Smarttune; Scan - Lectronics R400A Quick Start Manual

SmartTune

™
SmartTune™ automates the discovery of a clear operating frequency. It does
this by scanning all the available operating frequencies within the system's fre-
quency block range (in 100 kHz increments) and then selecting the frequency
with the least amount of RF interference. When SmartTune is complete, it
returns to the Main Window displaying the operating frequency and transmit-
ter switch settings for the clear channel discovered during scanning.

Scan

Navigate to the SCAN option from the menu, then press the MENU control
to activate the scan function. The receiver begins scanning the receiver's
frequency block. The receiver will continue to scan, accumulating the highest
peaks with each subsequent scan, until stopped by the user. Data gathered
during the scanning process is retained until 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. Rotate the MENU control
to scroll the cursor across the tuning range. As the cursor scrolls across the
frequency band, Frequency Select Switch settings for the associated transmit-
ter are shown in the upper right corner of the screen.
Double pressing the MENU control switches the display to Fine View which
displays an expanded portion of the spectrum around a fixed, vertical cursor.
As with the Coarse View, cursor movement across the frequency band results
in the displaying of the associated transmitter Frequency Select Switch set-
tings in the upper right corner of the screen.
Scroll through the screen and find a frequency where no RF signals are pres-
ent (or in the worst case, only very weak RF signals). With the cursor on this
frequency, press the PREV MENU button to exit from scan mode.
When exiting the scan mode, you are given the option to select either the fre-
quency the unit was on before entering the scan mode, or the frequency just
selected in the scan mode. Select NO to return to the frequency that was set
before entering the scan mode. Select SCAN to resume scanning.
Note: Ensure
the transmitter's
Frequency Select
Switch settings
are the same
settings as shown
on the display
and your system
will be ready for
operation.
