Technical operation/Effective Speedlight placement
lWireless master flash unit
m The SB-80DX, when set as a wireless master flash unit, can be used as a
normal flash unit, but Monitor Preflashes will not fire even if Automatic
Balanced Fill-Flash with TTL Multi-Sensor is selected.
m Use of a wireless master flash unit set to the TTL auto flash mode is
recommended. With Nikon Digital SLRs cameras, use a wireless master flash
unit set to the Auto Aperture or Non-TTL auto flash mode.
lWireless slave flash unit
m When the flash unit is used off-camera, the wireless slave flash mode is
activated and the indication toggles between P (auto) and P (manual)
mode every time you press the a button.
A (auto) mode:
m The wireless slave flash unit starts and stops firing in sync with the master
Speedlight.
m The maximum shooting distance of the SB-80DX’s light sensor is approx.
7m (23 ft.).
M (manual) mode:
m The wireless slave flash unit only fires in sync with the master Speedlight.
m The maximum shooting distance of the SB-80DX’s light sensor is approx.
40m (131 ft.).
m The flash output level can be set from M1/1 to M1/128.
Note
nDo not leave the power of the wireless slave flash unit on—this includes Speedlights
mounted on the SU-4. Otherwise, ambient electric noise due to a discharge of static
electricity, etc. may accidentally trigger the flash.
How to prevent accidental flash firing
m Press the Modeling illuminator button on the SB-80DX to avoid accidental
firing in sync with other Speedlights. The SB-80DX will not fire, while this
button is pressed.
