to your nearest Canon Service Center.
Problem Probable Cause Corrective Measures
The image is not clear. The lens is dirty. Use a blower brush to
remove dust, etc., from the
lens surface. Then use a
soft, dry cloth to wipe the
lens gently.
The width of the binoculars
does not suit the width
between your eyes.
Adjust the width of the
binoculars
(see step 4).
The diopter has not been
properly set.
Adjust the diopter
(see step 5).
The binoculars are not
properly focused.
Focus the binoculars
(see step 6).
The Image Stabilizer does
not operate.
There are no batteries
loaded.
Load batteries having
enough power.
When the Image Stabilizer
button is pressed, the lamp
does not light.
If the lamp does not light, it
means the batteries are
exhausted. Replace the
batteries with new ones.
The battery power is low. Even if the lamp lights, the
Image Stabilizer may not
operate if the batteries are
exhausted. Replace the
batteries with new ones.
When the binoculars are
shaken severely while the
Image Stabilizer is operating,
there is a strange noise.
The batteries are exhausted. Replace the batteries with
new ones.
There are air bubbles in the
lens.
Air bubbles may form in the
lens when the atmospheric
pressure is low in airborne
airplanes or on high
mountains. This is not a
abnormality.
The air bubbles will usually
disappear after about a
week, depending on the
atmospheric pressure and
operating conditions.
