Theproduct accomplishes this by sending keypad switch closure information from the keypad to abase unit which employs a wireless transceiver to receive the keypad signal. These signals areprocessed by the base unit and delivered to a host computer which allows the responses to bestored, analyzed and if desired displayed on a video projector for feedback to the groupshowing the results of their participation. As such, the product is very similar to anotherFleetwood product, the CRS1200. The Model CRS10000 adds to the Model CRS1200 byincorporating an 800 MHz wireless microphone circuit that allows a participant at a remotesite to speak into the keypad and communicate with an instructor through a phone lineconnection. This adds the dimension of allowing verbal interaction from a remote site with aninstructor.Description of the KeypadThe Reply Model CRS10000 Keypad is housed in a plastic enclosure similar in appearance toa calculator. It is powered by an internal 9 volt alkaline battery with no external wires orelectrical connections. The keypad uses a membrane switch panel for numeric entry and a 7segment LED display for entry display to the user. The keypad uses a synthesized transceivercompliant with FCC Part 15 Subpart B and C. An integrated microphone and talk requestbutton provide an audio function for use in multiple site applications. The wirelessmicrophone portion of the device is compliant with and approved under Part 74.Using the KeypadTo use a Reply® DL Keypad, a corresponding channel Reply® DL base unit must be activeand under control of an application running on a local or remote host computer.

When interrogated by the base via the 216 MHz link, the keypad sends the keyinformation to the base in a 10 millisecond duration signal from the 345 MHz transmitter.When the 216 MHz signal responds with an appropriate state of the acknowledge bit for thekeypad, the keypad turns back off and awaits the next key press. This sequence takes on theaverage between one and two seconds. If the keypad LED winks and comes back on, thesignal was not received by the base and the keypad will retry the next time it is interrogated(typically about 2.5 seconds). The keypad spends most of its time in a sleeping modeconserving the battery and allowing for thousands of transmissions.If a user wishes to talk to the instructor the user presses the “Talking Face” key on the keypad.This transmits the microphone request to the base unit and via a data modem on the base tothe host to notify the instructor. When the instructor is ready to take the request, an activationsignal is sent out via the data modem to the remote site base unit which in turn commands thekeypad to activate the microphone.In Case of DifficultyThe Reply® Model CRS10000 Keypads are built using the latest technology and highreliability components. There are very few things the keypad user can do wrong to cause afailure, but in the unlikely event responses are not being received by the base and passed on tothe personal computer, the next pages detail procedures that can help identify the source of theproblem:
