Sekonic Module
Quick Start Guide
Thank you for purchasing the RadioPopper
compatible transmitter module. This module may
be installed into the following Sekonic brand light
meters: L-358, L-758D, L-758DR, L-758Cine, C-500R
Installation Instructions
1) Remove the battery cover from the back side of
the Sekonic light meter. Refer to the picture on the
reverse side of this guide.
2) If your Sekonic light meter already contains a radio
module in the opening (it will look like a small plastic
box set inside the square space above the battery),
carefully remove the existing module. If a module is
not already present, you may see a small cover over
the connecting pins inside the opening. Remove the
cover from the connecting pins if present.
3) Align the connecting pins inside the light meter
with the connector on the back side of the Radio-
Popper module. Carefully press the RadioPopper
module onto the connecting pins inside the light
meter. The RadioPopper module may be removed if
necessary by pulling on the green ribbon.
4) Follow the instructions provided with your
Sekonic light meter to enable Wireless Flash Radio
Triggering Mode. Select a radio channel between
1 and 16. This radio channel will correspond to the
RadioPopper radio channels 1 to 16. The light meter
will automatically set the correct radio channel on
the RadioPopper module.
5) Confirm proper operation of the RadioPopper
module by observing the green light in the lower
right corner of the module. It will blink periodically
to indicate proper operation and that your light
meter is configured correctly. Each time you trigger
your meter to take a light reading, this green light
will strobe momentarily as your wireless lights are
activated.
6) Replace the battery cover on your Sekonic light
meter. You’re all done. Happy metering!
