4 LED displays on the flash unit

4.1 Flash readiness indication

When the flash capacitor is charged, the flash readiness symbol
on the flash unit, indicating 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 accordingly 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 exposu-
re.

4.2 Correct exposure indication

The correct exposure indication „OK"
shot was correctly exposed in TTL flash mode (
If no „OK" exposure indication appears after the shot, then the shot was under-
exposed. 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 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 selected TTL flash mode (e.g.,
TTL TTL TTL
, P , P HSS) and the manual flash mode M (see 7).

5.2 Range display

The flash range is displayed when using cameras that transmit ISO, lens focal
length and aperture data. For this a data exchange must have occurred between
the camera and flash unit, for example by tapping the shutter release. The range
can be displayed either in metres (m) or feet (ft) - see 9.7.
The flash range is not displayed when no data is transmitted from the
camera.
- when the reflector head is tilted out of its normal position (upwards,
downwards or sideways).
- the flash unit is working in remote flash operation (slave SL).
Range display in TTL flash modes
TTL TTL
In the TTL flash modes ( , P , P
range of the flash unit is displayed. The value indicated relates to subjects with a
reflection factor of 25%, which applies to most photographic situations. Strong
deviations from this reflection factor, as in the case of highly reflective or poorly
reflective subjects, may affect the flash range of the flash unit.
The subject ought to be in the area of approximately 40% to 70% of the value
displayed. This will give the automatic exposure control sufficient scope for com-
