Do not affix the label on any part other than as shown in the illustration in
step 2. Otherwise, the misplaced label may make it difficult to insert the
battery or impossible to turn on the camera.
If you use Battery Grip BG-E11 (sold separately), the label may peel off
as you repeatedly insert and remove the battery. If it peels off, affix a new
label.
