4 LED displays on the flash unit

4.1 Flash readiness indication

When the flash capacitor is charged, the flash readi-
ness symbol

ቤ lights up on the flash unit, indica-

ting that the flash is ready to fire. This means that flash
light can be used for the next shot. Flash readiness is
also transmitted to the camera and indicated accor-
dingly in the camera’s viewfinder (see 6).

If a shot is taken before the flash readiness indicator appears in the camera’s
viewfinder, then the flash unit will not be triggered and, if the camera has alrea-
dy switched to flash sync speed (see 11.1), the shot may have the wrong expo-
sure.

4.2 Correct exposure indication

The correct exposure indication „OK“

ብ only lights up

for about 5 seconds if the shot was correctly exposed
in TTL flash mode (

, P

HSS

; see 7)!

If no „OK“ exposure indication appears after the shot,
then the shot was underexposed. You will need to
repeat the shot with the next smaller f-number (for

example, f/8 instead of f/11) or the distance to the

subject or reflecting surface (for example, with bounce flash) will have to be
reduced. Note the maximum flash range indicated on the display of the flash
unit (see 5.2). For information on the correct exposure indicator in the camera
viewfinder, also see 6)!

5 Information in Display

Most cameras transfer the values for the ISO, 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 and zoom position of the main reflector are
displayed in the display of the flash unit.
If the flash unit is operated without having received data from the camera, only
the flash mode selected, the zoom position of the main reflector and „Zoom“ is
displayed. The readout for the range occurs only once the flash unit has recei-
ved the required data from the camera.

Auto-Zoom and flash range are only displayed on cameras where the
aperture and ISO values are transmitted to the flash unit!

Display illumination
Every time a button on the flash unit is pressed, the flash display illumination is
activated for 10 seconds. When a flash is fired via the camera or the hand
release

ቤ on the flash unit, the display illumination is switched off.

5.1 Display of the flash mode

The current flash mode is shown in the
display. Depending on the type of camera,
different displays are available for the selec-
ted TTL flash mode (e.g.,

, P

HSS

) and the

manual flash mode M (see 7).
