Dive rite IP adjustment

[NorthWoodsDiver]

I am borrowing a dive rite reg for an ice dive tomorrow because mine are out getting serviced but this reg is brand new and the IP is at 152psi and I want to turn it down but the allen socket point where I assumed was the point of adjustment does not seam to turn so I thought maybe this reg had a different point of adjustment compared to my scubapro regs. Any advice on this is much appreciated. Thanks

The regs I have are setup with the dive rite ice dive kits which hide the adjustment screw and I would need a spanner to remove that so oh well.
