An electronic device includes a body, electronic components contained in the body, and two finger members. The two finger members movable relative to the body between an extended state and a collapsed state. In the extended state, the two finger members extend outward from the body for receipt by a mount of an external support. In the collapsed state, the two finger members are collapsed toward the body. In the extended state, the two finger members may extend parallel with each other for receipt in parallel slots of the mount of the external support.
