2. The AE - 1 PROGRAM' s battery check circuit
not only tells you whether the battery is good
but also how good it is. First make sure the
main switch is on "A." Then press the bat-
tery check button for two to three seconds . If
the battery's power is sufficient. the camera
will emit about six or more "beeps" per
second . If the battery is weak and needs re-
placing, the camera will beep at the slower
rate of about three " beeps" or fewer per
second.
3. The battery is exhausted if, after pressing the
battery check button for about three
seconds, no sound is emitted . Replace the
battery with a new one.
