1. Set the camera’s exposure mode to M.
2. Press the MODE button on the flash unit to select M.
3. The guide number value blinks when you press the SEL button.
4. Press 㸠 or 㸢 button to set the desired flash power output.
5. The manual flash output display will stop blinking and remain
displayed after you press the SEL button again.
6. Adjust the focusing by pressing the shutter button, read-out subject
distance from the focus ring on the lens. Then, adjust the F-stop or
flash power, until the distance indicated on the LCD panel of the
flash, and subject distance becomes about equal.
7. When the Ready Light of the flash is illuminated, the unit is ready for use.
ۋ You can calculate the correct exposure by using the following formula:
Guide Number “GN” / Flash to Subject Distance = F-stop
This flash unit will automatically calculate and indicate the appropriate Subject Distance according to the
above formula.(Please refer to table1 on the last page)
SECOND CURTAIN SYNCHRONIZATION
When you photograph a moving subject with slow synchronization, usually the furrow of the subject will be
exposed in front of the subject. The ordinary flash light will fire when the first shutter curtain is fully opened, thus
the subject will be exposed from the time flash is fired to the time the shutter is closed (First curtain
synchronization). When you use second curtain synchronization, the flash will fire just before the second curtain
begins to closes, and the subject will be exposed by ambient light from the time the shutter opens until the flash
fires. As a result the furrow of the subject will be recorded behind the subject. It will be a more natural effect.
ۋ This mode cannot be used with EOS 700, 750, 850 cameras.
1. Set the desired picture-taking mode of the camera
2. Press 㸠 or 㸢, button mark will be displayed on the LCD panel.
3. Adjust the focus, and take the picture after confirming the ready light.
ۋ First curtain synchronization will be set, if
mark is not
displayed.
ۋ
If the camera is set to Full Auto Mode this function cannot be used.

To cancel second –curtain synchronization, turn off the mark on the LCD panel by using 㸠 or 㸢 buttons.
HIGH SPEED SYNC (FP) FLASH, A TYPE CAMERAS ONLY
When you take a picture with an ordinary flash, you cannot use a shutter speed faster than the camera’s
synchronized speed, because the flash must fire when the shutter curtain is fully open. The High Speed
Sync keeps firing while the shutter curtain is running. Thus you can use a shutter speed faster than the
shutter’s normal synchronized speed.
1. Select the camera’s exposure mode. (“Tv” or “M” modes can be used)
2. Select a shutter speed faster than the camera’s normal synchronized speed.
3. Slide the Power Switch of the flash to the ON position.
4. Choose the Flash Mode by using MODE button (“ETTL” or “M” modes can be used).
5. Press 㸠 or 㸢 button until the mark is displayed on the LCD
panel.
6. Focus on the subject
7. Check that the subject is located within the effective distance,
indicated on the LCD panel.
8. Confirm the mark in the viewfinder of the camera, and then
you can take the picture.
ۋ
With high-speed sync, the Guide Number changes depending on the shutter speed. The flash range will be
shorter (ie Guide Number will be smaller) when shutter speed is faster. (Please refer to table2 on the last page).
ۋ Selecting shutter speeds slower than the camera’s normal synchronized speed cancels Hi-speed sync.
Then the flash will automatically set to normal ETTL operation. To activate FP flash again, follow the
procedure (No.1) for High speed sync (FP flash) described in this instruction manual.
ۋ It is possible to use exposure compensation function, with high speed synchronization operation. To do
