WM Watertight Transmitter and Remote Controls With Digital Hybrid Wireless ® Technology INSTRUCTION MANUAL Rio Rancho, NM, USA www.lectrosonics.com Fill in for your records: Serial Number: Purchase Date: US Patent 7,225,135 WM LECTROSONICS, INC. 2 Watertight Transmitter Rio Rancho, NM 3 Introduction The WM transmitter is designed to resist damage when used in wet or dusty conditions and also offer a compre- hensive feature set that makes it equally at home in film and television production and on stage. A solid machined aluminum housing with a corrosion re- sistant finish hosts dual battery compartments, a mois- ture sealed control panel with backlit LCD and enlarged membrane switches. Recessed seats for the O-rings in the battery caps and input jack allow the caps and mic connector to be tightened securely without excessive deformation of the O-rings. The antenna is made of an extremely durable, multi- strand alloy that will withstand heavy abuse. It is mount- ed with a compression sealed strain relief that prevents dust and moisture from entering the housing. As the first stage in the signal processing chain, the input preamp section includes very high quality, low noise components with a wide range of gain adjust- ment in 1 dB increments and a DSP-controlled input limiter. Dual color LEDs on the control panel accurately indicate audio input level for precise gain adjustment. Easily accessed screens on the LCD simplify setup and adjustments. Output power is adjustable to provide either extended operating range or extended battery life as needed for the application. The Digital Hybrid Wireless ® design (US Patent 7,225,135) combines 24-bit digital audio with analog FM resulting in a system that has the same operating range as analog systems, the same spectral efficiency as analog systems, the same long battery life as analog systems, plus the excellent audio fidelity typical of pure digital systems. The DSP-based design works with all Digital Hybrid receivers, and is backward compatible for use with Lectrosonics 200 Series, 100 Series, IFB receivers and some other brands of analog wireless receivers. Consumer Alert for US Users - FCC Order DA 10-92 Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this micro- phone system without a license is subject to certain restrictions: the system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless mi- crophone systems, and these rules are subject to change. For more information, call the FCC at 1-888- CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCC’s wireless microphone website at www.fcc.gov/cgb/wirelessmicrophones. To operate wireless microphone systems at power greater than 50mW, you must qualify as a Part 74 user and be licensed. If you qualify and wish to apply for a license go to: http://www.fcc.gov/Forms/Form601/601.html Table of Contents Introduction ...........................................................................3 General Technical Description ............................................4 Servo Bias Input..................................................................4 No Pre-Emphasis/De-Emphasis .........................................4 Low Frequency Roll-Off ......................................................4 Input Limiter ........................................................................4 Signal Encoding and Pilot Tone ..........................................5 Microprocessor Control .......................................................5 Compatibility Modes ............................................................5 Control Panel ......................................................................5 Wide-Band Deviation ..........................................................5 Variable Power Output ........................................................5 Battery Operation ................................................................5 Frequency Blocks ................................................................5 Circulator/Isolator ................................................................5 Controls and Functions .......................................................6 LCD Screen ........................................................................6 Power LED ..........................................................................6 Audio Input Jack ..................................................................6 Battery Compartment and Thumb Screw ............................6 Modulation LEDs .................................................................6 AUDIO Button .....................................................................6 FREQ Button .......................................................................6 Up/Down Arrows .................................................................6 Antenna ...............................................................................6 About Batteries .....................................................................7 Battery Compartments .........................................................7 Attaching and Removing the Microphone ..........................7 Operating Instructions .........................................................8 Power Up and Boot Sequence ............................................8 Power Down ........................................................................8 Standby Mode .....................................................................8 Compatibility, Output Power, Bias Voltage (phantom power) and LCD Backlight ..............................................................8 Audio LF Roll-off and Gain ..................................................9 Frequency Selection ....................................................…

Federal Communications Commission 849 NW State Road 45 Equipment Approval Services Newberry, FL 32669 Applicant: Lectrosonics, Inc. 581 Laser Road Rio Rancho, NM 87124 Re: Confidentiality for submittal information regarding FCC ID number DBZWMM PRODUCT: Wireless Microphone transmitter operating under part 74H Dear Sirs: Lectrosonics, Inc. requests that the material in the Parts List, Schematics, Block Diagram, and Operational Description be withheld from public disclosure pursuant to Sections 0.457 and 0.459 of the Commission’s Rules following grant of the application. In support of this request, Lectrosonics, Inc. submits the following. Permanent Confidential files Block Diagram Conf BlkDia WMM.pdf Parts List Conf PartList WMM.pdf Operational Description Conf OpDes WMM.pdf Schematics Conf Schem WMM1.pdf Schematics Conf Schem WMM2.pdf 1. Identification of the specific information for which confidential treatment is sought: The materials set fourth in the Operational Description, Parts List, 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: DBZWMM 3. Explanation of the degree to which the information is commercial or financial, or contains a trade secret or is privileged: This material includes a detailed theory of operation, circuit diagrams, (schematic diagrams) and detail Parts List. As such, this material is treated as highly confidential business information. ROGERS LABS, INC. 4405 West 259 th Terrace Louisburg, KS 66053 (913) 837-3214 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 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 Lectrosonics, Inc.’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 Lectrosonics, Inc. 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 Lectrosonics, Inc. 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 this 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 could be used for more than a decade in some cases. 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. Should you require any further information, please contact the undersigned. Thank you for your consideration in this matter. Sincerely, Scot Rogers
