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!
13 Triggering control (auto-flash)
On some cameras the flash will not be fired when the prevailing light is sufficient
for an exposure. When the camera shutter release is depressed, no flash exposu-
re is triggered.
In various cameras the triggering control only works in the full program mode or
„P“ program or must be activated on the camera (see camera operating instruc-
tions).
14 Care and maintenance
Remove dust and grime with a soft dry cloth or silicon-treated cloth. Do not use
cleaning agents as these may damage the plastic parts.
14.1 Firmware updates
The flash unit’s firmware can be updated through the USB port
ቯ
and adjusted
to the technical requirements of future cameras (Firmware Update).
For more information, visit the Metz homepage at www.metz.de.
14.2 Reset
The flash unit can be reset to the factory settings when delivered. Press the
ìModeî button for ca. 5 seconds. After ca. 5 seconds „rES“ (= Reset) is shown in
the display and the flash unit is reset to the settings as delivered..
This will not affect the firmware updates for the flash unit.
14.3 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 indicator to light up no more than one minute after the flash unit is
switched on.
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
