16 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.
• There has been no exchange of data between the flash unit and the
camera.
Tap the camera’s shutter release.
• The 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 „ONE SHOT“ mode.
• The camera supports only its own internal AF measuring beam.
• The "AF BEAM" is switched off. Switch on "AF BEAM", see 11.3
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 came-
ra.
Tap the camera’s shutter release.
• The camera is equipped with a lens without CPU.
• The reflector is swivelled out of its locked normal position.
• The wide-angle diffuser folds out from the reflector.
• A Mecabounce is mounted in front of the reflector.
• The flash unit has been set to remote operation.
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.
• The minimum distance (10% of maximum range) has not been rea-
ched.
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 high-speed synchronisation HSS (came-
ra settings). 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 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.
