1.2 Telephone Operation
Turning the power on and off
To turn the power on, turn the VOLUME control clockwise until
you hear a click. To turn the power off, turn the control fully counterclockwise until you hear the click.

Selecting channel modes
While pressing the channel selector, press the CH16 key to select
the channel mode, International, USA (in the case of USA version), private (if authorized), or weather mode (USA version). The
International version of FM-8500 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) until a desired channel is reached.

Adjusting volume
The VOLUME control adjusts the volume of the loudspeaker.

Adjusting squelch
The SQUELCH control adjusts the squelch threshold level. Adjust
it so that white noise heard in the loudspeaker just fades out. Perform this operation when no traffic is being received. AUTO squelch
automatically reduces white noise. Usually select "AUTO" position. 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.
Every press of the SQUELCH control changes the function as follows:

Transmitting
Press the PTT (Press-to-talk) switch on the handset or microphone
to talk, and release it to listen for the response.

Output power
• BEFORE transmitting, think about the subjects which have to be communicated and, if necessary, prepare written notes to avoid unecessary 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.

Each press of the [HI/LOW] key selects HI or LOW output power.
The transmitter power is automatically set for low on the following channels.
International:

CH15, CH17

USA:

CH13, CH15, CH17, CH67; to operate USA channel 13 or 67 in high power, keep [HI/LOW]
pressed while talking into the handset.

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 loudspeaker is automatically turned off when the telephone handset is
used on semi-duplex channels.

Channel 16
Press the [CH16] key to select channel CH16, International Calling and Safety Channel.
This is an international calling and safety channel. The use is limited for 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 Channel 16 for purposes other than distress, urgency and very brief safety communications when another calling
channel is available.

1-4

Dual watch
The dual watch allows you to keep watch on channel 16 and another channel. CH16 and another channel are watched at intervals
of 0.15 seconds and one second, respectively.
To start DW, press the SQUELCH control once. When the receiver
finds a signal on channel 16, it locks on CH16 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.

Scanning
The receiver scans all channels in the selected channel mode in
ascending channel order, watching CH16 between channels as below:
To start scanning, press the SQUELCH control and SCAN is started.
When the receiver finds a signal, scanning is stopped on that channel and starts dual watch on it and channel 16.

3.3 Receiving Distress Alert from Other Ship
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.
Conditions necessary for relaying distress alert:
1 When the station in distress is not itself in a position to transmit
the distress message, or
2 When the master or person responsible for the vessel not in
distress, or the person responsible for the coast station, considers that further help is necessary.

Procedure when in area A1
1. When the FM-8500 receives a distress alert from another vessel the upper two LEDs (Red) near the [ALARM STOP] key
blink and the FM-8500 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

3.4 Distress Relay
General
If a vessel in distress is obviously near own ship and is not able to
transmit the distress alert by itself, you can relay (transmit) the
alert on behalf of the vessel in distress. You may relay a distress
alert in the following conditions;
1When the station in distress is not itself in a position to transmit
the distress message, or
2When the master or person responsible for the vessel not in distress, or the person responsible for the coast station, considers
that further help is necessary.
However, DO NOT press the [DISTRESS] key; it is for use when
own vessel is in distress.
