ABOUT THE BATTERY
This flash unit uses four “AA” type Alkaline dry cell batteries or Ni-Cad, Ni-MH,
rechargeable batteries. Manganese batteries can also be used but as they have a
shorter life than Alkaline batteries, we do not recommend using them. Please replace
batteries if it takes more than 30seconds to light the Ready Lamp.
■
To assure proper electrical contact, clean the battery terminals before installing the
batteries
■
NiCad batteries do not have standardized contacts. If you use NiCad batteries,
please confirm that the battery contacts touch the battery compartment properly.
■
To prevent battery explosion, leakage or overheating, use four new AA batteries of
the same type and brand. Do not mix the type or new and used batteries.
■
Do not disassemble or short-circuit batteries, or expose them fire or water; they
may explode. Also, do not recharge the batteries other than Ni-Cd rechargeable
batteries.
■
When the flash will not be used for an extended period of time, remove the
batteries from the flash, to avoid the possibility of damage from leakage.
■
Battery performance decreases at low temperatures. Keep batteries insulated when
using the flash in cold weather.
■
As with any flash, it is recommended you carry spare batteries when on a long trip,
or when photographing outdoors in cold weather.
BATTERY LOADING
1. Be sure to set the Power Switch to the off position then slide, the battery cover in
the direction of the arrow to open (fig.2).
2. Insert four AA size batteries into the battery chamber. Be sure the + and – ends of
the batteries are aligned according to the diagram in the chamber (fig.3).
3. Close the cover.
4. Slide the Power Switch to the ON position. After few seconds, the Ready Lamp will
light, indicating that the flash unit can be fired.
5. Please press the “Test Button” to be sure that the flash is working properly.
■
If the battery power is not sufficient, or if there is an electronic information error, the
flash coverage angle indicator will blink to indicate the condition.
ATTACHING AND REMOVING THE FLASH TO AND FROM THE
CAMERA
Be sure turn off the Power Switch. Then insert the Shoe Base into the hot shoe on the
camera and turn the Shoe Locking Ring until it is tight (fig.4)(fig.5).
■
When you attach or remove the flash, grasp the bottom of the flash to prevent
damage to the shoe foot and camera’s hot shoe.
■

the flash unit.
■
To remove the flash, rotate the shoe-locking ring in the opposite direction of
◄
LOCK mark, until it stops.
TTL AUTO FLASH
In the TTL AUTO Mode, the camera will control the amount of flash lighting to get the
appropriate exposure for the subject.
Depending on the combination of the camera, lens, exposure mode and metering
mode, the TTL system may change. Please refer to Chart.
■
When you use Digital SLR cameras, functions will vary depending on the lens type
and combinations of exposure modes, same as F5 and F100 group. (However, all
TTL exposure functions will be the D-TTL (i-TTL) system).

1. Set the exposure mode of the camera. (However, depending on the camera,
exposure setting may vary). Please refer to Camera’s Instruction manual.
2. Slide the Power Switch to the TTL Position.
■
If the flash coverage angle indicator blinks when you turn on the power of your flash,
please make sure that the flash head bounce angle is adjusted to the normal (0
˚
)
position.
3. Focus onto the subject.
4. Press the shutter button after the flash is charged.
■
If the Ready Lamp blinks, the flash power is not sufficient for that situation. Please
retake the picture at a distance closer to the subject.
■
If you use the AF camera with AF lens, the AF Auxiliary Light will turn on automatically as
you focus on a subject in a dark area. However the AF Auxiliary Light will not light up if
central focus area is not selected. Note: Effective distance is up to about 0.7 to 9 meter
(2.3-29.5 feet).
■
When the flash is fully charged, the flash mark will appear in the finder. If the
shutter is released before the flash is fully charged, the camera will take the picture
at a slow shutter speed, with no flash.
■
To conserve battery power, the flash unit automatically turns itself off when the flash
is not used within approximately 80seconds. To turn the flash on again, depress the
“TEST” button or the camera shutter button, halfway.
■
In case of the combination with
◎
on the above chart, the flash coverage angle
will be set automatically, according to focal length of the attached lens. In case of
attaching the AF zoom lens, the flash coverage angle will be changed according to
lens zoom setting. In case of other combinations, the flash coverage angle will be
set to 24mm.
■
Please refer to
《
chart.1
》
for the effective distance ranges (ISO100).
MANUAL FLASH OPERATION
This flash unit can be used in Manual Mode at full power and at 1/16 power.
1. Set the camera’s exposure mode to Manual / M mode.
2. Slide the flash unit’s Power Switch to MH (full flash power) or to ML (1/16 flash
power).
3. Focus on the subject and set the camera’s F-stop, using the exposure calculated by
the formula shown below:
F-stop = Guide Number (G.N.)
÷
Flash to Subject Distance (m)
4. After the flash is fully charged, press he Shutter Release button to take the picture.
Guide Number will change according to the Zoom Head position, (see
《
chart.2
》
). Guide
Number will also change according to film speed (ISO),(see
《
chart.3
》
). In the case of
non-ISO100 speed films, multiply the
《
chart.3
》
number by the
《
chart.2
》
number. For
example, using ISO200 film, Zoom Head position for 24mm and the MH mode;
multiply the
《
chart.3
》
number ”1.4” by the
《
chart.2
》
number “34.0”: 34.0
×
1.4=47.6. This
will be the new effective Guide Number (G.N.) in meters. To determine the G.N. in feet,
multiply the G.N. in meters by 3.3.
EX
. If flash to subject distance is 8.5 meters:
F-stop = 47.6
÷
8.5 = 5.6
(5.6 is the F-stop to set on the camera.)
When repeatedly using the flash rapidly in the MH mode, it should be allowed to “rest”
for about 10 minutes after each 20 flashes. If used under the same conditions in the
ML mode, the flash should be allowed to “rest” after each 40 flashes.
WIDE PANEL
This flashgun is equipped with a built-in wide panel, which can provide an ultra wide
17mm angle of coverage. Slide out the wide panel and catch light panel and flip it
down to cover the flash’s head (fig.6-1). (Be careful to slide the panels out smoothly.)
Then put the catch light panel back in its place (fig.6-2). The coverage angle setting of
the flash will be set to 17mm automatically.
■
The flash coverage angle indicator will show that the wide panel is in use by
blinking the both end values (24mm and 105mm) slowly (1sec each time).
■
If the built-in wide panel comes off accidentally, adjustment mechanism of flash
coverage angle will not function. In this case please contact the store where you
