Controls and Functions

LCD Screen

The display is a highly visible backlit LCD with screens

for making all setup and level adjustments. The trans-

mitter can be powered up with or without the RF output

turned on. With the RF output turned off, all adjust-

ments 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 ac-

cidentally 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. 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 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 batteries

and maintain solid battery contact. The lanyard 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 ac-

curately 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 during 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 operating fre-

quency and also toggles the LCD between displaying

the actual operating frequency in MHz and a two-digit

hexadecimal number that corresponds to the equiva-

lent Lectrosonics Frequency Switch Setting. This but-

ton 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 simultaneously

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 reminder that

the unit is locked. Once locked, the buttons 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.
