OP (Option) switch ———————————————————
When the power switch is set to the “OP” position as shown in photo 6, the focusing
lamps built into the four corners of the light emitting section light continuously. This
light can be used as AF auxiliary lighting under low light or as auxiliary lighting
when a strobe light would be too strong to use.
Lighting of Ready Lamp
f The flash is ready to fire as soon as the Ready lamp lights. However, if full-power
firing is attempted immediately after the Ready lamp lights, the f-value will be
one step darker than the specified guide number. To obtain full power, wait about
5 to 10 seconds after the Ready lamp lights.
f When using the unit in the Multi-firing mode, be sure to use brand-new batteries
so that they can be recharged fully.
f If it takes more than 30 seconds for the Ready lamp to come back on after the
flash is fired at full power, it is likely that the batteries are exhausted. Replace
them with new ones.
Focusing Lamps
The unit has four focusing lamps to support focusing.
When the LAMP button on the power supply section or
on the back of the light emitting section is pressed (both
buttons are shown in photo on right), the focusing lamps
light for about 30 seconds, then turn off again. However,
if the fl ash is emitted within 30 seconds, the focusing
lamps automatically turn off immediately before fi ring.
The focusing lamps can also be turned off by pressing
the LAMP button again. The focusing lamps are
designed for use under low light when the AF might have
diffi culty obtaining focus, but they can also be used to
shoot pictures using their light alone. In the latter case,
do not press the LAMP button but set the power switch
to the “OP” position. The lamps will remain on as long as
the power switch is in this position.
When turning out focus lamps,

Shooting in A (Auto EV Control) Mode
After the unit is installed on the camera, press the
MODE button to select “A” to put the unit in the Auto
EV control mode. This mode can be used with TTLcompatible cameras as well as other cameras.
ᱺ First set the shooting sensitivity (ISO speed) of the
strobe. Press the MODE button repeatedly until “ISO”
blinks, then turn the rotary dial to select the desired ISO
value, and press the MODE button again. Now the setup
of the ISO speed of the strobe is complete.
ᱻ Press the MODE button again until “A” is displayed
and press the SEL (Select) button so that “F” blinks. Then, turn the rotary dial to
select the exposure value matching the purpose of shooting. This unit can fi ne
adjust the exposure values between 2 and 16 in 19 steps.
ᱼ Apply the exposure value set above to the camera lens. Now the system is ready
for shooting in the Auto mode.
Setting Example —————————————————————————
When the sensitivity is set to “ISO
100,” the exposure can be adjusted
in 19 steps between F2 and F16. For
reference, the EV control range at
each f-value is shown by the bar graph
in the interlocked range indicator. For
example, when the display is as shown
on the right, the EV control range at F4
is from 0.5 to 4 meters (1.5 to 13 ft).
When deciding the f-value, it is
recommended to open the aperture (set a smaller value) when shooting a distant
object and to stop it down (set a larger value) when shooting a closer object. When
you need to increase the depth of fi eld, select the minimum f-value in the EV control
range. The bar graph shows the working range of the Auto mode between 0.5 and
16 meters (1.6 and 52 ft). When the range is larger or smaller than the limit, “_” or “`”
is displayed respectively.
• In close-up shooting, the brightness may vary depending on the condition of
the lens (such as the zoom projection length). In such a case, adjust the f-value
accordingly.

Shooting in M (Manual) Mode
This unit is capable of manual mode shooting in 25
steps from full power (1/1) to 1/256 power (in 1/3 EV
steps). In the following cases, press the MODE button
until “M” is displayed to make full use of the effects
of the Manual mode. For Manual mode setup, see
“Setups” on page 8. The Manual mode setups are
held in memory even after the power switch is set
to OFF then ON again, so that you can use the unit
without additional setup as far as you use the Manual
mode.
The Manual mode is effective in following cases.
When daylight sync flashing (in outdoor shooting under sunlight, the strobe light
can be used as an auxiliary light to minimize shadows on the subject formed by
the sun) or shooting against backlight is required.
When you want to take several pictures by varying the f-values.
When you want to use motor drive or auto winder.
When you want to increase the number of flashes.
⁴ This indicates the shooting range displayed on the LCD panel. “`” is displayed
when the maximum distance of 16 meters (52 ft) is exceeded. “`” is displayed
when the minimum distance of 0.25 meter (0.8 ft) is exceeded.

Setup Example ——————————————————————————
Press the MODE button again until “M”
is displayed and press the SEL button
until the “PR (Power Ratio)” value
blinks. Then, turn the rotary dial to
select the desired exposure value and
press the SEL button again. Now the
PR value setup is complete.
Press the SEL button again so that
the “F (f-value)” blinks. Then, turn the
rotary dial to select the exposure value while checking the bar graph on the range
indicator below. The reference shooting range is either the distance indicated on
the camera lens or the actual subject distance measured visually.
When the display is as shown above, for example, the ISO speed is set to 100, the
PR value is 1/4, the f-value is F4.0 and the fl ash fi res with the optimum power on the
subject located at about 2 meters (6.6 ft).
The value shown by the bar graph on the range indicator is
merely a reference value, and the actual value is variable
IMPORTANT
depending on the brightness of the subject and conditions
of the lens. For optimum shooting, it is recommended to
perform test shooting before determining the PR value.

Shooting in MULT (Multi-firing) Mode
When the MODE button is set to “MULT,” the fl ash
enters the Multi-fi ring mode, in which a continuous
motion can be captured in a single picture just
like a stop-motion picture. The fi ring frequency
(number of fl ashes per second, expressed in Hz)
can be selected between 1 and 90 Hz. To set the
frequency, press the SEL button so that “Hz” blinks
and turn the rotary dial to select the desired value.
After this, press the SEL button so that the “Flash”
value blinks and then set the number of fl ashes.
The number of successive fl ashes can basically be selected between 2 and 99 but
it depends on the fi ring power and frequency. See the table on the right for details.
Other operations in this mode are identical to the Manual mode.
