Affixing the rubber feet to the Drive case
It is highly recommended you use the supplied rubber feet for
horizontal placement and stacking of Drives. The feet help keep
the Drive securely in place, and they also prevent the Drive case
from possibly scuffing your desktop.
1. Decide whether you want the Power-Data Light to be located on
the left or right side when the Drive is in the horizontal position,
and select the appropriate side on which to affix the feet.
. Remove one of the rubber feet from the
paper backing and carefully position the
foot inside one of the four oblong
indentations, with the adhesive
side down. Once the foot is
properly positioned, press
down firmly to secure it
in place. Repeat for the
other three feet.
