15 Troubleshooting
Should the flash unit fail to function properly or meaningless content
appear on the flash unit display panel, switch the flash unit off with the
main switch
for approximately 10 seconds. Check the camera settings
and make sure the foot of the flash unit is mounted correctly in the
camera’s accessory shoe.
Replace the batteries with new or freshly charged batteries.
The flash unit should function normally again once it is switched back on. If this
is not the case, contact your local dealer.
Below is a list of some of the problems that may occur when the flash unit is
used. For each item, possible causes and remedies for the problem are listed.
No maximum flash range indication appears on the display panel.
• The main reflector is not in normal position.
• The flash unit has been set to remote operation.
The AF measuring beam of the flash unit is not activated.
• The flash unit is not ready for firing.
• The camera is not in Single AF mode (S-AF).
• The camera supports only its own internal AF measuring beam.
• Some cameras support the AF measuring beam in the flash unit only with the
camera’s central AF sensor. If a peripheral AF sensor is selected, then the AF
measuring beam will not be activated in the flash unit. Activate the central AF
sensor.
The reflector position is not automatically adjusted to the current zoom posi-
tion of the lens.
• The camera is not transmitting any digital data to the flash unit (Group A
cameras).
• There is no exchange of data between the flash unit and the camera. Tap the
camera’s shutter release.
☞
• The camera is equipped with a lens without CPU.
• the flash unit operates in manual zoom mode „MZoom“. Switch to Auto-Zoom
(see 9.1).
The aperture setting on the flash unit is not automatically adjusted to that of
the lens.
• The camera is not transmitting any digital data to the flash unit (Group A
cameras).
• There is no exchange of data between the flash unit and the camera. Tap the
camera’s shutter release.
• The camera is equipped with a lens without CPU.
The indicator for the zoom position of the main reflector is blinking on display
panel
• Warning of shadowing on the edge of the image: the focal length set on the
camera lens (converted to the 35 mm format, 24x36) is shorter than the adju-
sted zoom position of the main reflector.
The TTL fill-in flash
BL cannot be set.
• There has been no exchange of data between the flash unit and the camera.
Tap the camera’s shutter release.
• The camera does not support TTL fill-in flash mode.
• The camera is switched to spot metering. Choose another metering type, for
example multi-zone metering.
The setting for manual TTL flash exposure correction has no effect.
• The camera does not support manual TTL flash exposure correction on the
flash unit (Group A cameras, for example).
Automatic switching to the flash sync speed fails to occur.
• The camera has a between-the-lens shutter (as do most compact cameras),
Switching to sync speed is therefore unnecessary.
• The camera operates with FP high-speed synchronisation (camera setting). In
