1. USER MANUAL ENGLISH THE ULTIMATE DIVE Buoyancy compensating is achieved by inflating and deflating the BESEA bladder Inflating the bladder using the power inflator is done by depress ing the inflator button using short bursts Continuous depressing of the button can cause you to become excessively buoyant Orally inflating of the bladder is achieved by exhaling a small amount of air into the inflator Place your lips on the inflator mouthpiece and exhale while depressing the oral inflation button After exhaling release the oral inflation button to prevent air from escaping Deflating the bladder is done by using either the inflator s oral inflation button or any of the APRV s For deflation using the inflator oral inflation button hold the infla tor in an upright position so that it becomes the highest point of the bladder and depress the oral inflation button Deflation of the bladder using an APRV is done by activating the valve that is placed on the highest portion of the bladder depend ing on the diver s attitude during the actual period of time The two APRV s placed on the rear lower portion of the bladder are activated by pulling the knob For activating the inflator integrat ed MDV pull the inflator as if to extend the corrugated hose INING _ In case of inflator malfunction or freezing the inflator might con tinuously inflate the bladder Start by detaching the inflator hose and continuous2.
