Main Window
The appearance of the LCD Main Window will change
according to which diversity mode Selected. When set
to SWITCH, the screen will be split to show both receiv
-
ers at the same time.
With the DIV MODE set
to SWITCHED, two audio
channels will be displayed.
When set to RATIO, a single audio channel is displayed
since the receiver are combined to pick up the same
transmitter.
With the DIV MODE set to
RATIO, a single audio channel
will be displayed.
Frequency Screen
Press Sel from the Main Window once for Receiver 1
and twice for Receiver 2. The Selected receiver is de-
noted in the upper left corner of the screen.
Press BACK to move from
Receiver 2 back to Receiver 1

80
652.800
2
AF
657.500
In this example, the upper screen denotes that receiver
1 is set at 652.800 MHz, requiring that the correspond
-
ing transmitter hex switches be set at 80 for this fre
-
quency. Lectrosonics transmitters with LCD interfaces
allow frequency to be set in MHz or hex settings.
Press the Up and Down buttons to change the frequen-
cy of the receiver. When the TUNING mode is set to
NORMAL, the SEL Up and Down buttons tune in single
channel increments. In the group tuning modes, the Up
and Down buttons step through the pre-coordinated
frequencies.
NOTE: When operating in the 2-channel mode,
always set Receiver 2 to a higher frequency than
Receiver 1 by least 400 kHz (four standard steps).
In addition, receiver performance will be degraded
if Receiver 1 is between 4.2 and 4.8 MHz higher
than Receiver 2, at which time the LCD will
periodically flash this message:
FREQ.

Setup Screens
From the Main Window, press SEL three times to
enter the setup SEL. Press UP and/or DOWN to scroll
through the available SEL items. Press SEL to enter
the setup screen for the selected SEL item. For those
SEL items that allow separate settings for each re
-
ceiver, press SEL repeatedly to toggle back and forth
between Receiver 1 and Receiver 2, then press the UP
and DOWN buttons to select the value or option. Press
BACK to return to the setup SEL to select the next item.
LEVEL
This setup screen displays the audio output level of the
receiver in dBu. Use the SEL Up or Down buttons to
change the level. Range is from -50 to +5 dBu in 1 dB
steps. Press the SEL button to leave this screen.
The output levels at the two jacks may be set indepen
-
dently, regardless of the diversity mode setting.
SCAN
This function provides a fast and reliable method of
finding clear channels for each receiver. Press SEL to
start the scanning. Follow the procedure outlined in the
navigation map on the previous page and on the page
entitled Scanning for Clear Frequencies for instructions
on using the scanner to find clear channels.
DIVMODE
The SWITCH diversity mode allows the two internal
receivers to operate independently on different frequen-
cies and settings with two different transmitters. When
this mode is selected, the setup screens will prompt you
to select the receiver to be adjusted.
The RATIO mode combines the two internal receiv
-
ers to pick up the same transmitter and mix their audio
outputs for ratio diversity reception. In this mode, the
setup screens will prompt you for a single value which
will automatically be set for both receivers.
COMPAT
The COMPAT setup screen selects the type of transmit-
ter used with the receiver. The available modes are:
•
HYB is used with Lectrosonics Digital Hybrid trans-
mitters. This is the default setting and should be
used if your transmitter supports it. This mode offers
the best audio quality.
• 100
for Lectrosonics 100 Series transmitters.
• 200
for Lectrosonics 200 Series transmitters.
• IFB
for Lectrosonics IFB transmitters.
• M.3
and M.6 are compatible with certain non-
Lectrosonics transmitters. Contact the factory for
details.
TUNING
In addition to the NORMAL mode, this screen also
allows Selection of one of four factory pre-selected
frequency groups (Groups a through d) or two user
programmable frequency groups (Groups u and v).
•
NOR allows selection of all 256 frequencies that the
receiver will tune. Each press of the UP or DOWN
button will step in 100 kHz increments to the next
frequency.
•
a, b, c, d sets the receiver to tune only factory
preselected frequencies, up to eight in each group.
Each press of the UP or DOWN button will step to
the next frequency in the group.
