MAINTENANCE AND CARE

The flash unit should be cleaned with a dry, soft, and lint-free cloth
(e.g. a microfiber cleaning cloth). The cloth can be moistened to
remove stubborn dirt.
Important:
Never use liquid cleaning agents. The components inside the
device could suffer irreparable damage if cleaning liquid penetrates
the housing.
CONDITIONING THE CAPACITOR OF THE FLASH
UNIT
The photoflash capacitor physically deteriorates if the flash unit
remains switched off for prolonged periods of time. For this reason,
the flash unit should be switched on at least once every three
months for about 10 minutes.
The batteries used for this must be able to provide enough power
to charge the capacitor to flash ready state as indicated by the LED
within 30 s after switching on.

TROUBLESHOOTING

If the flash unit does not function as expected, press the power
switch to switch it off and wait for about 10 s. Check that the
mounting foot of the flash unit has been properly inserted into the
accessory shoe of the camera and check the camera settings.
Replace the batteries with fresh ones. The flash unit should now
function correctly when you switch it back on.
Please contact your dealer if this is not the case.
