FLASH MODE: TTL AUTOFLASH
This flash has three flash modes: TTL, Manual (M), and Multi (Stroboscopic). In
TTL mode, the camera and the flash will work together to calculate the correct
exposure for the subject and the background. In this mode, multiple TTL
functions are available: FEC, HSS, second curtain sync, etc.
Press <MODE> Mode Selection Button and three flash modes will display on
the LCD panel one by one with each pressing.
TTL MODE
Press <MODE> Mode Selection Button to enter TTL mode. The LCD panel will
display <TTL>.
• Press the camera release button halfway to focus.
16
• When the shutter button is fully pressed, the flash will fire a preflash that the
camera will use to calculate exposure and flash output the instant before the
photo is taken.
Display “Hi”: When the flash output value is up to the maximum value, “Hi” will
be displayed and blinking for 3 seconds. Adjust the camera’s parameters if
underexposure appears.
Display “Lo”: When the flash output value is up to the minimum value, “Lo” will
be displayed and blinking for 3 seconds. Adjust the camera’s parameters if
overexposure appears.
FEC: FLASH EXPOSURE COMPENSATION
With FEC function, this flash can adjust from -3 to +3 in 1/3rd stops. It is useful
in situations where minor adjusting of the TTL system is needed based on the
environment.

HIGH-SPEED SYNC
High Speed Sync (FP flash) enables the flash to synchronize with all camera
shutter speeds. This is convenient when you want to use aperture priority for
fill-flash portraits.
Choose the < > button:
• Press the <SYNC> button to turn on high-speed sync function.
• Set the Nikon camera high-speed sync to 1/320s (auto FP) or 1/250s (auto FP)
• With high-speed sync, the faster the shutter speed, the shorter the effective
flash range.
• Multi flash mode cannot be set in high-speed sync mode.
• Over-temperature protection may be activated after 15 consecutive
high-speed sync flashes.
• Try to avoid using high-speed sync flash, which will cut short flash tube’s
lifetime.
19
SECOND-CURTAIN SYNC
With a slow shutter speed, you can create a light train following the subject.
The flash fires right before the shutter closes.
• Set Nikon camera to Rear mode.
20
FLASH MODE: MANUAL FLASH
The flash output is adjustable from 1/1 full power to 1/128

In the M mode, high-speed sync and second curtain sync functions can be
achieved.
• Optical S1 Secondary Unit Setting
In M manual flash mode, press the <SLAVE> button so that this flash can
function as an optic S1 secondary flash with optic sensor. With this function,
the flash will fire synchronously when the main flash fires, the same effect as
that by the use of radio triggers. This helps create multiple lighting effects.
• Optical S2 Secondary Unit Setting
Press the <SLAVE> button so that this flash can also function as an optic S2
secondary flash with optic sensor in M manual flash mode. This is useful when
cameras have pre-flash function. With this function, the flash will ignore a single
“preflash” from the main flash and will only fire in response to the second,
actual flash from the main unit.
23
• S1 and S2 optic triggering and off camera high-speed mode are only
available in M manual flash mode.
MULTI STROBOSCOPIC FLASH
With stroboscopic flash mode, a rapid series of flashes is fired. It can be used
to capture multiple images of a moving subject in a single photograph.
You can set the firing frequency (number of flashes per sec. expressed as Hz),
the number of flashes, and the flash output.

25
Calculating the Shutter Speed
During stroboscopic flash, the shutter remains open until the firing stops. Use
the formula below to calculate the shutter speed and set it with the camera.
Number of Flashes/Flash Frequency = Shutter Speed
For example, if the number of flashes is 10 and the firing frequency is 5 Hz, the
shutter speed should be at least 2 seconds.
To avoid overheating and deteriorating the flash head, do not use stroboscopic
flash more than 10 times in succession. After 10 times, allow the camera flash
to rest for at least 15 minutes.
If you try to use the stroboscopic flash more than 10 times in succession, the
firing might stop automatically to protect the flash head. If this happens, allow
at least 15 minutes rest for the camera flash.
26
• Stroboscopic flash is most effective with a highly reflective subject against a
dark background.
• Using a tripod and a remote control is recommended.
• Stroboscopic flash can be used with “bulb mode”.
• If the number of flashes is displayed as “--”, the firing will continue until the
shutter closes or the battery is exhausted. The number of flashes will be limited
as shown by the following table.
