Distress Alert Calling Procedure

Below is the procedure for transmitting a distress alert via radiotelephone. Transmit the distress alert when a life-endangering situation occurs on your vessel.

1. Open the DISTRESS button cover and press the [DISTRESS] button more than three seconds to show the following display, then release the [DISTRESS] button.

Distress call in progress!

NATURE: UNDESIGNATED

12˚34N 123˚45E AT 12:34

POS: TELEPHONE

DSC FREQ : TIME TO GO : 30S

2. After the distress call has been transmitted, the following displays appear in order.

2182.0 KHZ

2187.5 KHZ

Wait for distress acknowledgement.

NATURE: UNDESIGNATED

3. The audio alarm sounds; press the [CANCEL] key to silence the alarm.

4. Communicate with the coast station via radiotelephone as below. (In the dual control

unit system, communication can be done from any control unit, after the distress alert has been transmitted. To restore priority to the #1 control unit after completion of distress communications, turn it off and on again.)

a) Say MAYDAY three times. b) Say “This is …” name of your vessel and your call sign three times. c) Give nature of distress and assistance needed. d) Give description of your vessel (type, number of persons onboard, etc.) and any other

information which may aid in rescue.

SAFETY INSTRUCTIONS

DANGER

Never touch the SSB antenna, antenna coupler or lead-in insulator when the SSB radiotelephone is transmitting.

High voltage which will cause death or serious injury is present at the locations shown in the illustration below when the SSB radiotelephone is transmitting.

WARNING

ELECTRICAL SHOCK HAZARD

Do not open the equipment.

Only qualified personnel should work inside the equipment.

Immediately turn off the power at the switchboard if water leaks into the equipment or something is dropped in the equipment.

Continued use of the equipment can cause fire or electrical shock. Contact a FURUNO agent for service.

Do not disassemble or modify the equipment.

Fire, electrical shock or serious injury can result.

Immediately turn off the power at the switchboard if the equipment is emitting smoke or fire.

Continued use of the equipment can cause fire or electrical shock. Contact a FURUNO agent for service.

Do not operate the equipment with wet hands.

Electrical shock can result.

CAUTION

Use the proper fuse.

Use of the wrong fuse can cause serious damage to the equipment and void the warranty.

CAUTION

Do not operate the [DISTRESS] button except in case of a life-endangering situation on your vessel.

If the distress alert is accidentally transmitted, contact the nearest coast station and inform them of the accidental transmission as follows:

a) Ship's name b) Ship's call sign and DSC number c) Position at time of transmission d) Time of transmission

WARNING LABEL

A warning label is attached to the transceiver unit and a danger label is attached to the antenna coupler. Do not remove the labels. If a label is missing or illegible, contact a FURUNO agent or dealer about replacement.

WARNING

To avoid electrical shock, do not remove cover. No user-serviceable parts inside.

1 OPERATIONAL OVERVIEW

1.10 Power Supply Unit (option)

The control unit works directly on 24 VDC or through a Power Supply Unit on AC mains supply (115 or 230 VAC). The power supply unit is type PR-300, supplying 24 VDC power (20 A) to the FS-1570 or type PR-850A, supplying 24 VDC (40 A) to the FS-2570. Both 115/230 VAC and 24 VDC power can be connected simultaneously. In this case, the system normally operates on the AC mains supply and when AC power is lost, the PSU automatically switches to the DC power source.

This power supply arrangement satisfies the GMDSS requirements. The FS-1570/FS-2570 can be operated directly from 24 VDC without a power supply.

OVEN power supply: The crystal oven is always powered even when the Power Switch is OFF, provided the mains switchboard is turned on.

AC and DC power switches

Both AC and DC power switches on the PSU can be always kept on. (These switches are provided to turn off the power supply for maintenance.) The control unit may be turned on or off with the PSU kept on.

2. Enter frequency by one of the methods below.

Entering frequency with the numeric keys:

Use the numeric keys to enter frequency and then push the [ENTER] knob. Be sure to including trailing zero. For example, to enter 2161 kHz, key in [2], [1], [6], [1], [0]. (Keying in 2-1-6-1 will set 216.1 kHz.)

Choosing frequency with the ENTER knob (for RX only):

a) Use the [FILE/CURSOR] key to choose digit to change. b) Rotate the [ENTER] knob to set digit. c) Push the [ENTER] knob.

Note: To enter same frequency for both TX and RX, enter the TX frequency first.

2.1.3 Tuning

Maximum transmission power is achieved only when the antenna impedance and transmitter impedance match each other. Because the antenna impedance changes with frequency, a means must be provided to match (tune) the antenna impedance with the transmitter impedance. This is done with the antenna coupler. The antenna coupler automatically tunes the transmitter to a wide range of different antenna lengths, from 7 to 30 m.

To initiate the automatic tuning, do the following:

1. Press the PTT switch on the handset or the [LOG/TUNE] key on the control unit.

“TUNING” appears when the [LOG/TUNE] key is pressed; “TX” pops out when the PTT switch is pressed.

Tuning will be completed within 2 to 5 s for a newly selected frequency, or less than 0.5 s for a once-tuned frequency. (A memory saves coil and capacitor settings.) When the tuning process is successfully completed, TUNE: OK appears. If tuning fails, TUNE: NG appears.

2-3

2 SSB RADIOTELEPHONE

Note: When tuning is initiated in the two-control unit system, the display of the idle control

unit shows “OCCUPIED(ANOTHER CONTROLLER).” In this case, only the DISTRESS button is operative on the idle control unit. Further, if a control unit is in use when tuning is attempted at the other control unit, the display of the control unit which attempted to tune shows “OCCUPIED” plus the name of the equipment in use: ANOTHER CONTROLLER, NBDP, or DMC.

2.1.4 Using the handset

Hold the handset close to your mouth, press the PTT switch and speak clearly.

2.1.5 Monitoring transceiver output power

During transmission, the IA bar deflects according to the current being fed to the antenna feeder from the antenna coupler. The unit of readout is amperes. The antenna current varies with the effective antenna impedance. The swing differs by the frequency and antenna length. The output power is proportional to the square of an antenna current.

Note: If IA is not shown, follow the procedure in paragraph 2.1.7 to show it.
