Max. number of continuous firings
Notes when using the SB-400 with D90, D80, D70-Series,
D5000, D3000, D60, D50, D40-Series or COOLPIX 8800 cameras
When using the SB-400 with D90, D80, D70-Series, D5000, D3000, D60,
D50, D40-Series or COOLPIX 8800 cameras, the SB-400 must be turned on.
• If the SB-400 is turned off while mounted on any of the above cameras, and the
camera's "Auto flash" function is on, the camera's built-in flash will automatically
pop up when shooting in poor light, coming into contact with the SB-400.
• It is recommended that the SB-400 be detached from the camera when flash is
not required.
A note on microcomputer-controlled Speedlights
The Speedlight incorporates a microcomputer to control flash operations. In
rare cases, the Speedlight may not work properly even after a fresh battery is
properly installed. If this happens, replace the battery while the Speedlight’s
power is turned on.
