Nikon SB-16 instruction manual With the SB·16A

-CONTROLS IN DETAIL-continued---------

With the SB·16A

As soon as the flash unit is turned on, both ready·lights blink in the following cases :

1)When the AS-8 's mounting foot is not securely locked.

2)When using the TTL mode with the Nikon F3-series camera and the camera 's film speed setting is set well beyond the usable range of ASAIISO 25"'400, without exposure compensation .

3)Wh en the shooting mode selector is set at TTL with any camera other than the Nikon F3-series .

Note that when the shutter speed setting on the Nikon FE or FM2 is improper for correct flash synchronization and the camera 's meter is on (only in the case of the FE), just the camera 's ready- light blinks as a warning, while the one on the flash unit does not blink but simply lights up to indicate when the flash is ready to fire.
