TUNING
The Tuning setup screen allows
selection of one of four factory
set frequency groups (Groups A
through D), two user programmable
frequency groups (Groups U and V)
or the choice to not use groups at all.
In the four factory set frequency groups, eight frequen-
cies per group are preselected. These frequencies are
chosen to be free of intermodulation products. (See
Frequency Coordination.)
In the two user programmable frequency groups, up to
16 frequencies can be programmed per group.
Note: The Tuning Setup Screen only selects the
tuning mode (NORMAL or Group Tuning) and
not the operating frequency. Actual operating
frequencies are chosen through the Frequency
Window.
If NORMAL tuning mode is selected, the SEL Up and
Down buttons select the operating frequency in single
channel (100 kHz) increments and the MENU+Up and
MENU+Down shortcuts tune in 16 channel (1.6 MHz)
increments.
There are two group tuning modes: factory preset
groups (Grp A through D) and user programmable fre-
quency groups (Grp U and V).
In these modes, the SEL Up and Down buttons navi-
gate among the selected intermod-free frequencies in
the group (and the MENU+Up and MENU+Down short-
cuts jump to the first and last frequencies in the group.)
Also, a lower case a, b, c, d, u or v will be displayed to
the immediate left of the transmitter switch settings in
the Frequency Window. The letter identifies the selected
factory or user tuning group.
Any time the currently tuned frequency is not in the cur-
rent tuning group, the group tuning mode indicator will
blink. Any time the currently tuned frequency is in the
current tuning group, the group tuning mode indicator
will give a steady (non-blinking) indication.
If a factory tuning group has been selected, pressing
either the SEL Up or Down button will select the nearest
factory selected frequency in that group above or below
the current frequency.
User Programmable Frequency Group Behavior
The user programmable frequency groups “U” or “V”
work very similarly to the factory groups with a few
exceptions. The most obvious difference is the ability to
add or remove frequencies from the group. Less obvi-
ous is the behavior of a user programmable frequency
group with only one, or no entries.
A user programmable frequency group with only one
entry continues to display the single frequency stored
in the group no matter how many times the SEL Up or
Down buttons are pressed (provided the MENU button
is not pressed at the same time). The “U” or “V” will not
blink.
A user programmable frequency group with no entries
reverts to non-group-mode behavior, i.e., access is
allowed to all 256 available frequencies in the selected
receiver module’s frequency block. When there are no
entries, the “U” or “V” will blink automatically. However,
once a frequency has been added to the tuning group,
this behavior changes to group-mode behavior where
the MENU button must be pressed and held while either
the SEL Up or Down buttons are pressed to access
frequencies that are not part of the current tuning group.
Adding/Deleting User Programmable
Frequency Group Entries
Note: Each User Programmable Frequency Group
(“u” or “v”) has separate contents. We recommend
that you review the section titled Frequency
Coordination prior to adding frequencies in order
to minimize potential intermodulation problems.
1. Start from the Frequency Window and verify that a
lower case “u” or “v” is present next to the transmit-
ter switch settings.
2. While pressing and holding the MENU button press
either the SEL Up or Down button to move to one of
the 256 available frequencies in the block. Whenev-
er the selection comes to rest on a frequency that is
in the current group, the group tuning mode indica-
tor (letter “u” or “v”) will give a steady indication. On
frequencies that are not in the group, the indicator
will blink.
3. To add or remove the displayed frequency from the
group, hold down the MENU button while pressing
and holding the SEL Up button. The group tuning
mode indicator will stop blinking to show that the
frequency has been added to the group, or begin
blinking to indicate that the frequency has been
removed from the group.
COMPAT
The COMPAT setup screen selects
the type of transmitter used with the
UCR401. The available modes are:
400 - Lectrosonics 400 Series.
This is the default setting and should be used if your
transmitter supports it. This mode offers the best audio
quality.
100 - Lectrosonics 100 Series compatibility mode.
200 - Lectrosonics 200 Series compatibility mode.
IFB - Lectrosonics IFB compatibility mode.
MODE 3 and MODE 6 - Compatible with certain non-
Lectrosonics transmitters.
