RESISTANCE CONTROL KNOB
This knob adjusts the spring load on the second stage valve and so var-
ies the initial inhalation effort. To adjust the Resistance Control Knob to
the easiest breathing setting, turn the knob fully counter-clockwise (fig. 6).
Sometimes a slight hissing flow of air may be heard at this setting. If this
occurs, turn the knob clockwise (fig. 7) just enough to stop the hissing.
DIVE / PRE-DIVE VENTURI LEVER
This lever controls the sensitivity of the regulator. The Plus and Minus
Positions for the lever are marked on the case beside the lever. To
avoid unexpected venturi free flows at the surface, or when jumping
into the water, the lever should be set in the PRE-DIVE “-” (forward)
position. As soon as the diver is ready to descend, the lever should
be moved to the DIVE “+” (back) position.
NOTE: Ask your authorized Zeagle Scuba dealer for in-store instructions
and training on the use of the second stage Resistance Control Knob
and lever. Your dealer will show you how to make adjustments to get
the desired breathing results. To actually experience the effects of the
adjustment range, the instruction should be conducted with the diver
breathing through a regulator attached to a full air supply. The feel of the
regulator breathing underwater is of course somewhat different from the
feeling of breathing above the surface.
