the serial number (1).

>.
 Remove the battery from the camera.
 Apply the label as shown in the
illustration (on the side with no electrical
contacts).
o Do not apply the label on any part other than as shown in the illustration in
step 2. Otherwise, the misplaced label may make it diffi cult to insert the battery
or impossible to turn on the power.
o When you use Battery Grip BG-E14 (sold separately), the label may peel off
as you repeatedly insert and remove the battery into the battery magazine. If it
peels off , apply a new label.
