Canon 540EZ - Manual (Page 17)

Warning Indication
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.
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:
(Display after zoom operation is
restored.)
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 buttoh
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.
