4.2 Correct exposure indication
The correct exposure indication „OK“ only lights up for about 5 seconds if the
shot was correctly exposed in TTL flash mode ( , HSS; see 7)!
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).
5 Information in Display
The 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 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 display for range only occur once the flash unit has received the
data required 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 selected TTL flash mode (e.g.,
, 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, down-
wards or sideways).
- the flash unit is working in remote flash operation (slave SL).
Range display in TTL flash modes
In the TTL flash modes ( , HSS; see 7.1) the value for the maximum range
of the flash unit is displayed. The value indicated relates to subjects with a reflec-
tion factor of 25%, which applies to most photographic situations. Strong devia-
tions from this reflection factor, as in the case of highly reflective or poorly reflec-
tive 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-
pensation. To avoid overexposure, the minimum distance should be no less than
10% of the indicated value! Adjustment to the photographic situation at hand
can be achieved by, for example, changing the aperture of the setting on the
lens.
Range display in manual flash mode M
In manual flash mode M, the distance that must be maintained from the subject
for correct flash exposure is indicated. Adjustment to the photographic situation
at hand can be achieved by, for example, changing the aperture setting on the
lens or selecting a manual partial light output level (see 7.2).
