conditions. A specially designed fr ont cover offers maxi-
mum protection to the diaphragm and minimizes the side
effect of strong currents. The VR / VR T / VR Iceberg / VR
NITROX second stage comes fr om factory with adjust-
ment knob (except VRT) and lever in the minus position.
C > Venturi lever
This lever, located on the side of the second stage
Housing, enables the diver to contr
Venturi effect. When on the + position, the diver get
maximum Venturi assistance upon initial inhalation, the
air flow is maintained without additional ef fort.
Important : On the surface to avoid any fr ee flow resul-
ting from surface waves and / or sudden entry in the
water , the diver should keep the lever pushed towar ds
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

D > INHALATION RESISTANCE (Except VRT)
This knob, located on the left hand side of the VR / VRT /
VR Iceberg / VR NITROX hosing, allows to adjust the resis-
tance on the VR / VRT / VR Iceberg / VR NITROX spring and
thereby to alter the initial br eathing resistance. The diver
can choose any position between 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 incr ease the inhalation resis-
tance, turning it counter clockwise will decrease the inha-
lation resistance. When the inhalation resistance knob is in
the minimum position, ther e may be a light fr ee flow. If
this is the case, slightly tur n the knob clockwise until the
air flow stops. Or have your r
authorized BEUCHAT dealer.
