Getting Started — SB-25 Set-Up
This section introduces preparations for using the SB-25,
such as installing batteries, attaching flash unit to your cam-
era, and finally, turning the unit on. Follow these steps in
order, especially when using for the first time. This section
should serve as a practical guide for later reference.
WARNING — TO AVOID INJURY
• DO NOT FIRE FLASH NEAR THE EYES: Firing the flash
light very close to any person’s eyes can injure the retina,
thereby weakening eyesight or causing blindness.
• DO NOT TOUCH THE FLASH HEAD WHEN FIRING THE
SB-25: The flash head generates significant heat during
normal operation, which may cause burns. Also, when
using the flash, keep delicate materials away from the
flash head.
CAUTION — TO PREVENT
DAMAGE TO THE SB-25

FACTURER’S CAMERAS, FLASH UNITS, OR ACCES-

Selecting Measurement System, Meters or Feet
1
Slide the battery chamber cover in
the > direction and lift to open.
ABNORMAL LC (LIQUID CRYSTAL) DISPLAY AND
MALFUNCTIONING
In certain cases, due to normal characteristics of the
built-in microcomputer, the speedlight may not oper-
ate or an abnormal display may appear, even with
fresh, properly installed batteries.
If this occurs, turn off flash and remove the batter-
ies, then reinstall batteries and turn the power on. This
should properly reset the computer.
2
Slide the meter/feet lever (small
switch in the mouth of the cham-
ber) to select desired indication (m or
ft.); this will appear in the LCD panel
while the speedlight is in use.
The lever is preset to meters (m) when
shipped from the factory.
Installing Batteries
3
Load four 1.5V AA-type penlight
alkaline-manganese or 1.2V NiCd
batteries into the battery chamber. Be
sure to follow the indication
inside the chamber to ensure the bat-
teries are properly loaded.
Using an external power source
For an external power source, use optional Nikon DC
Unit SD-7 or SD-8. For battery information, see page
138.
