Use Only Nikon Flash Accessories

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.
