The present invention prevents unauthorized access and modifications to programs and non-executable files, particularly a dialer program, stored on a personal computer system by providing a protected storage area on a hard drive of the PC wherein access to the protected storage area is controlled by the owneruser of the PC. A first indication that a first source device from the plurality of source devices has become active is received at the wireless home entertainment hub. The fluorescent lamp retaining member allows one retained lamp unit to rotate relative to the other retained lamp unit adjacent thereto, and so retains the lamp units adjacent to each other that the bundling members and conductive members are arranged alternately after one lamp unit has been rotated. The position indicator receives the position detecting signals and transmits position indicating signals indicating a position.
