About Phottix System

1-1. How to use L-478DR-PX Series with Phottix System Products Plug-in external or built-in Phottix receivers are required to work with the Phottix radio
system.
Radio triggering enables a single photographer to easily trigger and control flash units.
The radio transmitter built into the L-478DR-PX Series is only compatible with the Phottix radio system.
Please read the instruction manuals provided with these products for details about using them.
Please go to www.phottix.com/ to learn more about their products and compatibilities.

• Successful radio triggering depends on several factors. Please read these setup steps before using the L-478DR-PX Series to radio trigger flash units.

1. It is best to position the meter in sight of the radio receiver.
2. Position the radio receiver so that it is away from large metallic objects, concrete, or containers of water (like people).
3. When triggering a studio-type flash using the connecting cables included with the Strato II set, be sure to position the Strato II within line of sight so that the Strato II is above the flash body or generator pack.
4. Sometimes, conditions do not allow radio reception. These could include strong local radio interference or be near objects that block or absorb the signal. Repositioning the radio, even slightly, can re-establish contact. Alternatively, check to see if the radio receiver is behind objects that absorb or block radio waves, such as concrete, metal, or low hill.
5. Operation is the best when the meter to receiver distance is within 30 meters. The working distance of the radio triggering system can vary with the orientation and location of the meter and receivers.
