Canon A-1 Repair Manual page 11

10
o The figures "2" and "10" mean that the self-timer
releases the shutter after a time lag of two and
10 seconds respectively.
o Press the shutter button only after closing the
eyepiece shutter, to block extraneous light.
The camera measures the light the instant before
ahutter release. (The AE-l measures before the
self-timer starts).
o After completing self-timer photography, return
the self-timer lever either to "A" or to "L".
(3) Cancelling the aelf-timer operation
o Return the self-timer lever to "L",
o Press the battery check button or set the dial
at "B" and take your finger off the button.
(4) Self-timer operation indicator
A red LED beside the shutter button keeps flashing
while the self-timer is in 'operation. When the self-
timer lever ia set to "10", the flashing frequency is
2 Hz until two aeconds befor e shutter release and
increases to 8 Hz after that time. When the self-
timer lever i. aet to "2", the LED flashes at 8 Hz
frequency.
This flashing helps the user to know approximately
when the ahutter will be released.
(5) Self-timer operation with the shutter button at "B"
If the self-timer is started with the ahutter speed
at "B", the camera will stop functioning the moment
your finger is taken off the shutter button. This
means that when the self-timer is in operation, it
will be cancelled. Since the self-timer will not
operate properl y without a locking cable release when
the shutter speed is set at "B", Canon has employed
a safety device like that. (By using a locking cable
release, the self-timer can be used at RB"..
Of course,
manual exposure calculation is necessary).
