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 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

to switch on again.

m-ft display

Testing the LCD segments and m-ft changeover (Service Menu)

The Service Mode 1 has to be called in order to check the LCD segments and to change over the dimensional units (m = meter; ft = feet).

Only complete the settings described here! Do not press any other buttons than those described here, otherwise there is the danger that programmed data and user programs will be lost!

Calling the Service Mode 1:

Press the button

for the LC display light and simultaneously slide the main

switch

for

at least 2 seconds after sliding the main switch .

 

SEr1 and m or ft flash, and an index number, e.g. 1.0 is indicated.

Adjusting the dimensional units:

m or ft is selected with the „+“ button

.

Testing the display segments:

Remove the adapter from the mecablitz

Press the button for the LC display light. All segments of the LC display must be indicated.

Return to the User Menu:

Slide the main switch to OFF, and then to ON again.
