viRay54 VHF Radio
Antenna Mounting and EME Exposure
This system has a Maximum Permissible Exposure (MPE) Radius of 1.5
meters (per OET Bulletin 65), assuming the maximum power of the radio
and antennas with a maximum gain of 3dBi. Accounting for the height of an
average adult (2 meters) the minimum height of the antenna above the deck
to meet RF exposure compliance requirements is 3.5 meters.
For watercraft with suitable structures, an omnidirectional antenna with gain
not greater than 3 dBi must be mounted a minimum of 3.5 meters vertically
above the main deck and all persons on board. For watercraft without suitable
structures, the antenna must be mounted so as to maintain a minimum of 1.5
meters vertically between the antenna (measured from the lowest point of the
antenna), to the heads of all persons.
Do not transmit when anyone is within the MPE radius of the antenna, unless
shielded from the antenna field by a grounded metallic barrier.
WARNING: Maximum Permissible Exposure
Failure to observe these guidelines may expose those within the
maximum permissible exposure (MPE) radius to RF radiation
absorption that exceeds the FCC MPE limit. It is the radio operator’s
responsibility to ensure that no one comes within this radius.
For optimal radio performance and minimal human exposure to radio
frequency electromagnetic energy, make sure the antenna is:
•connected to the radio before transmitting
•properly mounted
•located where it will be away from people
•located at least 1.5 meters (5 feet) from the radio’s main unit
Safe Compass Distance
Safe Compass Distance is 1 meter for a common mechanical compass; other
compass types may require greater distances. To be sure, you should locate
the radio as far as possible from the compass. Test your compass to verify
proper operation while the radio is also operating.
EMC Conformance
All Raymarine equipment and accessories are designed to the best industry
standards for use in the recreational marine environment. Their design and
manufacture conform to the appropriate Electromagnetic Compatibility
(EMC) standards but correct installation and use is required to ensure that
performance is not compromised.

digital calls. DSC uses a unique Maritime Mobile Service Identity (MMSI)
number to direct DSC calls directly to your radio, much like a telephone
number.When the DSC signal is received, the radio quickly switches over to
channel 70 and performs the corresponding operation.
Note: An MMSI number is required to operate the DSC equipment in this radio. You can program the MMSI number yourself one time only using the
Menu Operation described in this handbook. See My MMSI ID on page 72.
The Ray54 includes the following DSC features:
•Separate receiver dedicated to handling DSC Calls on channel 70
•Position Request function sends GPS position data to or receives position
data from other stations
•Phonebook for automatically making DSC calls
•Quick Save feature saves incoming DSC Calls and the caller’s associated
MMSI number directly into the phonebook
•Quick Call feature sends Individual Calls or Group Calls directly from
the phonebook, just like the redial function on a telephone
•Three (3) Group IDs for making DSC Calls only to stations in your group,
such as a flotilla or fishing fleet
DSC functions are fully described in Chapter 5.

2.2Planning the Installation
When planning the installation of your Ray54, consider the following
conditions to ensure dependable and trouble-free operation.
Mount the main unit to allow easy access from the location where the boat is
normally navigated.
The main unit is designed to be mounted horizontally or vertically on a flat
bulkhead. Select a location that is non-metallic, dry, protected, wellventilated, and free from high operating temperatures and excessive
vibration. Provide sufficient space behind the main unit to allow for proper
cable connections to the rear panel connectors. Locate the main unit as near
as possible to the power source yet as far apart as possible from any devices
that may cause interference such as motors, generators, and other on board
electronics. The radio should be protected from prolonged direct exposure to
rain and salt spray.
The Ray54 is not designed to be mounted in engine compartments. Do not
install the radio in a location where there may be flammable vapors (such as
in an engine room or compartment, or in a fuel tank bay), water splash or
spray from bilges or hatches, where it is at risk from physical damage from
heavy items (such as hatch covers, tool boxes, etc.), or where it might be
covered by other equipment. Locate the radio at least 1.5 meters from the
antenna.
Safe Compass Distance is 1 meter for a common mechanical compass; other
compass types may require greater distances. To be sure, you should locate
the radio as far as possible from the compass. Test your compass to verify
proper operation while the radio is also operating.
Typical Mounting Methods
The Ray54 can be conveniently mounted on a chart table, bulkhead,
overhead, or any other desired location. Refer to the following figure for
typical mounting methods.
Flush Mounting
In addition to the typical Mounting Methods, theRay54 may also be flush
mounted using the optional E46034 Flush Mount Kit. Instructions for
installing the radio using the Flush Mount Kit are included with the kit. These
kits are available from your Raymarine dealer.
Chapter 2: Installation5
Figure 2-1: Typical Mounting Methods
CAUTION: Make sure there are no hidden electrical wires or other items
behind the desired location before proceeding. Check that free access for
mounting and cabling is available.
Figure 2-2: Mounting Dimensions
6Ray54 VHF Radio
2.3Power Connections
The red and black power cord provides connections to DC power. The red (+)
wire is connected to the positive terminal of the power source and contains a
7 amp in-line fuse. The black (-) wire is connected to the negative (ground) of
the power source. Should the power connections be inadvertently reversed,
the unit will not power up but no damage will occur. Check the polarity with
a VOM (Voltage/Ohm Meter) and reconnect observing correct polarity. If the
fuse ever needs replacement, be sure to use the same type and rating.
Connect your Ray54 to the nearest primary source of the boat's DC power. A
typical source may be a circuit breaker on the power panel or a fuse block
near the unit. When connecting to either of these sources, the circuit breaker
or other in-line fuse should be rated at 10 amps.
The power cord should be long enough to reach the DC power source. If
additional wire length is required, the cable can be extended by adding more
cable as necessary. However, for power cable runs longer than 15 feet, larger
wire diameter size should be used to prevent voltage line loss.
To ensure adequate current draw to the equipment, Raymarine recommends
that you use lugs to connect the power cable to the DC supply and that the lug
connections be both crimped and soldered. The connection terminal should
be clean, with no sign of corrosion.
The Ray54 is designed to be operated a on 12 volt system. If battery voltage
drops below 10.5 VDC (approximately), the icon appears on the LCD
(see page 15). You should discontinue using the radio if a low voltage
condition occurs as performance would be unreliable. If voltage exceeds 16
VDC, the message EXCESSIVE VOLTAGE appears on the dot matrix display and
an alarm is sounded. You should immediately disconnect the radio if a high
voltage condition occurs as the unit could become damaged.
Figure 2-3: Wiring Connections
Chapter 2: Installation7
2.4External Speaker Connections
Located just below the power cord is a cable for connection to an optional
external speaker. Connect the white(+) wire and black (–) wire to the speaker
observing polarity as it is marked on the speaker. When connected, the
external speaker will function simultaneously with the internal speaker.
2.5Grounding
While special grounding is not generally required for VHF radiotelephone
installations, it is good marine practice to properly ground all electronic
equipment to the boat’s earth ground system. The Ray54 can be connected to
ground by installing the supplied screw and lock washer in the threaded hole
labelled GND on the main unit’s rear panel just below the antenna jack. Then
attach a wire from this screw to the nearest ship’s earth ground connection
point. The recommended wire to be used for such grounding is #10 AWG.
2.6NMEA Data
The Ray54 accepts NMEA 0183 (V1.5) data from a position determining
device (such as a GPS) to provide the Latitude and Longitude position
information that is transmitted during a DSC Distress Call.
When valid NMEA signal is detected, the GPS indicator appears on the
LCD.When no valid NMEA signal is detected, the NO GPS indicator appears.
Connect the NMEA OUT + and NMEA OUT – signals from the positioning
device to the NMEA IN + (yellow) and NMEA IN – (green) wires in the
radio’s NMEA cable.
An example of how to connect the NMEA cables and power supply using a
suitable connector block is shown in the diagram below. For specific
instructions how to connect your particular GPS, please refer to the
handbook that came with that device.
Figure 2-4: GPS Wiring
8Ray54 VHF Radio
2.7Antenna Connections
The coaxial VHF antenna cable connects to the Ray54 antenna jack on the
rear panel using a PL259 VHF type connector. The antenna cable length can
be critical to performance. If you are uncertain, contact a professional
installer or call Raymarine Product Support. If a longer cable length is
required, RG-8x (50 ohm) marine coaxial cable or equivalent cable can be
used for runs up to a maximum of 50 feet. If the distance required is even
greater, Raymarine recommends using low loss RG-213 or equivalent cable
for the entire run to avoid excessive losses in power output
If the antenna RF connector is likely to be exposed to the marine
environment, a protective coating of grease (Dow Corning DC-4 or similar)
can be applied to the connector 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 Mounting Suggestions
Mounting the VHF antenna properly is very important because it will
directly affect the performance of your VHF radio. Use a VHF antenna
designed for marine vessels.
Since VHF transmission is essentially line-of-sight, mount the antenna at a
location on the vessel that is free of obstruction to obtain maximum range.
If you must extend the length of the coaxial cable between the antenna and
the radio, use a coaxial cable designed for the least amount of power loss over
the entire cable length.
Antenna Mounting and EME Exposure
For optimal radio performance and minimal human exposure to radio
frequency electromagnetic energy, make sure the antenna is:
•connected to the radio before transmitting
•properly mounted
•located where it will be away from people
•located at least 1.5 meters (5 feet) from the radio
