PREMATURE DIVE
: To cover the situation where the diver needs to dive early, for example,
when the diver has dropped something or sees a fish (before 15 seconds have elapsed), we have
programmed the FRV with a Premature Dive State. A Premature Dive occurs when you descend
below 3 meters (10 feet) BEFORE the FRV is cleared. (Even with Surface Minder Off, you cannot
clear the FRV for the first 10 seconds.) Upon reaching 3 meters, the remote light will begin to blink
You then have 15 seconds to acknowledge that this dive is intentional by pressing the remote button,
which will TEMPORARILY clear the FRV for 15 seconds (perhaps enough time to catch some sinking
gear or fish or avoid a boat.) After 15 seconds, the LED again resumes blinking. A premature dive
may be continually extended but will end either if you fail to respond, in which case the FRV will
deploy, or you ascend above 1 meter, at which time a new surface interval is started, complete with
the 15-second surface timer. The premature dive only occurs before you clear the FRV. In the case of
Surface Minder On, any dive made before the end of the 15-second surface interval AND before you
have cleared the FRV, will cause a premature dive. With Surface Minder Off, as soon as you clear the
FRV, or after it has automatically cleared, you are free to dive and the premature dive will not occur.
Study the Premature Dive concept well because this is the mode that frequently leads to unintended
inflations by new users. Get used to taking a look at the remote light for reference. For the Surface
Minder On option, it will tell you when to press the acknowledgment button. With Surface Minder Off,
you can clear the FRV with a button press after 10 seconds and then not have to worry about entering
Premature Dive Mode if you need to re-dive soon after 10 seconds from surfacing.
COMMAND INFLATION BY PRESSING THE REMOTE BUTTON:
Any time while diving, or when
the FRV is cleared, you may command your FRV to inflate. Simply press the remote button 4 times
rapidly. To prevent the buttons from “accumulating” or storing pushes throughout the dive (for
example, bumping something and pushing a button), this sequence must be completed in 5 seconds.
COMMAND INFLATION BY PULLING THE MANUAL CORD:
A pull handle, located on the left lapel
connects to the manual activation cord. A quick pull on this cord, with a force of about 10-20 pounds,
will trigger inflation by manually tripping the actuator trigger.
ORAL INFLATION:
While you are on the surface, you may also inflate the FRV by using the oral inflation tube behind the
right lapel. To manually inflate the FRV, open the right lapel pouch by unsnapping it to expose the
oral inflation tube. Rotate the lock cap several times counterclockwise to allow downward movement
and then blow into the hose while at the same time pressing down against the spring-loaded valve.
