14.2 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 sufficient to cause
the flash readiness indicator to light up
no more than one minute after the flash
unit is switched on.
