MENU button.
TxBatt
The TxBatt setup screen allows the selection of the exact
battery type being used in the transmitter to provide
more 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. Rechargeable NiMH batteries can also
be used in the transmitters (see TIMER below). Cor­
rectly set, this feature will ensure that adequate warning
will be provided in advance of battery failure.
In 400 Series and 200 Series compatibility modes, the
TxBatt menu offers five choices:
9V ALK - Transmitter using a 9V alkaline battery.
Monitors voltage with battery icon in main window.
The relative remaining battery voltage is displayed in
the TxBatt setup screen.
9V LTH - Transmitter using a 9V lithium battery.
Monitors voltage with battery icon in main window.
The relative remaining battery voltage is displayed in
the TxBatt setup screen.
AA ALK - Transmitter using a AA alkaline battery.
Monitors voltage with battery icon in main window.
The relative remaining battery voltage is displayed in
the TxBatt setup screen.
AA LTH - Transmitter using a AA lithium battery.
Monitors voltage with battery icon in main window.
The relative remaining battery voltage is displayed in
the TxBatt setup screen.
TIMER - Transmitter using any battery, displays time
elapsed in the lower left corner of the TxBatt setup
screen The TIMER's colon blinks when the timer is
running. When the transmitter or R400 receiver is
powered OFF, the timer will retain the last time
setting and resume when a signal is detected from
the transmitter. To reset the timer, navigate to the
TIMER setup screen and quickly press and release
the PREV MENU button and the MENU control at
the same moment. The TIMER mode is most useful
for NiMH batteries as they do not exhibit reliably
identifiable voltage drops as they discharge.
For other compatibility modes, no battery telemetry
information is available so the TxBatt setup screen offers
TIMER as the only choice. Exit this setup screen by
pressing the PREV MENU button.
SmartNR
Available in 400 Series Compatibility Mode only, the
Smart NR setup screen is used to select one of three
noise reduction modes:
OFF - No noise reduction is performed and complete
transparency is preserved. All signals
presented to the transmitter’s analog front
end, including any faint microphone hiss, will
be faithfully reproduced at the receiver.
NORMAL (factory default) - Enough noise reduction
is applied to remove most of the hiss from
the mic preamp and some of the hiss from
lavaliere microphones. The noise reduction
benefit is dramatic in this position, yet the
degree of transparency maintained is
exceptional.
FULL - Enough noise reduction is applied to remove
most of the hiss from nearly any signal
source of reasonable quality, assuming
levels are set properly at the transmitter.
Rotate the MENU control to select the noise reduction
mode. Exit this setup screen by pressing the PREV
MENU button.
BACK
Rotate the MENU control to select BACK, then push the
MENU control to return to the TopMenu window.
LockSet
LockSet is used to lock the R400 settings. When locked,
the use of the MENU functions is limited to “view only”
and attempts to change selections will result in a screen
displaying the word “LOCKED! (To Unlock, Use LockSet
Menu)” Also, the unit cannot be used for RF scanning
when it is set in the LOCKED state.
To LOCK the R400 - Press the MENU control to enter
the TopMenu, then rotate the MENU control to select
LockSet. Press the MENU control to open the Lockset
window, rotate the MENU control to select LOCK, then
push either the MENU control or the PREV MENU
button to exit to TopMenu.
To UNLOCK - Repeat the steps above and select NOT
LOCKED.
SmrtTun (Firmware version 1.5 and later)
SmrtTun automates the discovery of a clear operating
frequency. It does this by scanning all the available
operating frequencies within the systems frequency
block range (in 100 KHz increments) and then selecting
the frequency with the least amount of RF interference.
When SmrtTun is complete, it returns to the Main
Window displaying the operating frequency and trans­
mitter switch settings for the clear channel discovered
during scanning.
Scan
To use the integrated scanning function, press the
MENU control, rotate it to highlight Scan, and then press
the MENU control. The display switches to the Scan
Window and automatically starts progressively scanning
the selected frequency block. The receiver will continue
to scan, adding data with each subsequent scans, until
stopped by the user. Data gathered during the scanning
process is retained Scan mode is exited.
To stop scanning (but not exit Scan mode), press the
MENU control once. The display switches to the Coarse
View window. In this mode, each vertical band of the
display represents four frequencies (400 kHz). Rotate
