The Rapid function
Recycling times in the A and TTL modes depend on the amount of light required
for the shot. Recycling takes 11 seconds max. when full-power flashes are fired.
Should this be too long, the Rapid function comes to the rescue.
Use of the Rapid function is especially valuable when taking shots inside a room,
where fast recycling is more important than a maximum light output. However,
the guide number is reduced by 1 increment, e.g. from GN 40 (with ISO 100/21°
film - 50 mm zoom) to GN 28 (with ISO 100/21° - 50 mm zoom).
Partial light output levels are not possible with the Rapid function.
Automatic cut-out
If you set the multi-function switch
ቮ to the „clock symbol“, the flashgun is
automatically switched off approximately 10 minutes after it was last used, thus
protecting the batteries against inadvertent discharge.
The last used operating mode, or the last set user program is retained when the
flashgun is switched off so that it becomes instantly available when the flash is
switched on. Press the „+“ or „-“ button
ቪ to switch on again.
