Problem Solution
The flash is stuck in the camera
hot shoe. Make sure that the mounting foot lock is released (Page 13).
The flash is turned on but won’t
fire. Make sure that fresh batteries are installed and in the proper orientation
(Page 12).
The flash is set up as a wireless
TTL slave but won’t fire. • Make sure that the master flash is within the transmission range and
the wireless sensor on the slave is pointing toward the master flash.
Remove any obstructions in the line of sight between the two
(Page 30).
• The ambient light may be too high (Page 31).
The flash is set up as a manual
(optical) slave, but the light is not
noticeable in the picture. Make sure that the flash is set to the appropriate slave mode (Page 29).
The edges of images look dark. Make sure that the flash zoom setting corresponds to the focal length of
your lens (Page 20).
