Power requirements

Pull the silicon rubber boot off of the unit by starting at
one end and pulling off towards the other end. On the
back side you will see the battery compartment. Slide
battery compartment cover off towards bottom end of
unit to reveal the 9V battery compartment. Insert a fresh
9V battery, make sure the wires are routed around the
battery. (If they are under or on top of the battery the
door may not close properly) You are ready to go. Do
not run this unit off of any power source other than a
9V battery. Wall adapters are electrically noisy, as
are vehicle electrical systems.
