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 ቢ 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.
• There has been no exchange of data between the flash unit and the camera.
Tap the camera’s shutter release.
• The main reflector is not in normal position.
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 position
of the lens.
• The camera does not transfer data to the flash unit
• There is no exchange of data between the flash unit and the camera. Tap the
camera’s shutter release.
☞
• The flash unit is set to manual zoom setting “MZoom”.
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 setting for manual TTL flash exposure correction has no effect.
• The camera does not support manual TTL flash exposure correction on the flash
unit.
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 flash unit works with high-speed synchronisation (FP or HSS). Switching to
sync speed does not occur in the process.
• The camera operates with shutter speeds that are slower than the flash sync
speed. Depending on the camera mode, there is no switch to flash sync speed
(see the camera’s operating instructions).
The shots have shadows in the bottom of the image.
• Because of parallax error between lens and flash unit, close-up shots may not,
depending on the focal length at the bottom of the image, be fully illuminated.
Tilt the main reflector downwards or turn the wide-angle diffuser in front of the
reflector.
The shots are too dark.
• The subject is beyond the range of the flash unit. Note: Using bounce flash
reduces the range of the flash unit.
• The subject contains very bright or highly reflective areas. The metering system
of the camera or flash unit is deceived as a result. Set a positive manual flash
exposure correction, e.g., +1 EV.
