5. Controls and displays
• Push the main switch ቪ into the upper ON position and then switch on the
flash unit.
The adjusted flash mode is indicated on the display window. The flash rea-
diness indicator ቩ lights up when the flash unit is ready for operation. The
flash unit is switched off when the main switch is in the lower position.
• The secondary reflector ባ can be switched on with the switch for the
secondary reflector, for instance for frontal fill-in when bouncing the flash.
Push the switch ቮ into the top position. When in the middle position the
secondary reflector will only emit approx. 50% of its light intensity. The
secondary reflector is turned off when the switch is in the bottom position.
• Set the ISO value of the camera or loaded film with the setting button for
ISO sensitivity ቱ.
• Select the flash mode with the setting disk on the flash head. Adjust the set-
ting mark for aperture pre-selection ተ to the required auto working aper-
ture, TTL mode or M manual mode, or a manual partial light output.
• A flash can be fired with the manual firing button ቨ when flash readiness
is established. A full-power flash is fired in TTL and M mode. When in
automatic flash mode or with manual partial light output the flash fired
depends on the adjusted parameters (ISO / aperture / partial light output).
• The flash readiness indicator ቩ lights up when the flash capacitor has
become charged so that flashes can be fired. When an SCA adapter is
being used the camera will automatically switch over to flash synch speed
should this be necessary.
• The correct exposure indicator ቫ lights up for approx. 3 sec. if the shot
was correctly exposed in TTL or automatic flash mode. When an SCA
adapter is used a corresponding indication is given in the camera’s view-
finder or on the camera display, depending on the camera type.
• Further flash modes can be set for operation with a suitable system camera
and an adapter from the SCA 3002 system (see Operating Instructions for
the given camera and SCA adapter). The setting is made with the “Mode”
key ቭ. The adjusted flash mode is indicated on the indicator window.
6. Flash modes
6.1 Automatic flash mode
In the automatic flash mode A the sensor ባ measures the light reflected by
the subject. The flashlight is turned off by the flash unit’s electronic circuit
when the amount of light is adequate for the given exposure.
Setting procedure
• Set the ISO value of the camera or loaded film with the setting button ቱ on
the flash head.
• Adjust the setting mark for aperture pre-selection ተ on the flash head to
the camera’s f-stop. “A” lights up on the indicator window of the flash unit.
The maximum flash range can be read off the setting mark of the selector
disk. The shortest shooting distance is approx. 10% of the maximum flash
range. The subject should be located in the middle third of the indicated ran-
ge to give the electronic circuit leeway for compensation.
We recommend the camera mode aperture priority (A, Av) or manual
(M).
Automatic setting of the ISO value and aperture
The aperture and ISO sensitivity of the camera can be automatically set on
the flash unit when the latter is operated with an adapter from the SCA 3002
system:
The automatic setting range for ISO extends from ISO 6 to ISO 6400.
The automatic setting range for the aperature extends from f/1.0 to
f/45 (at ISO 100 / 21°), including all the in-between values.
• Equip the flash unit with the connecting cable SCA 3045 and appropriate
adapter from the SCA 3002 system and connect to the camera.
• On the flash unit, set any auto working aperture with the setting mark for
aperture pre-selection ተ.
• Switch on the flash unit and the camera.
• Lightly touch the camera’s shutter release so that data can be exchanged
between the camera and the flash unit.
