1999, Shure Incorporated Printed in U.S.A. WARNING! USING THIS SYSTEM AT EXCESSIVE VOLUMES CAN CAUSE PERMANENT HEARING DAMAGE. USE AS LOW A VOLUME AS POSSIBLE. In order to use this system safely, avoid prolonged listening at excessive sound pressure levels. Please use the following guidelines established by the Occupational Safety Health Administration (OSHA) on maximum time exposure to sound pressure levels before hearing damage occurs. 90 dB SPL at 8 hours 95 dB SPL at 4 hours 100 dB SPL at 2 hours 105 dB SPL at 1 hour 110 dB SPL at 1 / 2 hour 115 dB SPL at 15 minutes 120 dB SPL — avoid or damage may occur It is difficult to measure the exact Sound Pressure Levels (SPL) present at the eardrum in live applications. In addition to the volume setting on the PSM, the SPL in the ear is affected by ambient sound from floor wedges or other devices. The isolation provided by the fit of quality earpieces is also an important factor in determining the SPL in the ear. Here are some general tips to follow in the use of this product to protect your ears from damage: 1. Turn up the volume control only far enough to hear properly. 2. Ringing in the ears may indicate that the gain levels are too high. Try lowering the gain levels. 3. Have your ears checked by an audiologist on a regular basis. If you experience wax buildup in your ears, stop using the system until an audiologist has examined your ears. 4. Wipe the ear molds with an antiseptic before and after use to avoid infections. Stop using the earphones if they are causing great discomfort or infection. This symbol indicates that dangerous voltage constituting a risk of electric shock is present within this unit.

Stereo pilot used as tone-key. 16. Timing circuitry for quiet operation. II Circuit Description Audio Section The PSM transmitter requires a line level input source, balanced or unbalanced entering via (1 /4)” plugs. If only one connector is plugged in the signal is applied to both left and right input sections. The input signal (left and/or right) is converted from a balanced to an unbalanced signal through an active network (U201, U301). The unbalanced signal then gets sent to the headphone amp as well it goes through a 15kHz brick wall low pass filter (FL201, FL301). So that any 19kHz information from the input does not confuse the receiver pilot-detection circuitry. The signal is then buffered, pre-emphasized (R219, C211), (R319, C311) and AC coupled into the compressor/limiter (NE571 U502A,B). The NE571 utilizes external amplifiers (U501A, B). The compander performs 2:1 logarithmic compression of the audio signal, which then feeds into U601, the stereo modulator. These two signals are “window” compared by U401 against fixed levels. If either signal exceeds these levels current is fed into the rectifying capacitors (C505, C515) thus lowering the gain on the compressor. The stereo modulator outputs both the stereo modulated signal, and a 19kHz tone to be used as a pilot. The pilot tone is filtered and adjusted for proper phase (L601). The pilot tone is then mixed with the modulated audio (U602A). The level of pilot relative to audio is adjusted with trimmer pot R608. The mixed signal passes through a switch (SW601) controlled by the microprocessor, which is used to eliminate “popping” when frequencies are changed. The LED ballistics are somewhere between peak and VU, with the intention of giving peak indication that is slow enough for the user to visually catch short transients. RF section Processed audio and pilot tone enter R35, an internal potentiometer that is adjusted for 35kHz deviation (100% modulation). The audio is then fed to the tuning voltage pin of the voltage Controlled oscillator (VCO), and modulates the carrier directly. The VCO is shielded to prevent external Rf fields from affecting its operation. Regulated 5vdc power is provided to ensure frequency stability. The VCO is capable of tuning from 722 to 746 MHz (UA- Model) and 800 to 863 MHz (M and K - Models) witha1to9volt tuning voltage range. At the output of the VCO the RF signal splits into two paths. The output of the VCO is coupled by C36 the frequency control pin of the synthesizer U29. The synthesizers internal circuitry divides the signal as necessary to the desired reference frequency. The synthesizer contains a quartz-controlled reference oscillator circuit operating 16Description: PSM 400 TRANSMITTER (722-863 Mhz)DRWG : P4T-7 Refer To Drawing NOS. 90-XXXX-11, P4T-3 Page 3 of 16 ISSRecord of Changes Made 1.Production Release Exp Dwg.

The output of the synthesizer is a series of current pulses, which are integrated by a passive loop filter to produce a control voltage signal. The control voltage signal is then connected to the VCO through amplifier U30A, which is used to isolate the PLL filter from the audio modulation signals the transmitter operates on eight selectable frequencies. Frequency selection is made via microprocessor U5 which interfaces with the user by means of switch SW20A. The VCO output is also coupled to a RF MMIC Q100 amplifier through a resistive pad.

The tests were performed according to the procedures of FCC as stated in Part 2 Subpart J, Equipment Authorization Procedures of the Code of Federal Regulations 47, by personnel of D.L.S. Electronic Systems, Inc. who are responsible to Donald L. Sweeney, Senior EMC Engineer. 3.0OBJECT The purpose of this series of tests was to determine if the test sample could meet the radio frequency emission requirements of the FCC "Rules and Regulations", Part 74, Subpart H, Sections 74.801 to 74.882 for Low Power Auxiliary Stations operating in the 720 to 806 MHz Frequency Band. 4.0TEST SET-UP All radiated emission tests were performed at D.L.S. Electronic Systems, Inc. The radiated tests were made with the test item placed on a wooden turntable located in the Test Room with the receive antenna placed one meter from the device under test. EMC Test ServicesReport No. 7627 1250 Peterson Drive, Wheeling, Illinois 60090, USA10/01/99 Page 8 5.0TEST EQUIPMENT (Bandwidths and Detector Function) All data was automatically plotted using peak detector function. This information was then used to determine the frequencies of maximum emissions. Manual measurements were performed on these frequencies using a peak detector function of the Analyzer with the bandwidths specified by the FCC. From 200 MHz to 1000 MHz a bandwidth of 100 kHz was used (except for Occupied Bandwidth), and above 1000 MHz, wide enough bandwidths were used, depending upon the test being made, to ensure proper measurement of the narrowband signal. A list of the equipment used can be found in Table 1. All equipment was calibrated per the instruction manuals supplied by the manufacturer. 6.0RF POWER OUTPUT - PART 2.1046 As stated in PART 74.861 (e-1), the output power should not exceed 250 milliwatts (24 dBm). The Wireless Personal Monitor System was tuned according to the tune-up procedures specified in Part 2.1033 (c-9), and adjusted for its maximum output power. The RF output power was measured in the open field, using the following test method: The radiated signal from the EUT was measured. The EUT was then substituted with a signal generator and a tuned dipole antenna. The output of the signal generator was increased until the level received by the tuned dipole equaled that of the previous measured from the EUT. Actual Measurements Taken: 85.6 dBuV Measured output of the transmitter +38.5dBuV Total system losses (Antenna, Pads & Cable) 124.10 dBuV which equals 0.05 watts LIMIT: Manufacturer's rated output power = 0.05 watts MARGIN: 0.25 watts - 0.05 watts = 0.20 watts NOTE: See the following pages for the graphs of the actual measurements made: EMC Test ServicesReport No. 7627 1250 Peterson Drive, Wheeling, Illinois 60090, USA10/01/9…
