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 radio 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 required 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.

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 thoroughly 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.
