Wireless multiple flash operation in the Nikon Creative Lighting System (CLS)
When the SU-800 is used with Nikon CLS-compatible cameras, the remote flash
units can be divided into a maximum of 3 groups, and the flash output level can
be separately set for each group of Master/Commander and remote flash unit(s),
providing wireless multiple flash operation (Advanced Wireless Lighting).

Master flash unit and remote flash unit(s)
In this user’s manual, the Commander SU-800 and Speedlight mounted on the
camera, a built-in flash or the one directly connected to the camera via a TTL
Cord is called the Master/Commander flash unit. All other flash units are called
remote flash units.
Details of Advanced Wireless Lighting
• Remote flash units can be divided into a maximum of three groups (A, B and C).
• One or more remote flash units can be set to one group.
• Flash mode and flash output-level compensation values can be set independently on the
Master/Commander flash unit and for three other groups of remote flash units.
• Select one of the four available channels through which the Master/Commander flash unit
and three other groups exchange data.
• If a photographer performs the same Advanced Wireless Lighting near you, your remote
flash unit(s) might accidentally fire in sync with that photographer’s master flash unit. If
this happens, select a different channel number.
