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 turned 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
previously-displayed contents.
Audio Input Selector
The UniPak™ body-pack transmitter provides input connections
for both low-impedance (Lo-Z) microphones and highimpedance (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 12.)
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.
1. Press the Set button once to move to Menu mode.
2. Press the Up arrow twice to move to
“PRESET”
in the
LCD window.
3. Press the Set button once and
“LOAD”
will appear in the
LCD.
4.
Press and hold
the Set button until
“DEF”
appears in the
LCD.
5.
Press and hold
the Set button until
“LOADED”
appears
briefly in the LCD. The window will then revert to
“PRESET”
.
6. Press the Down arrow once to move to
“QUIT”
.
7. Press the Set button once to exit the Menu mode and
return to normal operation, with all factory-default settings
restored.
Refer to Figures E, F, G and H on pages 18 and 19 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.
Power/Mute Locks
Programmable Power/Mute Locks limit the functioning of the
Power/Mute button as desired for particular users and/or applications. Power can be locked On; Mute can be locked Off.
Selection of the desired locks, if any, is made through the
function menu:
Setting
Description
NO.LOC
The normal Power and Mute functions are fully
operational.
ALL.LOC
Both the Power and Mute functions are locked
into their status as of the time
“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.LOC
In this mode, the audio cannot be muted. The
Power functioning is unaffected. (If
MUT.LOC
is
applied while the transmitter is muted, pressing
the Power/Mute button once will return to
un-muted operation; thereafter the Mute function
is disabled until the setting is changed again.)
