Preface
Radio for occupational use
The SAILOR 6000B MF/HF DSC fulfi ls the requirements of the SOLAS directive and is intended for use in maritime
environment.
SAILOR 6000B MF/HF DSC is designed for occupational use only and must be operated by licensed personnel only.
SAILOR 6000B MF/HF DSC is not intended for use in an uncontrolled environment by general public.
Training information
The SAILOR 6000B MF/HF DSC is designed for occupational use only and is also classifi ed as such. It must be ope-
rated by licensed personnel only. It must only be used in the course of employment by individuals aware of both
the hazards as well as the way to minimize those hazards.
The radio is thus NOT intended for use in an uncontrolled environment by general public. The SAILOR 6000 MF/HF
DSC has been tested and complies with the FCC RF exposure limits for Occupational Use Only. The radio also complies with the following guidelines and standards regarding RF energy and electromagnetic energy levels including
the recommended levels for human exposure:
• FCC OET Bulletin 65 Supplement C, evaluating compliance with FCC guidelines for human exposure to radio
frequency electromagnetic fi elds.
• American National Standards Institute (C95.1) IEEE standard for safety levels with respect to human exposure
to radio frequency electromagnetic fi elds, 3 kHz to 300 GHz
• American National Standards Institute (C95.3) IEEE recommended practice for the measurement of potentially
hazardous electromagnetic fi elds - RF and microwaves.
Below the RF exposure hazards and instructions in safe operation of the radio within the FCC RF exposure limits
established for it are described.

Warning
The SAILOR radio set generates electromagnetic RF (radio frequency) energy when transmitting. To ensure that no
personnel will be exposed to excessive amounts of RF-energy and to avoid health hazards from excessive exposure
to RF energy, the following safety distances must be followed:
Antenna Safety distance
150W Calculated: 1.71 m or 5.7 feet
250W Calculated: 2.21 m or 7.3 feet
500W Calculated: 3.12 m or 10.3 feet
Calculations cover a whip antenna with a maximum gain of 3dBi, worst case frequency (30 MHz), full power and
100% duty cycle (transmitter always on) considering the most conservative limits mentioned in:
FCC OET Bulletin 65 (1997)
Canada RSS102 (2010)
Canada Safety Code 6 (2015)
Installation Example for 150W
1. A whip antenna with a maximum gain of 3 dBi must be mounted at least 12.3 ft. (3.71m) above the highest
deck where people may be staying during continuous radio transmissions. The distance is to be measured
vertically from the lowest point of the antenna. This provides the minimum separation distance which is in
compliance with RF exposure requirements and is based on the MPE radius of 5.7 feet (1.71 m) plus the 6.6 ft.
(2.0 m) height of an adult.
2. On vessels that cannot fulfi ll requirements in item 1, the antenna must be mounted so that the lowest point of
the antenna is at least 5.7 feet (1.71m) vertically above the heads of people on deck and all persons must be
outside the 5.7 feet MPE radius during radio transmission.
• Always mount the antenna at least 5.7 feet from possible human accessNever touch the antenna when
transmitting.
• Never touch the antenna when transmitting.
• Use only authorized T&T accessories.
• Only allow trained and certifi ed operators knowing about RF-energy and hazards to operate the radio.
3. If the antenna has to be placed in public areas or near people with no awareness of the radio transmission, the
antenna must be placed at an even greater distance. Consult the appropriate standard for exact limits, depending
on national specifi cations.
Failure to observe any of these warnings may cause RF exposure exceeding above mentioned limits or create dangerous conditions..

General information
1.1 Introduction
The 150 W/250 W/500 W MF/HF transceiver with integrated DSC and telex (NBDP) is designed for maritime applications in voluntary as well as compulsorily fi tted vessels. It offers simplex and semi-duplex
SSB radiotelephone communication in the maritime mobile frequency bands between 1.6 and 30 MHz.
The basic version of the transceiver includes voice, DSC and a dedicated 2187.5 KHz DSC watch receiver,
forming an ideal system for MF GMDSS installations.
The equipment consists of a compact transceiver control unit, a fully remote controlled transceiver unit
and an automatic antenna tuning unit.
The microprocessor controlled Antenna Tuning Unit automatically matches the impedance of antennas
between 8 and 18 metres in length and requires no presetting at the installation. It is designed for outdoor
installation and may be located up to 100 metres from the Transceiver Unit.
The Transceiver Unit contains all receiver and transmitter circuits. The fully protected solid state 150 W/
250 W /500 W power amplifi er matches a 50 ohm antenna system, but is normally used in connection
with the Antenna Tuning Unit. The DSC/Telex modem contains two demodulators, one connected to the
built-in watch receiver for continuous watch on the DSC distress frequencies, the other connected to
the communication receiver which may be used to keep simultaneous watch on other DSC frequencies
or telex communication.
The transceiver can be upgraded to scan 6 DSC channels, and Telex operation to comply with MF/HF
requirements in sea area A4. Codes are purchased as accessories for the system.
The Control Unit is for operation of radiotelephony as well as DSC and confi guration. Use of the equip-
ment is simple, logic and straight forward. DSC operation is based on the use of soft keys. Guiding texts
are provided and the large display is able to show the contents of a complete call in one screen.
For telex operation the Message Terminal must be connected to the system via the CAN bus.
The equipment is designed for operation from a 24 V DC supply, like e.g. a battery. With the optional AC
Power Supply unit installed the equipment may be supplied from 115/230 V AC main or emergency supplies with automatic switch-over to 24 V DC supply in the absence of AC supply voltage. Also optionally, a
battery charger for AC is available in the product line.
The built-in test facilities and easy-to-replace module design of the equipment simplifi es the service concept.

Dissipated heat: The dissipated heat in standby RX mode is typically 45 W depending on
attached ancillary equipment.
In transmit mode, use the consumption fi gures for the appropriate mode,
multiplied by 0.66.
E.g. 0.66 x 175 W = 115.5 W dissipated heat for a 150 W system in SSB
speech mode.
For a fi gure in kilocalories (kcal), multiply dissipation effect by on-time in
hours and then by 0.860.
For the 150W system, e.g. 115.5 W x 2 h + 45 W x 22 h (TX 2 hours + RX
22 hours a day) = 1221 Wh. 1221 Wh x 0.860 ~ 1050 kcal a day.
