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 op-

eration 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 an-

tenna works for transmitting and receiving and the 2nd antenna for

watch keeping.

Transmitting

Output power

Press the PTT (Press-to-talk) switch on the handset or microphone

to talk, and release it to listen for the response.

• 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.

Each press of the [HI/LOW] key selects HI or LOW output power.

The transmitter power is automatically set for low on the follow-

ing 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.

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.

Channel 16

Press the [CH16] key to select channel CH16, International Call-

ing and Safety Channel.

This is an international calling and safety channel. The use is lim-

ited 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, ur-

gency 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 an-

other 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 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.

Scanning

The receiver scans all channels in the selected channel mode in

ascending channel order, watching CH16 between channels as be-

low:

To start scanning, press the SQUELCH control and SCAN is started.

When the receiver finds a signal, scanning is stopped on that chan-

nel 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 re-

ceive mode after an uninterrupted transmission period of 5 min-

utes.

Remarks on voice communications

Automatic acknowledge is automatically changed to manual ac-

knowledge when voice communications begin. (The "auto" indi-

cation, however, remains on the screen.) This is done to prevent

break in communications.Automatic acknowledge is automatically

restored once voice communications are terminated.

Priority

The priority of the equipments is as follows.

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, consid-

ers 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.

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.

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 dis-

tress, 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.
