be to the left (ground connected). If hum caused by a ground loop occurs, slide switch to the right (ground lifted).

12.BALANCED AUDIO OUTPUT JACK: XLRM-type connector. A standard 2-conductor shielded cable can be used to connect the receiver output to a balanced microphone-level input on a mixer or integrated amplifier.

13.UNBALANCED AUDIO OUTPUT JACK: 1/4" phone jack. Can be connected to an unbalanced aux-level input of a mixer, guitar amp or tape recorder.

14.POWER INPUT JACK: Connect the DC plug from the included in-line AC adapter.

15.CORD HOOK: Loop the small DC cord around the cord hook to keep the DC plug from pulling out accidentally.

Power On/Off

To turn the receiver on, press in the Power switch. The Alert light and the LCD window will come on (about 1-2 seconds). The operating frequency will be displayed in the window after the power-up sequence. To turn the receiver off, press the Power switch again.

LCD Window

The LCD (Liquid Crystal Display) presents a great deal of setup and operating information clearly and conveniently. (See Figure D for examples.)

Up/Down Arrow Buttons

In conjunction with the Mode/Set button, the arrow buttons permit moving through the menu of functions, and they offer a choice of settings within each function.

Mode/Set Button

The Mode/Set button shifts the receiver from normal operation into Menu mode and, in conjunction with the Up/Down arrow buttons, permits selection of different features and changing of their stored values in the Edit mode.

How to Make Setting Changes

1.From the normal operating mode, press the Mode/Set button once to enter the Function Menu mode. (Only the frequency will remain in the LCD window, and the receiver’s audio output will be cut off.)

2.Use the Up/Down arrow buttons to reach the desired function.

The value in the LCD window is the current setting for that function.

3.Press the Mode/Set button once again to open the list of available choices for that function. The value will flash, indicating that it can be changed (Edit mode).

4.Use the arrow buttons to go through the available choices, stopping on the desired new choice.

5.(a) To accept and enter the new choice, press and hold the Mode/ Set button until “STORED” appears in the LCD. This changes the value and puts the function of the buttons back at Menu level (step 2 above). (The “B” tuner light will come on while the Mode/Set button is depressed, to confirm its action.)

(b) To “back out” of the Edit mode without making a new choice, simply press the Mode/Set button once. The word “ESCAPE” will appear in the window and the function of the buttons will revert to the Menu level (step 2 above), without making any changes.

6.Repeat this selection process for any other function changes

desired. When finished with any changes, use the arrow buttons to

move to “QUIT”. Press the Mode/Set button once to exit the menu and return the receiver to normal operation. (“RF” and “AF” will reappear in the window, indicating the return to normal receiver operation, with the receiver’s audio output again enabled.)

Frequency Group Selection

To select a frequency scan group, press the Mode/Set button, then use the arrow button until the desired group appears in the display. To store the selected frequency scan group, press the Mode/Set button to enter the desired group; then use the arrow button to start the scan. When a flashing number is displayed, press and hold Mode/Set button to select the frequency. See detailed instructions in System Operation.

How to Restore Default Settings

To return all the receiver functions to their original factory default settings, first turn the receiver off. Then hold in the Mode/Set button while pressing and releasing the Power switch. The LCD will briefly show “RESET”, followed by “WAIT” (release the Mode/Set button), before commencing normal-mode operation at the default settings.

When the receiver is in the Menu or Edit mode, its audio output is silenced. Once control-setting operations are completed (or Escape is used), normal receiver operation will resume with its audio output restored.

While in the Edit mode, if no action is taken for approximately 30 seconds (no buttons pressed), the receiver will “back out” to the Menu mode. Similarly, after about 30 seconds of inaction in the Menu mode, the receiver will “back out” to normal receiver operation with audio output restored.

High-pass Filter

Internal high-pass filter circuitry may be set to four positions: High- pass Off, or a 6 dB, 12 dB or 18 dB slope at 150 Hz. The default setting is Off (“HP OFF”). Increasing the slope of the high-pass filter further suppresses unwanted low frequencies, while maintaining the frequency response in the desired audio range.

Meter Hold Setting

When activated (“MH ON”), this function permits the bar-meters in the LCD window to capture and display the highest-level “AF” audio modulation (a solid bar) and the lowest-level “RF” signal (a flashing bar) received from the transmitter. This is particularly useful when setting up the system initially, during a sound-check, or when diagnosing operating problems. The default setting is Off (“MH OFF”).

When the Meter Hold is On, it is possible to reset it – to obtain a new set of RF and AF readings – without turning it off-and-on using the Menu/Edit functions. Simply press the transmitter’s Power/Mute button once (to mute the transmitter) and wait until the receiver’s Alert light comes on, indicating the Mute condition. Then press the transmitter’s Power/Mute button once again, to un-mute the transmitter. After the Alert light goes out, a new set of min/max RF/AF readings will be indicated on the bar-meters. (Note that, depending upon the digital updating-and-confirming sequence of the Mute condition data from the transmitter, it may take several seconds for the Alert light condition to change. The Meter Hold function is not reset until the Alert light has turned on, then turned off.)

Digital Tone Lock™ Squelch

The 3000 Series employs a unique Digital Tone Lock squelch system that provides enhanced rejection of interference. In addition to providing highly effective control of unwanted noise, the Tone Lock signal from the transmitter also conveys data on the transmitter’s battery condition and mute status back to the receiver for display.
