[. . . ] The R290 has a preset moderate Venturi effect which prevents the unwanted free flow: it can be adjusted by an Authorized Scubapro repair technician to the personal requirement of the diver. Use and maintenance (see point 8-9-10-11 on the manual). 5. 22 2nd Stage R295 This second stage is the R290's natural evolution. The main innovations are the greater performances due to the new lever and the new diaphragm with the new disc that allows a lower friction. The new shape of the lever offers a more progressive and constant air flow. The R295 can be assembled with the LP hose either on the right or on the left side. The R295 has a preset moderate Venturi effect which prevents the unwanted free flow: it can be adjusted by an Authorized Scubapro repair technician to the personal requirement of the diver. Use and maintenance (see point 8-9-10-11 on the manual). 5. 23 2nd Stage R390 This second stage is the R190's natural evolution which is the most popular regulator in the world for maximum reliability and performances. only) and reduced size (25% smaller) are the two remarkable improvements of this unit, still maintaining, or rather, optimizing all the R190's features. The R390 allows to personalize the Venturi effect, by simply adjusting a lever (fig. A decrease in breathing assistance can be an advantage when entering the water or when descending head first. Use and maintenance ( see point 8-9-10-11 on the manual). 5. 24 2nd Stage R395 This second stage is the R390's natural evolution. The main innovations are the greater performances due to the new lever and the new diaphragm with the new disc that allows a lower friction. The new shape of the lever offers a more progressive and constant air flow. The R395 can be assembled with the LP hose either on the right or on the left side. I - 13 User Instructions for Breathing Regulators The R395 allows to personalize the Venturi effect, by simply adjusting a lever (fig 3 ­ see point 5. 14 V. I. V. A. ). A decrease in breathing assistance can be an advantage when entering the water or when descending head first. Use and maintenance (see point 8-9-10-11 on the manual). 5. 25 2nd stage S600 / CLASSIC /S600T In this model, all SCUBAPRO® features developed from many years of experience have been concentrated in order to offer the best comfort, performances and durability, in a pleasant design. Lightweight, reduced size, anti-icing system, orthodontic mouthpiece, are some key aspects of this project as well as the inhalation and vacuum assist control (V. I. V. A. ), the pneumatically balanced poppet and a new design. These are the SCUBAPRO® lightest second stages, thanks to the use of carbon fibre and TITANIUM (with the S600T). - Pneumatically balanced: pneumatic balancing is made possible by a small longitudinal bore hole through the seat and poppet assembly. This allows air to pass into a small chamber at the far end of the piston. The air trapped chamber provides a counter force moving the piston back against the intermediate pressure port, balancing out the forces trying to open the valve. This permits the use of a softer spring and provides a smoother action under all conditions. [. . . ] 4. - Let the regulator dry in a ventilated location away from direct sunlight. (MK25 S.
