UHF Wireless Diversity Receiver

Rio Rancho, NM – USA

From the Main Window, users can navigate to the
Frequency, Battery Level and Setup windows. They can
also access Frequency Scan Mode, Lock or Unlock the
reciever and turn on/off the Pilot Tone. These functions
are accessed via the MENU and SELECT buttons.

FREQUENCY WINDOW

The Frequency Window displays the
current TV channel, the transmitter
switch settings and the receiver’s
operating frequency.

TVxx - the television broadcast channel the receiver is
currently turned.

Transmitter switch settings - the correct settings for the
frequency switches on the corresponding transmitter.
(Refer to the transmitter instruction manual.)

Frequency - the current frequency the receiver is tuned.
Pressing the SELECT Up or Down buttons will change
the receiver’s frequency. As it changes, the displayed
transmitter switch settings will also change. Ensure the
transmitter’s frequency is changed to match the
receiver’s operating frequency.

For units with firmware version 4.1 or later, holding the
MENU button down while pressing either the SELECT
UP or DOWN arrow, moves the frequency 16 channels
at a time.

BATTERY LEVEL WINDOW

Displays the transmitter (TX) and receiver (RX) battery
voltage in tenth volt increments. The icons flash when
the voltages drops below suggested optimum working
levels. Typically, there will be about
one hour operating time remaining
after the indicators begin to flash. RX
changes to EX when operating on
external power and displays the
external power source voltage. (Disclaimer: We don’t
guarantee 0.1 Volt accuracy.)

SETUP WINDOW

In the SETUP window, the SELECT
Up and Down buttons scroll through a
list of four possible destinations:
EXIT, LEVEL, TONE and TXBAT.

Each destination allows the user to customize the
receiver’s operating parameters.

LEVEL

The LEVEL setup screen displays the
audio output level of the receiver in
dBu. Use SELECT Up or Down to
change this level. (Range is from -50
to +9 dBu in 1dB steps.) Press MENU
to exit this screen.

TONE

The TONE setup screen enables an
audio test tone at the receiver output
for precise level matching with other
equipment. The first screen prompts
you to press SELECT Up to enable
the tone at the receiver output. Press
SELECT Up again to access the LVL
screen that allows the tone level to be
adjusted in 1 dB steps using the SELECT Up and Down
buttons. When the audio test tone is enabled, the
received audio is muted and an internally generated 1
kHz test tone is routed to the XLR connector. Since
there is only one audio output level setting for both
received audio and tone, the level set here will
supersede the setting made via the LEVEL setup screen.
(It may be necessary to reset the receiver’s audio output
level through the LEVEL setup screen.) The test tone
has 5% distortion and is intended for confirmation of
output levels only. Press MENU to stop the tone and
leave this screen.

TXBAT

The TXBAT setup screen allows users
to select the exact battery being used
in the transmitter for accurate battery
level monitoring. Four different types of
batteries are commonly used in
Lectrosonics transmitters: 9 volt alkaline, 9 volt lithium,
AA alkaline, and AA lithium. Correctly set, this will
ensure that the information in the MAIN and BATTERY
LEVEL windows will be accurate and adequate warning
will be provided in advance of battery failure. Press
MENU to exit this screen.
