Operating Your Flash and Running a Test Flash
Slide the ON/OFF switch to the "ON" position. After a few seconds 
the Test/Ready lamp should illuminate, indicating that the flash is ready to use. Press the Test/Ready button to make sure that your flash works properly. If the flash discharges, it should be working 
properly. Wait until the Ready lamp glows again to use once more.
Adjust your camera to the appropriate setting. Most cameras should 
be set to the program position (see your camera's manual for details 
on flash synchronization.) When the flash is ready to fire, it will 
automatically match the camera's shutter speed. The flash readiness 
indicator will appear on the camera. Different camera models indicate
flash readiness in different ways (see your camera's manual).
Point the digital camera at the subject and focus. Press the shutter
button on the digital camera half way down to check the image. Then press the shutter button all the way down firmly. The Auto OK indicator will light when the picture is exposed correctly.
