Scan; Smarttune™ - Lectronics R400A Quick Start Manual

Scan

Navigate to the SCAN option from the menu, then press the rotary control to
activate the scan function. The receiver begins scanning the receiver's fre-
quency block. The receiver will continue to scan the tuning range continuously,
accumulating the highest peaks with each subsequent scan. Press the rotary
control to stop the scanning. Data gathered during the scanning process is
retained until Scan mode is exited.
With scanning stopped, the display will show the RF signals detected across
the entire tuning range. This "coarse view" presents a cursor (vertical line) that
can be moved with the rotary control.
A double press of the rotary control will switch the LCD to a "fine view" to
zoom in on the screen. In this mode, the cursor will remain in the center of the
display and turning the rotary control will move the background. Finer detail is
presented in this mode.

Scroll through the screen and find a frequency where no RF signals are
present (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. You will
be given the option of YES to switch to the new frequency just found, NO to
return to the frequency set before the scan, or SCAN to return to scanning.
Once the frequency has been selected, set the transmitter to match.
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.
Be sure to set the transmitter to match the new frequency.
