3. Kindof oPerotion
The ULTRABLITZJET ll unit is provided for dry cell,
occumulotoror A-C operotion. Before opening the
unit pull plug qnd disconnectflqsh heod cord from
u nit.


    o) Dry cell operofion
   Be sure thot unit is turned on dry cell operotion.
   The three screws must be insertedin the left row
    of the bottery storoge, while the right row re-
   moins open. Four bqtteries CIreclomped in the
    unit between the springs qnd contoct strips so
    thqt qll smoll contoct cops ore showing upwords
    crs it is shown in the bottery storqge of the dio-
   grqm. Insertfirst left top cell ond push it strongly
    qgqinst the upper spring, then insert the cell
    below, ofterwqrds the right top cell ond finolly
    the lost below. The selector crqmp (o) must be

set to "Operotion". (How it is done see section8)
Switchingon qnd off is done by o switch on the
to rch.





b) Accumulotor ope ration
For the operotion with occumulqtorthe qbove
mentioned th ree screws must be screwed in the
right row of holes of the bottery storoge, then
you con insert the occumulotor so thot the
occumulqtor window  with  its floot tubes is
showing towords the control window. Connect
short leod of the CIccumulotorwith upper con-
toct ond the long leqd with the lower contoct.
The power selector cromp (o) must be set to
"Operotion". Switching on ond off is done by
o switch on the torch.

c) A-C operofion




The line voltoge selectorlever is set to
220 volts by the foctory. lf the locol line
voltoge does not correspondto th e pre-set
voltoge of the foctory remove the cover
plote ond set the voltoge selector lever
to the correspondingvoltoge.Pullplug out
of iocksond possitoutsidethe cosethrough
the openingin thecoverondreplocetheco-
ver. The unit is turned on by insertingthe
 pf ug to the line socket. (There is no bvzzing tone to be heord). The switch
 on ihe torch hos no effect in A-C operotion.Signol light shows reqdinessfor
 operotion. With A-C operotion the unit ccrn only be switched off by with-
 drowing the connector plug from the line socket. For tronsportotionwind
 up line cord in the unit ond-insertplug into the iocks.(The unit is now ogoin
 reody for botterY oPerotion).

4. Adiustingangleof illuminotion





                         By switchingthe smoll lever on the flosh heod, the
                           ongle of  illuminotion cqn be chonged from 50o

5. Selectionof lightingPower

power selection is qnother woy of odopting the unit to porticulor require-
ments. At  full power ond short ronge, overexposure con occur, especiolly
on high speed blqck-ond-white film. ln thot cose use holf-power. For color,
olwoys use full power. The power selector hos iwo positions:
       @il    EN
                        full power               holf power


 It is best for your unit to operote the power selector slowly ond immediotely
 ofter floshing. Remember thot q set of dry cells or the occumulqtor will yield
 considerobly more floshes of holf power thon qt  full power. Also, o con-
siderobly more ropid flosh sequenceis permissible.Photogrophicolly,chong-
 ing from hqlf to full power omounts to o goin of one diophrogm stop; or,
 under otherwise equivolent conditions, 50 "/" more depth con be lighted'             il

6. Settingof diophrogm:stoptoble,guidenumber
      In ULTRABLITZphotogrophy,exposure is generolly controlledentirelywith the

     22 feel, opposite the film being used, for exomple 50 ASA, find the proper
     diophrogm setting,in this cose 8.

     Note thot the stop toble on the flosh heod is plonned for comporotivelylong

      Sotisfoctory negotives will be obtqined  if  films qre developed 2A-25%

     cqlled for  in the toble. The wide-ongle setting colls for q further opening
      of diophrogm operture by one stop.

          7. Jilmcnd developing





             JEt  ll light is equivolent to doylight (5600"K.). Therefore olwoys use doylight
             (negotive or reversible)film for color exposures.The guide numbers for
              color film c,onnot be determined from the ASA volues specified for  it. For
             block-ond-white exposures, it is best to use ponchromotic film, not too soft'
            Usuolly o fine-groined equolizing developer is odvisoble.Very fine-groined
            developers ore not recommended becouse the grodotion is often too  flqt.
                                                              o/o             Block-ond-white film is usuolly developed 2C*l25   longer.
            Reversiblecolor film will not permit lengthening of developing time.        15

                         b) Rechorging lhe occumulotor
                   A thorough core qnd mointenonceof the occumulotor
                    ensuresproper functioning of oll times. As soon qs one
                         or severol floots hqve sunk to the bottom the occumulotor
                     should be rechorged. Rechorgingis very simpte. Set the
                      selectorcromp to "Chorging".(Thisis done by lifting ond
                      turning the selector crqmp to the position,,Chorging,,).
                   Then plug the line cord connector ptug of the unit into
                       the line socket ond chorging storts immediotety.Rechorg-
                        ing  is completed ofter 3 hours when block floqts or"
1 6                swimmingof the top.

www.butkus.us

Rechorgingof o completely dischorgedclccumulotorwill
be completed ofter  l6  hours. Even during extended
periods of disuse,the qccumulotorshould be rechorged
every three weeks in order to mointoin its full output.
After chorging check the ocid level qt once, which must
not exceed the upper mork, otherwise the occumulotor
ceqses to be spill-proof. lf the ocid level hos d ropped
b e lo w t h e lo we r mork,top it up with d  i st  i I I e d w o  t e  r
until the level reoches the upper mork qnd rechqrge it
qgoin fo r 1/zhour. (Follow properly instructionsof Sonnen-
schein-Typebooklet).



c) Re-forming fhe sforoge condensers
After q period of q few weeks without use, we recommendrunning the unit
from 1/+to 1/2hour plugged into A-C. The power selectorshould meonwhile
be set to full power. This procedure, without flqsh operotion, will re-form
the storoge condensers,so thot you will get the moximum number of floshes
 per occumulqtorchorge.                                            1 7

                          It is often very desiroble not to ottoch the flqsh to
