® Manual Zoom Operation
To set the flash coverage angle
manually, press the zoom button.
When the zoom button is pressed,
the manual zoom indicator EJZoom
and the ZOOM indicator both
appear in the display. Each press
of the zoom button changes the
coverage angle in the following
cycle:
CD Zoom 34 mm -4 El Zoom 38 mm -4 E) Zoom 35 mm -4 El Zoom 53 mm

Be careful to select a setting that is equal to or less than the focal length of the
lens mounted on the camera. If you select a setting that is larger than the focal
length of the lens, the resulting photograph will be dark around the edges.
@ Using the Wide Pane!
By pulling out the wide panel and
letting it swing down to cover the
front of the flash head as shown in
the diagram, the flash can be
used to cover super-wide-angle
focal lengths as short as 18mm.
• The zoom button does not function
when the wide panel is in use.
• The wide panel should only be used
when the flash head is in the normal
(straight ahead) or 7° downward
position.
If the flash head is set to a bounce
position while the wide panel is
being used, both bounced flash
and direct flash may illuminate the
subject, creating an unnatural
effect. If this occurs, the entire
LCD panel blinks as a warning to
retract the wide panel.
<*
Be careful not to use excessive force when pulling out the wide panel.
□ I
• If the wide panel accidentally breaks loose from the flash unit, you will not be
able to operate the zoom button. If this occurs, operation of the zoom button
can be restored using the following procedure:
• While simultaneously pressing
both the flash mode button and the
zoom button, slide the main switch
from O to I , and then to the SE
position.
• This will restore the zoom button
operation, but the bounce indicator
will continue to blink in the display.
To repair the wide panel, take the
flash to your nearest Canon
service station.
(Display after zoom operation is
restored.)
