• 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.
