2. Preparing the flash unit for use

2.1 Mounting the flash unit

2.1.1 Mounting the flash unit on the camera

Turn off the camera and the flash unit by their main switch!
•
Turn the knurled nut against the flash unit’s housing until the stop point is reached.
The locking pin in the adapter shoe is now fully retracted into the case.
• Slide the flash unit’s foot completely into the camera’s accessory shoe.
• Turn the knurled nut against the camera body as far as possible, thereby
clamping the flash unit. If the camera does not have a locking hole the
spring-loaded locking pin retracts into the adapter case so that it does not
damage the surface.

2.1.2 Removing the flash unit from the camera

Turn off the camera and the flash unit by their main switch!
• Turn the knurled nut against the flash unit’s housing until the stop point is
reached.
• Withdraw the flash unit from the camera’s accessory shoe.

2.2 Power supply

2.2.1 Suitable batteries

The flash unit can be operated with any of the following batteries:
• 4 NiCad batteries1.2 V, type IEC KR 15/51 (KR6, size AA). They permit
very fast recycling and are economical in use because they are recharge-
able.
• 4 nickel-metal-hydride batteries 1.2 V, type HR6 (size AA). They have a
significantly higher capacity than NiCad batteries and are less harmful to
the environment (no cadmium).
• 4 alkaline-manganese dry-cell batteries 1.5 V, type IEC LR6 (size AA).
Maintenance-free power source for moderate power requirements.
• 4 lithium batteries 1.5 V, type IEC FR6 L91 (size AA). Maintenance-free
high-capacity power source with a low self-discharge rate.

Remove the batteries from the flash unit if it is not going to be used
for an extended period of time.

2.2.2 Replacing batteries (Fig. 1)

The batteries are exhausted if the recycling time (elapsing from the triggering
of a full-power flash, e.g. in the M mode, to the moment the flash ready indi-
cator lights up again) exceeds 60 seconds.
• Turn off the flash unit by its main switch.
• Slide the battery compartment cover in the direction of the arrow and fold
open.
• Insert the batteries lengthwise in conformity with the indicated battery sym-
bols and close the battery compartment cover.
When loading batteries ensure correct polarity, as indicated by the
symbols in the battery compartment. Mixed up battery poles may
destroy the flash unit!
Replace all batteries at a time and make sure that the batteries are of
the same brand and type and have the same capacity!
Exhausted batteries must not be thrown in the dustbin! Help protect
the environment and dispose of exhausted batteries at the appro-
priate collecting points.

2.3 Switching the flash unit on and off

The flash unit is switched on with the main switch on top of the battery com-
partment cover. In the upper „ON“ position, the flash unit is on.
To turn off the flash unit push the main switch down to its bottom position.
If your flash unit is not going to be used for an extended period of
time, we recommend to switch it off with the main switch and to
remove the power sources (batteries).
