1flash exposure compensation
amount will be highlighted on
the LCD panel.
Set the flash exposure compensation
2amount.
● Turn the Select Dial to set the
amount.
● “0.3”means 1/3 step, “0.7”means 2/3
step.
● To cancel the flash exposure
compensation, set the amount to
“+0”.
Press < SET > button again
3to confirm the setting.
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.
Please use XPro or X1 series
2transmitter.
Press High Speed Sync Button
1so that < > is displayed.
● If you set a shutter speed that is the same as or slower than the camera’s maximum flash sync speed, < >
will not be displayed in the viewfinder.
● With high-speed sync, the faster the shutter speed, the shorter the effective flash range.
● To return to normal flash, press < > button again. Then < > will disappear.
● Multi flash mode cannot be set in high-speed sync mode.
● Over-temperature protection may be activated after 50 consecutive high-speed sync flashes.

With stroboscopic flash, a rapid series of flashes is fired. It can be used to capture a 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.
Press <MODE> button so that
1<MULTI> is displayed.
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 flash.
● Stroboscopic flash is most effective with a highly reflective subject against a dark background.
● Using a tripod and a remote control is recommended.
● A flash output of 1/1 and 1/2 cannot be set for stroboscopic flash.
● Stroboscopic flash can be used with“buLb”.
● 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.

1. Over-Temperature Protection
● To avoid overheating and deteriorating the flash head, do not fire more than 75 continuous flashes in fast
succession at 1/1 full power. After 75 continuous flashes, allow a rest time of at least 5 minutes.
● If you fire more than 75 continuous flashes and then fire more flashes in short intervals, the inner over-
temperature protection function may be activated and make the recycling time over 10 seconds. If this occurs,
allow a rest time of about 5 minutes, and the flash unit will then return to normal.
● When the over-temperature protection is started, is shown on the LCD display.

Modeling Lamp
AD400Pro is equipped with a 30W LED modeling lamp which has two continuous lighting modes.
• There are three modes: OFF, Percentage and PROP. Short press the Modeling Lamp Button, and the
three mode will be displayed on the LCD panel in sequence:
1. OFF: the modeling lamp is off.
2. Percentage: 10%~100%(to prevent overheat, <30% the fan rotates in low speed while >30% in high speed).
3. PROP: The modeling lamp's power changes with the flash's power. The bigger power the flash has, the
brighter the modeling lamp is(to prevent overheat, <1/64 the fan rotates in low speed while >1/64 in high
speed).
• Long press the modeling lamp for 2 seconds to adjust the percentage of modeling lamp from 10% to
100%.
Sync Triggering
The Sync Cord Jack is a Φ3.5mm plug. Insert a trigger plug here and the flash will be fired synchronously with the
camera shutter.
