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. Thse limits are designed to provide reasonable protection
against hmful interference in a residential installation. This
ment enerates, uses and can radiate radio frequency
y and, f not installed and used in accordance with the
inructions, may cause harmful 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:
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 prevnt
condensation in this case, first put the lens ito n
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.
• Reorient or relocate the receiving antenna.
• 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.

than normal shooting, so fewer shots can be
taken if you use the function.
This function provides optimal image stabilization
depending on shooting conditions (such as
shooting still subjects and following shots).
¡
¡Wen shooting a still subject, it compensates for
caera shake in all directions.
¡It compensates for vertical camera shake during
following shots in a horizontal direction, and
compensates for horizontal camera shake
during following shots in a vertical direction.
¡When you use a tripod, the Image Stabilizer
should be turned off to save battery power.
