Auto OK
When the subject is within the Auto Effective Range and there is enough light, the "Auto OK" symbol in the LCD display will blink for about 2 seconds after the flash has been fired.
If the symbol goes out, then there was not enough light for an exposure. In that case, either move closer to the object or select a larger aperture.
Even if the subject is within the Auto Effective Range, the "Auto OK" symbol may not blink due to the color of an object (dark color with low reflectivity).
If the flash is fired immediately after the Ready Light comes ON, the effective range may be reduced. (Please wait 5 to 10 seconds after the Ready Light is ON to achieve maximum power.)
Test Flash
If the Test Button is pressed after the Ready Light is on, it fires the flash. The Auto OK cannot be used for TTL test flash.

Adjustable Bounce Flash Head
The SUNPAK PZ40X includes a flash head that allows you to position the light in a number of vertical positions, in all exposure modes, even in TTL. For more pleasing and creative lighting effects, such as softening shadows on a subject, the Bounce Flash Head of the PZ40X is adjustable vertically up to 90 degrees.
1.Do not attempt to force the Head beyond the settings available, or damage to the flash unit will occur.
2.Press the shutter release button of the camera partway in to check whether the correct aperture and shutter speed are selected.
*Important. Note that the effectiveness of the bounce flash feature is dependent upon the distance to, and the condition of the reflecting surface used.
The angle of the flash must also be set properly to achieve the best possible lighting effects. Aim the flash head at a point on the bounce surface, halfway between the flash and the subject. Normally, when the flash is bounced off a surface, it will usually lose
25 % power or more, even when the surface is white.
Therefore, when a bounce flash photo is taken in TTL mode, it is recommended that you select a larger aperture than for a direct flash photograph.
*Bounce your flash off a white surface whenever possible to achieve the best overall illumination level. Please note that in color photography, when a colored surface is used for bounce lighting, it will reflect its color on the subject.
*When the PZ40X is set to any bounce lighting position, the distance range is not displayed.
