Connections           Connect the camera, the lamp unit, and the
                    power pack by the synchronizing lead and
                       the power cable, as shown in the illustration.
                       Set the camera synchronization to X.

                      Hold the lamp unit in the hand, or fit  it
                           into the camera accessory shoe (upright or
                           horizontally). Brackets are available for
                     cameras without accessory shoe. Remove
                       the carrying strap when replacing the unit
                             in the case.
Switching On         Move the switch to "1". During an exposure
                          series the current supply is automatically
                         controlled to keep the flash gun ready to
                           flash with the minimum drain on power.
                When shooting is finished, move the switch
                     back to "0". Never leave the unit switched
                   on unnecessarily     that wastes the batteries.                                         -
Shooting                 Fire the flash only when the indicator lamp
                            lights up, showing that the full power of
                       the flash is available.  (lf the indicator lamp
                      takes a long time to light up, or does not
                   do so at all, the batteries are exhausted.)
                     The flash is fired on releasing the camera
                         shutter or by the manual firing button.

            Camera Settings        Central shutters can be set to any speed,
                                 up to the fastest available. For focal plane
                                       shutters note the recommendations  in the
                                 camera instruction book.
                                The required aperture depends on the film
                                     type and on the distance between the flash
                                 and the subject. The aperture-distance
                                         indicator gives the correct values. To use
                                                                   it, rotate the disc to bring the film speed
                                         figure opposite the red index mark (for
                                      colour film) or the black index mark (for
Hi                                      black-and-white  film). Then read off the
                                       correct aperture for any distance on the
                                       inner scale.

            Changing Batteries    The batteries are exhausted when the
                                         indicator lamp takes more than one minute
                                       to light up after a flash. Never leave
                                   exhausted batteries in the flash unit; even
                                       fresh batteries should be removed when
                                 not in use for long periods. Insert the new
                                      batteries as shown by the marking in the
                                   base. A set of batteries consists of four
                                     miniature 1.5 volt heavy-duty cells (baby
                                           cells), e. g. Pertrix 235.

Average                  Effective flash duration approx. 1/1000 second;
 Performance           wide-angle lighting coverage; colour
 Figures                temperature corresponding to average
                           daylight; one set of batteries yields 120
                         flashes; re-cycling time 10 seconds.                                                 {

Guide Numbers       The aperture required can either be read off                                                                                           {                      from the aperture-distance calculator, or
                    worked out from the guide number. The
                      guide number divided by the distance
                     between the lamp,and the subject is equal
                         to the lens aperture (e. g. guide number
                     60 divided by 15 feet :   fl4). Guide numbers
                     depend on the film speed and apply to
                          light-walled rooms of medium size. The
                        values given below are for colour film; with
                         black-and-white films the guide numbers
                    can be twice as high.
