13.2 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 suf-
ficient to cause the flash readiness indica-
tor to light up no more than one minute
after the flash unit is switched on.
14 Troubleshooting
If the flash unit does not function as it
should, switch it off for approx.
10 seconds via the

button. Check
the camera setings and that the flash
unit stand is fitted correctly in the
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
