Operation Manual
S15
1. Introduction
The S15 is a Class-D Digital Selective Calling (DSC) VHF marine transceiver
with built in GPS capability (position, waypoints, course and speed over the
ground) if connected with GPS input from either a GPS navigator or smart
antenna. The S15 also has full NAVTEX message display capability when
interfaced with a suitable NAVTEX antenna/receiver unit. The transceiver is a
25-watt, frequency modulated waterproof transmitter/receiver for applications
in the 156.025 - 162.550MHz band.
The S15 supports the latest GMDSS requirement for non-SOLAS vessels
from the international maritime organization (IMO).
The S15 will enable you to make digitally selected calls, which are quicker
and simpler to make then conventional voice calls using channel 16. Should
a distress urgency or safety situation occur, with the S15 you can quickly
raise an alert, indicating your identity, your position and automatically
establish distress communication on the emergency voice channel.
The S15 will display received NAVTEX messages and the ID of received
messages from the NAVTEX receiver. NAVTEX is a worldwide coastal telex
broadcast system. The broadcast stations transmit navigational warning,
meteorological warnings, Search And Rescue (SAR) information and other
data for ships sailing within their service range.
If the S15 is connected with a GPS, it will also display your vessels position
and Universal Time Coordinated (UTC) and it can also give you the COG
(Course Over Ground), SOG (Speed Over Ground), BTW (Bearing To
Waypoint) and DTW (Distance To Waypoint) of your vessel.
Silva operates a policy of continual development and reserves the right to
alter and improve the specification of their products without notice.

The “waypoint number” represents the number of waypoints. You can
find the “waypoint number” under the directory of “Waypoint Overview”.
For example, if the waypoint number shows “05”, it means that there are
5 waypoints stored. Please note that the maximum storage for waypoints
is 50. If the storage exceeds the maximum storage, the display will
indicate “Invalid Data” to express that the input is invalid. The screen
setting will go back to SET WAYPOINT NUMBER automatically after 1
second approximately for data to be input again.

14. Installation
14.1 Unit Installation
The S15 should be sited so that engine noise and vibration or other
background noise does not make it difficult for the operator to hear.
It is recommended that it is not installed where it will be exposed to
continuous direct sunlight as this will eventually damage the LCD display.
As loudspeakers contain powerful magnets, the radio should not be
installed within 1m (3ft 3in) of any compasses, whether magnetic or
electronic.
The fins on the back of the case act as a heat sink to dissipate heat
generated by the set when in use, which maintains the high efficiency of
the radio. The free circulation of air is essential - if mounting the radio is
in an enclosed space ensure that the space is vented.
The S15 is supplied with a reversible mounting bracket. This can be used
to mount the radio on the chart table or on an overhead bulkhead (Fig A).
Before installing, ensure that there is at least 101mm (4.0 in) verticals
clearance and 70mm (2 3/4in) horizontal clearance behind the bracket to
allow the radio to fit (Fig B). The rake angle of the radio can be adjusted
by slackening the clamp.
Fig A
Fig C
Fig B
Page 45
Operation Manual
S15
On the back of the case of S15 there is a antenna socket, a power cable
socket and a jack socket for an external speaker / the GPS input and
NAVTEX input (Fig D).
Fig D
The S15 requires a 12v DC supply to operate, this lead should be connected
to the vessel’s power supply (the red wire is positive, black is negative),
keeping the cable runs as short as possible. Although the radio draws very
little current when receiving, a heavier current is drawn when transmitting
which may result in a voltage drop if very long cable runs are used of
inadequate core diameter. If the supplied power lead is not long enough, an
extension of up to 3m(10 ft) can be made using at least 2.5mm (13AWG)
wire.
The chassis of the S15 is not connected to either supply rail. This allows a
direct connection to the ship’s earth connection for voltage and RF interface
protection. The red wire is positive and black is negative. If polarity is
accidentally reversed, the set will not operate.
The antenna is connected to the S15 using a standard PL259 type connector
as fitted to most marine antennae. If fitting to an existing antenna, check that
the contacts are not corroded before connecting, as this will affect the quality
of the signal, Ensure that the retaining collar of the antenna plug is securely
tightened to prevent accidental disconnection.
14.2 Antenna Installation Recommendations
The most important factor in the performance of the S15 will be the quality
and positioning of the antenna. Most recorded problems with VHF radios are
related to poor antenna siting, faulty cabling, poor quality cable joints and low
voltage supply. Even the best performing radio cannot compensate for these
factors. If replacing an existing installation using the same antenna, it is
important that these factors are checked when installing the radio.
Page 46
Operation Manual
S15
As the range of VHF signals are governed by line of sight, the antenna
should be placed as high as possible, while remaining clear of any
metallic objects that could influence the resonance of the antenna.
The most popular antennae for marine use are 1m (3ft 3in) long. On sail
boats these are usually mounted at the masthead, where the length of
the antenna keeps it clear from the navigation lights and wind vanes etc.
This type of antenna can also be mounted on the cabin roof or radar arch
on powerboats.
Longer whip antennae are recommended for larger boats. These radiate
the same total power as smaller antennae, but concentrate it into a
narrower beam, which is advantageous on a tall mast at extreme range
where concentrating the available power into a narrow horizontal beam
becomes more important. However, if the antenna is not vertical when
transmitting, the beam will be angled either too high or too low (Fig E).
Here the wider beam of the shorter antenna will be more universally
effective, although the signal will be weaker (Fig F):
Fig E
Fig F
Therefore vessels with a large heel angle (small sailboats) would be
better choosing a short masthead antenna. Your local agent should be
able to provide specific advice on antenna choice for the vessel it is to be
fitted to.
The antenna coaxial cable and any connectors used must be rated at 50
Ω . Under no circumstances should standard domestic TV cable and
connectors be used. Incorrectly rated cabling and connectors could result
in power not reaching the antenna, but also power could be reflected
back into the radio, damaging it in the process.
