Calculator Dial
The Calculator Dial (4) is a convenient built-in guide for determining flash
exposures. It is not electronically connected to the flash. After familiarizing
yourself with the meanings of the numbers and colors, you will find the dial a
very versatile tool. Under dim lighting conditions, press the Calculating Dial
Light Button (11) and the dial is illuminated.
Operation:
Set the Zoom / Bounce Flash Head to the NORM position.
Set the black arrow (19) of the Vari-Power Dial (inner ring of Calculator
Dial) to the FULL position (see photo A in Calculator Dial Illustrations,
page 19).
Set the ASA / DIN film speed.
To set the Calculator Dial for the ASA (ISO) or DIN number of the film you are
using, turn the outer edge of the dial until the appropriate number on the ASA or
DIN scale is opposite to the white Film Speed Indicator Arrow (5). If the ASA or
DIN number of your film is not on the Calculator Dial, use the film speed chart
shown below to find the film speed location and align that speed with the white
arrow.

Select auto operating mode.
There are four colored wedges (23) with trailing range lines on the
Calculator Dial. Each color represents an automatic operating mode
which corresponds to an automatic f-stop. Each mode takes into account
a combination of two things – the auto range and depth of field (greatest
sharpness in front and back of subject). Which colored mode you select
will depend on the combination you want.
Select the auto mode you want. The Calculator Dial will give you the
minimum and maximum auto range and correct f-stop setting for the auto
mode you’ve selected. To determine operating ranges of the selected
mode, look on the dial and find the colored wedge of the mode and the
range line that trails off from it. The number at the end of the line is the
