1) Apply the foam ring supplied with your mounting kit to your PX Receiver around the window on the back of the
receive marked by the green circle. This foam ring exists to seal the slight gap between the PX Receiver and your slave
flash so that outside light signals do not enter the light sensor of your slave flash.
2) Try moving the Slave flash significantly out of view of the Master flash - place it in another room or down a hall and
attempt to operate the system. If your Slave flash operates reliably when significantly out of view, then becomes erratic
the same room or small space, then check there are no gaps between the PX Receiver and the light sensor of your slave
flash.
3) Regarding Nikon SB-900, SB-800, and SB-600 Speed Light units: In these units, the physical internal space of the
flash is somewhat open, such that light coming in through the red focus assist window may reflect around the inside of
the flash and still reach the wireless light sensor from the inside. When properly mounted, interference due to crossed
signals is rarely observed and only at close range. If your situation does require placing the Slave flash at close range and
oriented such that the red focus assist window is pointed directly at the Master, place a piece of tape covering the red
window entirely. This will eliminate any light leakage internal to the flash and will allow reliable operation even at very
close ranges.
