This device complies with part 15 of the FCC 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 sub- ject 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 compli- ance 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.
Introduction
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.
Each 200 Series professional VHF wireless system includes a receiver and either a body-pack transmitter or a handheld microphone/transmitter on a specific crystal-controlled frequency. ATW-251 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-251 system.
Because 200 Series packaging is designed to hold all versions of the system, some compartments in the carton are intentionally left empty.
The ATW-R250 receiver includes a space-saving switching power supply that automatically adapts to changes in mains voltage. Unlike bulky linear power supplies, this switching power supply is lightweight and compact; it uses only a single outlet space.
The versatile ATW-T201 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-T202 handheld transmitter features a unidirectional dynamic microphone element.
Both the body-pack and handheld transmitters use internal
9-volt batteries and have Off/Standby/On switches, input Trim (level) adjustments and battery-save switches.
