1. VHF RADIOTELEPHONE  
OPERATIONAL OVERVIEW  
The FM-8700 system consists of a transceiver unit, a duplexer unit  
and two antennas. The transceiver unit contains a VHF transmit-  
ter, receiver, and channel 70 watch receiver module. All opera-  
tions are controlled on its front panel.

1.4 Selecting Channel Modes, Channels  
Selecting channel modes  
While pressing the CHANNEL selector, press the CH16 key to  
select the channel mode: International, USA (in the case of USA  
channel permitted), private (if authorized), or weather mode (USA  
channel permitted). The International version of the FM-8700 has  
no such selection.  
On the weather channel mode, a beep is emitted when the weather  
alert tone is received.  
Note: Private channels are available only where permitted by the  
authorities.  
Selecting channels  
Rotate the CHANNEL selector clockwise (counterclockwise) to  
display desired channel in the channel No. display window.  
1.5 Adjusting Volume of Loudspeaker  
The VOLUME control adjusts the volume of the loudspeaker.  
1.6 Adjusting Squelch, Selecting Operating Functions  
Adjusting squelch  
The SQUELCH control adjusts the squelch threshold level. Adjust  
it so that white noise heard in the loudspeaker just fades out. Per-  
form this operation when no traffic is being received.AUTO squelch  
automatically reduces white noise. Usually select the AUTO posi-  
tion. Avoid turning the squelch too far clockwise – you may miss a  
long distance communication.  
Note: To obtain correct scan watch/dual watch response, adjust  
the SQUELCH control precisely.  
Selecting operating function  
Every pressing of the SQUELCH control changes the operating  
function as follows:  
OFF

1.7 Transmitting  
Press the PTT (Press-to-talk) switch on the handset or microphone  
to talk, and release it to listen for the response. The VHF section  
keyboard accepts no key input when the PTT switch is operated.  
Remarks on transmitting  
• Before transmitting, think about the subjects which have to be  
communicated and, if necessary, prepare written notes to avoid  
unnecessary interruptions and ensure that no valuable time is  
wasted on a busy channel.  
• Listen before commencing to transmit to make certain that the  
channel is not already in use.  
1.8 Selecting Output Power  
Each press of the [HI/LOW] key selects HI or LOW output power.  
LOW appears when low power is selected. The transmitter power  
is automatically set for low on the following channels:  
International: CH15, CH17  
USA:  
CH13, CH15, CH17, CH67; to operate USA chan-  
nel 13 or 67 in high power, keep [HI/LOW] pressed  
while talking into the handset.  
1.9 Turning the Loudspeaker On/Off  
To turn the loudspeaker on/off, press the VOLUME control. The  
loudspeaker off mark appears when the speaker is off. The loud-  
speaker is automatically turned off when the telephone handset is  
used on semi-duplex channels.  
1.10 Automatic Selection of CH16  
Press the [CH16] key to select CH16, the International Calling and  
Safety Channel. The use is limited to distress, safety and calling.  
The transmission on CH16 (156.800 MHz) should be limited to  
within 1 minute except for distress calling.  
Avoid calling on CH16 for purposes other than distress, urgency  
and very brief safety communications when another calling chan-  
nel is available.

1.11 Dual Watch  
The dual watch function permits watch on CH16 and another se-  
lected channel. CH16 and another channel are watched at intervals  
of 0.15 seconds and one second, respectively.  
To start DW, first select the other frequency to watch and then  
press the SQUELCH control. When the receiver finds a signal on  
CH16, it locks on it and restarts dual watching after the signal on  
CH16 has gone. If another channel has traffic, it still continues  
dual watch. The speech is heard intermittently. If you are annoyed  
with the intermittence, turn off DW by pressing the PTT switch on  
the handset or pressing the SQUELCH control.  
1.12 Scanning  
The receiver scans all channels in the selected channel mode in  
ascending channel order, watching CH16 between channels as be-  
low:  
1
16  
2
16  
3
16  
4…  
16  
88  
16  
87  
16  
86  
16…  
To start scanning, press the SQUELCH control. When the receiver  
finds a signal, scanning is stopped on that channel and starts dual  
watch on it and CH16.

1.13 Remarks on Voice Communications  
Automatic acknowledge (DSC operation) is automatically changed  
to manual acknowledge when voice communications begin. (The  
“auto” indication, however, remains on the screen.) This is done to  
prevent break in communications. Automatic acknowledge is au-  
tomatically restored once voice communications are terminated.  
Priority  
The priority of the equipment is as follows: DSC section of FM-  
8700>Wing handset>Handset of FM-8700>Remote Station RB-  
700  
Note: Time-out Timer  
The FM-8700 is equipped with an automatic timing device that  
deactivates the transmitter and reverts the transceiver to the re-  
ceive mode after an uninterrupted transmission period of 5 min-  
utes. Please contact your dealer if necessary.

2. DSC TERMINAL OPERATIONAL  
OVERVIEW  
Digital Selective Calling (DSC) is the globally adapted system by  
the ITU-R and IMO for selective calling of coast station and ship  
radio stations. The DSC system is used for both safety and routine.  
The GMDSS requires the use of DSC for distress alerting and safety  
calls.

• Prevent automatic transmission of acknowledge back (ACK BQ)  
in response to an individual call, when no operator is present.  
• Prevent automatic transmission of own ship position data in re-  
sponse to an individual call which requests such data.

* Received * DISTRESS ACK  
ID : 001234567  
ID of station (usually coast station)  
which transmitted DIST ACK.  
Commence voice communications with coast station on CH16.  
1. Provide the following information to the coast station:  
Distress call  
(1) Speak slowly and distinctly, “MAYDAY, MAYDAY, MAY-  
DAY,” pronounced as the French expression “m’aider.”  
(2) This is;  
(3) The name of your vessel and call sign three times.  
Then, begin the distress communications, which consists of:  
Distress communications  
(1) Position in latitude and longitude;  
(2) The name of the distress;  
(3) The kind of assistance desired;  
(4) Any other information which might facilitate rescue, for  
example, length, color, and type of vessel, number of per-  
sons on board.  
2. Indicate the end of message by saying “Over.”  
Some countries do not have sea area A. In this case “ACK” from  
the coast station does not arrive over DSC. Aship nearby will con-  
tact the vessel in distress over CH16. After transmitting the dis-  
tress alert, conduct voice distress communications as shown above.

3.4 Receiving Distress Alert from Other Vessel,  
Transmitting DIST ACK Signal  
In no case is a ship permitted to transmit a DSC distress relay  
call on receipt of a DSC distress alert on VHF channel 70.  
Procedure when in area A1  
1. When the FM-8700 receives a distress alert from another ves-  
sel the upper two LEDs (Red) near the [ALARM STOP] key  
blink and the FM-85700 sounds the distress alarm.  
2. Silence the alarm by pressing the [ALARM STOP] key.  
3. Wait up to three minutes until the DIST ACK signal from a  
coast station is received. Be prepared to follow the instructions  
of the coast station.  
4. If you do not receive the DIST ACK signal, follow the flow  
chart shown on the next page.  
If further DSC alerts are received from the same source and the  
ship in distress is beyond doubt in the vicinity, a DSC  
acknowledgement may, after consulation with an RCC or Coast  
Station, be sent to terminate the call.  
Note 1: An asterisk (*) in a received distress alert message indi-  
cates error or unknown at the location marked with the asterisk.  
Note 2: Do not send DISK ACK in response to receipt of distress  
alert having a nature of distress of EPIRB emission.
