X2's proprietary digital technology provides superior fidelity while the XDS95’s "stomp-box" style receiver houses a micro-processor that selects the digital data stream from among the four internally mounted Q-diversity™ antennas to eliminate dropouts and interference including DTV. You’ll enjoy the sound and performance of a direct wire connection free from compander ICs and the associated 'pumping' and 'breathing' that squashes your tone, and other problems associated with analog wireless technology. Operating the system is unlike any wireless you've tried before. Simply connect the transmitter to the source via the 1/8" threaded-collar locking connector and the "stomp-box" style receiver to your amplifier, mixer or pedal-board. Then power up making sure the transmitter and receiver are set to the same channel. That's it. You're ready to go! No knobs to adjust and no antennas to loose or break mean you're up and running in the time it would take to connect a cable. About the XDS95 Digital Wireless System All of this sound and performance is provided to you with an incredible feature set including: • 24-bit digital converters yield 117 dB dynamic range to capture your most expressive performances • Frequency Clear™ UHF Digital - a proprietary digital signal on a 900 MHz UHF carrier for freedom from multipathing and interference, including DTV • Five user-selectable channels (all five are fully compatible for simultaneous use) • Auto-DigiScan™ to confidently select an open channel • Frequency response all the way down to 20 Hz for truly thundering lows • Stereo 1/4" output for instrument and full-bandwidth or 'tuner out' applications • Five segment LED display (battery status, link status, audio level, RF level and channel) With the XDS95 Digital UHF Wireless System you'll have the freedom and sound to deliver your most expressive performance every time without any hassles or complicated setup procedures. To familiarize you with your new digital wireless system, we suggest that you read through this entire operation manual. System Components System includes: • XDR1 Digital UHF Receiver • XDT1 Digital UHF Transmitter • 2 9v Alkaline Batteries • 1/4” to 1/8” locking connector instrument cable Optional Accessories: • Power supply for XDR1 Introduction to the XDS95 Digital UHF Wireless 2 LED Display • See system setup on page 5. 1/4” Mono/Stereo Output • See system setup on page 5.

LEDs will cycle blue-red-blue on power up sequence.Once unit is powered on the unit will display current channel number with a blue LED and battery life with a red led by continuously toggling between the two LEDs. As the user inputs audio into the unit the LEDs automatically become an audio level indictor where blue LEDs are displayed from left to right as the audio level increases. LED #5 will light red during audio display if the units input reaches a maximum level. After a few seconds pause in audio input the unit switches back to channel/battery display mode. Channel Selection There are 5 different frequency channels which you can choose to transmit and receive data, they are labeled 1-5 on both transmitter and receiver. In order to operate on any one of these channels, you must have both the transmitter and receiver on the same channel number. In order to change the transmit frequency push the channel button, the unit will then increment and display the channel number with a blue LED each time the user presses the button down. Continue this until the desired channel number is reached. The unit will then go back to the toggling LED mode to display battery life and channel number. Transmitter Battery Metering The battery is displayed on the tranmitter as follows: LED #5 (furthest to the right looking at the front of the unit) means 5hrs or greater of battery life remaining. As the battery expires the unit will change the red leds to #4 for 4hrs, #3 for 3hrs, etc.. Once the unit has less than 1hr left of battery life the #1 LED will then blink at a high rate until the battery expires. This alerts the user to the need of battery replacement. Power Down Procedure To turn the unit off press and hold the on/off switch until the LEDs flash a red/blue alternating pattern then release the on/off button. The unit will then power down. all LEDs off indicate power down is complete. Connecting the System Plug your instrument into the transmitter with the provided cable. Next, connect the output of the receiver to the input of your effects pedal, amplifier, recording device, etc.. When using a standard 1/4” (mon…

We have requested that the schematic diagrams for the XDT1 Transmitter and XDR1 Receiver required to be submitted with this application be withheld from public review. This application contains detailed block diagrams, schematic diagrams, and a detailed theory of operation submitted to the FCC for review. The information within this application contains propriety information (trade secrets) regarding the circuit operation and capabilities specific values of components, circuit design and system architecture which are the results of our extensive investment in research and development. Without the disclosed information, competitive organizations would take considerable more time to asses and develop a workable competitive product. Since this is a new product in an existing market, we believe that is these documents are disclosed to our competitors, it would harm our ability to compete in this market. We therefore formally request that the materials contained in this envelope be kept strictly confidential and not made available for inspection by another party, except on a need to know basis for the sole purpose of the certification process.

X2 Digital Wireless Transmitter XDT1 CFR Title 47, Part 15, Subpart C MET Report: EMCS20866-FCC247 © 2006, MET Laboratories, Inc. Electromagnetic Compatibility Criteria for Intentional Radiators § 15.247(b) Peak Power Output and RF Exposure RF Exposure Requirements: §1.1307(b)(1) and §1.1307(b)(2): Systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy levels in excess of the Commission’s guidelines. RF Radiation Exposure Limit: §1.1310: As specified in this section, the Maximum Permissible Exposure (MPE) Limit shall be used to evaluate the environmental impact of human exposure to radiofrequency (RF) radiation as specified in Sec. 1.1307(b), except in the case of portable devices which shall be evaluated according to the provisions of Sec. 2.1093 of this chapter. MPE Limit Calculation: EUT’s operating frequencies @ 902-928 MHz ; highest conducted power = 10.03dBm (peak) therefore, Limit for Uncontrolled exposure: 0.6 mW/cm 2 or 6 W/m 2 EUT maximum antenna gain = -12 dBi. Equation from page 18 of OET 65, Edition 97-01 S = PG / 4πR 2 or R = √PG / 4πS where, P = Power Input to antenna (10.06mW) G = Antenna Gain (0.063 numeric) S = 10.06*0.063/ (4*3.14*20.0 2 ) = (0.633 / 5024) = 0.00125 mW/cm 2
