System Operation
Switch on the receiver. Do not switch on the transmitter yet. Selecting/Setting Frequency Selection of the desired operating frequency is made through the function menus. It�s usually best to start by setting the receiver�s frequency, to determine there is no local interference on that frequency. Then, always make certain to set the transmitter to the receiver�s exact frequency. The receiver�s unique Digital Tone Lock system squelches the audio only, permitting any RF energy on the frequency to show on the �RF� bar-meter. For multi-channel wireless systems, refer to page 12 for suggested frequency combinations. Visit the Audio-Technica Web site (www.audio-technica.com) for extensive wireless information and operating tips. Receiver On� The Alert indicator and the LCD window will light up; the normal-operation LCD display will appear after 1-2 seconds (Fig. D-1). If any of the bars show in the �RF� bar-graph meter, there may be RF interference in the area. If this occurs, select another frequency as explained below. (If the Meter Hold function has been selected, one of the RF bars will be flashing, indicating the lowest RF level received.) Setting Receiver Frequency 1. Press the Mode/Set button once; then only the frequency will appear in the LCD window. (The receiver is now in the Menu mode.) See Figure D-2. Press the Mode/Set button again; the Alert light will come on and the frequency in the window will flash. (The receiver is now in the Edit mode, Fig. D-3.) 3. Use the Up/Down arrow buttons to change the frequency. Press either arrow for single steps, or hold down either arrow for rapid cycling through the band. Frequencies �wrap around� to the other end of the range when the top or bottom of the band is reached. Choose a frequency appropriate for your area, avoiding frequencies with active TV channels. (See the frequency listings on page 12.) To activate this frequency selection, press and hold the Mode/Set button until the word �STORED� appears in the receiver�s window. (If you do not wish to complete this particular selection, just press the Mode/Set button once. The word �ESCAPE� will appear briefly in the window and the receiver will return to the Menu mode.) When finished entering a frequency, press the Down arrow button once to move to �QUIT�. Then press the Mode/Set button once to exit the menu. The �RF� and �AF� scales will reappear in the window, indicating the return to normal operation. 2. Use the Up/Down arrow buttons to change the transmitter frequency. Press either arrow for single steps, or hold down either arrow for rapid cycling through the range. Frequencies �wrap around� when the top or bottom of the band is reached. Select the exact frequency displayed on the receiver. To activate this frequency selection, press and hold the Set button until the word �STORED� appears in the transmitter�s window. (If you do not wish to complete this selection, just press the Set button once: the word �ESCAPE� will appear briefly in the window and the transmitter will return to the Menu mode.) When finished entering a frequency, press the Up arrow button once to move to �QUIT�. Then press the Set button once to exit the menu. The word �MENU� in the transmitter window will go off, indicating the return to normal operation.

When the transmitter is switched on and in normal operation, the receiver�s �RF� signal-level bars will display from bottom to top, with more bars indicating increased signal reception. For optimum performance at least four, and preferably five or more, of the RF indicators should be displayed. Setting Levels Correct adjustment of transmitter audio input, receiver audio output, and mixer/amplifier input and output levels is important for optimum system performance. Set Transmitter Audio Input Level A 4-position audio input gain setting, selected through the function menu, serves to match the audio input level to the transmitter for best modulation with minimum distortion. Available choices are +12 dB, +6 dB, 0 dB and � 6 dB. The default setting is +6 dB. Select the highest setting that does not result in over-modulation with the highest audio/instrument input levels (an AF indication on the receiver no higher than �0�); watch the receiver�s �AF� bar-graph �+3/+6� indications and the Alert light, to make certain that they are not triggered by the highest audio levels. The transmitter�s normally-on red LED power indicator will blink off if the peak audio input exceeds the maximum desirable level. RF Power Adjustment RF power may be set to �RF HI� (30 mW nominal) or �RF LOW� (10 mW nominal) through the function menu. The default setting is �RF LOW�. While the Hi setting normally provides maximum operating range, the Low setting will help extend battery life. The Low setting may also be preferred in multichannel systems, or when operating very close to the receiver, to reduce the possibility of interference or overload. RF Interference Please note that wireless frequencies are shared with other radio services. According to Federal 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 assistance with operation or frequency selection, please contact your dealer or the Audio-Technica professional division. Extensive wireless information also is available on the Audio-Technica Web site at www.audio-technica.com.

Transmitter On� Turn on the transmitter by pressing and holding the Power/Mute button (Fig. E/F) for a second or two, until the red power indicator and the LCD window have come on. Setting Transmitter Frequency 1. Press the Set button once and the small word �MENU� will appear above the frequency. Press the Set button again and the small flashing word �EDIT� will appear to the right of �MENU�. See Figures J-3 and J-4.
