FBRLCK-EIResponse Keypad Transceiver

Fleetwood Group Inc. FCC ID: FBRLCK-EI Page 1 of 2 File Name: EINK_Manual.doc Date: 6/15/2004 eInstruction cpsRF® Response System User Manual Model LCB100-E1 Base and LCK-E1 Keypad Frequency 2.4 GHz The eInstruction cpsRF Model LCK–E1 keypad is a wireless portable device that along with a base unit Model LCB100-EI makes it possible for a number of people to participate interactively in a class situation. The product accomplishes this by sending keypad switch closure information from the keypad to the base unit employing a wireless transceiver to receive the keypad signal. These signals are processed by the base unit and delivered to a host computer which allows the responses to be stored, analyzed and if desired displayed on a video projector for feedback to the group showing the results of their participation. The cpsRF keypad is housed in a translucent blue plastic enclosure similar in appearance to a small TV remote control device. It is powered by 2 AA battery cells, eliminating external wires or connections. The keypad uses a membrane switch panel for numeric entry and an LCD display for entry display to the user. The system operates on the 2.4 GHz frequency band using frequency hopping spread spectrum. In Canada, to prevent radio interference to any licensed service sharing this band, this device is intended to be operated indoors and away from windows to provide maximum shielding. Equipment (or its transmit antenna) that is installed outdoors is subject to licensing. System Setup 1. Unpack the cpsRF base unit and set it on a table or available surface in the vicinity of where the cpsRF keypads will be used. 2. Plug the USB DC power/data cable into an available USB port on a PC; plug the other end into the USB port on the cpsRF base. 3. Open the carrying case containing the response keypads and distribute them to the participants. 4. Turn on the computer and start the application software to control the base unit to poll for keypad responses. The application software will have its own instructions for using the system. Operation 1. Instruct the participants on the usage of the response keypads and procedure for responding. 2. Ask a question and/or send prompts from the base unit for keypad LCD display and allow enough time (at least 10 seconds) for all participants to respond. A self pace testing mode is also available. 3. Observe the results on the screen and optionally save the results for later analysis if desired. 4. Proceed and repeat the process for the next question. 5. Continue until all questions are completed. 6. Analyze the responses for the period and run printouts if desired. Fleetwood Group Inc. FCC ID: FBRLCK-EI Page 2 of 2 File Name: EINK_Manual.doc Date: 6/15/2004 System Shutdown 1. Turn off the power to the computer. 2. Unplug the USB cable from the computer and store it in its carrying case. 3. Store the cpsRF base in the carrying case. 4. Collect the cpsRF keypads and return them to the carrying case. 5. The system is now ready for transporting.

Box 1259 Holland, Michigan 49422-1259 Product: FHSS eInstruction Keypad portable Transceiver Model: LCK-EI Applicable Rules: 47CFR Part 15.247 Pursuant to 47CFR Part 1.1307(b), 47CFR Part 2.1093(c), and 47CFR Part 2.1093(c) this transmitting device, compliant to 47CFR Part 15.247, is categorically excluded from evaluation regarding the Maximum Permissible Exposure of RF energy. In addition and as evidence of compliance to the RF exposure guidelines: This device was measured to have a field strength level of 100dBuV/m peak at distance of 3 meters. 103.1BuV/m is 0.143V/m field strength. [ antilog(103.1/20) / 1000000 = 0.143 ] A field strength of 0.143V/m at 3meters suggests an EIRP of 6mW (0.006W). [refer to formula 2 below.] Supplement C to OET Bulletin 65 indicates a device of EIRP < 0.3W is not expected to exceed MPE limits and special instructions and warnings are not be necessary. Formula 2: Equivalent Isotropically Radiated Power PG = (E*d) 2 30 E = antilog(FS(dBuV/m)∕ 20 ) ∕ 1000000 d = 3 meter
