How to turn the Speedlite flash on and off.


Set the power switch to <ON>
  • The flash will start recycling

Check that the flash is ready

  • When the pilot lamp lights in red, the flash is ready to fire
  • To fire a test flash, press the pilot lamp

About Quick Flash

The flash-ready lamp blinks when Quick Flash is ready even before the flash is fully charged. You can use the flash to take a picture at that time; however, the flash output is only half or one-third of the flash's full charge. This is useful for taking pictures of subjects very close to the flash.

About Auto Power Off

To save battery power, the power will turn off automatically after 90 seconds of idle use. To turn on the Speedlite again , press the camera's shutter button halfway.

• The time until auto power off takes effect may increase when firing continuous flashes .

• Auto power off can also be disabled
