    • Underneath the plugs are two small screws that can be removed with a small Phillips screwdriver.

    • The screws will need to be pried out after unscrewing them due to their size.

    • Take care not to lose the screws as they are small and have a tendency to roll.

    • The outer cover is now secured with seven tabs: one large tab (marked in red) and seven smaller tabs (marked in orange).

    • To begin removing the outer cover, start by prying the large tab up with a flat object.

    • See next slide for details for smaller tabs.

    • Continue to pry each smaller tab up, taking care not to break the tabs.

    • If disaster strikes and a tab is broken, the outer casing can still be put back on assuming the majority of the tabs are still intact.
