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.
When the receiver is configured for SWITCHED diver-
sity (dual channel mode), two cursors will appear when 
the scanning is stopped. The cursor for receiver 1 is a 
dashed line and the cursor for receiver 2 is a solid line. 
Press MENU/SEL to toggle between the two receivers 
(selected channel will blink). Select the channel and 
use the UP and DOWN buttons to move the cursor and 
locate a frequency with no (or very weak) RF activity.
Scroll through the screen with the UP and DOWN but-
tons and find a frequency where no RF signals (or in 
the worst case, only 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 illustra-
tion 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.
NOTE: The appearance of the cursors as described 
above started with firmware v1.15. In previous versions 
the selected cursor would appear as a dashed line, and 
neither cursor would blink.
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 assum-
ing the transmitters are about 25 feet from the receiver 
antennas.
IMPORTANT:
FREQ.
WARNING
Performance will be degraded if 
Receiver 2 is set 4.2 to 4.8 MHz higher 
than Receiver 1. The LCD will also flash 
this message periodically.
Data gathered during a scan is stored until it is inten-
tionally 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 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/s to match the corresponding 
receiver/s (CH1 or CH2) on the receiver display. Turn 
the transmitter on and verify that a strong RF signal is 
present. If your transmitter has an IR (infrared) port, you 
can transfer the frequency setting using the IR interface.
It is always good practice to verify the frequencies by 
going through the procedure in the section entitled 
Multi-channel System Checkout.
