a Safety Precautions
T
his device complies with Part 15 of the FCC Rules. Operation is
subject to the following two conditions: (1) This device may not
cause harmful interference, and (2) this device must accept any
interference received, including interference that may cause
undesired operation.
Do not make any changes or modifications to the equipment
unless otherwise specified in the instructions. If such changes or
modifications should be made, you could be required to stop
operation of the equipment.
This equipment has been tested and found to comply with the limits
for a class B digital device, pursuant to part 15 of the FCC Rules.
These lims are designed to provide reasonable protection against
harmful rference in a residential installation. This equipment
ates, ses and can radiate radio frequency energy and, if not
led and used in accordance with the instructions, may cause
hmful interference to radio communications.
However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful
interference to radio or television reception, which can be determined
by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
• Reorient or relocate the receiving antenna.
a Safety Precautions
• Do not look at the sun or a bright light source
through the lens or camera. Doing so could result
in loss of vision. Looking at the sun directly through
the lens is especially hazardous.
• Whether it is attached to the camera or not, do
not leave the lens under the sun without the
lens cap attached. This is to prevent the lens from
concentrating the sun’s rays, which could cause a
fire.
Handling Cautions
• If the lens is taken from a cold environment in
a warm one, condensation may develop on the
lens surface and internal parts. To preven
condensation in this case, first put the lens into an
airtight plastic bag before taking it from a cold to
warm environment. Then take out the lens after it
has warmed gradually. Do the same when taking
the lens from a warm environment into a cold one.
• Do not leave the lens in excessive heat such as in
a car in direct sunlight. High temperatures can
cause the lens to malfunction.
• Increase the separation between the equipment and receiver.
•
Consult the dealer or an experienced radio/TV technician for help.
This Class B digital apparatus complies with Canadian ICES-003.
a Shooting Precautions
If a very bright spotlight like a mercury lamp is
photographed in a dark place with this lens, a halo
of light may occasionally appear around the light
source because of the DO elements.

Tips on Using the Image Stabilizer
• The Image Stabilizer cannot compensate for a
blurred shot caused by a subject that moved.
• When you use a tripod, the Image Stabilizer
should be turned off to save battery power.
• The stabilizer is equally effective for hand-held
photography and photography with a monopod.
• The image stabilizer function also operates
when the lens is used with an Extension Tube
EF12 ll or EF25 ll.
• Pictures may look distorted after being taken
dpending on the camera, but this doesn't affect
oting.
•
Set the STABILIZER switch to
when you are
taking pictures using the Bulb setting (long
exposures). If the STABILIZER switch is set to
the image stabilizer function may introduce errors.
• The Image Stabilizer might not be fully effective
in the following cases:
• You shoot while riding on a bumpy road.
• You move the camera dramatically for a
panning shot in Mode 1.
• You shoot using techniques other than
following shots in Mode 2.
,
• If yu set the camera’s Custom Function to
change the assigned button to operate the AF,
the Image Stabilizer will operate when you press
the newly assigned AF button.
• The Image Stabilizer consumes more pwer
than normal shooting, so fewer shots cn be
taken if you use the function.
•
The image stabilizer operates for about two
seconds even when your finger is off the shutter
button. Do not remove the lens while the stabilizer
is in operation. This will cause a malfunction
