LOADING BATTERIES
Make sure the ON/OFF switch is in OFF position.
Slide open the battery cover and insert 2 x AA
batteries in the direction shown by the symbols in the
battery compartment. Close the battery cover.
Inserting batteries with the wrong polarity may cause
the batteries to overheat, leak, explode and/or
damage the flash. Switch the ON/OFF switch to the
ON position. The ready indicator will light within a
few seconds if the batteries are properly installed.
When you need to replace the batteries, be sure all
of the batteries are the same brand, type and

ATTACHING THE FLASH TO YOUR
CAMERA
The flash can be mounted directly onto camera’s hot
shoe socket. If hot shoe socket contacts on your
camera do not match the contacts on the foot of the
flash, do not mount the flash onto the camera. If the
contacts do not match, your camera or flash may be damaged. If you do not
have a hot shoe on your camera, the flash may be connected using the
synchro cord (included) to connect to the camera’s PC sync terminal.
USING THE FLASH
Switch the flash to the ON position. Refer to the Exposure Table on the back
of the flash, estimate the camera to subject distance and note the film speed
in order to get the correct camera lens aperture setting. The aperture can be
calculated using this formula:
Aperture (f) = guide number (GN) / flash to subject distance (m)
Example: Flash Used = FM650
Film speed: ISO 100; Flash to subject distance: 5.0m
The correct aperture should be f4.
