Features
LCD Screen
The LCD is a numeric-type Liquid Crystal Display with
several screens that allow settings to be made with the
MENU/SEL
and
BACK
buttons, and the
UP
and
DOWN
arrow buttons to configure the transmitter. The trans-
mitter can be turned on in a “standby” mode with the
carrier turned off to make adjustments without the risk
of interfering with other wireless systems nearby.
Power LED
The PWR LED glows green when the batteries are
charged. The color changes to red when there is about
20 minutes 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 off completely.
Key LED
The blue Key LED will blink if an encryption key is not
set and “no key” will blink on LCD. The Key LED will
remain on if the encryption is set correctly and will turn
off in Standby mode.
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 first turns red.
