1 OPERATIONAL OVERVIEW
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 power supply.
OVEN power supply: The crystal oven is always powered even when the Power Switch
is OFF, provided the mains switchboard is turned on.
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.

Choosing frequency
1. Rotate the [ENTER] knob to choose TX or RX as appropriate and then push the
[ENTER] knob.

2. Enter frequency by one of the methods below.
Entering frequency with the numeric keys:
Use the numeric keys to enter frequency and then push the [ENTER] knob. Be sure to
including trailing zero. For example, to enter 2161 kHz, key in [2], [1], [6], [1], [0].
(Keying in 2-1-6-1 will set 216.1 kHz.)
Choosing frequency with the ENTER knob (for RX only):
a) Use the [FILE/CURSOR] key to choose digit to change.
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 s for a newly selected frequency, or less than 0.5
s for a once-tuned frequency. (A memory saves coil and capacitor settings.) When the
tuning process is successfully completed, TUNE: OK appears. If tuning fails, TUNE:
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.
