+
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

ficient to cause the flash readiness indica-
tor to light up no more than one minute
after the flash unit is switched on.

not the case, contact your local dealer.
