Single mode scanning 

 

Turn off the transmitter(s). 

 

Press the INC key to initiate a scan.  

 

While the RX-4 is scanning, the frequency being examined is displayed 

on the bottom half of the screen and a graphic map of the RF that is 

found will be displayed with a vertical line extending up from the 

baseline. The length of the line indicates the level or strength of the 

found RF at that frequency. 

 

Pressing the MENU key while scanning will abort the scan. 

 

Selecting a frequency 

When the scan is complete a suggested frequency will be shown, and a 

vertical blinking line will be drawn on the display.  

At that point:  

 

Press the left RECEIVER key to select the desired receiver 

(RXA, RXB, RXC, RXD). Please note if the receivers are in single mode then RX A and RX C would be used. 

 

Press the INC key to accept the frequency. 

 

Press the DEC key to select another frequency. 

The scan result is always available as long as there is valid scan data. So, this screen can be revisited, and different 

frequencies can be chosen. 

 

Set Bandwidth 

 

 

 

                           

 

The bandwidth range will set how wide the operating range will be on either side of the center frequency. The 

bandwidth can be adjusted from 4 to 40 MHz. 

 

Test Tone Output 

 

 

 

 

 

From the tone menu a 1K test tone can be enabled. The tone will be outputted from the TA5 connectors. This 

is used to set levels and check routing. 

Pressing the INC and DEC key will cycle through the different tone settings. 

 

OFF - 

No tone is being outputted.

 

 

-20dBFS -

Tone is simultaneously sent to all 4 outputs at -20dBFS. 

 

CHAN-ID -

Tone is sequentially sent to each channel one at a time at -20dBFS. 

 

+0dBFS -

 Simultaneously sends tone to all 4 channels at 0dBFS (full scale)
