4. Wait until both the off-camera flash and built-in flash are charged.
In remote mode, the off-camera flash's AF illuminator and flash-ready
signal will blink when the flash is charged. The flash-ready signal in the
viewfinder will blink when the built-in flash is charged.
5. Press the AE lock button to test-fire the off-camera flash and wait again
until both flashes are fully charged.
