  • Page 4 IR Sensors are designed to ‘see’ IR from any direction, allowing uninterrupted presentations. The CRS-101 System is easy to install and operate. Once set up, it will be ready for class every day. One important point: Just as students need sleep to re-charge, the microphone batteries need to be kept at peak performance levels as well, so it is important to re-charge the batteries before each use.

  • Page 13: Installation

    Figure 12. Typical Classroom Application INSTALLATION CRS-CASE The CRS-CASE can be wall or shelf mounted. It should be located in a central location that allows the IR Sensors to be equally spread in the classroom for optimum visibility to the microphones. Consideration should also be given to locating the CRS-CASE in close proximity to any audio source that will be connected to the Line In, such as a CD/DVD Player, Projector, Computer, VCR, Cable, Satellite, etc.
  • Page 14 Wall Mount The CRS-CASE has two screw keyholes on the Bottom Panel that allow it to be secured to a wall or cabinet. (Figure 2) Whenever possible, the screws for the keyholes should be secured to a wood panel instead of drywall to avoid having the screws work loose over time after repeated use of the CRS. If use of a wood panel is not possible or desirable, use screw anchors to secure the mounting screws to the drywall.
  • Page 15 Figure 14. Typical CRS System Connections CONNECTIONS The CRS-101 System requires only a few simple connections and sets up in minutes. The only required connections are the IR Sensors, Speakers and Power Cord. Connecting an optional audio source such as a CD/DVD Player, VCR, Computer, Projector, Cable, Satellite, etc is also simple using standard RCA- RCA audio patch cables.
