Thank you for purchasing this Audio-Technica product. This PLL synthesized wireless microphone system operates in the UHF band frequency, with two groups of four frequencies. Please read this manual carefully before operating the AT-One system. This manual covers the function and operation of the wireless microphone system.

Safety

-To prevent fire or shock hazard, do not expose this appliance to rain or moisture

-To prevent fire, do not cover the ventilation of the apparatus with newspaper, tablecloths, etc.

-Do not expose this apparatus to drips or splashes

-Do not place any objects filled with liquids, such as vases, on the apparatus

-Do not install this apparatus in a confined space such as a bookcase or similar unit

-The aparatus should be located close enough to the AC outlet so that you can easily grasp the AC adapter at any time. In case of emergency, disconnect the AC adapter quickly.

-Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type.

-If the transmitter is not in use for an extended period, remove the batteries to avoid damage

-Do not dispose of used batteries with domestic rubbish. Be sure to dispose of batteries in accordance with your local waste disposal rules.

-When disposing of the equipment, remove the batteries, separate the case, circuit boards and cables, and dispose of all components in accordance with local waste disposal rules.

The circuits inside the receiver and transmitter have been precisely adjusted for optimum performance and compliance with government regulations. Do not attempt to open the receiver or transmitter. To do so will void the warranty, and may cause improper operation.

Receiver Functions

Receiver Front:

1.Antenna: Detachable UHF antenna with BNC connector

2.Power Button

3.RF Red LED: Displays the reception status of the RF signal

4.AF Green LED: Displays the reception status of the AF signal

5.UP Channel Button: Tap forward to select an interference free channel

5. SQ (Squelch):	Turn the squelch to the lowest possible setting (counter
	clockwise) to eliminate any interfering signals. In RF
	crowded environments (other wireless microphones, LTE,
	etc.) it can be required to increase the squelch level
	(clock wise) to block out unwanted noise. Please note
	that this will reduce the operating distance of the system,
	so always seek the lowest possible setting.
