Controls and Functions
LCD Screen
The display is a highly visible backlit LCD with
screens for making all setup and level adjustments.
The transmitter can be powered up with or without
the RF output turned on. With the RF output turned
off, all adjustments can be made without creating
interference for other wireless systems in the vicinity.
For normal powering up and down, a countdown ap-
pears in the LCD. The buttons must be held in for the
duration of the countdown, which helps to prevent
accidentally turning the transmitter on or off.
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. An alkaline battery will have about 20
minutes of life left. When the LED begins to blink red,
there are only a few minutes of life.
Note: A NiMH rechargeable battery will give
little or no warning when it is depleted. If you
wish to use NiMH batteries, we recommend
trying fully charged batteries in the unit and
using the battery timer feature available in most
receivers to determine the available operating
time.
A weak battery will sometimes cause the PWR LED
to glow green immediately after the unit is turned on,
but will soon discharge to the point where the LED
will turn red or the unit will turn off completely. When
the transmitter is in SLEEP mode, the LED blinks
green every few seconds.
Audio Input Jack
This is a threaded locking connector that accepts the
Lectrosonics watertight WP connector.
Battery Compartment and Thumb Screw
The large knurled thumbscrews are retain the bat-
teries and maintain solid battery contact. The lan-
yard keeps the battery caps attached, but it can be
removed if desired using a 1/16 inch hex key (Allen
wrench).
Modulation LEDs
Proper input gain adjustment is critical to ensure
the best audio quality. Two red/green LEDs will glow
to accurately indicate modulation levels. The input
circuitry includes a wide range DSP-controlled limiter
to prevent distortion during high peak levels.
It is important to set the gain (audio level) high
enough to achieve full modulation during louder
peaks in the audio. The DSP-controlled limiter can
handle peaks over 30 dB above full modulation, so
with an optimum setting, the LEDs will flash red dur-
ing use. If the LEDs never flash red, the gain is too
low. The
-20 LED
turns red at 0 dB (full modulation).
Signal Level -20 LED -10 LED
Less than -20 dB Off Off
-20 dB to -10 dB Green Off
-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 gain and
low frequency roll-off settings. The UP and DOWN
arrows adjust the values. This button is also used with
the FREQ button to enter standby mode and to power
the transmitter on or off.
FREQ Button
The FREQ Button displays the selected operat-
ing frequency and also 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 Set-
ting. This button is also used with the AUDIO button
to enter standby mode and to power the transmitter on
or off.
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. Pressing both arrows simulta-
neously enters the lock countdown. When an attempt
is made to change a setting while the control panel is
locked, a message will flash on the LCD as a re-
minder that the unit is locked. Once locked, the but-
tons can only be unlocked by removing the battery,
or with the RM remote control.
Antenna
The fixed whip antenna is constructed with a flexible,
woven, galvanized steel mesh cable.
