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 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.

mode.  
¡The Image Stabilizer cannot compensate for a  
blurred shot caused by a subject that moved.  
The Image Stabilizer may not be fully effective if you shoot  
from a violently shaking vehicle or other transportation.  
¡The Image Stabilizer consumes more power  
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.
