PWR.LOC Power is locked On as of the time “PWR.LOC”
is applied. The Mute functioning is unaffected.
Note: When in the
PWR.LOC mode, the
transmitter may be tur
ned off by: (1) Re-accessing
the .
LOC Menu and changing the setting, or
(2) Removing and re-installing the batteries.
When the transmitter is turned on again, it will
power-up in the
NO.LOC mode. (Only the
PWR. LOC function will change when batteries
are removed; all other settings remain stored in
memory.)
If an attempt is made to take an action that currently is locked
out, the LCD will display
“LOC.KED” briefly
, then return to its
pr
eviously-displayed contents.
Audio Input Selector
The UniPak™ body-pack transmitter provides input connections
for both low-impedance (Lo-Z) microphones and high-
impedance (Hi-Z) instruments. A wide range of Audio-Technica
Wireless Essentials™ microphones and cables is available
pre-terminated with the appropriate professional latching
connector. (See page 11.)
Selection of the desired input – microphone or instrument – is
made through the function menu. Depending upon the input
selected, a small
“MIC” or “INST” will show in the LCD
window, just below the frequency. (In the handheld transmitter,
only
“MIC” will show in the LCD window.)
Setting 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 value 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” meter “+3/+6” indications and
the Alert light to make certain 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.
Restore Default Settings
A “PRESET” selection in the menu permits resetting of all
transmitter functions to their factory-default values.

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.
Power/Mute Locks
Programmable Power/Mute Locks limit the functioning of the
Power/Mute button as desired for particular users and/or appli-
cations. Power can be locked On; Mute can be locked Off.
Selection of the desir
ed locks, if any
, is made thr
ough the
function menu:
Setting

NO.LOC The normal Power and Mute functions are fully
operational.
ALL.LOC Both the Power and Mute functions ar

“ALL.LOC” is
applied. (Power On, and Mute either On or Off.)
Note:
ALL.LOC must be re-accessed and the
setting changed to turn the transmitter off.
MUT

In this mode, the audio cannot be muted. The
Power functioning is unaf
