is 100% charged to the chosen power level.To change the ready signal mode, hold down or
push repeatedly the

Ready Signal Button

[17] until the desired function is visible at the

Ready Signal Indicators

[16]:

BEEP – a short acoustic signal indicates that the generator is fully charged.

BUZZ – an intermitting signal is audible while the generator is charging.

BEEP & DIM – the modelling light is dimmed while charging and a short acoustic signal
indicates that the generator is fully charged.

BUZZ & DIM – an intermitting signal is audible and the modelling light is dimmed
while charging.

DIM – the modelling light is dimmed while charging.

After 5. the functions return to 1.

PLEASE NOTE!

To guard against wrong exposures, it is not possible to release a

flash while the generator is charging. If you try, a long beep will indicate that no
flash was released.

Photo/IR-Cell

If the

Photo/IR-Cell On/Off Button

[6] lights up, the built-in

Photocell

[5] will sense other

flashes as well as IR-signals from most IR-transmitters. Activate or deactivate the photocell
by pushing the

Photo/IR-Cell On/Off Button

[6].

Auxiliary Functions

The D4 series offers advanced functions like “Interval” for stroboscopic effects, “Sequence”
for multi exposures or multi pops to increase the flash output, and “Delay” to create wipe
effects or for pictures of fast moving objects made with an electronic release system.

set the interval time now visible in the

Power Display

[10] from 0.1-60s. by turning the

Power Dial

[13] for outlet A. If you press down the dial while rotating, the interval time

changes in bigger steps.

PLEASE NOTE!

The interval function can be activated only if you also use the

sequence function. If the generator can’t deliver the desired interval because of
a longer recharging time, it will release the flashes as fast as possible and an
long beep will indicate the improper use.

B – “S” for Sequence

Activate this function by pushing the corresponding

Flash and Modelling Light Button

[12]

and set the sequence now visible in the

Power Display

[10] from 2-60 flashes by turning

the

Power Dial

[13] for outlet B. If you press down the dial while rotating, the sequence

changes in bigger steps.

C – “d” for Delay

Activate this function by pushing the corresponding

Flash and Modelling Light Button

[12]

and set the delay time now visible in the

Power Display

[10] from 0.01-60s. by turning the

Power Dial

[13] for outlet C. If you press down the dial while rotating, the delay time

changes in bigger steps.

PLEASE NOTE!

Always check the optimal delay time by taking test exposures:

All cameras have a different release delay and the effect depends on the speed
and moving direction of the subject. The following list is a rough basis for your
own tests to create wipe effects:
