Controls and Functions
LCD Screen
The LCD is a numeric-type Liquid Crystal Display with
several screens that allow settings to be made with the
AUDIO and FREQ buttons, and the UP and DOWN ar-
row buttons to congure the transmitter. The transmitter
can be turned on in a “standby” mode with the carrier
turned o to make adjustments without the risk of inter-
fering with other wireless systems nearby.
Power LED
The PWR LED glows green when the batteries are good.
The color changes to red when there is about 20 min-
utes of life left. When the LED begins to blink red, there
are only a few minutes of life.
A weak battery will sometimes cause the PWR LED to
glow green immediately after being put into the unit, but
will soon discharge to the point where the LED will go
red or shut o completely.
Audio Input Jack
The XLR input jack on the transmitter accommodates
hand-held, shotgun and measurement microphones.
Phantom power can be set at various levels for use with
a wide variety of electret microphones.
Battery Compartment
The battery compartment door is made of machined
aluminum and is hinged to the housing to prevent it be-
ing damaged or lost.
USB Port
USB Port for rmware updates in the eld.
IR Port
IR (infrared) port for fast setup.
Modulation LEDs
The Modulation LEDs provide a visual indication of the
input audio signal level from the microphone. These two
bicolor LEDs can glow either red or green to indicate
modulation levels. Full modulation (0 dB) occurs when
the -20 LED rst turns red.
Signal Level -20 LED -10 LED
Less than -20 dB
O O
-20 dB to -10 dB Green O
-10 dB to +0 dB
Green Green
+0 dB to +10 dB Red Green
Greater than +10 dB
Red Red
Audio Button
The AUDIO button is used to display the audio level set-
ting, low frequency roll-o and phantom power mode.
Repeatedly pressing the button will cycle through the
available settings, allowing the UP and DOWN arrow
buttons to adjust the values.
Freq Button
The FREQ Button displays the selected operating
frequency and also toggles the LCD between displaying
the actual operating frequency in MHz and a two-digit
hexadecimal number. Frequencies can be selected in
either 100kHz or 25kHz steps. The appearance of the
hexadecimal number is dierent in the 100kHz step size
mode than in the 25kHz step size mode.
NOTE: The FREQ and AUDIO buttons are used
together to enter the standby mode and to turn
the power on or off.
UP/DOWN Arrows and Panel Lockout
The UP and DOWN arrow buttons are used to select the
operating frequency, adjust the audio level, or set the
Compatibility Mode.
Pressing both arrows simultaneously enters the lock
countdown. Holding the two buttons in until the count-
down is completed locks the control panel buttons so
they can only be used to display current settings. “Loc”
is displayed to indicate the controls are locked when a
button is pressed while the panel is locked.
Once locked, the control panel is unlocked by removing
the battery or using the remote control “dweedle” tones.
Antenna
An antenna is formed between the housing and the
attached microphone, operating much like a dipole. At
UHF frequencies the length of the housing is similar
to 1/4 wavelength of the operating frequency, so the
antenna is surprisingly ecient, which helps extend the
operating range and suppress noise and interference.
