As the master flash unit, use Nikon Speedlight S8-24, S8-23,
S8-22, S8-218, S8-20, S8-18, S8-168 or S8-15 connected to an F4, F-801/N8008, F-501/N2020, F-401s/N4004s, F-301/N2000, FA, FE2 or FG camera, and for the slave flash unit(s), use the S8-24, S8-22, S8-218, S8-20, S8-18, S8-17, S8-16A, S8-168 andlor S8-15. Up to 5 flash units can be used.
For TTL multiple flash photography, connect the flash units via the speedlight'sTTL multiple flash terminal using optional TTL Multi-Flash Sync Cord SC-18 (1 .5m) andlor SC-19 (3m).
Because S8-23, S8-22, S8-218, S8-20, S8-18 and S8-15 do not have a TTL multiple flash terminal, it is necessary to use TTL Remote Cord SC-17 or SC-24* when using these flash units as a master flash unit. To use S8-22, S8-218, S8-20, S8-18 andlor
S8-15 as slave flash units, use TTL Multi-Flash Adapter AS-l0. When using S8-140, S8-14 andlor S8-11 for TTL multiple flash photography, you should also use TTL Remote Cord SC-23.
* Used for F4 with DW-20 or DW-21 attached.
TTL auto flash is not possible when using Nikon F-401s/N4004s with S8-11/14/140(even with SC-23) or S8-218. These speed- lights cannot be used for TTL multiple flash either, even as slave flash units.
See system chart on the following pages.
•Set the power switch of slave flash units at ON position, not at ST8Y. When using S8-24,S8-22or S8-20as a slave unit with the power switch at ST8Y position, lightly pressing the shutter release button does not activate them. The same thing also happens when you set S8-23to TTL (ST8Y); do not use S8-23as a slave flash unit.
