2.3 Battery replacement

Press the two locking keys of the battery housing, and pull out of the flashgun
(fig. 4a). To return the battery housing press the two locking keys together
and press into the handle-mount grip of the flashgun until it audibly engages.

2.3.1 Exchanging the batteries

Press together the smooth locking keys of the dismantled battery housing
(only with BAT-version, otherwise optional extra) and remove the lid (fig. 4b).
Insert new batteries in conformity with the polarity symbols indicated in the
base of the housing. Return the lid and lock in again.
Spent batteries must not be thrown into the domestic waste! Help keep
the environment clean and discard spent batteries at corresponding
collecting points!
The battery housing must not be fitted with NiCad batteries! The contacts
of the battery housing are only intended for alkaline manganese batte-
ries. The lower resistance of NiCad batteries means that more current can
k
flow, and this can damage the flashgun. The NiCad Battery Pack 45-40
has special contacts which do not allow the flow of high currents.

2.3.2 Operation with the battery pack

The NiCad battery should be charged for 5 hours before it is used for the first
time. The NiCad battery can be charged within the flashgun or externally.
Warning: The flashgun must NOT be switched on while the battery is
being charged within the flashgun!
The NiCad battery is discharged if the recycle time after a flash exceeds 60
seconds.
Adjust the correct mains voltage on the charger prior to charging. The volta-
ge selector (fig. 5a) is located next to the plug and can be adjusted with a
small screwdriver.
The connection for the charger (fig. 5b) is in the base of the NiCad battery.

The adjoining pilot lamp lights up while charging is in progress.
The charging time for a completely exhausted NiCad battery is 5 hours. A
partly discharged NiCad battery requires a correspondingly diminished
charging time.
• To identify an exhausted battery: Push the knurled slide in the battery lid to
the black mark.
• To identify a charged battery: Push the knurled slide in the battery lid to the
white mark.

2.4 Switching the flashgun on and off

The flashgun is switched on with the main switch
nently switched on when the switch is pushed to the top position, and the
operating light shines. Push the main switch to the bottom position to switch
off the flashgun.

3. TTL Flash Mode

(only with SCA adapter)
Perfect flash exposures can be shot in a simple manner in TTL mode.
The exposure readings in TTL mode are made by the sensor built into the
camera. This sensor measures the light reaching the film through the camera
lens. As soon as the film has been exposed by the correct amount of light, an
electronic control circuit within the camera transmits a stop signal to the
adapter (optional accessory), and the flash is instantly cut out.
The advantage of this flash mode is that all factors influencing the exposure
of the film (filters, change of aperture and focal length with zoom lenses,
extensions for close-ups, etc.) are automatically taken into account.
The TTL flash mode is only possible with cameras that feature this func-
tion. The flashgun must be fitted with a corresponding SCA adapter
(see SCA 3002 System Instructions and SCA Survey Table) for this pur-
pose. A film must be loaded in the camera to test the TTL functions.
Exposure corrections may be necessary with pronounced differences
in contrast, for instance dark objects in snow (see Ch. 11, page 49).
