BATTERY INSTALLATION         www.orphancameras.com





Alkaline batteries are recommended because of  their longer life and endurance to a wider
temperature range. Moreover, their strength is far superior to that of conventional zinc-carbon
batteriesand this powerf ul f lashunit understandablyrequiresconsiderableenergy.
   The thyristor circuitry is power-savingand does allow quite a number of flashesto be made
from a singlecharge with microscopic intervalsbetween flashes.
   N.B. Clean the battery and compartment contacts at regular intervals.Remove the batteries
if the unit is likely to be out of use for a long period.

OPERATINGI NSTRUCTIONS        www.orphancameras.com





Slide the on-off switch to the right position. A humming noise will be heard as the unit is
turned on, which will become fainter when the flashunit is fully charged.At that time the ready
indicator lamp will glow and the unit is ready for operation. After operation, the ready lamp
will glow again almost instantaneuously as the thyristor circuitry provides automatic rapid
recharging.
   The unit can be dischargedby pressingthe ready lamp which doubles as a test button.
   Always ensure that the unit  is switched off after use to save battery consumption and to
preservethe life of the unit.

     Set the knob on  front  of  unit  to  central position. The two  white  dots set adiacent one
    another (Fig.2) serve as an indicator that flash in on manual setting.
        Set the rotating diaphragm disc on the back of the unit in such a position that the speed
      of the film being used appears adiacent the yellow diamond mark (E.G. ASA 1O0 in Fig.3)
        Estimate (or measure for greater accuracy) the camera to sublect distance and then locate
     the nearest greater reading in feet or meters on the top semicircle of the diaphragm disc.

        Read the adjacent yellow  figure on the inner disc to determine the camera lens aperture
       setting (E.G. F5.6 for a distance of say 1Sftl. Please note the readings on the outer disc are
       the maximum  distances at which photographs taken at the adjacent F stop reading will be
       correctly exposed, Ensure that phtographs are not taken out  of the effective range as they
         will be underexposed.

The  built-in  photosensitive  cell measures the  light  emanating from  the  subiect and  the
computor  automatically  determines the correct  quantity  of  light  required. There are two
settings for computor use -  (al for relatively close range where green framed circular window  is
adjacent the white dot  (Fig.4)  and (b) for greater distance where the red framed photocell is
visible adjacentthe white mark (Fig. 5).
   With the diaphragm disc set at the appropriate film speed e.g. 10O ASA  in Fig. 5, one can
choose either Fg setting as indicated by the green arrow or F4 as indicated by the red arrow.
The figure within  the arrows specifies the maximum  distance at which photographs at that
particular diaphragm can be taken. 12ft  is the maximum distance specified in the green arrow.
Therefore for distances ot 12lt or less the green setting (a) should be selected and the camera
lens should be set at F8 stop.

For distances in excess of 1 2ft but less than 25ft the red setting (bl should be selected and the
camera lens should be set at F4 stop,
   As can be seen in Fig. 7 when 25 ASA Film is being used the green setting (al for distances
up to 1 2ft corresponds to F4 setting, while red setting (bl for distances up to 25ft corresponds
to F2 setting. Should the film speed (e.g. ASA 641 be such the green arrow falls between two F
stop readings choose the nearest yellow figure to the right of the arrow (e.g. F5.61.

    The angle of flash can be elevated from horizontal position for conventional flash photography
      to vertical position for reflected flash by turning the knob (Fig.8,9).  The light is reflected
      satisfactorily provided  that  the ceiling  is flat-surfaced, of average height and not  of a dark
      non-reflective colour. The  benefit  of  reflected  light  is that   it  results in  soft, shadowless
     photographs.
       The computor functions normally  in bounce flash photography, However, the camera lens
     should be adiusted to an aperture one to the right of that indicated by the arrow for 45o flash
     elevation and two stops to the right for vertical elevation.
         Refer: to  Fig. 6 where film speed setting is at 100 ASA. The green arrow points to F8 setting
       for 12ft maximum range. For vertical bounce photography up to this distance the camera lens
     should be set at apeFture F4 in this example (two stops larger aperture than F8)'

DETACHEDOPERATION           www.orphancameras.com




 It  is possible to use the flashunit detached from the camera for flashlight reflection from
vertical objects such as a wall. The flashunit.sbould be attached to the camera by connecting
the P.C. cord to the camera 'X'socket.  The same apertures as those specified for vertical
bounce apply.
      lf  possible for  wall reflection the flash unit should be attached to the camera and the
combination held so that the camera base is vertical to the ground.
   Warning: lf the fiashunit is being used detached from the camera, it should always be held in
such a way that  it is at right angles (90') to the camera. lf  it is employed whilst in the same
horizontal or vertical plane as the camera or at an obscure angle it may be that the direct or
reflected light does not provide sufficient coverageto expose the whole subject appearingin the
viewf inder. Under exposed portions may then appear in the photograph.
