The cam member 180 is used to rotate the first amount R1 along a first plane and the second amount R2 along a second plane, where the first amount R1 and the second amount R2 are distinct. For example, the first amount R1 may be ninety degrees and the second amount R2 may be ten degrees.
In the bottom open position BO, the electronic component 205 is accessible for repair or replacement. Once access to the electronic component 205 is not desired, the bottom handle 160 may be rotated from the bottom open position BO to the bottom closed position BC.
