INTRODUCTION
The SAILOR RT2048 VHF radiotelephone has been designed
to comply with the increasing demands of a highly technological
product, which means high quality, small size, etc.
The SAILOR RT2048 has furthermore been designed to fit into
the SAILOR Compact 2000 module programme.
The SAILOR RT2048 can either be installed and operated as
an independent unit, or in combination with other elements of
the Compact 2000 programme. These include a duplex VHF
radiotelephone, a coast telephony station with a 400W PEP
SSB transmitter, and an SSB receiver with built-in FM and AM
bands, and a scrambler which ensures complete communica-
tion secrecy.
The SAILOR VHF RT2048 has, by means of the latest technol-
ogy in casting technique, been constructed to withstand the most
extreme conditions experienced in small, semi-open boats. Its
compact, weatherproof construction ensures a degree of resist-
ance to sea spray.
The printed circuits inside have been designed with a high degree
of compactness and exceptional performance.
For more than half a century, SAILOR has been synonymous with
state-of-the-art, high-quality maritime communications equipment
- known for sturdiness, ease of operation and compact design.
SAILOR is a world leader in the technologically advanced field
of maritime communications. A wide range of products from
GMDSS equipment, UAIS, and satellite communications equip-
ment to simple VHF radios ensures the safety at sea and the
daily communication around the world.
In the design of this VHF RT2048 radiotelephone, SAILOR has
taken into account all the circumstances it will be exposed to
in day-to-day operation. However, even a product of this high
quality requires regular servicing and maintenance, and we
recommend a close observance of the directions contained in
the instruction manual.
Fast and professional service is one of our main concerns.
SAILOR has a world-wide net of authorized distributors in more
than 90 countries - and on top of that the SAILOR Certified
Service Centre concept. In this way we are able to service you
in the best way possible all over the world.

This is:
NAME OF SHIP, call sign or
other identification (THREE
TIMES), followed by:
MAYDAY - NAME OF SHIP -
Position, type of emergency,

mation which may help rescue
operations.
For clarity when SPELLING OUT
words, the following alphabet

16, the call should be repeated
on any other available channel.
3. Speak slowly, pronouncing
each word distinctly.

OPERATING
The operating panel is provided
with a really high quality pushbut-
ton keyboard, offering an attrac-
tive solid feel. Furthermore, keyed
operations are instantly confirmed
by means of the display read-out.
To ensure safe operation under all
conditions, the keyboard is fitted
with night-time illumination.
SIMPLEX/SEMI-DUPLEX
COMMUNICATION
All the communication, that means
ship/ship, ship/port, and ship/coast
station, is carried out in the sim-
plex or semi-duplex mode. This
means that the handset key switch
is depressed while the message
is delivered, ending with the word
"over". The switch is now released,
allowing the other party to reply.
PRIVATE CHANNELS
There is standard provision for the
programming of up to 10 private
channels. However, it is possible
to increase the total to 40 private
channels if the scanning facilities
are not required.
A private channel is indicated with
a prefix and a single digit. For the
10 standard channels the prefix is
a “P”, if increased to 40 private
channels the prefix will be “A”, “E”
and “F”.
Private channels include fishing
and leisure channels as well as the
special channels allocated by post
and telegraph authorities.

US-CHANNELS
In the USA a number of the inter-
national duplex channels are used
as simplex channels. Ships sailing
in American waters must, therefore,
be able to select these channels
as simplex channels. The appear-
ance of "US" on the display indi-
cates that this mode of operation is
in use.

CHANNEL READ-OUT
All international maritime channels
are shown by the two digits, when

REDUCED POWER
In harbour areas, or in the close
vicinity of another vessel, transmis-
sions should be with reduced pow-
er. When the display shows 1W,
the transmitter power output is
reduced from 25W to 1W.
Where two stations are close
together, this reduction can
improve communication quality.
•TRANSMITTING
Whenever the handset switch is
depressed, and the transmitter
output power level has reached
an appropriate level, the "TX" will
appear.
If the transmitter time-out timer
is enabled, and an automatic ter-
mination of a transmission has
occurred, this indicator will be
flashing.
•

OPERATION
The VHF radiotelephone is operated by means of two turn-style knobs
and a push-button keyboard. This combination ensures a high continuous
resolution on squelch and AF-level, and an easy selection of channels etc
in all situations.
The highly efficient LED-display shows the operating channel both under
normal use and in dual watch mode. The display also indicates when the
set is scanning or a call has been detected by the selcall decoder. The
functions 1W, TX, and US are indicated by means of LED-illumination.
When the station is switched off, the necessary settings will be stored in
the built-in-memory, and as soon as the station is switched on again, it will
start up on the same channel etc.

DUAL WATCH OPERATION
SELECTIVE CALLING
(If built-in)
When a selective call is received from a coast station, the read-out
will alternatively show CA, and the actual selected channel and the
acoustic alarm will sound for 10 seconds.
When an "all ships call" containing distress messages, gale warnings,
navigational warnings, etc, is received from a coast station, the read-
out will alternatively show C0, and the actual selected channel and
the acoustic alarm will sound until the selcall is reset.
In addition to the selected channel, which is shown on the display, the VHF
station will listen on channel 16 for 0.1 second every 1.2 second.
If there is a signal on channel 11, the dual watch sequence will be as follows:
Any signal received on channel 16 will be heard continuously and the read-
out will show "16" until the signal ceases.
If the transmitter is keyed, the dual watch function will be switched off and the
read-out will show the channel selected.

SCANNING OPERATION
(If scanning is enabled)
The VHF radiotelephone is provided with a flexible scanning facility.
The scanning programme is fully user programmable, and can include all the
international channels and the ten private channels PO -P 9.
When a scanning programme is created by the operator, the programme will
be stored in a memory which retains the scanning programme even when
the station is switched off.
The scanning programme can be changed during operation by pressing
"ADD" or "DELETE".
SCANNING
In principle, scanning is an advanced form of the dual watch system in which
the secondary channel selected changes constantly whilst the distress and
call channel 16 is listened to simultaneously
If, for example, a scanning programme consists of channels 6, 11, 17, and 70,
the scanning sequence will look like this:
If there is a signal on channel 11, the sequence will be:
The "Scan Time" is the time during which the scanner listens on channel
11 whilst at the same time watching out on channel 16 - exactly as it
happens on the dual watch system. The "Scan Time" can be programmed
by the operator
To obtain a continuous listening to the signal being received on channel 11,
the scanning is stopped by simply pressing "SHIFT" "SCAN".
The scanning can be started again by pressing "SHIFT" "SCAN".
