[. . . ] The high energy of the flash light will burn the material or damage the reflector screen if this is not observed. There are no components inside the flashgun that can be repaired by a layman. When taking a series of flash shots at full light output and fast recycling times as provided by NiCad battery operation, make sure To observe an interval of at least 10 minutes after 15 flashes, otherwise the flash unit will be overloaded. The flash unit may only be used in combination with a camera-integrated flash unit if the latter can completely be folded out! [. . . ] They have a significantly higher capacity than NiCad batteries and are less harmful to the environment (no cadmium). Remove the batteries from the flash if the flash unit is not going to be used for an extended period of time. 2 Replacing batteries The batteries are exhausted if the recycling time (elapsing from the triggering of a fullpower flash to the moment the flash ready indicator lights up again) exceeds 60 seconds. Insert the batteries lengthwise in conformity with the indicated battery symbols and close the battery compartment cover. 3 Switching the flash unit on and off The flash unit is switched on and off by its main switch. Switch positions , , M" Manual flash mode with full light output, see Section 6. Replace all batteries at a time and make sure that the batteries are of the same brand and type and have the same capacity!1 Flash readiness indication The flash readiness symbol lights up on the flash when the flash capacitor is charged, theready indicating that flashes can be fired for the next shot. If a picture is shot before flash readiness is signalled then the flash unit will not be triggered. " is not indicated after an exposure, then this means that the picture was underexposed. The shot will then have to be repeated: Set the next smaller f-number (e. 2 Manual flash mode with a given distance · This f-number must be set on the camera or camera lens. 3 Manual flash mode with guide number calculation The aperture to be set on the camera can also be calculated by the following formula: guide number Aperture = -------------------------- flash-to-subject distance The guide numbers for the individual film speeds are listed in the Guide Number Table at the end of the "Technical Data" section. 1 Fill-in flash in daylight The flash can also be used for fill-in flash in daylight in order to eliminate dense shadows and produce a more balanced illumination in contre-jour shots. Ensure that the camera's shutter speed equals or is slower than the camera's flash sync speed (see operating instructions for the given camera). Example: Established aperture = f/8; established shutter speed = 1/60 s Flash sync speed of the camera = 1/100th sec. The two established values for aperture and shutter speed can be set on the camera because the camera's shutter speed is slower than the camera's flash sync speed. To maintain a balanced range of highlights, for instance in order to retain the character of the shadows, the auto aperture selected on the flash unit should be one setting lower than the f-number set on the camera. Not shine directly into the sensor of the flash unit as this would confuse the electronic system and falsify the reading. A dark background that absorbs a great deal of light or, alternatively a light background that reflects a great deal of light (e. Exposure correction in auto flash mode To compensate the above effect the exposure can be corrected by opening or stopping down the camera's aperture. With a predominantly light background the sensor of the flash unit will interrupt the flash prematurely with the result that the subject is underexposed. [. . . ] When turning the reflector vertically, it is essential to ensure that it is moved by a sufficiently wide angle so that direct light can no longer fall on the subject. Consequently, always turn the reflector at least to the 60° lock-in position. The light bounced off the reflecting surface produces a soft and uniform illumination of the subject. The reflecting surface must be white or have a neutral colour, and it must not be structured, e. [. . . ]
