Set-up and Operation

This device complies with part 15 of the CC Rules. Operation is subject to the condition that this device does not cause harmful interference.
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.
Notice to individuals with implanted cardiac pacemakers or AICD devices:
Any source of R (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 R 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 R equipment.
CAUTION! 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.
Warning: To prevent fire or shock hazard, do not expose this appliance to rain or moisture.
Attention: Pour prévenir feu ou choc électrique, ne pas exposé l'appareil à la pluie ou à l'humidité.
About RF Interference
Please note that wireless frequencies are shared with other radio services. According to ederal Communications Commission regulations,
“Wireless microphone operations are unprotected from interference from other licensed operations in the band. If any interference is received
by any Government or non-Government operation, the wireless microphone must cease operation...”
If you need help with operation or frequency selection, please contact your local dealer or Audio-Technica. Extensive wireless information
also is available at www.audio-technica.com.

best results, allow the antenna to hang freely and full length from the bottom of the transmitter.
If the received signal is marginal, experiment with different transmitter positions or try reposi-
tioning the receiver. Since the transmitter antenna simply screws in, check to make certain it is
snugly attached (finger-tight). Do not change the length of the transmitting antenna.
Green light indicates power is on and un-muted; red light indicates that audio is muted.
The light will blink when the batteries are low.
Liquid Crystal Display presents setup and operating information. The LCD in the transmitters is
