Troubleshooting
If the built-in wide-flash adapter is broken off accidentally
The wide-flash adapter may break if subjected to a strong shock while on the
flash head.
In this case, contact your retailer or Nikon representative.
When the wide-flash adapter is broken off, it is no longer possible to set the
zoom position to the desired position. To adjust the zoom position, go to the
custom setting “Zoom position setting if the built-in wide-flash adapter is
broken off accidentally” (kC-25).
Microcomputer characteristics
The SB-900 incorporates a microcomputer to control flash operations. In rare cases,
the SB-900 may not work properly even after fresh batteries are properly installed.
If this happens, replace the batteries while the SB-900 is turned on.
