3. The audio alarm sounds; press the [CANCEL] key to silence the alarm.
4. Communicate with the coast station via radiotelephone or NBDP Terminal Unit as
below. (In the dual control unit system, communication can be done from any control
unit, after the distress alert has been transmitted. To restore priority to the #1 control
unit after completion of distress communications, turn the power off and on again.)
Radiotelephone
a) Say MAYDAY three times.
b) Say “This is …” name of your vessel and your call sign three times.
c) Give nature of distress and assistance needed.
d) Give description of your vessel (type, number of persons onboard, etc.) and any other
information which may aid in rescue.
NBDP Termi nal Unit
a) Press the function key [F3] on the keyboard of the NBDP Terminal Unit to show the
Operate menu.
b) Call Station is selected; press the [Enter] key.
c) DSC is selected; press the [Enter] key.

WARNING
ELECTRICAL SHOCK HAZARD
Do not open the equipment.
Only qualified personnel
should work inside the
equipment.
Immediately turn off the power at the
switchboard if water leaks into the
equipment or something is dropped in
the equipment.
Continued use of the equipment can cause
fire or electrical shock. Contact a FURUNO
agent for service.
Do not disassemble or modify the
equipment.
Fire, electrical shock or serious injury can
result.
Immediately turn off the power at the
switchboard if the equipment is emitting
smoke or fire.
Continued use of the equipment can cause
fire or electrical shock. Contact a FURUNO
agent for service.
Do not operate the equipment with wet
hands.
Electrical shock can result.
CAUTION
Use the proper fuse.
Use of the wrong fuse can cause serious
damage to the equipment and void the
warranty.
ii
CAUTION
Do not operate the [DISTRESS] button
except in case of a life-endangering
situation on your vessel.
If the distress alert is accidentally
transmitted, contact the nearest coast
station and inform them of the accidental
transmission as follows:
a) Ship's name
b) Ship's call sign and DSC number
c) Position at time of transmission
d) Time of transmission
WARNING LABEL
A warning label is attached to the
transceiver unit and a danger label is
attached to the antenna coupler.
Do not remove the labels.
If a label is missing or illegible,
contact a FURUNO agent or dealer
about replacement.
WARNING
To avoid electrical shock, do not
remove cover. No user-serviceable
parts inside.

Features
The FS-1570/FS-2570 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 backlit 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 calls 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.

1.10 Power Supply Unit (option)
The control unit works directly on 24 VDC or through a Power Supply Unit on AC mains
supply (115 or 230 VAC). The power supply unit is type PR-300, supplying 24 VDC power
(20 A) to the FS-1570 or type PR-850A, supplying 24 VDC (40 A) to the FS-2570. Both
115/230 VAC and 24 VDC power can be connected simultaneously. In this case, the
system normally operates on the AC mains supply and when AC power is lost, the PSU
automatically switches to the DC power source.
This power supply arrangement satisfies the GMDSS requirements. The
FS-1570/FS-2570 can be operated directly from 24 VDC without a rectifier unit.
OVEN power supp ly: The crystal oven is always powered even when the Power Switch
is OFF. It draws 50 mA approx. The Oven LED lights while the oven is powered.
AC and DC power switches
Both AC and DC power switches on the PSU can be always kept on. (These switches are
provided to turn off the power supply for maintenance.) The control unit may be turned on
or off with the PSU kept on.

b) Rotate the [ENTER] knob to set digit.
c) Push the [ENTER] knob.
Note: To enter same frequency for both TX and RX, enter the TX frequency first.
2.1.3 Tuning
Maximum transmission power is achieved only when the antenna impedance and
transmitter impedance match each other. Because the antenna impedance changes with
frequency, a means must be provided to match (tune) the antenna impedance with the
transmitter impedance. This is done with the antenna coupler. The antenna coupler
automatically tunes the transmitter to a wide range of different antenna lengths, from 7 to
30 m.
To initiate the automatic tuning, do the following:
1. Press the PTT switch on the handset or the [LOG/TUNE] key on the control unit.
“TUNING” appears when the [LOG/TUNE] key is pressed; “TX” pops out when the PTT
switch is pressed.
Tuning will be completed within 2 to 5 seconds for a newly selected frequency, or less
than 0.5 seconds for a once-tuned frequency. (A memory saves coil and capacitor
settings.) When the tuning process is successfully completed, TUNING: OK appears. If
tuning fails, TUNING: NG appears.

Note: When tuning is initiated in the two-control unit system, the display of the idle control
unit shows “OCCUPIED(ANOTHER CONTROLLER).” In this case, only the
DISTRESS button is operative on the idle control unit. Further, if a control unit is in
use when tuning is attempted at the other control unit, the display of the control unit
which attempted to tune shows “OCCUPIED” plus the name of the equipment in
use: ANOTHER CONTROLLER, NBDP, or DMC.
2.1.4 Using the handset
Hold the handset close to your mouth, press the PTT switch and speak clearly.
2.1.5 Monitoring transceiver output power
During transmission, the IA bar deflects according to the current being fed to the antenna
feeder from the antenna coupler. The unit of readout is amperes. The antenna current
varies with the effective antenna impedance. The swing differs by the frequency and
antenna length. The output power is proportional to the square of an antenna current.
Note: If IA is not shown, follow the procedure in paragraph 2.1.7 to show it.

2.1.6 Reducing transmitter power
To conserve energy and 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 choose LOW, MID or HIGH (whichever is shown) at the
top of the screen and then push the [ENTER] knob.

2. Rotate the [ENTER] knob to choose power among LOW, MID and HIGH as
appropriate and then push the [ENTER] knob.
Note: Power amplifier temperature is monitored, and when its temperature rises above a
certain temperature output power is automatically reduced.
2.1.7 Displaying IA, IC, VC or RF
While transmitting, you may display RF (PA output), IA (antenna current), IC (collector
current) or VC (collector voltage), at the lower right corner of the radiotelephone screen.
1. Rotate the [ENTER] knob to choose RF, IA, IC or VC, whichever is displayed at the
bottom right corner.
2. Push the [ENTER] knob.

2.2.1 RF gain (sensitivity) adjustment
In normal use the sensitivity should be set for maximum. If the audio on the received
channel is unclear or interfered with other signals, adjust (usually reduce) sensitivity to
improve clarity.
1. Rotate the [ENTER] knob to choose SEN at the bottom of the screen and then push
the [ENTER] knob.

The S-meter shows relative signal strength coming into the receiver frontend. Note that
the S-meter does not function when the AGC is turned off.

2.2.3 Monitoring traffic on intended transmit frequency
When a semi-duplex channel is selected, it is recommended to monitor if there is no
existing traffic on the frequency you are going to use. To do this, choose RX and then
push the [ENTER] knob. The transceiver monitors traffic on the selected frequency for
three seconds.
2.2.4 Receiving AM broadcasting stations
1. Press the [1/ RT/2182] key to show the radiotelephone screen.
2. Rotate the [ENTER] knob to choose MODE and then push the [ENTER] knob.
