EIEFGIFIE FLASHING

 Inserting batteries
 (1) Remove the battery compartment  lid from the bottom of the flash unit.
 (2) Insert the cartridge into the battery compartment by keeping the con'
     tact facing upwards as shown.
 (3) Replace the battery compartment  lid.
 The alkaline-manganese battery is ideal for the electronic flash photography
 where a large amount of energy is required.  lt excells the manganese  bat'
 tery in discharging performance and always provides stable voltage.



Operation'on batteries
 ( 1) Set the AC/DC selector switch to DC. Oscillating sound  is
     audible from the flash unit, when the DC circuit becomes
      on.
(Z) fne neon lamp begins to glow when batteries are fully
    charged. Now you are ready to make a flash.(3) When not in use, be sure to turn off the DC circuit by   Effig
     setting the switch to AC. lf the switch is on for extended
     period,  it will cause a waste of batteries.                         www.butkus.us

Operation on AC household current
(t) set the AclDc selector switch to AC and insert the Ac
    cord into the AC cord socket. plug the AC wall ouilet.
(2) Ttre neon lamp begins to glow (No oscilrating sound is au.                       l-+     dible.) when the batteries become fully charged. Now you   @                                            t=i    are ready to make a flash.
 r   Note:  . The rated voltage of this flash unit is lO0- I2OV or
         220- 240V. (Throgh transformer  )


Open flash
Push the open flash button after the neon lamp starts glowing   .
Then the flash unit gives a flash without pushing the camera's
shutter release.

Synchronization with camera
Be sure to use the X contact terminal for flash synchronization.  Other
terminals, M and FP, do not synchronize with the camera.
( t) Wnen the camera has two contact terminals, use the X contact.
(2) When the camera has a contact selector ler,er, set it to "X".    W(3) When the camera has only one contact, it is for X synchronization
     in most cases. Make sure of it, with the manual that comes with
 .  the camera.

      Settingl the shutter speed
          ( 1) When the camera has a between lens shutter, the flash unit synchronizes with all of the
          shutter speeds.
     (Z) tn the case of focal plane shutter camera,  the flash unit synchronizes with the shutter
         speed that is indicated by X mark or red figure, or with slower speeds. Note that the
           synchronization speeds differ with cameras.  and make sure of them with the camera's
          operating manual.
     Automatic operation
      * This flash unit works automatically at three different lens openings.
        (F/stop selector    FSS....system)
 I    * fhis flash unit combines a Computer with a thyristor (semiconductor switching element).
       Consequently, it offers the convenience of very short recycling times in close-distance photo-
       graphy, and permits rapid shutter release in succession.I
     (1) The ASA speed of the film being used is set to the ASA indicator on the expostrfd cafcu.
I         lator dial.
     (2) Select the F value of this model which is appeared inside the Auto/Manual Indicator Window
        by turning the knob of the Auto/Manual selector dial.
         Before you set your camera's F/stop value, please do not fail to select the color showing
           inside the Auto/Manual Indicator window reading the line for the color indications on Exoo-
         sure Calculator  Dial.
     (3) When operated automatically, the flash unit automatically provides the proper exposure
         without relation to the distance between the unit and the subject. And it permits .the use
         of pre-selected F stop, regardless of whether the unit is with an attachment or wide-adaoter.u

where it is converted into electric signals.
These signals will automatically control the flash when pre-selected exposure is attained.
This computer uses a thyristor (semiconductor switching element) to store extra energy(which
occurs when the flash is cut off) in a capacitor that is then discharged to supply light for ex'
posure. In this respect this flash unit differs from the ordinary electronic flash units which
dissipate extra energy through bypass circuits.
                                                                                    saving of bothThe advantage of this computerized unit is Quick Cut and Charge (QCC) -  the

       In general type hand grip Electronic flash unit is situated flash tube at higher location than the
      center of lens on camera so that it is recommendable to face the electronic flash unit toward
      subject or to use wide adapter included in the set.

    CAUTIclN

     (1) A high voltage and large power capacitor is built in the unit. In case of disorder, do not
         attempt to repair by an unqualified hand.
     (2) Keep the flash unit out of moisture, rain and water.
     (3) When the unit is not used for a long period of time, the capacitor becomes void of power,
        and will take time to become charged at first.
     (4) lf it is not used for a long interval of time, charge it on the house current once a month.
           It keeps the capacitor in the best condition.
    (5) Take the dry cells out of the compartment  if the unit is not used for a long time.
]    (6) Replace  all of the cells to renew them. Use the Cells for the best result.
