RadioPopper PX - Manual (Page 11)

Installation: RadioPopper PX Receiver
NOTE:
It is extremely important that your PX Receiver be mounted in such a way that the
IR light sensor on your Slave flash unit cannot “see” the control signals being sent
by your Master flash unit. The Slave flash must only see the light control signals
being emitted by the light source behind the green circle window on your PX Re-
ceiver. The following steps will insure proper mounting and error free operation.
1) Remove battery compartment cover and insert batteries, just as you did with the PX Transmitter. Replace the
battery compartment cover.
2) Your included PX Receiver bracket will come disassembled in two separate pieces. You will notice that your
mount can be assembled to match various applications depending on which specific flash you are using. Locate the
appropriate notch on the cradle and slide it into place on the base mount. Ensure that the cradle has the support clips
facing outward as shown in Figure 1.1 on page 12.
3) Install the supplied antenna (the one with the 90 degree bend) by screwing it onto the antenna connector on the
face of the PX Receiver.
4) Insert the PX Receiver into the PX cradle so that the optical port is aligned with the hole.
5) Slide your your off-camera flash into the base of your assembled bracket. Remember to lock your flash into place.
Also, take care to align the hole in the foam ring with the light sensor on your slave flash. The foam ring should fully
touch your slave flash in every direction with no gaps. This will ensure your Slave flash unit will only “see” the signals
produced by the PX Receiver, and will not see the signals being sent directly from your Master flash if you are shooting
from a position significantly close to your Slave flash unit(s).
NOTE: The large red transparent piece on the front of your flash is NOT the infrared sensor. In
fact this area has nothing to do with the wireless communication system - it is simply a focus
assist light. The correct sensor is a shiny dark black window on the outside of your slave flash unit.
