21.3. MECHANICAL CLUTCH ON THE PROPELLER
See chapter "Prop Lock Propeller"
21.4. TRIGGER GUARD
The trigger is isolated by a guard that forces the diver to insert a finger in the handle to press the trigger and start
the DPV.
22. RUNNING TIME
Running time data is indicative and is nevertheless referred to use:
with a DPV in perfect running order
in moderate environments
in the absence of currents
with an average load (diver with a double tank 12+12 liters or oxygen rebreather)
in perfect buoyancy conditions
As a rule, the running time should be calculated to cover the descent and ascent. An EMERGENCY running time,
which will vary according to the type of dive, must akso be established.
In any case, when planning a dive you MUST consider the event of returning to the exit point without the
use of the DPV.
23. SPEED
Speed depends on the same factors as running time. The speed chosen should be compatible with the type of dive
and be adjusted to match that of your buddies.
24. PRECAUTIONS FOR USE
Do not expose the DPV to solar radiations, closed into the car under the sun, or exposed to excessive
heat (max 50°C). Overheating and successive deformation may occur, to the prejudice of the water
tightness of mating surfaces.
Avoid bumps during the dive;
Do not direct the DPV toward other divers;
Do not use it as a stool;
Do not stand up on it;
Do not have it used by children or untrained people;
Do not transport it dismantled or open;
Do not attempt to stop the propeller with your hands;
Do not block the starter trigger when the switch is turned to on;
Do not throw it off a boat or the shore;
Do not tow it with motor boats;
Do not dismantle it;
Do not run it dry above water;
Do not wet electrical contacts;
Do not short-circuit the battery;
Do not charge the batteries with a battery charger other than the one supplied;
Do not start the DPV when holding the propeller or with objects between the blades;
Do not remove wires from the connector or invert polarity;
Do not get internal DPV parts and batteries wet.
