Pairing TroubleshootingIf your OPTIMAX unit does not operate correctly, please use the following guide to determine the cause. If, after following this guide,your unit still does not operate, please contact your supplier beforereturning it: Symptom WarrantyYour OPTIMAX is warranted for 24 months from date of purchase against defects in manufacture or component failure. The unit isdesigned for domestic, educational, commercial and light industrialapplications. Use outside these areas will invalidate the warranty.Unauthorised repair or modification, mechanical abuse, immersionin any liquid or connection to any equipment other than a host computer will invalidate the warranty. Your OPTIMAX uses a unique addressing system to ensure that there is no interference from neighbouring units. The Trackball transmitsits data along with an address, and the Receiver unit only respondsto that address.To function correctly, both the Trackball and Receiver unit must use thesame address. The process of negotiating an address is called 'Pairing'and once learned, both the Trackball and Receiver units will retain theinformation even when powered off or when changing the battery.Your OPTIMAX is supplied already paired but it may occasionally be necessary to go through the process again- for instance if a newReceiver is to be used with an existing Trackball unit or in theunlikely event that one half 'forgets' the address.To Pair the units, use the following procedure:1. Remove the battery compartment cover. 2. Place the Trackball within one metre (three feet) of the Receiver unit. 3. Press the button on the underside of the Receiver unit. The LED should flash. 4. Within 10 seconds, briefly press the button inside the battery compartment. It is not necessary to spin the ball. 5. After a short period the LED should light steadily for 5 seconds and cursor operation should resume. Replace the battery compartment cover. 6. If the LED stops flashing after around 15 seconds and does not light steadily, repeat the process from (3). If it is still not successful, please refer to the Troubleshooting section. Possible cause/ Remedy No cursor movement-LED remains lit -Units are not Paired. Follow procedure in Pairing section. No cursor movement-LED is not lit. -Check USB or PS2 connection to computer.-Units may not be correctly Paired. Follow procedure in Pairing section. Cursor movement iserratic or sporadic. -Battery may be flat- replace.-Place Receiver unit away from metal objects and in view of Trackball operating area. -Out of range. Move Trackball closer to Receiver. -Interference from other radio equipment. Change channels by rebooting computer from cold. Units will not Pair- LEDis extinguished after 15seconds and cursordoes not move. -Ensure that Trackball is held within one metre (one yard) of Receiver while Pairing. -Check battery- replace if flat. OPTIMAX is the very first, wireless trackball specifically designed for users with motor skill difficulties.With an operating range in excess of 10 metres OPTIMAX is ideally suited for use in team/group sessions, or classroomsettings, to ensure the participation of all.Lightweight and robustly constructed with no mechanicalwearing parts, OPTIMAX can be used as either a desktop or hand-held unit.Optical technology ensures precise cursor control and silky-smooth ball movement, and the bi-directional radio link provides interference free operation.

Federal Communications CommissionFCC 07-56 Before the Federal Communications Commission Washington, D.C. 20554 In the Matter of Modifications of Parts 2 and 15 of the Commission’s Rules for unlicensed devices and equipment approval ) ) ) ) ) ET Docket No. 03-201 SECOND REPORT AND ORDER Adopted: April 17, 2007 Released: April 23, 2007 By the Commission: I.INTRODUCTION 1.By this action, we amend our rules to providefor more efficient equipment authorization of both existing modular transmitter devices and emerging partitioned (or “split”)modular transmitter devices. These rule changeswill benefit manufacturers by allowinggreater flexibility incertifying equipmentandprovidingrelief from the need to obtain a new equipment authorization each time the same transmitter is installed in a different final product. Therule changes will also enable manufacturers to develop more flexible and more advanced unlicensed transmitter technologies.We further find that modular transmitter devices authorized in accordance with the revised equipment authorization procedures will not pose any increased risk of interference to other radio operations. II.BACKGROUND 2.Part 15 of the Commission’s rules governs the operation of unlicensed radio-frequency devices. As a general condition of operation, Part 15 devices may not cause harmful interference to authorized radio services and must accept any interference that they receive. 1 In recent years, there has been a significant increase in the number and types of devices operating under the Part 15 rules. Examples of common Part 15 devices include cordless phones, computers, wireless baby monitors, and garage door openers. Such devices are widely used in everyday consumer functions. Moreover, the rapid growthof devices that followindustrystandards, such as IEEE 802.11 and Bluetooth, promise to further increase both the number and variety of devices that will operate on an unlicensed basis. Overall, the Part 15 rules have been highly successful in fostering the development of new unlicensed devices while protecting authorized users of the radio spectrum from harmful interference. Millions of Part 15 devices operate within the current rules without any significant interference issues. 3.In recent years, manufacturers have developed Part 15 transmittermodules (or “single” modules) that can be incorporated into many different devices. These modules generally consist of a completely self-contained radio-frequency transmitter (transmission system) missing only an input signal source and a powersource to make it functional. Once the modules are authorized by the Commission under itscertification procedure, they may be incorporated into a number of host devices such as personal computers (PCs)or personal digital assistants (PDAs), which have been separately authorized. 2 The 1 47 C.F.R. § 15.5. 2 The Commission’s equipment certification procedure is set forth in Sections 2.907, 2.927, 2.931, and Sections 2.1031 through 2.1060, 47 C.F.R. §§ 2.907, 2.927, 2.931 and 2.1031-2.1060. Federal Communications CommissionFCC 07-56 2 completed product generally is not subject to requirements for further certification by the Commission. Therefore, modular transmitters save manufacturers the time and any related expenses that would be incurred if a new equipment authorization were needed for the same transmitter when it is installed in a new device. 4.This efficiency is a result of the June 26, 2000 Public Noticewhich the Commission released in response to manufacturers’ request for guidance about the conditions under which approvals for Part 15 modular transmitters may be granted. 3 The Public Noticedetailed eight criteria that must be met in order for the Commission to grant certification for modular transmitters. The Public Noticeonly addressed deviceswhere all of the radio frequency components were contained completely within the module itself. 5.A new class of “split” modular devices is now under development. 4 These transmitters consist of two basic components: the “radio front end” or radio elements and the “firmware” or hardware on which the software that controls the radio operation resides. The radio front end and firmware can each be self-contained units. In split modular devices the radio front end is generally a stand-alone unit, while the firmware may either be a stand-alone unit or may be collocated within a device on a host system. A further partitioning is also possible by removing the local oscillator and tuning capacitors of the antenna from the radio front end. The separation of modular devices into these components will provide manufacturers the flexibility to design a larger variety of modular systems by mixing and matching individual components. 6.On September 10, 2003, the Commission adopted a Notice of Proposed Rulemaking(Notice) inwhich it, inter alia,proposed to clarify the equipment authorization requirements for modular transmitters. 5 Sixteen parties filed comments in response to the Notice’sproposals forPart 15unlicensed transmitter module approvals.These parties arelisted in Appendix C. III.DISCUSSION 7.In this Second Report and Orderwe codify the Public Noticerequirements for approving modular transmitters, with certain modifications. We also adoptrequirements for the approval of split moduletransmitters, including a requirement that only parts of a split modulethat have been approved in a single application for equipment authorization may operatetogether. Further, we allow manufacturers the flexibility to demonstrate alternative methods in the application for equipment authorization to ensure that amodular transmitter will meetall the applicable Part 15 requirements under the operating conditions in which itwill be used. We find that the increased flexibility adopted herein will facilitatethe approval processfor modular transmittersandprovide relief from the need to obtain a new equipment authorization each time the same transmitter is installed in a diffe…
