Logos Av Com - Via Risorgimento, 22 - 48018 Faenza - Italy tel +39 0546 622 080 - fax +39 0546 622 090 - www.logosav.com Operating instructions The battery The voting keypad shall turn on by pressing any numerical key. As no "open" voting is occurring, the voting keypad shall turn off after a few seconds. Once the voting operations have started and you have to vote, you will see that the voting keypad, after pressing any key, will stay on for a longer time, i.e. for the whole duration of the voting operations. It shall turn off, automatically, only when the voting operations have finished. While the voting operations are "open", it is possible to change one's vote by pressing key C. The voting keypad shall turn off and you can enter your new vote. The voting keypad is fed by a 9 Volt alkali battery. The charge level of the battery can be checked by keeping to what follows. keep key C pressed and press (simultaneously) the Asterisk key; the red led shall blink and shall turn off after a few seconds: the battery is charged the red led is on: it is possible to vote, but the battery must be replaced within a short time the red led does not turn on: replace the battery by unscrewing the two screws behind the voting keypad.. When connecting and disconnecting the battery connector, make sure that the keyboard flat cable is not folded. Alkali batteries are more likely to discharge as a result of the passing of time than because of their usage for voting operations. It is therefore recommendable to replace them once a year. NOTE - This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates , uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: -- Reorient or relocate the receiving antenna. -- Increase the separation between the equipment and receiver. -- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. -- Consult the dealer or an experienced radio/TV technician for help. (FCC ID OM4 TLVKPD4K) CAUTION Changes or modifications not expressly approved by the manufacturer for compliance could void the user’s authority to operate the system.

Operational Description

Operational Description The P.C. software is used to communicate to the Televoter controller the kind of polling, the numbers of keyswitches enable, the numbers of voting keypads enable, and the numbers of the keyboard enable. The Televoter controller transmits the request of poll to the voting keypads and waits to the answer. This operation is made for every number of the voting keypads enable from the software of P.C. After receiving of all polls the Televoter controller transfers the polling to the P.C and goes to sleep mode. Its wake up is controlled from P.C when it needs to do a new polling. The voting keypads, after transmission of its data, close the transmitter. In this status the receiver is active.

The voting pad is composed of the following elements: a plastic container with antenna cover containing: - an electronic card with logic, transmit and receive sections (transceiver) and TX/RX antenna mounted (welded to PCB), - battery - Keyboard with 10 numeric keys (0-9) and 2 function keys. Each keypad has an identifying number from 1 to 4096. The pressing of a key records its reference number on internal memory. This equipment sends this number, identifying the pressed key, to the Televoter Controller (FCC ID: OM4 TLVUCT4K) when a voting session is opened, that is when the controller request data. The data is sent by air (radio TX mode), when the Controller carries out a polling operation on all present voters and calls up the identifying code of each voter. 1.2 Related Submittal(s)/Grant(s) FCC ID: OM4TLVUCT4K Test Report No. RD2000/009 FCC ID: OM4TLVKPD4K Date January 20 th , 2000 TÜV QSL 4/17 1.3 Tested System Details The FCC IDs for all equipment, plus descriptions of all cables used in the tested system (including inserted cards, which have grants) are: Model & Serial No. FCC IDDescriptionCable Descriptions US-KPD-4000 (1) s/n 0201 OM4TLVKPD4K Televoter Voting Keypad No cable provided Remotely connected to: US-UCT-4000 s/n EMC-99-0319 OM4TLVUCT4K Televoter controller Unshielded power cord Shielded signal cable Compaq Contura 420C s/n 7534HPE53700 CNT75MB2CCNotebookUnshielded power cord Shielded signal cables Series 2862 s/n E4532433329T NoneAC adapter for notebook Unshielded power cords DM 119 s/n 3031602 DYKDM119Printer, parallel I/FUnshielded power cord Shielded signal cable (1) EUT submitted for grant.
