Use only Nikon flash units. Negative voltages or voltages over 250 V 
applied to the accessory shoe could not only prevent normal 
operation, but damage the sync circuitry of the camera or flash. Before 
using a Nikon flash unit not listed in this section, contact a Nikon-
authorized service representative for more information.

A sync cable can be connected to the sync 
terminal as required. Do not connect 
another flash unit via a sync cable when 
performing rear-curtain sync flash 
photography with a flash unit mounted on 
the camera accessory shoe.

A

Unified flash control allows the camera and flash unit to share settings. 
If a flash unit that supports unified flash control is mounted on the 
camera, changes to flash settings made with either the camera or flash 
unit are reflected on both devices, as are changes made using optional 
Camera Control Pro 2 software.
