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
