Rf On?
The transmitter output can be switched
on or off with this menu item. This is
useful, for example, when the transmitter
is in the "standby" mode during setup,
allowing it to be turned on for normal
operation without having to cycle the
power.

This menu item can also be used to
change the transmitter to the "standby"
mode with the RF output turned off for
additional setup.
Default
The default setting simple returns the
transmitter back to the factory settings
and any of the menu items can be read-
justed from that default point.
Input Gain Adjustment
The two bicolor Modulation LEDs (lo-
cated at the bottom of the control panel)
provide a visual indication of the audio
signal level entering the transmitter.
The modulation
LEDs are oriented
and labeled to be
read when holding
the mic capsule in
front of your mouth.
The gain should
be set so that the
-20 LED just turns
red on the loudest
peak.
The LEDs will glow either red or green to
indicate modulation levels as shown in
the following table.

It is best to go through the following
procedure with the transmitter in the
"standby" mode so that no audio will
enter the sound system, which could
cause feedback.
1) With fresh batteries in the trans-
mitter, power the unit on into
"standby" (no transmission) mode.
2) Press the MENU/SEL button once
to enter the setup menu. Use the
UP/DOWN buttons to select Gain.
Press the MENU/SEL button again
to enter the setup screen.
3) Hold the microphone the way it will
be used in actual operation.
4) Speak or sing at the same voice
level that will actually be used dur-
ing the program, while observing
the modulation LEDs. Use the UP/
DOWN buttons to adjust the gain
until the –20 dB LED starts to
flicker red and the –10 dB glows
green.
5) Once the audio gain has been set,
the signal can be sent through
the sound system for overall level
adjustments, monitor settings, etc.
To do this, the unit must be set to
transmit (see Powering On and
Off, and the Standby Mode on
page 3).
NOTE: Full modulation is
achieved when the -20 LED first
turns red. 30 dB of clean limiting
is available above this point.
