OPERATION:
The Control Panel on the top cf the Strobonar IV contains a selector
switch permitting settings of: "CHARGE", used for recharging the bat-
teries of the unit; "OFF"; "IINE", which permits operating the unit from
AC line current as specified under "DESCRIPTION" on page 3; and
"BATTERY", which permits operation of the Strobonar directly from its
own built-in, rechargeable batteries.
Each working position on the control selector switch is set with a
colored jewel which will glow when the unit is operating or charging.
Proper operating position is thus assured by a quick glance at the control
panel.
The Strobonar IV is equipped with a safety device which permits opera-
tion oI the unit only when the lamp cable is plugged in, and the extension
outlet is either attached to the extension cable, or the extension outlet cover
is in place. This assures complete safety with absolutely no possibility of
contact with high voltage terminals. The "CHARGE" position may, how-
ever, be used without these cables or cover in place. (No high voltage is
present while the batteries are being charged. ) When the selector switch
is turned to the "OFF" position, the capacitors oI the Strobonar are auto.
matically discharged. The charge which has been built up in the capacitors
while operating on battery may, however, be held for a short time by turn-
ing the selector switch to "LINE" even though the unit is not connected to
an AC outlet. This will permit holding a partial charge in the capacitors
during short waits between shots. The batteries of the Strobonar IV must
be filled and charged before the Strobonar can be operated.
When putting the Strobonar into service after a relatively long period
of non-use (over l0 days), it is recommended that the neon indicator
(located in the bac'k of the lamp assembly) be allowed to light once whileView original page 6Page 7 · Read text

operating the batteries. After this initial reforming of the capacitors,
operation may be continued from AC or batteries as desired. Photography
should not be attempted before the neon indicator is illuminated. fne tife
may then be flashed by pressing the manual discharge switch located on the
rear of the Strobonar lamp assembly. I{ the unit has been out of service
for any- appreciable length of time, the charging time may be relatively
long. This may vary from 30 seconds to several minutes, or possibly longer,
depending upon the length of time the Strobonar has been- out of ."ru-ic".
Prior to actual use, the unit should be allowed to reach full charge and
be discharged a number of times until the charging time is on the order
of B to l0 seconds, which would indicate that forming o{ the electrolytic
condensers has been completed and that the unit is now ready {or normal
use.
The manual discharge switch, located on the rear of the Strobonar
lamp assembly, is not used in actual photography except with the shutter
adjusted to "TIME" or "BLJLB" and opened. Except for this case, the
actual flash must always be cause/ by operation of the "X"-contact shutter,
connected to the Strobonar with the appropriate cord.
_ X-contact operation is accomplished by connecting the proper cord
to the shutter contacts and to the outlet in the back of the lamp assembly.
The shutter is then tripped by the manual release or cable release on
the camera. X-contact shutters which are in good repair will permit use
of the Strobonar IV at all speeds with accurate synchionization.- It should
be remembered that, due to the instantaneous nature of electronic flash,
exposure is determined by the diaphragm stop and light output selector
rather than by the shutter speed.
X-contact-Solenoid Operation allows tripping the shutter from the
Heiland 24-3 and, similar battery cases equipped with trigger switches.
Synchronization is, however, accomplished by the built-in X-contacts; the
solenoid being -used only to trip the shutter. It is also possible by this
method of operation to trip the shutter and the Strobonar from a distance
using the Heiland $-r0 Remote Control Cord. Connections should be
made as outlined above, in addition to a cord from the solenoid to the
"tripper or extension" outlet in the battery case.
It is possible to utilize one or more additional Strobonars as extension
units by use of either the Heiland Fotoeyes or a cube tap and connecting
cord {rorn the shutter to the shutter contact outlets in both Strobonars.
The latter method is not recommended for certain shutters as the shutter
contacts must carry an additional load with each additional unit. The
are considered satisfactory operating for two or more{ollowing shutters *X",Strobonars: Supermatic Rapax ooX", Alphax and Prontor, Klio, "X",

from the prirnary Strobonar is passed through the shutter contacts and
as many units as desired may be used with no harm to the contacts.
CAUTION:
. The Unitized Chassis of the Strobonar IV should never be removed
as the unit stores dangerous amounts of energy in the voltage range of
1000 volts, and direct contact with this stored energy could be lethal. The
unit is equipped with a safety switch so that removal of the chassis will
short circuit the energy-storage capacitors and open all operating circuits,
but it is recommended that the chassis be removed only by Heiland dealers
or their service personnel. When the chassis has been removed, the unit
cannot be operated unless the safety switch is blocked.
The Strobonar should never be operated in atmosphere containing
explosive dust or vapors as flash tube operation may be accompanied by
sparking at switches or socket contacts, and serious consequences could
result from such operation.
LIGHT CONTROL:
Due to the extremely high light output of the Strobonar IV, a variable
output control has been incorporated into the control panel. Light output
can thus be regulated from 50Vo to I00% of the maximum with inter-
mediate settings calibrated in 5% gradations. Close-ups and/or wide
aperture shots are thus possible without the necessity of difiusers which
might be undesirable for certain types of work. All guide numbers listed
in this manual are for I00% of the available light output. When the selector
is set at 50Vo the guide number must be multiplied by a {actor of .7 or
| "I)' stop wider aperture used; when set at 75/6 the factor will be .87
or L/z "{" stop wider aperture.
GUIDE NUMBERS AND LIGHT CHARACTERISTICS
The Heiland Strobonar IV produces more efiective light than any
other portable electronic flash unit ever designed. The distribution of the
Iight is extremely even over the area included by normal focal length lenses.
The Strobonar is used much like conventional flash except that ex-
posure time is determined by the duration of the flash (1/1000 of a second)
rather than by the shutter speed. Exposure is, therefore, controlled by
the diaphragm setting on the camera and by the variable output selector
on the Strobonar.
Extended development is recommended for most films exposed with
electronic flash, not to increase guide numbers, though this is a result, but
rather to increase contrast and detail in the negative. Highlights do not
block up and no excessive grain will result from this procedure with most
films and the manufacturers' recommendations should normally be fol-

lowed. Eastman Kodak suggests the use of its DK-60a developer for its
films and Ansco suggests the use of its Permadol developer. These two
developers do not give excessive grain or contrast when used with the
Strobonar.
The Strobonar IV at last makes possible action color at reasonable
distances. Its amazing light output combined with the even illumination
and the favorable color temperature of the Strobonar make the Strobo-
nar IV the ideal unit for almost all types of color work. The color tem-
perature of the light emitted by the Strobonar (About 7000" Kelvin) is
very close to that of daylight and daylight type color film may be used
with no color correction necessary. Some photographers prefer slightly
warmer tones than those produced by the Strobonar in which case a filter
such as the 81 C, or that recommended by the manufacturer, may be of
value.
Listed below are suggested guide numbers for the Strobonar IV under
the average conditions described above.
50Vo over--or extended-development '(LL/z X the development recom-
mended by the film manufacturer) is recommended for the reasons discussed
under "DEVELOPMENT". This extended development, for the purpose oI
gaining contrast, results in a slightly higher guide number. Most fine-grain
developers cause a definite loss of film speed. For this reason, guide num-
bers are shown (for black and white films) for "Fine-Grain," "Normal"
and "Extended" Development.

Using the guide numbers given above, the approximate oof" stop setting
is found by dividing the guide nurnber by the distance in feet between
the Strobonar lamp and the subject. For example, using Isopan cut film
and development A, at a distance of 30 feet between camera and subject
with a guide number of 450 the "f" stop would be 15; the nearest marked
"f" stop to this would l:e f./I6. When working outdoors with no reflecting
backgrounds, the guide numher is lower than those given above. Conversely,
working indoors with light-colored or white walls as reflecting backgrounds,
the guide numbers will be higher than those given above. In general,
there is more latitude in choice of guide numbers for black and white
film than for color film where light values are more critical. To determine
a personal exposure guide number, select a subject 20 {eet away in a mod-
erately sized room. Make one negative at each of the following aperatures:
I/8, II, 16, 22, and 32. Develop all of these negatives under carefully
controlled conditions and select the best one. If the best one was taken
at I/22, the guide number is 20x22, or 440. The same system is used for
color except that the test photographs are made at a distance of 10 feet,
and aperatures of I/4, 5.6,8, II, and 16 are used.

BATTERIES
The Strobonar IV is supplied with two Willard ER-11-2 Storage Bat-
teries which are shipped dry and must be filled and given an initial charge
before using. In the dry condition the batteries will keep several years
without deteriorating. Therefore, if you do not intend using your Stro-
bonar immediately, do not fill and charge the batteries. The batteries
must, however, be filled and charged before the Strobonar can be operated
either on "LINE" or "BATTERY."
Raise the spring clip and slide the battery compartment door away
from the Strobonar. Remove and discard the portions of tape covering
the vents on the batteries. Unscrew the small red filler cap on the top
of each battery (a coin will serve as a screwdriver) and fill each battery
to the bottom of the float channel visible through the windows on the
side of the Strobonar. It is recommended that the batteries be removed for
this initial filling; see note on page ll for removal of batteries. After filling,
coat terminals with vaseline to prevent corrosion. Let the batteries stand
Ior 4 to I0 hours so that the acid can soak into the dry plates and lining,
then add more acid if the liquid level has dropped below the bottom of the
channel. After the initial filling and 24-hour charge, all lurther additions
to bring the liquid level up are made only with distilled 'water. Do not use
city tap water as it may contain chemicals which will harm the batteries.
The distilled water may be purchased in any drug store or battery station.
The battery condition is indicated by a colored charge indicator visible
in the float channel of each battery. This channel may be partially filled
with acid by tipping down the battery end of the Strobonar. The battery
charge may then be read by noting whether or not the indicator floats.
The indicator will float if the battery charge is above approximately 50/o
and charging of the batteries should continue approximately 4 hours a{ter
the indicator begins to float. It is not necessary or desirable to allow the
battery to become {ully discharged before recharging. It may be recharged
at any time that a discharged condition is shown by the red charge indicator.
To recharge, use the 12 {oot cord supplied with the Strobonar IV connect-
ing it to the recessed outlet on the left side of the Strobonar and to an
outlet supplying 105 to 125 volts 50 to 60 cycle AC. A{ter these connec-
tions have been made, the switch should be moved to the "CHARGE"
position. The amber jewel opposite the "CHARGE" position will then glow
indicating that current is reaching the charging circuit of the Strobonar.
Charging time will vary, but generally, a fully discharged battery may
be completely recharged overnight. When a battery is completely dead
or the supply line voltage is below 115 volts, the recharging time may be
more than 12 hours. Charging may be safely continued for several hours
after the red indicator is floating I horvever persistent overcharging will
eventually damage the batteries. Normally batteries should be charged
lor 4 hours after the indicator rises.

Make certain the red battery lead is attached to the "positive" termi-
nal of the right hand battery and the black lead t,r the "negative" terminal
of the other battery. The jump lead should then connect the remaining
positive and negative tertninals. Improper connection of battery terminals
while charging will result in damage to the batteries.
The hydrogen gas generated while charging batteries is explosive. Do
not bring open flame near batteries while being charged. Do not tamper
with connections while the battery is being charged; this could produce a
spark which would ignite the escaping hydrogen.
NOTE: If it is necessary to remove the batteries for cleaning, replacing
or checking, this may be accomplished by lo.rsening the two captive screws
located on each side of the left end of the Strobonar capacitor case near the
battery compartment door. The end cover of the Strobonar may then be re-
moved by sliding the top of the cover away from the Strobonar, then sliding
the cover downward, away from the two Iocating pins present on the under
side of the Strobonar.
The cover is replaced by reversing the process. It is recommended
that the line cord be removed and the unit turned to "OFF" before remov-
ing the end cover. No danger is involved in removing this cover and no
high voltage leads or terminals are exposed. The unitized chassis of the
Strobonar which is now partially visible should not, hou;eaer, be rernoued.

INSTRUCTIONS
for use and operation o{
FOTOEYE, MODEL HR.ll PHOTOELECTRIC TRIPPER FOR
STROBONAR IV
The Heiland Fotoeye, Model HR-fl is designed to flash the Strobonar
IV as a slave unit when light of sufficient intensity falls on the photoelectric
surface of the tube. There is no decrease in light output of either unit
when using the Fotoeye. The Fotoeye will flash a Strobonar repeatedly
without the conventional necessity of replacing flash bulbs or making any
adjustments.- The Fotoeye cable connector is plugged into the indicated outlet on
the top of the Strobonar and is polarized automatically by 1!e plug or theFotoeye may be plugged into the shutter outlet if Model HR-llA is used.
The placement of the Strobonar is a matter of choice for lighting efiects
desired and the Fotoeye may be mounted in any position which will receive
sufficient light from the master source to activate the slave unit. A cord
permits mounting the Fotoeye in the beam o{ t}re master unit-while placing
ih" l"*p of the ilave unit elsewhere. A tripod socket in the Fotoeye {acili-
tates convenient mounting on a standard tripod head or with the Heiland
Fotoclamp. The Fotoeye will trigger the Strobonar by direct or indirect
light of Jufficient intensity and the shield should be rotated allowing the
miximum amount of light from the master source to enter the window in
the shield. The master flash may be any unit that produces sufficient illumi-
nation to fire the Strobonar by the Fotoeye: a Strobonar or conventional
flash bulb may thus be used as a master source. A Strobonar IV will trigger
the slave at 60 feet and may be used in any reasonable lighting arrange'
ment; an example being shown in the figure on this page.
I3View original page 15Page 16 · Read text
www.butkus.us
-il=tihtA- oENvER
The room reflectivity affects distance and placements; therefore,-the
best means of determining if the slave is functioning properly is to flash
the master source without attempting to expose the film.
It is necessary to allow the Strobonar with attached Fotoeye to charge 20 seconds after the neon indicator shows that the Strobonar is fully
charged. This additional time is required to charge a condenser that is in
the Fotoeye. The Strobonar may be operated from lI5 volts AC or from
the batterles which are incorporated into the unit. The master unit is the
only unit that is necessary to be fired directly by the camera shutter as
the slaves are fired from the light of the master'
The operating precautions that should be observed are as follows: If
the tube of the Fotoeye is removed from its socket, the tube, when replaced,
should be seated completely. The tube shield with the tube properly seated
should be capable only of being rotated; the Fotoeye will usually fire the
Strobonar if the glass envelope of the tube is touched by hand through
the window. The Fotoeye will also fire the Strobonar if the Strobonar is
{ully- charged when the Fotoeye is inserted into the shutter contact outlet.
The light patrern provided by the Strobonars may be determined by
direct addition of the values at all points of same physical position as shown
in the Strobonar instruction manual, page 9. Test shots with different "f"
stops may be necessary to determine proper exposure in initial stages of use. - The delay of the Fotoeye is only a few millionths of a second; there-
fore, photographically it can be considered negligihle.
The Heiland Strobonar I with the Model HR-7 Fotoeye provides a well
balanced sidelighting unit for use with the Strobonar IV. Again, there is
an increase in total light output from each additional unit.
STROBONAR IV EXTENSION NIODEL HR-T8
The Model HR-18 extension lamp provides a very convenient fill in or
sidelighting unit for the Strobonar IV. It is equipped with a 20' cable and
a removable tube with tripod socket which has been incorporated into the
base, permitting mounting on standard tripod heads or on the Heiland
Fotoclamp. The extension lamp may be mounted on a Heiland 24'3 Battery
Case or similar unit.
The extension outlet of the Strobonar is covered with a safety cap
which is lifted straight up to remove. The Strobonar cannot be operated
unless either the safety cap or the extension plug is in place. This assures
absolute sa{ety since no high voltage terminal is at any time exposed.
Identical controls are present on both the camera lamp and the exten'
sion lamp in order that the Strobonar may be operated from either lamp.
The time required for the neon indicator on the extension to glow may_vary
slightly from the indicator on the camera lamp but the difierence will be
so slight that it may be ignored. The light output of the Strobonar is
dividecl between the two lamps when using the extension and the guide
numbers used should be changed accordingly.
