First-Set charger voltage
 Your Honeywell Rapid Charge unit can be used to charge the built-in nickel cadmium batteries
 on either 115 volt AC (standard U.S.A.) or 230 volt AG (many European and other countries).
 Set the charger voltage selector on the bottom of your rapid charge unit to match the line
 voltage you will use. Use a ballpoint pen or similar object, position in the slots as shown, to
 set the voltage selector.
                                     GAUTION: The charger voltage selector must
                                      be set to the voltage you are using to prevent
                                     damage to your charger.
                            A wall outlet AC adapter may be necessary  in
                                 some countries to adapt the.two-prong plug
                                on your charger to the AC wall outlet. The
                                         adapter may vary from country-to-country or
                                               within a particular country.
Before you use your unit the first time
Gharge the nickel cadmium batteries for three hours and form the storage capacitor.
To charge, set the voltage selector as described above. Connect the charger as shown on
page 3 and set the Battery switch (10) to OFF.
To form the capacitor, set the Battery switch (10) to ON, and fire the flash about 5 times by
 pressing the Open Flash button (9). Wait about 30 seconds between flashes.
ilOIE; When operating the charger at 90 to 100 volts AC (Japan), set the Voltage Selector to 115V. The number
of flashes per minute ol charge wlll be lese than shown in the chart on page 7.

Use your unit frequently
Your Auto/Strobonar  thrives on frequent use. Use it often. lf you can't, charge the batteries
and form the capacitor as described on page 6 at least once very 30 days. lf you don't use
your 460 for several weeks, it is normal for the batteries to lose some of their charge and the
storage capacitor to deform. A deformed capacitor causes longer recycle time for the first
few flashes and less flashes per battery charge. lf you are in a hurry, form the storage capaci-
tor by using your Auto/Strobonar in your photographic situation, Just remember that your
recycle time will be longer for the first few flashes.
Battery Gharging
The Honeywell battery saving circuit lets you charge the batteries for weeks without damage.
It is good practice to charge the batteries after each use. Always recharge batteries  if the
ready light (14) takes 30 seconds or longer to turn on. Above all, try at least once every 30
days to charge the batteries.


The batteries degrade when they are not charged periodically or if they are stored at tem-
peratures above 95 degrees Fahrenheit (35 degrees Centigrade). Therefore, always charge
the'batteries for at least 24 hours if you are not getting the number of flashes listed in the
chart above. The 24-hour charge conditions the batteries for normal rapid charge use.
ALWAYS DTSCOwTVECT the charger  f rom your AutolStrobonar when you have completed charging. Thfs is requlred
to keep the batterles lrom discharging needlessly through the circuitry In thit charger.
AVOID STORTTVG On CHABCTNG your Strobonar at temperatures ln excess ot 95 degrees Fahrenheit (35 degrees
centigrade). 7o do so will cause the batteries to accept a limited charge in the times recommended (see page S).
To obtain normal battery operation again, charge tor at teast thrce hours at temperaturcs betow 95 degrees.
WARNING: Do not operate your AutolStrobonar it the ready light takes 30 secorrds or more to glow. To so do may
damage the batteiles. Charge the batterles and then opercte your AutolSttobonar,

Attaching to camera
 lf your camera has a built-in accessory shoe, mount your Strobonar to the accessory shoe and
tighten the knurled nut on the mounting shoe. Cameras equipped for cordless flash have a
 center contact in the accessory shoe. In this case, there is no need to connect the shutter cord
included with your 460.
 lf there is no contact in the accessory shoe, just connect the shutter cord by inserting the 100
jack into receptacle (8). Connect the end with the removable tip connector to the X-sync termi-
 nal of your camera. Tip connectors are available for a variety of cameras (see your dealer). A
standard PC (DlN)tip is supplied.
 lf your camera does not have an accessory shoe, use one of the many Honeywell brackets
available from your dealer.




Setting shutter speed
Use X-synchronization (zero delay).  lf your camera has a between-the-lens  shutter it will syn-
chronize at all speeds.  lf it has a focal plane shutter, it will synchronize only at slower speeds,
generally up to 1/60 second. Check your camera instruction manual.

    Taking pictures automatically

          1. Turn Calculator dial (11) until the ASA number of film is opposite the ASA index-  (12).
         2. Choose the f/stop that gives you the depth of field and/or range you want opposite one of
         the three symbols (a, O, A) on the outer ring of the Calculator (11). You have a choice of
         three stops for each different film speed. The maximum shooting range for each stop appearsrl      opposite the symbol
       EXAMPLE:  lf you are using a film speed of ASA 25 you can shoot at either a f/5.6 (2 to 10 feetj,t      or .6 to 3 meters), a t/3.5 (3 to 16 feet or .9 to 5 meters), or Lt/2.0 (4 to 28 feet or 1.2 to 8.5
         meters).
         3. Turn Selector (4) between its stops until the symbol opposite your selected stop on calcu-
          lator appears in the lower window of the selector. BE CAREFUL NOT TO FORCE SELECTOR
      AGAINST STOPS. THE TRIANGLE ( ) IS THE LIMIT WHEN ROTATED CLOCKWISE. THE
      MANUAL (M) IS THE LIMIT WHEN ROTATED COUNTERCLOCKWISE. IF YOU ARE AGAINST
       THE STOP,JUST FINDTHE SYMBOLYOU WANT BYTURNING IN THE OPPOSITE DIRECTION.
        4. Set your camera lens to your selected f/stop.
        5. Set Battery switch (10) to ON.
        6. Shoot your picture after the ready light (1a) comes on. Within the range of your selected
          f/stop, your subject will receive correct exposure automatically- with no -bothersome adjust-
        ments or calculations.

Taking pictures in manual mode using calculator
1. Turn the automatic Selector (4) counterclockwise  until Manual (M) appears in the lower
window of the Selector.
2. Turn Calculator (11) until ASA film speed is opposite ASA index (12).
3. Check the distance from the flash to your subject, using the camera range finder or some
other convenient method. Remember  it is flash-to-subject distance that counts, not camera-to-
subject distance.
4. Set the f/stop on your camera that appears opposite the flash-to-subject distance on the
calculator (11).
5. Switch the Battery switch (10) to ON and take your picture after the ready light comes on.
EXAMPLE:  lf you are using a film speed of ASA 25 with a flash-to-subject distance of 10 feet,
(3 meters) the proper f/stop to set on your camera is f/5.6.
NOTE: The calculator sca/e and the guide number are based on avercges calculated lor average size rooms with
light walls. lt you are taking pictures in a very large rcom ot out ol doors at night, you may need to increase the
exposure by one l/stop or more.
Accessory lens kit
The accessory lens kit (Cat. No.4301) adapts your Strobonar for various picture taking situa-
tions. This kit has regular and wide-angle UV and neutral density lenses. lt has a clear wide
angle lens which increases the angle of coverage of the 460 to include the field of view of a
35mm wide angle lens for use on 35mm cameras. The kit also has filters for use with photo
flood balanced film. The lenses can be fitted and removed in seconds.

Taking pictures in manual mode using
guide numbers
 1. Turn the automatic Selector (4) counterclockwise  until Manual (M) appears in the lower
window of the selector.
2. Find the guide number for the film speed you are using in the table below.
3. Determine the flash-to-subject distance.
4. Divide the guide number by the flash-to-subject distance to find your f/stop setting for
average exposure and set this f/stop on your camera.
5. Switch the Battery switch (10) to ON and take your picture after the ready light comes on.
EXAMPLE:  lf you are using a film speed of ASA 25 at a flash-to-subject distance of 10 feet
(3 meters) the proper f/stop to set on your camera is f/5.6 (56 divided by 10 or 17.1 divided
by 3). The nearest click stop on your camera is close enough for practical work.

EXAMPLE: Your camera is loaded with fast film (assume ASA 400). You desire to shoot at a
flash-to-subject distance of 7 feet (2.1 meters) and the smallest lens opening on your camera
is f/16. Using the guide number method, compute an f/stop ot t/32 (224 divided by 7 or
68.3 dividedby 2.1). Then set your camera at'f /16; install the ND ff2tiller (see page 10) and
the effective exposure is  f /32. Thus, the ND ft2 tilter reduces the intensity of your Strobonar
by 2 f/stops.

Tips for usrng your Auto/Strobonar

Move in close for tight shots or back away for long shots. You can do this without changlng
setting when operating automatically.
Try to llne up a group so that everyone is about the same distance from your Auto/Strobonar.
Try to keep your subject a few feet (about 1.5 meters) from the wall. This will keep the harsh
shadows out of your pictures.
For more pleasing results, try to have a light, bright color a few feet from your subject.
Avold shooting through doorways or against windows where objects close to your field of
view may reflect light into the sensor, causing incorrect exposure.
Bounce llash - Use manual mode for bounce flash. Remove flash from camera and allowabout two full stops more exposure to compensate for the light absorbed by the ceiling or
wall under average conditions.
Stop-Action - The fantastic speed of your Auto/Strobonar  (1 /70,000 to 1/3,000 second) is ex-cellent for such stop-action pictures as breaking a light bulb, hitting a golf ball, and bursting
a balloon. Creative pictures of this type require special techniques. Usually the camera shutter
 is set to "8" and a simple switch (made of aluminum  foil, paper clip or pieces of wire) is used
to fire the flash at the moment you desire to make the exposure. Be sure to photograph your
subject in a dark area and fire the flash when the shutter is open. For further information, write
Gustomer Services.

Outdoor use for fill-in light
Your Auto/Strobonar 460 may be used quite simply in manual mode as fill-in light when sun-
 light causes heavy side or front shadows. Just enough fill light should be used to soften the
shadows, so more detail can be seen in the shadow areas. Of course, too much fill light will
overpower the reflected sunlight and completely cancel the shadows. The amount of fill light
to use depends upon your personal preference. As a starting point, use one-half of a full flash
exposure for color film and one-fourth for black-and-white film.
The techniques of fill flash, although not complicated, are beyond the scope of this owner's
manual. lf you would like to explore this technique, write to Customer Services.
