mtu301 Owner’s Manual Page 1 of 6 mtu301 Owner’s Manual Cover: SpectraPulse® Ultra Wideband Wireless Microphone System mtu301 Body‐pack Transmitter Set‐up and Operation Inside: This device complies with Part 15 of the FCC rules. Operation is subject to the condition that device does not cause harmful interference. This device complies with INDUSTRY CANADA R.S.S. 220 en conformite avec IC:RSS‐220/CNR220 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. Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate ra dio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is unlikely to cause harmful interference. However, if the equipment does cause harmful interference, the user will be require d to correct the interference at own expense. CAUTION! Electrical shock can result from removal of SpectraPulse® components' covers. Refer servicing to qualified service personnel. No user‐serviceable parts inside. Do not expose to rain or moisture. The circuits inside the SpectraPulse® components have been precisely adjusted for optimum performance and compliance with federal regulations. Do not attempt to open the rcu104 Receiver Coordinator Unit, drm141 Digital Receiver Module (main assembly), aci707 Audio Control Interface, mtu101 Boundary Microphone Transmitter, mtu201 XLR Desk Stand Transmitter, mtu301 Body‐pack Transmitter, or cei007 Charger Encryption Interface. 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. 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. Please note that your SpectraPulse® system operates in a frequency band in a way which may make its use subject to certain FCC and other regulatory agency restrictions and licensing requirements. No changes or modifications may be made to this equipment except by the expressly approved responsible party for compliance. Changes or modifi cations could void the user’s authority to operate the mtu301 Owner’s Manual Page 2 of 6 equip ment, and will also void Audio‐Technica warranty coverage. For further information, Please contact your local office of the FCC as applicable. Battery precautions  Each mtu301 Body‐pack Transmitter is powered by 2 AA batteries: AA 1.5V alkaline batteries (included) or rechargeable SANYO brand AA Nickel Metal Hydride.  When using rechargeable batteries, always use rechargeable AA NiMH batteries.  Rechargeable batteries must be charged before initial use or after prolonged non‐use.  When inserting batteries into the mtu301, observe correct polarity as marked.  Do not use a leaking battery. If battery leakage occurs, avoid contact with skin. If skin contact occurs, immediately wash the affected skin area thor oughly with soap and water. If battery leakage comes into contact with your eyes, immediately flush with water and seek medical attention.  Do not expose the batteries to fire. Do not heat, deform, solder, disassemble or modify.  Do not peel off or damage the outer tube of a battery.  If batteries become damaged, dispose of properly.  Please recycle rechargeable batteries.  Do not use these batteries together with dry cells, other types of batteries, new and old batteries together, or batteries with different charge levels. Note: This SpectraPulse® system is approved for indoor use only. Note: See Sp ectraPulse® Owner’s Manual for full system specifications.
