Operation is subject to the condition that this device does not cause harmful interference. A copy of the declaration of conformity can be found on the internet at www.audio-technica.com. This device complies with INDUSTRY CANADA R.S.S. 210, en conformité avec IC: RSS-210/CNR210. Operation is subject to the following conditions: 1) This device may not cause harmful interference and 2) this device must accept any interference received, including interference which may cause undesired operation. Changes or modifications not expressly approved by Audio-Technica could void your authority to operate this equipment. CAUTION! Electrical shock can result from removal of the receiver cover. Refer servicing to qualified service personnel. No user- serviceable parts inside. Do not expose to rain or moisture. The circuits inside the receiver and transmitter have been precisely adjusted for optimum performance and compliance with federal regulations. Do not attempt to open the receiver or transmitter. To do so will void the warranty, and may cause improper operation. Notice to individuals with implanted cardiac pacemakers or AICD devices: Any source of RF (radio frequency) energy may interfere with normal functioning of the implanted device. All wireless microphones have low-power transmitters (less than 0.05 watts output) which are unlikely to cause difficulty, especially if they are at least a few inches away. However, since a “body-pack” mic transmitter typically is placed against the body, we suggest attaching it at the belt, rather than in a shirt pocket where it may be immediately adjacent to the medical device. Note also that any medical-device disruption will cease when the RF transmitting source is turned off. Please contact your physician or medical-device provider if you have any questions, or experience any problems with the use of this or any other RF equipment. Thank you for choosing an Audio-Technica professional wireless system. You have joined thousands of other satisfied customers who have chosen our products because of their quality, performance and reliability. This wireless microphone system is the successful result of years of design and manufacturing experience. Audio-Technica’s System 9 is a four-channel frequency-agile wireless system designed to provide rock-solid performance along with easy setup and clear, natural sound quality. Featuring stackable, contemporary styling, System 9 is available in handheld, headworn, guitar, lavalier and body-pack configurations. The system offers four compatible user-switchable channels in one of four available VHF frequencies (169.505, 170.245, 171.045, and 171.905 MHz). Each System 9 professional VHF wireless system includes a receiver and either a body-pack transmitter or a handheld microphone/ transmitter. ATW-901 UniPak ® body-pack transmitter systems include models pre-packaged with either an AT-GCW guitar cable (/G), a PRO 8HEcW headworn microphone (/H), a PRO 92cW headworn microphone (/H92), a PRO 92cW-TH headworn microphone (/H92-TH), or a lavalier mic (/L) for particular applications. All A-T Wireless Essentials ® microphones and cables, available separately, are pre-terminated for use with any ATW-901 system. Because System 9 packaging is designed to hold all versions of the system, some compartments in the carton may be intentionally left empty. The ATW-R900 receiver includes a switching power supply that automatically adapts to changes in mains voltage. The versatile ATW-T901 UniPak body-pack transmitter has both a high-impedance input for instruments, and a low-impedance input with bias connection for use with dynamic and electret condenser microphones. The ATW-T902 handheld transmitter features a unidirectional dynamic microphone element. Both the body-pack and handheld transmitters use internal AA batteries and have Power/Mute switches and input Trim (level) adjustments. Receiver Installation Location For best operation the receiver should be at least 3' (1 m) above the ground and at least 3' (1 m) away from a wall or metal surface to minimize reflections. Keep the receiver antennas away from noise sources such as digital equipment, motors, automobiles and neon lights, as well as away from large metal objects. In multi-channel systems, position receivers at least 3' (1 m) apart and keep operating transmitters at least 6' (2 m) from the receivers to help assure maximum RF performance. Output Connections There are two audio outputs on the back panel: balanced and unbalanced. Use shielded audio cable for the connection between the receiver and the mixer. If the input of the mixer is a 1 / 4 " jack, connect a cable from the 1 / 4 " unbalanced audio output on the back of the receiver housing to the mixer. If the input of the mixer is an XLR-type input, connect a cable from the balanced XLR-type audio output on the back panel to the mixer. Power Connection Connect the DC plug on the included AC power adapter to the DC power input on the back of the receiver. Secure the cord over the cord hook on the back of the receiver, to keep the plug from being detached by an accidental tug on the cord. Then plug the adapter into a standard 120 Volt 60 Hz AC power outlet. (Note that the receiver has no power Off/On switch. The receiver will be energized whenever the power adapter is connected and plugged into the AC outlet. Unplug the power supply from the AC outlet when the system is not in use — both for safety, and to conserve energy.) Antennas A novel “dipole” antenna system on the …

Applicable Standards ANSI/TIA 603-C:2004, FCC CFR 47 Parts 2 and 74, RSS- 123 Issue 1, Rev. 2 Applicant: AUDIO TECHNICA CORPORATION FCC ID: JFZT902 IC #: 1752B-T902 MODEL #: ATW-T902 REPORT: O:\A\AudioTechnica_JFZ\1975AUT12\Extra1975AUT12\1975AUT12TestReport.doc Page 6 of 16 TEST PROCEDURES Power Line Conducted Interference: The procedure used was ANSI/TIA 603-C: 2004 using a 50uH LISN. Both lines were observed with the UUT transmitting. The bandwidth of the spectrum analyzer was 10 kHz with an appropriate sweep speed. Bandwidth 20 dB: The measurements were made with the spectrum analyzer's resolution bandwidth (RBW) = 1 MHz and the video bandwidth (VBW) = 3 MHz and the span set as shown on plot. Power Output: For a device with a fixed antenna, RF power is measured as ERP as the antenna is permanently attached. The substitution method was used as described in ANSI/TIA-603-C: 2004. Antenna Conducted Emissions: The RBW = 100 kHz, VBW = 300 kHz and the span set to 10.0 MHz and the spectrum was scanned from 30 MHz to the 10 th Harmonic of the fundamental. Above 1 GHz the resolution bandwidth was 1 MHz and the VBW = 3 MHz and the span to 50 MHz. Radiation Interference: The test procedure used was ANSI/TIA 603-C: 200…
