3. Turn on the Main Switch. If
the red Flash Ready Lamp
(located in the center of the
Flash Guide Disk) turns on in
a few seconds, the batteries are
properly loaded.

be sure to turn off the Main
Switch.
Note: If the Main Switch is left
on, the batteries will be exhausted
in a short time even if the flash is
not discharged.
Battery life
On manual flash, a new set of
alkaline-manganese batteries
will provide about 150 flashes
but it is always best to change
them as soon as they start to
show wear. If the recycle time
lags to 30-second or more, the
batteries should be considered
exhausted.
Be sure to change the four bat-
teries all at once and make
sure all four are of the same
brand and are new.
After you are through taking
pictures, always turn the Main
Switch off to save battery.
