Example: You wish to photograph a subject 10 feet away and desire
moderately great depth of field. Using ASA film / ISO 100 and the Zoom /
Bounce Head in the NORM position, set the Mode Selector Dial to the
Blue position and set your camera lens to f8. Your automatic operating
range is from 2 to 15 feet (0.6-4.5 m) (photo A).
Slide the On-Off Switch to the RED “ON” position. Focus the camera. If
desired, test the exposure using the Sufficient Light Indicator (page 13).
Take the picture when the green Ready Light glows. Your flash unit will
automatically determine correct exposures without further adjustments as
long as you remain within the automatic range you have selected.

Zoom settings – If you wish to extend or retract the Zoom / Bounce Head to
the TELE or WIDE settings, this will not affect the operation of the automatic
sensing system of the flash. It will, however, alter your operating range and
flash light coverage (see Automatic f-stop Settings and Corresponding Ranges
in page 21).
Example: Using ISO 100 and the Zoom / Bounce Head in the TELE position,
set the Mode Selector Dial to the Blue position and your camera lens to f8.
Your automatic operating range is now from 2 to 18 feet, instead of 2 to 15 feet
as in the NORM position of step 6 above (see photo A and B for comparison).
On-Camera Bounce Flash
When the flash is set at 45
ﾟ, 60ﾟ, 75ﾟ and 90ﾟ, the light can be bounced off
the ceiling or other reflective surfaces to create a softer lighting. As a general
rule, set the tilt angle of the head so that the light is directed at the midpoint on
the ceiling between the flash and the subject.
Set your camera to the correct shutter speed for electronic flash. (Refer to
your camera instructions.)
If you have not already done so, set the Zoom / Bounce Head to the
NORM position and set the ISO or DIN film speed on the Calculator Dial.
After positioning your subject, tilt the Flash Head to the desired bounce
angle.
Select any one of the four automatic f-stops on the Calculator Dial that
provides the automatic operating range or depth of field you desire.
Turn the Mode Selector Dial on the Vari Sensor Module until the color
that corresponds to the f-stop you selected above appears in the window
on the side of the Vari Sensor Module.
