Miscellaneous

• Microcomputer of the SB-50DX

The SB-50DX is electronically controlled by a microcomputer. In certain cases,

the microcomputer may not correctly control the SB-50DX even with fresh,

properly installed batteries. In the same way, incorrect indications may appear in

the LCD panel. In each of these cases, to resume operation, remove and

reinstall the batteries with the SB-50DX turned on.

• If -- blinks in place of zoom-head position indication

Troubleshooting—continued

• Zoom-head cannot be set.

• Turn off the SB-50DX and camera, detach the

SB-50DX from the camera and reattach it, then

turn both units on. If operation is not resumed,

contact an authorized Nikon dealer or service

center.

TTL auto flash mode are as follows:

position, flash shooting distance range would be 2.0-18 ft.

flash operation with F70-series/N70 or PRONEA

600i/PRONEA 6i cameras; however this does

not indicate any malfunction. See “When using

• When performing double-flash operation with

F80-series/N80-series cameras, Power Zoom
