Nikon Speedlight SB-600 - Manual (Page 17)

Basic operation
In this section, basic procedures are
illustrated so that you can easily perform flash
photography in the TTL auto flash mode.
You can easily perform flash photography by
following Steps 1-6 on the left-hand pages.
The procedures are based on the use of a CPU lens
mounted on cameras compatible with CLS*, digital SLRs
not compatible with CLS*, and cameras in Groups I to II.
The SB-600’s functions and the LCD display vary
depending on the camera/lens combination used.
* CLS: Creative Lighting System (p. 5)
