[. . . ] After a picture is taken, and the film receives appropriate exposure, the Ready Lamp will blink. If the Ready Lamp does not blink, it indicates that the flash light was not sufficient for that particular situation. The AF Auxiliary Light will turn on automatically as you focus on a dark area. Note: Effective distance is up to about 0. 7 to 9 meter (2. 3-29. 5 feet). [. . . ] Do not use a thinner, Benzene or other cleaning agents to remove dirt or finger prints from the component. For extended storage, choose a cool dry place, preferably with good ventilation. It is recommended that the flash be charged and fired several times a month, to maintain proper capacitor functioning. USING FLASH IN OTHER CAMERA MODES Shutter Speed Priority Setting By selecting the S mode of the camera, you can set the shutter speed from 30sec. When you set the desired shutter speed, the camera will select the appropriate aperture value for the background. If the subject is too light or too dark, the aperture value indicator will blink and show the limit values (maximum or minimum aperture). In such as case, the camera proceeds to take flash photograph at the limit value. Thus, the main subject in the picture may be exposed correctly, but the background will become under or over exposed. Aperture Priority Setting By selecting the A mode of your camera, the camera will select the appropriate shutter speed for the background. If the subject is too bright or too dark, the shutter speed indicator will blink and show the limit highest or slowest shutter speed value. The highest shutter speed will be limited to the camera's normal flash synchronization speed. In such a case, the camera proceeds to take a flash photograph at the limit value. Thus, the main subject in a picture may be exposed correctly, but the background will become under or overexposed. When used with M Mode You can set the desired shutter speed and aperture value. If you adjust exposure according to the exposure meter indication, the camera will work as for Daylight synchronization flash or slow synchronization. DESCRIPTION OF THE PARTS (fig. 1) 1.

Slide the flash unit's Power Switch to MH (full flash power) or to ML (1/16 flash power). Focus on the subject and set the camera's F-stop, using the exposure calculated by the formula shown below: F-stop = Guide Number (G. N. ) ÷ Flash to Subject Distance (m) 4. After the flash is fully charged, press he Shutter Release button to take the picture. Guide Number will change according to the Zoom Head position, (seechart. 2). Guide Number will also change according to film speed (ISO), (seechart. 3). In the case of non-ISO100 speed films, multiply thechart. 3number by thechart. 2number. For example, using ISO200 film, Zoom Head position for 24mm and the MH mode; multiply the chart. 3 number "1. 4" by the chart. 2 number "34. 0": 34. 0×1. 4=47. 6. [. . . ] Be sure the + and ­ ends of the batteries are aligned according to the diagram in the chamber (fig. 3). After few seconds, the Ready Lamp will light, indicating that the flash unit can be fired. Please press the "Test Button" to be sure that the flash is working properly. If the battery power is not sufficient, or if there is an electronic information error, the BOUNCE FLASH When you take a photo with flash in a room, sometimes a strong shadow will appear behind the subject, if you point the flash head upwards or sideways to reflect the light off the ceiling, wall etc. [. . . ]
