First, turn off all of the transmitters you intend to use with the receiver.
Navigate to the SETUP/SCAN screen and press the MENU/SEL button to
start the scanner. The display will switch to the Scan Window (see illustration
above) and start scanning immediately. Allow the receiver to scan across the
entire tuning range at least once, then press the MENU/SEL button to stop
the scanning.
Scroll through the screen with the UP and DOWN buttons and find a frequen-
cy where no (or very weak) RF signals are present. Press the PWR/BACK
button to set the receiver to this new frequency.
Press both the UP and DOWN buttons at the same time to switch to the
Zoom View Window (see illustration above). In this view, the cursor remains
fixed in the center of the screen and the background scrolls behind it. The
frequency can be stepped up and down in 100 kHz increments using the UP
and DOWN arrow buttons.
When the receiver is configured for SWITCHED diversity (dual channel
mode), two cursors will appear when the scanning is stopped. Press MENU/
SEL to toggle between the two receivers. The cursor for the selected receiver
will be a dashed rather than solid line. Select each receiver and use the UP
and DOWN buttons to locate a frequency with no (or very weak) RF activity.
Keep the frequencies of the two receivers at least 700 kHz apart to minimize
de-sensing (short range) issues. This spacing is a "worst case" approximation
assuming the transmitters are about 25 feet from the receiver antennas.
Data gathered during a scan is stored until it is intentionally erased or the
power is turned off. Previous data will remain and subsequent scans can be
made to search for additional signals or to accumulate higher peaks.
To clear the scan memory and screens, press the back button several times to
return to the Main Window, then press and hold the PWR/BACK button briefly.
As soon as Powering off... appears on the display, release the button. The
receiver will remain turned on, and the scan data will be erased.
Set your transmitter to the same frequency as shown on the receiver display,
turn the transmitter on and verify that a strong RF signal is present.
