I Mount Unit
@ The PS200 is fixed on the accessory clip of
   any hot shoe (direct contact) type cameras,
   which makes automatic electrical contact. To
   smoothly mount, push the lower end of the unit
    into the hot shoe with fingers from the unit's
   .back.
@ To remove, push back the lower end of the unit
   from the  f ront side (opposite direction)   .





I   Alkaline Battsriss
Afkaline batteries are highly recommended for
electronic flash unit.
The increased number of flashes as well as long
shelf life makes the alkaline battery more econo-
mical to use.

 o The PS2OO synchronizes at all shutter  speedsi
    with any camera when the camera is set at "X"I
    contact.
O lf an E E camera without shutter speed indica-
    tion is used, set the camera  to the  f lash
     position.
 o  lf a focal plane shutter camera is used, the
   PS200 synchronizes at all shutter speeds slower
    than L/60 sec. or L/L25 sec., depending on the
   camera in use.
 * Be sure the camera is set at "X" contact or
    flash position on automatic cameras.

 I Exposure
 F/stop Galculation
o To determine proper exposure tor your flash
   pictures, first measure the flash-to-subject
   distance and refer to the chart on the unit by
        f inding the F/stop that corresponds to   f ilm
   speed and distance.   '.   For example, when a filrn of speed ASA25 is
                                            (11 ft),   .andused, the aperture would be t/2at 3.5m
   "              f /4 at L.7m (5.5 ft).

I Daylight Synchronization        -   .
 When the subject is illuminated from the opposite
 side of the camera (i. e. backlight), or the subject
 is against a bright window, or there is a sharp
 contrast between the subject and surroundings,
  f lash is effective for better pictures.
.The exposure is based on the daylight, and decided
 by the film speed and distance to the sirbject by
 using the GN chart on unit (see the table above).
 For this use, the camera must have an adjustable
 aperture and shutter speed control.
 With the P5200 you can adjust the daylight-flash
 relationship by changing the shutter speed,  f or
 electronic flash exposure at given distance is
 controlled by the  f /stop only. Changing the exposure
  f rom t/ll  at l/L25 to   f /16 at L/6O will give the
 same exposure as far as daylight is concerned but
 will reduce the exposure from the flash.
        (to be continued)

Exposure calculation begins with determination of
the exposure for the daylight; then measure the
distance from the flash to the subject. This
distance gives an f/stop, on which depends a proper
shutter speed. For instance, when the exposure is
t/5.6 at L/25O with ASA80 film, measure the
distance to the subject. lf the distance is 2m, you
can obtain   f /8  f rom the GN table provided. Then
you can adjust the shutter speed to L/L25.
O In focal plane shutter cameras the shutter speed
   should be set at l/60 sec. or below "X".

  G a utionI
The PS2O0 is to be used only bn camera with hot shoe.
Remove the batteries from the compartment  if the unit is being kept unused
for a long period. Avoid moisture, rain and sea water. When the batteries
are replaced, replace both batteries. Do not leave the unit in a high tempe-
rature above 50"C (L22" F) and if used below freezing point the unit should
be warmed up before use.
