the front in the - minus position. This position should be
maintained whenever the second stage is used as an
octopus for a safe second stage.
At the beginning of the dive, the diver should push the
Venturi lever in the + / plus position, to obtain optimum
breathing characteristics. The + / plus position is the "dive
mode" position.
D > INHALATION RESISTANCE
This knob, located on the left hand side of the VX 200
Iceberg hosing, allows to adjust the r esistance on the VX
200 Iceberg spring and ther eby to alter the initial br ea-
thing resistance. The diver can choose any position bet -
ween the minimum (tur ned completely counter clock
wise) and the maximum (tur ned completely clock wise)
depending on the conditions. tur ning the knob clockwise
will increase the inhalation r esistance, turning it counter
clockwise will decr ease the inhalation r esistance. When
the inhalation resistance knob is in the minimum position,
there may be a light fr ee flow. If this is the case, slightly
turn the knob clockwise until the air flow stops. Or have
your regulator checked by an authorized BEUCHAT dealer.
