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.
4. After checking the batteries,
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.
