Decide how you want to arrange the battery pack, the phone jack and
the servomotor on the base plate. The arrangement shown allows room for
later installation of a switch, if desired. (If you do not use a switch,
it will be necessary to remove the batteries when the device is not in
use.)
When you are confident of the layout, remove the paper from the base
and attach the battery pack and the phone jack with double-sided foam
tape.
Also attach the motor with foam mounting tape.
