-Sight,mount theantenna at the
highest possiblelocationonthe vessel and freeof obstructioninorder to
obtain maximumrange.
-. Use an antennawithhighest possiblegaincharacteristics.
-. If youmust extend the lengthof thecoaxial cablebetweenthe antenna and the
Radio, use a coaxial cabledesignedfor theleast amount of power loss over
the entirecablelength.
-. Keep the coaxial cable betweenthe radio and antennaasshort aspossible.
5.4
Grounding
While special grounding is not generally required for VHF radiotelephone
installations, it is good marine practice to properlyground all electronic equipment to
the ship’
s ground system. The RAY53 can be connected to ground by attaching a
wire to one of the screws on the unit’
s rear panel and then to the nearest ship’
ground connection point. The recommended wire to be used or such grounding is
#10AWG.
RAY53’
s cabinet was specially designed and die-cast from aluminum to insure
maximumnoiserejection fromexternal sources
