Press the
ENTER
key to make the call. The
DSC1400 will require confirmation of the call.
Press
Yes
to send the call, or
No
to cancel.
When the DSC call is sent, the RT1400 will be
set to the working channel. Allow a few sec-
onds for the stations receiving the call to switch
to the working channel, then make a normal
voice call on the specified working channel.
2.4 Group Call
If a group ID has been set up for the DSC1400
(see section 4.7), a call can be made to other
members of the group.
Press the
Call
key four times to select the Group
Call screen. Select a working channel from the
list (see section 4.10) by pressing the channel
softkey or use the RT1400 channel select knob
(Fig 1.7).
Press
ENTER
to send the call, allow a few sec-
onds for the other members of the group to
reach their radios (all VHF radios in the group
should automatically switch to the specified
working channel upon acknowledgement),
then make a normal voice call using the work-
ing channel.
2.5 Distress Alert
NOTE - THIS CALL SHOULD ONLY BE
MADE IF THE VESSEL IS IN A DISTRESS
SITUATION.
It is an offense to send a Distress
Alert call if the vessel or crew are not in danger.
Refer to section 5.1 for more details.
Lift the protective cover and press the
DIS-
TRESS
button. The Distress Alert Screen will
be displayed. If time permits, press the des-
ignation softkey to select the nature of the dis-
tress. There are 10 categories recognised as
Distress Alert situations, which are -
Abandoning, Adrift, Collision, Fire, Flooding,
Grounding, Listing, Man Overboard, Piracy
and Sinking. There is also a default
Undesignated category, which is used if no cat-
egory is selected here.
Press and hold the
DISTRESS
key a second
time, holding it down for five seconds (Fig 1.8).
An alarm will sound and a countdown to the
transmission will be displayed.
The Distress Alert transmission contains the
following data -
* The vessel's MMSI
* The vesselÕs position (either from the
NMEA0183 input, or manually entered)
* The time (from NMEA or manual)
* The nature of the distress
After the Distress Alert has been sent, the
RT1400 will automatically tune to channel 16
and the DSC1400 will repeat the Alert approx-
imately every four minutes until either an
acknowledgement is received, or
C
is pressed
(it is not recommended that the Distress Alert
is cancelled manually by pressing
C
unless
you are requested to do so by the rescue
authorities).
While the Distress Alert remains active, an
intermittent alarm will continue to sound.
When an acknowledgement is received from
the Rescue Co-ordination Centre, this will can-
cel the Distress Alert transmission from the
DSC1400 and automatically switch the RT1400
to the required working channel. The subse-
quent rescue co-ordination will be performed
using the voice working channel.
