4 LED displays on the flash unit

4.1 Flash readiness indication

When the flash capacitor on the flash unit is
charged, the button lights up in green,
thus indicating that the flash unit is ready.
This means that flash light can be used for
the next shot.
Flash readiness is also transmitted to the
camera and indicated accordingly in the
camera's viewfinder.
If a photograph is taken before the display
for flash readiness appears in the camera's
viewfinder, then the flash unit will not be trig-
gered. If the camera has already switched to
flash sync speed, the shot may have the
wrong exposure (see 13.1).

4.2 Correct exposure indication

If the exposure is correct, then button
lights up in red for around 3 seconds if the
photograph has been correctly exposed in
flash modes E TTL and E TTL HSS (see 7.1).
If there is no exposure control indication after
the shot, then the photograph was underex-
posed. In that case, you must:
- set the next smaller f-stop (e.g. use f-stop 8
instead of 11), or
- reduce the distance to the subject or to the
reflection surface (e.g. for indirect flashes),
or
D
- set a higher ISO value on the camera.
Note the maximum flash range indicated on
the display of the flash unit (see 5.2).

5 Information in Display

The Canon cameras transmit the settings for
ISO, lens focal length (mm) and aperture to
the flash unit. It calculates the maximum
flash range from the settings and their guide
number.
Flash mode, range, aperture and zoom positi-
on of the reflector are displayed in the
display of the flash unit.
If the flash unit is operated without receiving
data from the camera, then the values set on
the flash unit will be shown.
