Set your camera lens to the f-stop indicated above that colored wedge on 
the Calculator Dial.

Switch on the flash unit. After the green Ready Light glows, fire the flash 
by pushing the Open Flash Button (1). If the flash exposure is adequate, 
the green Sufficient Light Indicator (10) will glow for about 2 seconds 
immediately after firing the flash. If it doesn’t light up, do one of the 
followings: set your flash and camera to an automatic mode that uses a 
wider f-stop opening; or, decrease the flash-to-subject distance.

Note: The Sufficient Light Indicator is for use in any of the four 
Automatic Modes and will not light if the Mode Selector Dial on the 
Sensor is set on manual “M” or if the Sensor is not connected to the 
flash.

The Sufficient Light Indicator will, however, also light up when the Mode 
Selector is set to one of the fractional Vari-Power positions. This is of NO 
SIGNIFICANCE and should be disregarded.

Attaching the Flash to the Camera

Move the Mounting Foot Lock Lever (14) all the way to the left (unlock 
position). Insert the Mounting Foot (15) into the accessory shoe of your 
camera. Move the lever to the right until it clicks into the “LOCK” position.

Your flash has a built-in hot shoe contact. If your camera does not have a hot 
shoe, connect the Shutter Cord (29) to the flash Shutter Cord Socket (16) and 
to your camera’s “X” sync terminal. (Refer to your camera instructions for 
specific information regarding your camera’s flash synchronization.)

Shooting Automatically

As you select a wider lens opening (a smaller f/number), you increase the 
amount of light entering the lens, thereby increases the flash range and the 
number of flashes per battery set. You’ll also benefit from faster recycling time.

Therefore, always try to select the auto mode that provides the greatest flash 
range. If your subject distance is well within the flash range selected, all is 
better. For example: your subject distance is 10 feet, your lens is a 50mm f2.0 
or faster, and you are using ASA / ISO 100. The flash unit Calculator Dial
