ABS, remote control or handheld case The new HR and HRP cases are very robust, elegant (oval) remote control cases that fit ergonomically and safely in the hand thanks to their fluted sides. The HRP case has a panel on the front, while the HR does not. The cases also differ in length. The HR and HRP cases have a recessed surface for accommodating membrane keyboards, are available in black and computer colours and have a closable 9 V battery compartment.
