2.3 Transmission
After selecting the class of emission and frequency, you can transmit by pressing the
PTT switch on the handset.
2.3.1 Transmission 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. 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 con-
trol unit shows "OCCUPIED (CONTROLLER 1 (or 2))". In this case, only the
DISTRESS key is operative on the idle control unit.
2.3.2 How 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.

2. Rotate the ENTER knob to select the option desired then push the knob.
Note: The temperature of the power amplifier is monitored. When its temperature ris-
es above a certain temperature, output power is automatically reduced.
2.3.3 Condition 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 dis-
played) 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 fre-
quency and antenna length. The output power is proportional to the square of an an-
tenna current.

3. DSC OVERVIEW
3.1 What is DSC?
DSC is an acronym meaning Digital Selective Calling. It is a digital distress and gen-
eral calling system in the MF and HF bands used by ships for transmitting distress
alerts and general calls and by coast stations for transmitting the associated acknowl-
edgements.
For DSC distress, safety and urgency callings in the MF and HF bands, the frequen-
cies are 2187.5, 4207.5, 6312.0, 8414.5, 12577.0, and 16804.5 kHz.
3.2 DSC Message
DSC calls are roughly divided in two groups: distress messages and general (safety,
urgency and routine) messages. Below are the types of DSC messages.
*SPECIAL MSG: To send these messages, set [SPECIAL MSG] to [ABLE]. See
section 6.18.

3. Communicate with the coast station.
4.1 How to Send Distress Alert
GMDSS ships carry a DSC terminal with which to transmit the distress alert in the
event of a life-endangering situation. A coast station receives the distress alert and
sends the distress alert acknowledge call to the ship in distress. Then, voice or telex
communication between the ship in distress and coast station begins. Transmission
of the distress alert and receiving of the distress alert acknowledgement are complete-
ly automatic - simply press the DISTRESS key to initiate the sequence.
There are three types of distress alerts; MULTI, SINGLE, AUTO. MULTI is used nor-
mally. To use another method, see step 10 in paragraph 4.1.2.
Note: After sending the distress alert, no control unit has priority.
4.1.1 How to send distress alert by DISTRESS key with distress in-
formation not edited
1. Open the DISTRESS key cover then press the DISTRESS key for four seconds.

ceive the distress acknowledge call from a coast station. The elapsed time since
transmission is displayed. At this time, the icons for other DSC received messag-
es except the distress alert acknowledge call are not displayed. You can only con-
firm them in the log.
Note: If you do not receive the distress alert acknowledge call, the equipment au-
tomatically re-transmits the distress alert after 3 min 30 seconds to 4 min 30 sec-
onds. Then awaits the distress alert acknowledge call. This is repeated until the
distress alert is acknowledged.
You can temporarily stop the countdown for next retransmission by selecting
[PAUSE] in the user options area. [PAUSE] indication changes to [START] and
[PAUSE] is displayed instead of the countdown indication. To restart, select
