1. USER MANUAL ENGLISH Welcome new Poseidon divers Here at POSEIDON we are very pleased that you have chosen one of the world s foremost diving regulators POSEIDON has been developing regulators for divers since 1958 Professional divers military divers and techdivers choose POSEIDON equipment because of the high demands they place on our products the same demands you have Your new regulator has been designed to provide you with a life time of pleasure as a POSEIDON diver Our objective is that the equipment you are wearing should not be noticeable instead it should be at one with the experience and give you total freedom to achieve what every diver dreams about the ultimate dive To be at one with the water To have full control and at the same time feel the weightlessness when meter by meter you descent into a world of your own Nothing shall disturb your concentration No wheels or levers that need adjusting No regulators that resist your breathing when you have reached your target depth No suits that limit your freedom of movement or get damaged at the slightest encounter This vision has accompanied Poseidon since the legendary diving enthusiast and engineer Ingvar Elfstr m started the company in the late 50 s The same ideas motivate us now The name Poseidon represents constant development and improvement of diving equipment where everything is positioned correctly and everything functions even in the most extreme situat2. different for different models or if any faults are detected a service Level B is required which is a complete overhaul You can do some fault correcting servicing and or preven tive servicing yourself Following the instructions which co mes with the spare part you are allowed to Replace the diffuser Replace the mouthpiece Replace the hose m 26 XSTREAM sid USER MANUAL ENGLISH Modifications of the product are prohibited Modifications can impair the function of the regulator and transfers the responsibility to the person who does the modification Adding decals and other outer means for oxygen Nitrox identification as well as marking with a pen is not regarded as mo difications WE INTEND TO CO DIVING EQUIPMENT DROPOF NTINUE TO PRO AS LONG ATERREMAINS IN Box 8050 S 421 08 V stra Fr lunda SWEDEN t 46 0 31 7342900 f 46 0 31 7342901 www poseidon se Art no 4695 ISSUE 040924 3
