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.
The squelch level is adjustable from 15 dB (the default value) to 39 dB in 6 dB steps.
Increasing the squelch level – also called “tightening the squelch” – can cause a
reduction in useable range of the wireless transmitter, so use the lowest value that
reliably mutes the unwanted RF signals. (If interference is a problem, first consider
trying a different frequency.)

Transmitter Controls And Functions
Refer to Figures E, F, G and H on page 2 + 3 for an overview of transmitter features and
controls.
LCD Window
The Liquid Crystal Display presents a great deal of setup and operating information
clearly and conveniently (See examples in Fig. J). The LCD in the transmitters is
designed for greatest contrast and best viewing with the window rotated somewhat
away from the viewer (about 30 degrees), not straight-on, for a more convenient
holding/viewing position.
Power/Mute Button
The transmitters have a combination Power and Mute switch. When used in
combination with the programmed choices explained below, the various functions
available to the transmitter user may be tailored to fit personal preferences or
particular situations of use.
Power On/Off
To turn the transmitter on, press and hold the Power/Mute button until the red power
indicator and the LCD window come on (about 1-2 seconds). The operating frequency
will show in the window after the power-up sequence.
To turn the transmitter off, press and hold the Power/Mute button again, until the red
power indicator and the LCD window are extinguished (about 1-2 seconds). The LCD
window will show “PWR.OFF” before shutdown.
Mute Off/On
When the transmitter is muted, it produces RF with no audio signal modulation. When
the transmitter is un-muted, it produces both RF and audio.
To mute the transmitter (cut off the audio, but continue the RF output), press and
release the Power/Mute button once . A small “MUTE” will appear in the LCD window,
just below the frequency (Fig. J-2).
To un-mute the transmitter (restore the audio), press and release the Power/Mute
button
once again. The “MUTE” will disappear from the LCD window.
