The Speedlite does not fire.

• The batteries are installed in the wrong orientation.

► Install the batteries in the correct orientation. (p.8)

• The Speedlite's internal batteries are exhausted.

► If the flash recycling time is 30 sec. or longer, replace the batteries. (p.8)

• The wide panel has been pulled out for bounce flash.

The periphery or bottom of the picture looks dark.

• When you set the flash coverage manually, the setting was a higher number than the lens focal length, resulting in a dark periphery.

► Set the flash coverage that is a lower number than the lens focal length or set it to auto zoom. (p.18)

• If only the bottom of the picture looks dark, you were too close to the subject.

► Keep at least 0.7 m/2.3 ft away from the subject.

The flash exposure is underexposed or overexposed.

• There was a highly reflective object (glass window, etc.) in the picture.

• The subject has a very dark or light color.

► Set flash exposure compensation. For a dark subject, set a decreased flash exposure. And for a bright subject, set an increased flash exposure. (p.14)

► With high-speed sync, the effective flash range will be shorter. Make sure the subject is within the effective flash range displayed. (p.16)

The picture is really blurred.

• The shooting mode was set to < Av>, and the scene was dark.
