Additional Functionality
Shearwater® Distress
A diver with a Shearwater® device may issue a Diver Distress
message indicating that he or she is in trouble (Figure 74). This
message will also appear in the question area on the screen to
ensure the Dive Master sees and handles the situation
effectively. When a diver issues the Diver Distress message, the
modem will emit a Morse code SOS signal (3 short beeps, 3 long
beeps, 3 short beeps). Each time the modem receives any
communication from the Topside Modem, this SOS signal will be
emitted. This can be helpful for another diver to hear the SOS
call and head toward the diver in distress.
When the diver cancels the Diver Distress, the modem will stop
beeping and a message will be sent to the Dive Master indicating
the Diver Distress call is complete (Figure 75). The distress cancel
messages will appear in the question area to ensure the Dive
Master recognizes the situation change.
Shearwater® Send Return Home
A diver with a Shearwater® device may issue a diver Send Return
Home message indicating that he or she would like the
directional information to the topside craft. When a diver issues
this command, a message is sent to the Dive Master and the
issuing diver is placed in RECALL mode. In RECALL mode, the
diver is provided with the range and bearing to the topside craft.
When the diver cancels the Send Return Home (Figure 76) a
message is sent to the Dive Master. The diver will be taken out
of RECALL mode and will no longer receive range and bearing to
the topside craft. Normal operation will resume.
Shearwater® Send Assist
A diver with a Shearwater® device may issue a Send Assist (Figure
77) message indicating that he or she needs assistance. This
functionality is to be used in a non-threatening, non-lethal
scenario. When a diver issues this command, the Dive Master is
notified and can then direct the best available diver to the diver
in need.
When the diver cancels the Send Assist the Dive Master is
notified and can make the appropriate adjustments. Normal
operation is resumed.
