RadioPopper PX - Manual (Page 6)

Installation: RadioPopper PX Transmitter
1) Remove the battery compartment door on the top side of the unit.
2) Remove the cover and insert two (2) AAA size batteries into the battery holder. It is very important to follow the
polarity direction indicated on the inner sticker to ensure unit operation and avoid possible transmitter damage.
3) Replace the battery compartment door. Once batteries are inserted, the battery door should fit snug.
4) Select the approximate mounting location on top of your Master Flash or IR Commander (supplied by your camera
manufacturer). Ensure this area is clean.
5) Attach the Velcro pieces together. Remove both backing sheets and affix the joined Velcro strips first to the under
side center of the PX Transmitter unit. We recommend placing the “rough” hook side of the Velcro against the transmit-
ter, and the soft side of the Velcro against your flash or IR commander.
6) Hold the PX Transmitter with Velcro attached over the approximate mounting location on the intended Master flash
unit. Compare location to the picture in Fig 2.1 on page 13. Press down firmly and hold pressure for thirty seconds to
tightly bond the Velcro strip adhesive to both the Master flash unit and the under side of the PX Transmitter.
7) Do not pull the Velcro apart for several hours. The adhesive on the Velcro will set to full strength in 20 to 30 hours.
Care should be taken during this time to avoid upsetting the bond being formed between the Velcro and plastic to
ensure maximum long term adhesion.
8) Install the supplied antenna (the straight one) by screwing it onto the antenna connector on the face of the PX
Transmitter.
WARNING: Do not power up the PX Transmitter without the antenna installed - doing so could damage the output
stage of the radio transmitter.
WARNING: Use only the supplied antenna on the PX Transmitter. Using any other antenna is a violation of Federal
Law, and may actually cause damage to the output stage of the radio transmitter.
9) When mounting the PX Transmitter in the future by pressing the Velcro pads together - a greater bond may be
achieved between the Velcro hook and latch sides by pressing firmly, then applying a slight rotational force between
the Master flash unit and the PX Transmitter. This tends to “set” the Velcro pads together.
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.
