Controls and Functions
LCD Screen
The LCD is a numeric-type Liquid Crystal Display with
screens for adjusting power, frequency, audio level and
low frequency audio roll-o. The transmitter can be
powered up with or without the RF output turned on. A
countdown appears in the LCD when powering on and
o, allowing the transmitter to be turned on without RF
for adjustments, and to prevent accidentally turning it o
with momentary button presses.
Power LED
The PWR LED glows green when the battery is good.
The color changes to red when there is about 30 minutes
of operation left with the recommended lithium battery.
When the LED begins to blink red, there are only a few
minutes of life.
The exact point at which the LED turns red will vary with
battery brand and condition, temperature and current
drain. The LED is intended to simply catch your attention,
not to be an exact indicator of remaining time.

Green RedBlink
A weak battery will sometimes cause the PWR LED to
glow green immediately after the transmitter is turned on,
but will soon discharge to the point where the LED will
turn red or the unit will turn o completely.
Power LED O Feature
In normal operating mode, the DOWN and UP Arrow but-
tons may be used to turn the PWR LED indicators o and
on. This setting does not persist through a power cycle
nor does it aect the LCD backlight.
Audio Input Jack
The Servo Bias input circuitry accommodates virtually
every lavaliere, handheld or shotgun microphone avail-
able, plus line level signals.
Battery Compartment and Thumb Screw
The large knurled thumbscrew is used to release or se-
cure the Battery Compartment Cover Plate.
Modulation LEDs
Proper input gain adjustment is critical to ensure the best
audio quality. Two bicolor LEDs will glow either red or
green to accurately indicate modulation levels. The input
circuitry includes a wide range DSP controlled limiter to
prevent distortion at high input levels.
It is important to set the gain (audio level) high enough
to achieve full modulation during louder peaks in the
audio. The limiter can handle over 30 dB of level above
full modulation, so with an optimum setting, the LEDs will
ash red during use. If the LEDs never ash red, the gain
is too low. In the table below, +0 dB indicates full modu-
lation.

AUDIO Button
The AUDIO button is used to display the audio level and
low frequency roll-o settings. The UP and DOWN ar-
rows adjust the values.
The AUDIO button is also used with the FREQ button to
enter standby mode and to power the transmitter on or o.
FREQ Button
The FREQ Button displays the selected operating
frequency and toggles the LCD between displaying
the actual operating frequency in MHz and a two-digit
hexadecimal number that corresponds to the equivalent
Lectrosonics Frequency Switch Setting.
Up/Down Arrows
The Up and Down arrow buttons are used to select the
values on the various setup screens and to lock out the
control panel.
Antenna
The transmitter uses a whip antenna with a exible wo-
ven, galvanized steel mesh cable and a standard SMA
connector.
