[. . . ] They could be blinded by the light and cause an accident!Flash fired directly in front of the eyes of a person or animal can damage the retina and lead to severe visual disorders even blindness!Only use the approved power sources listed in the Operating Instructions! Do not expose batteries to excessive heat, sunshine, fire and the like! [. . . ] 3 Removing the flash from the camera  Turn off the camera and the flash by the main switch. 1 Suitable batteries The flash can be operated with any of the following batteries: · They permit very fast recycling and are economical in use because they are rechargeable. They have a significantly higher capacity than NiCad batteries and are less harmful to the environment (no cadmium). Free power source for moderate power requirements. Cell voltage may damage the electronic system of the flash unit. 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. Turn off the flash by its main switch. 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. The middle third of the zone between the minimum distance and the maximum flash range to give the electronic circuit sufficient leeway for light control. You choose the f/2, 8 "green" auto-working aperture (maximum flash range given by the aperture calculator: approx. 2 Manual flash mode , , M" The flash always fires uncontrolled flashes at full light output when in manual mode. Their design they can cause a loss of light of as much as one aperture increment. They may also have different effective aperture values for the different focal length settings. This will then have to be compensated by manual correction of the aperture setting on the flash unit!1 Manual flash mode with a given aperture · The flash unit's aperture calculator indicates in metres (m) or feet (ft) the camera-to-subject distance required for the individual fstop. 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). [. . . ] The reflecting surface must be white or have a neutral colour, and it must not be structured, e. The following rule of thumb will help you determine the maximum flash range for a room of normal height: Guide number Maximum flash range = ­­­­­­­­­­­­­­­­­­­­­­­­­ (flash-to-subject distance x 2) Remove any grime and dust with a soft, dry or silicon-treated cloth. Never use detergents that could damage plastic parts. Forming the flash capacitor The flash capacitor incorporated in the flash unit undergoes a physical change when the flash unit is not switched on for prolonged periods of time. [. . . ]
