18. Troubleshooting hints

No display in "ON" switch position.

Brief movement of the "ON" switch in the direction of "OFF" without overcoming the click stop enables the unit to change over to stand-by mode (display off) even though the switch is still in "ON" position.

Remedy: The unit is switched on again by normal actuation of the switch to the OFF setting, followed by "ON", or simply by pressing the "PLUS" key.

Flashing operating mode symbols

First of all check if the mecablitz is locked, and if the operating mode selector is correctly positioned.

Meaningless information

Should the LC display indicate meaningless information or should the flashgun not work properly in the individual modes, then proceed as follows:

Switch off the flashgun by its main switch.

Remove the batteries.

Switch on the flashgun for approximately 1 second and then switch it off again.

Reload the used or new batteries.

Lithium batteries feature an overload protection which prevents them from becoming overheated. The overload circuit responds to extreme loads (numerous flashes within a short period). In such an event the recycling time is considerably lengthened. Switch off the flashgun and allow the batteries to cool down.

A flashing battery warning signal with only moderately warm lithium batteries indicates that the batteries have become exhausted.

18. Troubleshooting hints

Battery warning indicator

A flashing battery warning display indicates that the batteries are exhausted*.

Remedy: Should the battery warning indicator continue to flash even after the batte- ries have been exchanged, then

switch off the flashgun with the main switch . Open the battery com- partment cover and remove the batteries. Switch on the flashgun by its main switch for approx. 1 second, and then switch it off again. Reload the new batteries, and the battery warning indicator will cease to flash.
