21.3 Flash capacitor forming
The flash capacitor built into the flash unit undergoes physical change if the unit is
not switched on for a prolonged period. For this reason it is necessary to switch the
unit on for approximately 10 minutes at least once every three months. The power
supplied by the power source must be sufficient to cause the flash readiness indica-
tor to light up no more than one minute after the flash unit is switched on.
22. 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.
TILT" appears on the display
• The main reflector is tilted downwards for close-up or macro shots.
"POWERPACK" appears on the display
• An unauthorised power pack has been connected to the mecablitz. Use only a
Metz Power Pack P76.
A battery warning appears on the display
• When the battery warning appears on the display there is still enough power
☞
left for a few more flashes. See also chapter 3.2 "Replacing batteries". There
are, however, battery batches with which the battery warning appears relative-
ly early, even though there may still be up to 50 % of the flashes still available.
In wireless remote mode it is not possible to provide a battery warning for
system-related reasons.
A battery symbol appears on the display
• There is a Metz Power Pack P76 connected to the mecablitz and there are bat-
teries in the battery compartment of the mecablitz. Remove batteries from the
mecablitz.
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.
Second curtain synchronization (REAR) cannot be activated on the flash unit.
• Second curtain synchronisation can only be used with cameras which support
this function.
• The REAR function can be selected and activated on the flash unit only if an
exchange of data has been effected between the flash unit and the camera, for
example by tapping the shutter release.
The reflector position is not automatically adjusted to the current zoom position
of the lens.
• The camera is not transmitting any digital data to the flash unit.
• There is no exchange of data between the flash unit and the camera. Tap the
camera’s shutter release.
