Once the base of the mount is fitted to the dive cylinder, the slide mount with the Diver Modem can be
fitted. When fitting the slide mount ensure that the locking pin “snaps” into place to lock the slide onto
the base. If the locking pin does not “snap” into place, the Diver Modem can slide off its mount (Figure
8). To remove the Diver Modem, pull the locking pin out and slide the modem off the base. The locking
pin can be set in the “open” position by
retracting the pin and rotating the knurled knob
90 degrees.
The head of the Diver Modem (the black
molding at the top of the Diver Modem) should
be placed on the cylinder so the head is just
clear of the top of the curvature of the cylinder.
Both the Dive Master and the Diver must check
that they are satisfied with the position of the
Diver Modem. If there is a high entanglement
potential on the dive, consideration should be
given to lowering the Diver Modem to reduce
entanglement potential. The Diver Modem can
be placed low on the dive cylinder but
performance may be diminished by the dive
cylinder creating an acoustic shadow to the
Topside Modem when the diver is in certain
orientations.
The Diver Modem is turned on by pushing down
on the stainless-steel power switch on the
bottom of the modem. The LED will show three
lines
which indicate the modem is booting up. After that the Modem ID will flash 5 times.
The Red dot on the LED will also flash when it receives an Acoustic Signal from the Topside Modem.
It is relevant to note that the Diver6 System can be tested through air over a distance of approximately
100 mm (4”). It does not need to be submersed in order to see if the equipment is working properly. To
get it working, the Topside Modem needs to be placed adjacent to the Diver Modem. When operating
the Diver Modem in air, DO NOT operate at full power. If the Diver Modem is operated at full power in
air, it will shut down and reboot during the transmission cycle. The Diver Modem has been designed to
operate at full power only while submersed.
Interference with Ocean Technology Systems (OTS) Through Water Communications
The Diver6 System operates on one of the frequencies of the OTS through water communications. When
the OTS communications equipment is set to Channel #1 (Buddy Phone Frequency), the Diver6 System
can be heard through the OTS equipment. Selecting another channel on the OTS equipment allows both
the OTS and the Diver6 System to be used at the same time.
