FOREWORD
A Word to the Owner of the FS-1575/2575/5075
Congratulations on your choice of the FURUNO FS-1575/2575/5075 SSB Radiotelephone. We
are confident you will see why the FURUNO name has become synonymous with quality and reliability.
Since 1948, FURUNO Electric Company has enjoyed an enviable reputation for innovative and
dependable marine electronics equipment. This dedication to excellence is furthered by our extensive global network of agents and dealers.
Your equipment is designed and constructed to meet the rigorous demands of the marine environment. However, no machine can perform its intended function unless properly installed and
maintained. Please carefully read and follow the operation and maintenance procedures set forth
in this manual.
We would appreciate feedback from you, the end-user, about whether we are achieving our purposes.
Thank you for considering and purchasing FURUNO equipment.
Features
The FS-1575/2575/5075 is an MF/HF SSB Radiotelephone with a built-in DSC/Watch Receiver,
all contained in a surprisingly compact cabinet. An NBDP (Narrow Band Direct Printing) Terminal
Unit is optionally available.
Data is displayed on a large, easy-to-read color LCD. Operation is simplified by the use of few
keys and easy-to-follow menus.
The built-in DSC/Watch Receiver produces and receives digital selective callings for quick and efficient establishment of distress, urgency, safety and routine communications with other ships and
coast stations that install any MF/HF DSC facilities.
Keep pressed for 4 sec in case
of DISTRESS. The alert is
transmitted with steady lighting.

3) Push the ENTER knob to close the setting window.
Note: When TX and RX frequencies are different, first enter TX then enter RX.
2.3Transmission
After selecting the class of emission and frequency, you can transmit by pressing the
PTT switch on the handset.
2.3.1Transmission procedure
Maximum transmission power is achieved only when the antenna impedance and
transmitter impedance match each other. Because the antenna impedance changes
with frequency, antenna impedance matching with the transmitter impedance is done
with the antenna coupler. The antenna coupler automatically tunes the transmitter to
a wide range of different antenna lengths. The available range is;
• Wire antenna 10 to 18 meters long (horizontal part)
• Whip antenna eight meters long (Horizontal feeder is two meters or longer.)
• Whip antenna 10 meters long
To initiate the tuning, do the following:
1.Press the PTT switch on the handset. Tuning is automatically adjusted at first
transmission after frequency is changed. For manual tuning, press the 0/TUNE
key on the RT screen. If tuning fails, the message "TUNE NG" appears and the
output power is automatically set to [LOW] (for FS-1575/2575) or [LOW2] (for FS-
5075).
2. SSB RADIOTELEPHONE
2.Hold the handset close to your mouth, press the PTT switch and speak clearly.
Note: When tuning is initiated in the two control unit system, the screen of the idle control unit shows "OCCUPIED (CONTROLLER 1 (or 2))". In this case, only the
DISTRESS key is operative on the idle control unit.
2.3.2How to change transmission power
To minimize possible interference to other stations, reduce the transmission power.
This should be done when using the transceiver in a harbor, near the shore or close
to communication partner (other ship).
1.Rotate the ENTER knob to select [HIGH], [MID], [LOW] (for FS-1575/2575),
[LOW1] (for FS-5075) or [LOW2] (for FS-5075) (whichever is displayed), then
push the knob.

Note: The temperature of the power amplifier is monitored. When its temperature rises above a certain temperature, output power is automatically reduced.
2.3.3Condition of the transmitter
While transmitting, you can display [IA] (antenna current), [IC] (collector current), [VC]
(collector voltage), [RF] (RF output) or [VS] (source voltage) on the RT screen.
1.Rotate the ENTER knob to select [IA], [IC], [VC], [RF] or [VS] (whichever is displayed) then push the knob.
2.Rotate the ENTER knob to select the option desired then push the knob.
Check the transmission power
During transmission, the IA bar deflects according to the current being fed from the
antenna coupler to the antenna feeder. The unit of readout is amperes. The antenna
current varies with the effective antenna impedance. The reading differs by the frequency and antenna length. The output power is proportional to the square of an antenna current.
