11. Lift the back panel off the unit, exposing the internal
components and set it aside.
12. Looking at the unit from behind, locate the flicker motor
on the left beside the circuit board. (Figure 4) Unplug
the motor wire connector from the circuit board and
unhook the wires from the retaining clip(s) on the bot-
tom panel.
13. Remove the flicker motor mounting bracket, by remov-
ing the 2 screws that attach to the bottom panel.
14. Grasp the flicker motor with the mounting bracket and
