It is loaded with advanced operating features that will simplify and enhance the operation of your scoreboard system. Some of the features include: ? Large, bright and easy to read dot matrix LED display. ? Lithium battery powered memory will maintain all of the scoreboard information when turned off, unplugged or after a power failure. Under normal conditions the battery will last in excess of 10 years so you won’t have to worry about replacing it. We recommend storing the control in a cool, dry place because extreme heat will shorten the life of the battery. Even if the battery is no longer functional, you can still operate the scoreboard(s); however the control no longer remembers or stores Bookmarks. ? Five programmable Bookmarks. This feature allows you to set the control now for future basketball, football, track, volleyball, wrestling, baseball, hockey, soccer, in-line hockey and swimming games. Simply change the overlay to the sport you desire and select the correct single digit Bookmark number and you are ready to play. ? An interval timer and horn (primarily used in junior hockey). ? Ten different time out timers, all programmable for different times with optional warning horn and an option to display the selected time on the scoreboard timer. ? Tenth second displayed on the scoreboard timer during the last minute when counting down. ? The alternate TIME ON and TIME OFF keys are on the control keyboard. These keys are provided in case your remote hand-held time switch is lost, stolen, broken or you simply wish not to use it. When the remote hand-held time switch is plugged into the control it disables the alternate TIME ON and TIME OFF keys. ? Set the Chronometer (time of day) on the scoreboard(s) clock by simply pressing the CHRONOMETER button on the control keyboard. The chronometer will keep accurate time even after disconnecting the control. 6622-BT 6-17-04 Page 3 Start Up Procedure The traveling display prompts you to ENTER YOUR MODEL CODE, START WHERE TURNED OFF LAST or USE A BOOKMARK.

June 25, 2004 Timco Engineering Inc. 849 NW State Road 45 Newberry, FL 32669 Office of Engineering and Technology Federal Communications Commission Columbia, MD 21046 Applicant: Nevco Scoreboard Company 301 East Harris Avenue P.O. Box 609 Greenville, IL 62246-0609 Re: Confidentiality for submittal information regarding FCC ID number PLH-ZW4 PRODUCT: Spread Spectrum Frequency Hopping Transceiver operating in the 902-928 MHz frequency band under part 15.247 and low power transmitter operating under 15.249. Dear Sirs: Nevco Scoreboard Company requests that the material in the Block diagram, Schematics, and Operational Description be withheld from public disclosure in accordance with Section 0.459 of the Commissions Rules, 47 C.F.R. 0.459 (1998), following grant of the application. In support of this request, Nevco Scoreboard Company submits the following: 1. Identification of the specific information for which confidential treatment is sought: The materials set fourth in the Operational Description, Block Diagram, and Schematics, which are segregated from the non-confidential exhibits of the application, are those for which confidentiality is sought. 2. Identification of the Commission proceeding in which the information was submitted or a description of the circumstances giving rise to the submission: The proceeding is that involving the application for equipment authorization (certification) under FCC ID No: PLH-ZW4 3. Explanation of the degree to which the information is commercial or financial, or contains a trade secret or is privileged: ROGERS LABS, INC. 4405 West 259 th Terrace Louisburg, KS 66053 This material includes a detailed theory of operation and circuit diagrams, (schematic diagrams). As such, this material is treated as highly confidential business information. 4. Explanation of the degree to which the information concerns a service that is subject to competition: The material for which confidentiality is sought is employed in the design and manufacture of this low power transmitting equipment that is offered on a highly competitive basis. Customers for this equipment have a variety of competing sources. 5. Explanation of how disclosure of the information could result in substantial competitive harm: Disclosure would, in effect, give away the fruits of the labors of Nevco Scoreboard Company’s engineering personnel, who have designed the equipment and the manufacturing process. Disclosure would also offer competitors additional unwarranted insight into the state of the product development, thereby allowing competitors an advantage, not available to Nevco Scoreboard Company 6. Identification of any measures taken by the submitting party to prevent unauthorized disclosure: The information for which confidential treatment is sought is kept confidential by Nevco Scoreboard Company and not made available to third parties except pursuant to non-disclosure agreements. 7. Identification of whether the information is available to the public and the extent of any previous disclosure of the information to third parties: To the knowledge of those preparing this application, the information has not been disclosed publicly heretofore. While the general theory of operation of this equipment has been the subject of numerous disclosures in industry and standards groups as well as in rule making proceedings of the FCC, the protection sought is narrowly drawn and pertains to certain specific implementations of the low power and spread spectrum radio technology. 8. Justification of the period during which the submitting party asserts that the material should not be available for public disclosure: This material should not be disclosed for at least 25 years. While improvements in design are made relatively frequently, disclosure of the design information would lead to insights into both design and manufacturing techniques that could have an adverse competitive effect for many years to come. This equipment is designed for commercial, industrial, and governmental applications. As such, unlike most consumer equipment, this equipment will be used for more than a decade in some cases. Moreover, this equipment will be used in revenue collection and secure access control applications (e.g. volume and pressurized piping facilities). As such, it is important that the design not be made available to unauthorized persons who might attempt to use knowledge of the design to compromise the applications for which the equipment will be employed. 9. Any other information that the party seeking confidential treatment believes may be useful in assessing whether its request for confidentiality should be granted: See item 8 above. Note that the equipment for which approval is being sought will be employed in applications that inherently place a premium on security. Should you require any further information, please contact the undersigned. Thank you for your consideration in this matter. Sincerely, Scot Rogers

The ZW4 is a low power transmitter operating in one of two modes, either as a frequency hopping spread spectrum transmitter or a low power device under 15.249 operating in the frequency band of 902 MHz to 928 MHz with 0.03 watts or less of output power. Per table 1 of 1.1307, paragraphs 1.1310 and 2.1091 of CFR 47, evaluation for this device is as follows. Due to the location of the antenna, normal operating conditions and use, the unit will satisfy the requirements for RF Exposure. Calculations are made here for completeness. Operating configuration and exposure conditions The unit is placed on a scoreboard or table top positioned at least 20 cm from all operators. For master control operation, the unit is placed on a table top and used by a score keeper to update the remote score board. The score board unit is typically placed on top of a remote scoreboard, receives information from the master score controller and updates the scoreboard display. Calculated general population / uncontrolled exposure Per 1.1310, the requirement for power density in general population/uncontrolled exposure is f/1500, which equates to 0.6 mW/cm 2 calculated for 915 MHz. This calculated amount to be averaged over a time period of 30 minutes. The inherent design and use of this product places the antenna at a distance grater than the 20 cm used for this calculation. The 20 cm distance was used to show compliance only. S = PG/(4piR 2 )? Where S = power density in mw/cm 2 ; P = input power to antenna in mw; G = power gain of antenna; and R = distance from antenna in cm; pi = 3.14159. For a minimum distance of 20 centimeters and 0.03 watts (30 mW) operation with the supplied antenna with a maximum gain of 1.64, S is calculated as 0.0098 mw/cm 2 . S = 30(1.64)(4pi (20) 2 ) = 9.788E-3 mw/cm 2 This is well within the 0.6 mW/cm 2 limit prescribed for general population/uncontrolled exposure as prescribed by CFR 47 paragraph 1.1310. Note: the unit meets the requirement for general population at a minimum distance of 2.75 cm.
