8.0 Audible Beep Settings
Press the AUDIO Button B (Fig. 5) to provide an “audible ready confirmation”. A short beep will indicate
that the unit is ready to fire.
NOTE: When AUDIO Button
B (Fig. 5) is OFF, the modeling lamp will momentarily turn off when the flash
is fired and will come back on when ready.
9.0 Flash Output
The flash power output is variable over a 6 f-stops range from 1/32 to full in 1/10 f-stop increments using
the Flash Power Control
H (Fig.5). The power is displayed in an easy to use decimal form where each
whole number represents 1 f-stop. The control has a minimum setting of 1.0 and a maximum setting of
6.0. Pressing the button
H (Fig.5) will change the value by 0.1 f-stop (giving a total of 51 values). For
example, if the current value shown is 5.6, then to reduce the power by 1 f-stop just reduce the setting to
4.6. The following table shows the whole decimal numbers and equivalent fractional power ratio:
Display power Fractional equivalent
6.0 1(FULL)
5.0 1/2
4.0 1/4
3.0 1/8
2.0 1/16
