Using i-TTL Autoflash in the Shooting Modes---------------------------05
To avoid overheating and degrading the flash head, do not
fire more than 20 continuous flashes. After 20 continuous
flashes, allow a rest time of at least 10 min.
If you fire more than 20 continuous flashes and then fire
more flashes in short intervals, the inner overheating
prevention function may be activated to make the recycling
time about 8 to 20 sec. If this occurs, allow a rest time of
about 15 min, and the flash will then return to normal.
Cautions for firing continuous flashes
●
●
Installing the Batteries
Install four size-AA batteries.
1
● Use your thumb to press the
battery compartment cover, and
then slide it to open the cover.
. Open the cover.
2. Install the batteries.
● Make sure the + and – battery
contacts are properly oriented
as shown in the compartment.
3. Close the cover.
● Slide the battery compartment
cover as shown by the arrow to
close it.
Recycling Time and Flash Count (with size-AA alkaline batteries)
Recycling Time
Approx. 0.1-5 sec
Flash Count
Approx. 100-700
Based on new size-AA alkaline batteries.
● Use a new set of four batteries of the same brand. When
replacing the batteries, replace all four at one time.
● Size-AA Ni-MH or lithium batteries can also be used.
Getting Started and Basic Operation
03 04
If < > blinks on the LCD panel, the
battery power is low and the camera
flash stops charging. In this case, the
<ZOOM> button is disabled. Please
change the batteries immediately.
● Using size-AA batteries other than the alkaline type may cause
improper battery contact due to the irregular shape of the battery
contacts.
● If you change the batteries after firing many flashes continuously,
be aware that the batteries might be hot.
When the Power Switch is set to ON and the flash power is off
automatically after a certain period of idle use, power
consumption exists and long-time power discharge damages
batteries. Therefore, make sure to shut down the flash power by
setting the Power Switch to OFF if the flash is not used for long.

2. Focus the subject.
• Press the shutter button
halfway to focus.
• The shutter speed and
aperture will be displayed in
the viewfinder.
• Check that the < > icon is
lit in the viewfinder.

3. Take the picture.
• Check that the subject is
within the effective range
displayed on the LCD panel.
• Right before the shot is
taken, a preflash is fired, and
then the main flash is fired.
• <TTL> will be displayed on the LCD panel even if the camera is
compatible with i-TTL.
Using i-TTL Autoflash in the Shooting Modes
Just set the camera’s shooting mode to <A> (aperture-priority AE),
<S> (shutter-priority AE), or <M> (manual) and you can use i-TTL
autoflash.
Select this mode when you want to set the shutter speed
manually.
The camera will then automatically set the aperture
matching the shutter speed to obtain a standard exposure.
• If the aperture display blinks, it means that the
background exposure will be underexposed or
overexposed. Adjust the shutter speed until the aperture
display stops blinking.
Select this mode when you want to set the aperture
manually.
The camera will then automatically set the shutter speed
matching the aperture to obtain a standard exposure.
If the background is dark like a night scene, a slow sync
speed will be used to obtain a standard exposure of both
the main subject and background.
Standard exposure of the main subject is obtained with
the flash, while a standard exposure of the background is
obtained with a slow shutter speed.
• Since a slow shutter speed will be used for low-light
scenes, using a tripod is recommended.
• If the shutter speed displays blinks, it means that the
background exposure will be underexposed or
overexposed. Adjust the aperture until the shutter speed
display stops blinking.
Select this mode if you want to set both the shutter speed
and aperture manually.
Standard exposure of the main subject is obtained with
the flash. The exposure of the background is obtained
with the shutter speed and aperture combination you set.

Bounce Flash
By pointing the flash head toward a wall or ceiling, the flash will
bounce off the surface before illuminating the subject. This can
soften shadows behind the subject for a more natural-looking shot.
This is called bounce flash.
Set the Bounce Direction
Hold the flash head and turn it to a satisfying angle.
1. Point the flash head upward
by 90°.
2. Pull out the wide panel.
• The catchlight panel will come
out at the same time.
3. Push the wide panel back in.
• Push in only the wide panel.
• Follow the same procedures
as for bounce flash.
• Point the flash head straight ahead and then upward by 90°.
The catchlight will not appear if you swing the flash head left or
right.
• For maximum catchlight effect, stay 1.5m/4.9ft away from the
subject.
ZOOM: Setting the Flash Coverage and Using the Wide Panel
The flash coverage can be set to match the lens focal length from
24 mm to 105mm. The flash coverage can be set automatically or
manually. Also, with the built-in wide panel, the flash coverage can
be expanded for 14mm wide-angle lenses.

flash screen regardless of practical shutter speed.
• With high-speed sync, the faster the shutter speed, the shorter
the effective flash range.
• To return to normal flash, set the flash sync speed to other
options other than Auto FP. Then the icon < > will disappear
when pressing the shutter halfway.
• Multi flash mode cannot be set in high-speed sync mode.
• Over-temperature protection may be activated after 15
consecutive high-speed sync flashes.
1. Focus the subject.
2. Press the <FV> button.
• Aim the subject at the center of
the viewfinder and press <FV>
button.
• The camera flash will fire a
preflash and the required flash
output for the subject is retained
in memory.
• Each time you press the <FV> button, a preflash will be fired and
a new flash exposure setting will be locked. The FV lock icon
< > will be displayed in the viewfinder.
• If <TTL> is not displayed on the LCD panel, FV lock cannot be
set.
• If the subject is too small, FV lock might not be very effective.
• <FV> button is on the camera. The <FV> button position may
vary based on different Nikon camera models. Please refer to the
instruction manuals of your Nikon camera model.
High-speed Sync
With high-speed sync (FP flash), the flash can synchronize with all
shutter speeds. This is convenient when you want to use aperture
priority for fill-flash portraits.
• If the wall or ceiling is too far away, the bounced flash might be
too weak and result in underexposure.
• The wall or ceiling should be a plain, white color for high
reflectance. If the bounce surface is not white, a color cast may
appear in the picture.
Creating a Catchlight
With the catchlight panel, you can create a catchlight in the
subject’s eyes to add life to the facial expression.

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 / Firing 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 sec.
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 min. If you try
to use the stroboscopic flash mode more than 10 times in
succession, the firing might stop automatically to protect the flash
head. If this happens, allow the camera flash to rest for at least
15 min.
• Stroboscopic flash is most effective with a highly reflective
subject against a dark background.
• Using a tripod, a remote switch, and external power source is
recommended.
• A flash output of 1/1 or 1/2 cannot be set for stroboscopic flash.
• Stroboscopic flash can be used with "buLb".

• If you set the flash coverage manually, make sure it covers the
lens focal length so that the picture will not have a dark
periphery.
• If you use a commercially-available sync cord to connect the
camera to the camera flash' PC terminal, set the flash zoom
manually.
Using the Wide Panel
Pull out the wide panel and place
it over the flash head as shown.
The flash coverage will then be
extended to 14 mm.
• The catchlight panel will come

• S1 or S2 mode is not supported in the following cases: when
“red-eye reduction” function is started by the master flash (either
camera pop-up flash or external on-camera flash); and when the
master flash uses the modeling flash function.
• In S1 or S2 mode, the flash output level is only manually
adjustable.
• In S1 or S2 mode, TTL flash or Multi flash is not available.
• Setting as S1/S2 slave triggering mode and attaching to the
camera, the flash will change to master mode and be set as TTL
mode automatically when pressing the shutter button halfway.
creating multiple lighting effects. It is respectively applicable to
manual flash environment. In S1 mode, the flash unit will fire
synchronously when the master flash fires, the same effect as that
by the use of radio triggers.
S2 Slave Triggering Mode
This mode is also called “Preflash Cancel”, similar to S1 mode. In
this mode, the flash unit will ignore a single “preflash” from the
master flash and will only fire in response to the second, actual
flash from the master. Therefore, this flash unit is applicable when
using a TTL master flash.

Protection Function
1.Over-Temperature Protection
• To avoid overheating and deteriorating the flash head, do not fire
more than 20 continuous flashes in fast succession at 1/1 full
power. After 20 continuous flashes, allow a rest time of at least 10
minutes.
• If you fire more than 20 continuous flashes and then fire more
flashes in short intervals, the inner over-temperature protection
function may be activated and make the recycling time about 10
to 15 seconds. If this occurs, allow a rest time of about 10
minutes, and the flash unit will then return to normal.
2.Other Protections
• The system provides real-time protection to secure the device and
your safety. The following lists prompts for your reference:
