1) The manual states that this reg is compatible with only a 21% mix. Does this mean that some type of service is required for it to be used with Nitrox?
2) The user-adjustable knob for fine tuning the effort required to intake air, in one direction (towards the front of the reg) it comes to a complete stop. In the other direction (towards the diver) it just turns and turns forever with a small click now and then. Is this normal or do I have a defective reg somehow?
Thanks
