1) Optional extra
Be sure to switch off the flash unit by its main switch prior to mounting
or removing the connecting components! Before mounting or removing
the flash unit, switch off both the camera and the flash unit!
Mounting the flash unit:
• Push the SCA adapter or standard foot 301 into the camera’s accessory
shoe and lock in place with the knurled nut.
• Fasten the camera bracket with the bracket screw to the camera’s tripod
socket. For medium- and large-format cameras we recommend the use of
the 70-35 bracket (optional extra).
• Insert the camera bracket into the mount of the bracket holder until it
is audibly engaged.
• Secure the camera bracket with the locking screw.
• Connect the synch or connecting cable to the flash unit and camera or
adapter.
4. Power supply
The flash unit can be operated with:
• 6 alkaline manganese batteries IEC LR 6 (AA-type) in the battery holder
45-39 (optional extra), or
• Metz NiMh battery pack 45-56, or
• Power Pack P 50 / P76 (optional extra)
☞
Do not use lithium cells! Their higher voltage would damage the flash
unit’s electronic system. Only use the permitted power sources (see
above). Warranty claims for faults and damage to the flash unit arenot
accepted if they were caused by the use of accessories from other
manufacturers.
Battery replacement
Press the two locking keys of the battery holder (optional extra) and pull the
holder out of the flash unit (Fig 4a). To return the battery holder insert it into
the flash unit’s handle-mount grip and press it until it audibly locks in place.
Exchanging the batteries
Press together the two smooth locking keys of the dismantled battery holder
(optional extra) and remove the lid (Fig. 4b). Insert new batteries in confor-
mity with the polarity symbols indicated on the bottom of the holder. Return
the lid and lock in again.
Mixed up battery poles may destroy the flash unit.. Replace all batte-
ries at a time and make sure that the batteries are of the same brand
and type and have the same capacity! Spent batteries must not be
thrown into the domestic waste! Help keep the environment clean and
discard spent batteries at corresponding collecting points.

4.1 Operation with NiMh Battery Pack 45-56

4.1.1 Battery notes

• The battery pack must be charged before it is used for the first time.
• The battery pack reaches its maximum capacity only after several char-
ge/discharge cycles.
• Avoid deep-discharging of the battery pack. Never attempt to fully dischar-
ge the battery pack (with a lamp or similar load). Deep-discharging may
destroy the battery pack.
• Rechargeable batteries discharge themselves gradually even if they are not
used. The self-discharge rate increases at higher ambient temperatures.
We therefore recommend that you store the battery pack at a temperature
