1. VHF Radiotelephone Operational Overview

The FM-8500 system consists of a main transceiver unit and two
antennas. The transceiver unit contains a VHF transmitter , receiver ,
and channel 70 watch receiver module. The performance and op­eration are controlled on its front panel. The antenna may be of
any type available from FURUNO or market and the recommended
type is a vertically polarized non-directional type. The first an­tenna works for transmitting and receiving and the 2nd antenna for
watch keeping.

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. T o turn the power of f, 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

Adjusting volume

Adjusting squelch

Rotate the CHANNEL selector clockwise (counterclockwise) un­til a desired channel is reached.

The VOLUME control adjusts the volume of the loudspeaker.

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

Output power

• BEFORE transmitting, think about the subjects which have to be commu­ nicated and, if necessary, prepare written notes to avoid unecessary inter-

ruptions 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.

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

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.

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.

nel 13 or 67 in high power, keep [HI/LOW]
pressed while talking into the handset.

1-4

Avoid calling on Channel 16 for purposes other than distress, ur­gency and very brief safety communications when another calling
channel is available.

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.

Scanning

T o 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 inter ­mittently. If you are annoyed with the intermittence, turn off DW
by pressing the PTT switch on the handset or pressing the
SQUELCH control.

The receiver scans all channels in the selected channel mode in
ascending channel order, watching CH16 between channels as be­low:

T o 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.

Time-out-timer (U.S.A. type only)

The FM-8500 is equipped with an automatic timing device that
deactivates the transmitter and reverts the transceiver to the re­ceive mode after an uninterrupted transmission period of 5 min­utes.

Remarks on voice communications

Automatic acknowledge 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 automatically
restored once voice communications are terminated.

R/S: Relay Specific Ships Call
GRP: Group Call
POS: Position Request Call

2. DSC Terminal

Operational Overview

2. Address: Station’s 9-digit ID number

IDs starting with “00” are coast stations, those starting with “0”
are group IDs or another IDs are ship’s IDs.

3. Category: Communication priority

There are four communication priorities as below:
DIS: A vessel is in grave and imminent danger and requests im-

mediate assistance.

URG: Announce important safety information or request medical

assistance.

SAF: Transmitting a message containing an important navigational

or an important meteorological warning.

ROU: For routine (individual) calling.

4. DSC: DSC channel

A DSC channel is different from the usual communication channel
because it is not used for voice communication but rather DSC and
acknowledging receipt of message.

5. Telecom1: Telecommand

The communication mode; simplex or semi-duplex.

2-1

6. Channel: Voice communication channel

To communicate with a coast station, a station sends its position
data to the coast station and the coast station determines the chan­nel to use. A station may only use CH16 (distress channel) in the
event of distress.

7. Pos: Ship’s position

Position input by radionavigational equipment.

8. UTC: Universal Time Coordination

The equipment contains a clock. External time input from
radionavigational equipment cannot be used.

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 ves-

sel the upper two LEDs (Red) near the [ALARM STOP] key
blink and the FM-8500 sounds the distress alarm.
