Hershey Sunlite and Super Sunlite Press User manual

welcome to the world of hershey
We of hershey appreciate and thank you for your purchase of one of our
Sun-Lite Press or Super Sun-Lite Press power supplies. These two models
are very similar in construction,,function, and use. The basic difference in
the two is the higher power output of'the Super Press. We have, for this
reason, combined in this manual the instructions for the use of both.
The Sun-Lite Press and Super Sun-Lite Press are designed to meet the most
demanding electronic flash requirements of the professional photographer.
They are high performance, rugged pieces of equipment that have earned
a well deserved record of excellence.
They contain electronic components that require the normal degree of care
in handling that you would give to any fine instrument.  .
Properly registered, your hershey Sun-Lite Press or Super Sun-Lite Press
is guaranteed to the original purchaser against defects in material and
workmanship for one year.
Please complete and mail the enclosed registration of guarantee card TODAY.
                                       Sincerely

                  FEATURES
The Sun-Lite Press and Super Sun-Lite Press are lightweight, portable electronic
 power s!pplies designed for use with a compatible series of hershey photographic flash
 heads. Both models are similar in function, features, and operation. They inciude com-
 pletely solid state circuits with a minimum of moving parts.                                                                                             F
These two models differ basically in the amount of power they                                                       -Piessprovide. The Super Sun. Lite Press produces 2OO watt seconds and the Sun-Lite      L4O watt seconds

In determining your selection of a flash head, you may find it to be of value to make
reference to one of the several well accepted books currently published that explain
the techniques employed in electronic flash photography. These books can usually be
obtained from your local photo dealer.
CONNECT FLASH HEAD
All electronic flash units contain a component known as a capacitor. The capacitors in
the Press and Super Press models store electrical energy at the high voltages required
to produce a flash of light in the light tube.
   WARNING: THESE cAPAcITORs MUST NOT BE CHARGED WHEN YoU
           ATTEMPT TO ATTACH A FLASH HEAD.

         An electrical corona_.discharge (arcing).may occur that will severelydamage either the
          power supply or the flash head - or both.
       A Press or Super Press that has been in the "OFF" condition for 15 minutes or more
          can be considered non'energized. The stored electrical energy in theiupu.ltoiwill have          decayed during this period.

PREPARATION FOR USE con'l.
A fresh battery is vital to the proper functioning of your Press or Super Press. Assure
yourself that the battery you purchase is NEW -  with as little shelf life as possible.
          o  Remove the two screws holding the face plate in place.
          o Remove the face plate.
          o Remove the plastic tape covering the electrical termi-
                 nals of the battery.
      O Place battery in unit with terminal-end down. The
                  battery contacts must make contact with the spring
                 contacts in the base of the unit.
      O Replace face Plate.
                                                                 plate.        o Replace two screws that retain face
hershey recommends that you leave the battery in the pack unless you plan to idle it for
an extended period of time (more than one month). Batteries of this type have a max-
imum shelf life of between L2 and 24 months. This period will depend upon the tem-
perature and humidity environment in which the batteries are stored. This type of
battery is designed to restore its charge between periods of use. The total life of the
battery may be reduced significantly if it is subjected to maximum drain within
a short duration.
The photographer who experiences heavy equipment usage should carry a spare           ilbattery. We recommend that when it is possible to do so, batteries be changed half
way through a heavy photographing session. lf you take this precaution neither batterywill be excessively drained and the effective total life of both batteries will be signifi-      tcantly lengthened.

   NOTE: MOVE THE SWITCH TO THE OFF POSITION AFTER SHOOTING. THIS
         WILL CONSERVE BATTERY LIFE.

PRIOR TO FIRST USE
Guide numbers are iust what the name states - GUIDES. These numbers are not abso' lute and unchanging values. lndividual flash units have varying characteristics that
 result from differences in the efficiency of the battery, reflector, components in the
electrical circuit, and flash tube. hershey recommends that you take a series of brack'                                                                                                                          I
eting test shots, following these instructions, with any electronic flash unit prior to
an actual photographing situation. Keep a record of film used, f/stop settings, dis-
tances,speeds and power settings. In this way you can establish your own guide num-
bers that will give you consistently correct exposures. These many variable elementschange over time and protracted use. Periodic checks should also be made to insure            tI
the validity of your original calculations.
SET POWER LEVEL
                         power selection switch located on top of unit.   o Depress indicated
                   POWER LEVEL WHILE UNIT IS RECYCLING   o DO NOT CHANGE
CHECK FLASH HEAD REDI.LITE
When this light is first actuated the flash head is capable of delivering about 8oo/o of
its maximum light output for the particular power level that you have selected.                                                       I    o Should you desire maximum light output prior to making your shot, wait          approximately 5 sec. (this time will vary depending on the power level       I           selected, the charge condition of the batteries and individual characteristics
          of each unit).
    o  lf more than 10 seconds are required for the Redi-Lite to actuate, the bat-
          tery should be replaced as previously described.

OPERATION
SET CAMERA SHUfiER SPEED
    o Cameras with leaf-type shutters, use shutter speed of l/100 sec at sync.
    o  For cameras with focal plane shutters, foltow the camera manufacturer's
            instructions for use with electronic flash equipment. (These will generally
         recommend shutter speeds of L/25 to 1/60 sec.)

DETERMINE f/STOP SETTING
Use the following tables to select the guide number for the film you plan to use.
    o  hershey equipment is designed to produce a flash of light with a color tem-
          perature approximately that of natural, noonday, sunlight (6,4000K).
   O Use "daylight" ratings in determining ASA numbers and exposure indexes
          of black & white film.
   O For work with color film, use the manufacturer's recommended filter and
          color correction information as specified for "speedlight" equipment.
    o Read across the table to determine the correct guide number for the power           level (full, Vz, or t/il be,ng used.
    o  Divide the distance from lamp to subject into the guide number obtained
         from table. The resulting quotient is the proper f/stop.

MAINTENANCE
        OF YOUR SUN.IITE PRESS AND SUPER SUN-IITE PRESS
        Your hershey Press or Super Press is a rugged, professional piece of equipment. lt is
         also a precision electronic instrument. Practice the following precautions.
 t           O Turn unit off and discharge capacitors by flashing be-
                           fore connecting or disconnecting flash heads.
t                   Remove alf dust, moisture, or corrosion from con-
                              nectors.
                        Allow futl capacitor charging time between flashes.
                          Rapid, repeated flashing may cause damage.
                        Frayed cables should be replaced immediately.
                         Unless you are familiar with electronic equipment we
                      recommend that you not attempt to repair your unit.
                  We suggest you return it to the factory or let us advise
                     you of the hershey authorized repair facility in your
                             area.
