User manual POSEIDON ATMOSPHERE

[. . . ] The name Poseidon represents constant development and improvement of diving equipment where everything is positioned correctly and everything functions, even in the most extreme situations. Products developed in cold Scandinavian waters that are among the toughest you can dive in. If they work here, they will work anywhere. Poseidon's devoted followers are convincing proof of that. [. . . ] The piece can easily be removed and reattached in three different positions to suit the needs of the user. Correct position is achieved when the nasal passages are blocked while upward pressure is applied to the lower part of the mask. Remove excessive material from the piece with a knife if a lower position is needed and place the piece back to its place. Preparation for use 1. Carefully inspect the mask for any signs of deterioration or damage. Check that the visor is clean and free from scratches or blemishes likely to cause distortion or other difficulties with vision. Fully extend all the head harness straps. First check that the dive mode switch on the second stage is in pre-dive mode (-) and then open the cylinder valve. USER MANUAL :: ENGLISH ATMOSPHERE :: 7 Fig. 3 1. Place the neck strap around the neck if required. If the neck strap is not going to be used it should be removed from the mask and not left dangling during use. Invert the head harness over the visor of the mask (fig 3) leaving the face seal area clear, place the chin firmly into the chin cup at the bottom of the mask and pivot the mask up to the forehead. Pull the harness over the back of the head while grasping the lower edge of the center of the harness (fig4). Hold the front fitting of the mask in one hand so as to keep the chin in correct position, tighten the lower straps of the head harness one at a time and then the top strap. Fig. Next, tighten the two center straps and finally check the two lower straps for tightness and adjust if necessary. 6. The straps should be tightened firmly so as to hold the mask securely onto the face. In addition to causing discomfort, over tightening the straps can distort the shape of the mask and reduce the ability to seal to the face.
