Installation (To be carried out by a qualified Marine or
Automotive Electrician only)
a. Receiver
The Seasafe Receiver may be operated either in-hand (portably) or via
the dash-mount cradle. If using the cradle, you should select a position on the vessel where the receiver
will be clearly visible to the skipper, protected from direct sunlight (if possible) and protected from direct
exposure to moisture (rain, spray, breaking waves etc). The cradle should be attached to the vessel dashboard or bulk head via two self tapping screws (preferably stainless steel). Two appropriate sized holes
should be drilled and the cradle attached by the use of the two self-tapping screws. Once the cradle has
been attached to the vessel, the receiver can be slid into position. The receiver can be removed from the
cradle at any time and either operated in-hand or even removed from the vessel for portable operation. If
the receiver is to be used outside of the cradle, ensure that the omni-directional antenna is plugged into
the receiver in order for the device to receive emergency transmitter signals. The only time the omnidirectional antenna should be unplugged is when an alarm has been received and the directional-antenna
has been plugged into the unit in order to “search’ for the source of the alarm. When a search has been
6
completed, the receiver should be returned to stand-by mode and the omni-directional antenna should be
plugged into the unit once more. For portable operation, the receiver batteries will need to be fully
charged. The batteries are automatically charged when the receiver is connected to the vessel 12 VDC
power supply. Batteries are installed by the Seasafe dealer upon purchase of the equipment and are not
replaceable by the user. Whilst the receiver is connected to the vessel’s power it will run off this power
source at the same time the internal batteries will be charged. When disconnected from the vessel’s
power source, the receiver will operate off the internal battery supply.

b. Power / Auxiliary Output Cable
The receiver is supplied with a connection cable and plug. The cable consists of three wires.
A red ‘positive’ power connection wire, a black ‘negative’ connection wire and a white ‘auxiliary’ output
connection wire. Connection of the Seasafe Receiver Power and Auxiliary Output cable should only be
performed by a qualified marine or automotive electrician. The red wire is supplied with an in-line fuse
which will protect the receiver in the event of a short-circuit or electrical system overload. The red wire
must be connected to the positive 12 VDC power supply on the vessel. The black wire must be connected
to the negative or ground power supply of the vessel.
The white wire is an auxiliary or optional output from the receiver. In the event of an ‘alarm’ signal being
received by the receiver, an output is automatically transmitted through this white wire. This output signal
may be used to activate an ‘engine cut-out’, a flashing light, an external alarm klaxon or may even be
interfaced to an external MOB input on certain marine electronic GPS and navigation systems. If utilising
this auxiliary output signal, it MUST be connected to any peripheral equipment via an external relay. This
must be performed by a qualified marine or automotive electrician. Once the power cable has been
connected to the vessel power (vessel power should be switched on), the receiver is now ready for
operation.

c.
Omni-Directional Antenna
The omni-directional-antenna is a marine grade antenna which has the capability of receiving a Seasafe
Transmitter signal within 360 degrees, provided the Transmitter is within signal receiving range. The
higher this antenna is mounted on the vessel, the greater the receiving range of the system. Therefore
the omni-directional antenna should be mounted at the highest practical point on the vessel. The antenna
should be mounted using the antenna mounting bracket (supplied) and stainless steel fasteners (not
supplied). The coaxial antenna cable should be run from the antenna to the Receiver ensuring that the
cable is not exposed or in a position to be damaged in any way. The coaxial cable plug must be
connected to the receiver input connector marked “omni-directional antenna”.
d. Collapsible Directional-Antenna
The directional or Yagi antenna is a portable hand-held marine grade aluminium antenna. It should be
safely stowed in the vessel folded up where it is easily accessible in case of an emergency. In the event
that it is required to use this antenna, it should be removed from its plastic sleeve and the folded elements
should be folded out for use. The coaxial cable attached to the antenna must be connected to the input
marked “directional-antenna” on the receiver. The “directional-antenna” may be mounted on the vessel in
a semi-permanent position utilising the optional “mast-mount” adapter.
This aluminium adapter is bolted to the vessel in an appropriate position as high as possible and the
unfolded antenna simply ‘clicks’ into the adapter. It may be removed by simply ‘un-clicking’ it from the
adapter if and when required.

System Operation
Once the receiver and omni-directional antenna have been correctly installed, the Seasafe Receiver is
ready for operation. To switch the system on, depress the “on” key. Once the “on” key has been
depressed, the “alarm”, “on” and signal gain button “6” will be illuminated. If the receiver is connected to
the vessel power, the “BATT CHG ON” indicator will also be illuminated. This indicates that the internal
batteries are being charged. Each time the receiver is switched on, the device will default to these
settings. If the “BATT CHG ON” indicator fails to illuminate when connected to the vessel power, please
first check that power is being supplied to the receiver and also check the condition of the in-line fuse.
Provided there is power to the device and the fuse is operational, if the receiver “BATT CHG ON” still fails
to illuminate then return the receiver to your closest Seasafe dealer for inspection and possible battery
replacement.
If the receiver is removed from the vessel power source, the “BATT CHG ON” indicator will no longer be
illuminated. However, continued use of the receiver is possible as the receiver will be powered by the
internal batteries. The length of time the receiver is able to operate in this mode is dependent on whether
the internal batteries are fully charged. The receiver may continue to operate for up to 3 hours on a full
charge. It is not recommended to operate the receiver in portable mode for extended lengths of time. As
the internal battery power decreases, the range and accuracy capabilities of the receiver are reduced
substantially and normal operation becomes unreliable. The receiver should only be used in the portable
mode (disconnected from vessel power) in absolute emergencies only.
The receiver is now ready to receive any emergency signal transmitted by a Seasafe transmitter
(SSTX/01or SSTX/DV) which is within range.
If a Seasafe transmitter is activated within range of the receiver, the receiver’s in-built alarm siren will emit
a high pitched audible alarm tone. The volume level of this alarm is factory set and cannot be adjusted. At
the same time, a number of “signal strength indicator” lights will be illuminated. The more lights which are
illuminated on the “signal strength indication”, the stronger the signal being received. At this point the
operator or skipper should depress the “SEARCH” button. This button will become illuminated and the
“ALARM” button will no longer be illuminated. The omni-directional antenna must now be unplugged from
the receiver and the collapsible directional-antenna must be unfolded and plugged into the receiver socket
marked “directional antenna”. (The omni-directional antenna need only be unplugged if the receiver is to
be used portably. The receiver automatically switches between omni and directional antennae when the
receiver is switched from “Alarm’ to ‘Search’ mode). The receiver will begin to emit a warbling audible
tone. This is an audible signal strength indication. The volume level of this audible signal strength indicator
is adjustable either up or down via the volume “UP” or “DOWN” buttons. The directional antenna is held in
the hand in the vertical plane (see picture below) and the operator should very slowly rotate the antenna
through 360 degrees. If the directional antenna is permanently fixed to the vessel then the vessel should
be slowly manoeuvred through 360 degrees. The visual and audible signal strength indicators will vary as
the antenna is moved. The point within 360 degrees where the most signal indicator panel lights are
illuminated and where the audible tone is most highly pitched, will indicate the approximate direction from
which the transmitted signal is being received. If maximum signal strength is received through an arc (say
90 degrees) then the vessel should proceed directly towards the middle point of this arc. See diagram
below. The vessel must now move in this direction whilst the operator continues to scan with the
directional antenna. As the vessel gets closer to the transmitter signal source, the visual and audible
signal strengths will increase. In order to narrow the search angle or arc, the operator should now start to
systematically depress the “SIGNAL GAIN” switches down from number “6”. The signal strength
indications will reduce in intensity. Again, if the strongest signal is received through an arc then the boat
should proceed towards the centre position of this arc. If the vessel has an on-board compass, then a
compass bearing can be used to obtain the direction of the centre of this arc. The operator should
randomly continue to rotate the antenna through 360 degrees to check for any other transmitted signals as
there may be more than one activated transmitter at a time. By continuing to reduce the signal gain and to
follow the direction of the strongest received signal, the vessel should eventually come in visual contact
with the victim and they can be safely retrieved. If on ‘GAIN POSITION 1’ maximum signal strength is
being received through 360 degrees and the victim is not visual, the directional antenna may be
unplugged from its socket and plugged into the ‘Omni-Directional’ antenna socket. This will allow the
victim to be tracked even closer. Once a victim has been retrieved, their Seasafe transmitter should be
deactivated. Assuming there were no other victims in the water at the same time, the receiver audible and
9
visual signal strength indications should cease. If the receiver continues to receive a signal, the same
search procedure should be followed and any other victims located and retrieved.
Once all victims have been retrieved, the receiver should be switched “OFF” and then “ON” to return it to
its default stand-by mode. If the system has been used in the portable mode, the directional-antenna must
be unplugged from the receiver, folded up and stowed safely for future use and the Omni-directional
antenna must now be immediately plugged into the receiver to scan for any future alarms.

The Seasafe receiver may receive transmitter signals up to the following ranges:
♦
♦
♦
Up to 10 km – 15 km from water to vessel
Up to 20 km from water to base station with 15m high antenna mast
Up to 100 km from water to aircraft at 1500 m altitude
These ranges are not guaranteed and signal transmission ranges may be affected by a number of factors
including but not limited to, prevailing weather conditions, sea state, wave height, cloud cover and line of
sight obstructions.

Accessories
a.
Directional Antenna Mast-Mount Adapter (Optional)
The directional mast-mount adapter is a marine grade aluminium bracket which allows the directional
antenna to be mounted permanently or semi-permanently in a position on a vessel.
This is particularly useful for instances when there may only be two people aboard a vessel. If one of the
crew fall over-board, the remaining person will need to operate the vessel and conduct the search at the
same time. He would not be able to steer the vessel and operate the antenna in the hand-held position. By
clipping the antenna into the adapter (which would be mounted in an appropriate position on the vessel)
the remaining crew member would be able to steer the vessel according to the signal strength indicated
on the receiver. This would be opposed to typically holding the antenna in-hand and turning to face a
particular direction. This has proven to be an effective method of tracking a signal.

c.
Audio Headset (Standard)
The Seasafe receiver is supplied complete with a lightweight audio headset. Under conditions of extreme
ambient noise or in cases where the skipper is unable to watch the ‘visual’ signal strength meter, the
headset can be plugged into the device and used to track the received audio signal.
The volume level of the audible signal strength indicator is adjustable up or down via the volume “UP” or
“DOWN” buttons.
