Problem
The Speedlite 220EX cannot be
detached from the camera.
The Speedlite 220EX does not
fire even when the shutter button
is pressed completely.
After turning on the Speedlite
220EX, the pilot lamp turns off
after a while.
When high-speed sync is used
with Type A cameras, the picture
is underexposed.
The subject looks blurred in the
picture.
Probable Cause
The hot shoe lock release has not
been slid to the right to release the
locking pin.
The Speedlite 220EX has not been
mounted properly on the hot shoe.
The hot shoe contacts are dirty.
The Speedlite 220EX mounting foot
contacts are dirty.
If the Speedlite 220EX is not used
for 90 sec., the power turns off auto-
matically to save battery power.
With high-speed sync, the Guide
Number changes depending on the
sync speed. A faster sync speed
reduces the flash range. If the sub-
ject is beyond the flash range,
underexposure results.
If the flash is used with the aperture-
priority AE mode in low light condi-
tions, a slow sync speed is set auto-
matically. A blurred picture may be
taken if the camera is handheld at a
slow shutter speed.

Solution
Slide the hot shoe release to
the right to release the locking
pin.
Mount the Speedlite 220EX
properly and securely on the
camera.
If the contacts are dirty, use a
clean cloth to wipe them clean-
ly.
Press the shutter button
halfway, or press the test firing
button.
Set the shutter speed so that
the desired flash range is
obtained.
Use of a tripod is recommended
at slow shutter speeds.
