Using Fully Automatic Wireless Flash
Flash exposure compensation and other settings set with the master unit will
also be automatically set in the slave units. Thus, you need not make settings
on the slave unit(s). Wireless flash with the following settings can be done in
the same way as with normal flash shooting.
• Flash exposure compensation
• High-speed sync (FP flash)
• FE lock
• FEB
• Manual flash
• Stroboscopic flash

With FE lock, if even one Speedlite will result in underexposure, the
<~

the viewfinder. Open the aperture more or move the slave unit closer to the subject.

channel No. to prevent signal confusion. Both the master and slave units must
be set to the same channel No.
