The receive scanning feature allows you to locate active frequencies in the 
entire band segment. To begin scanning , slowly turn the  Squelch control 
clockwise until the receiver noise disappears. Next, press the scan button. 
The unit should start scanning from the lower to the higher frequencies. 
Pressing the Scan button again will change the direction of scanning. When 
the Scan button is pressed ,"SCAN+" or "SCAN-" will be displayed on the 
LCD display . The scan will stop on any active frequency for the duration of 
the transmission. When the transmission stops, the RCI-5054DX will wait 
approximately 2 seconds before it resumes scanning. If you want to 
deactivate Scan mode while it's scanning, press the MAN (manual) button or 
turn the Squelch control counterclockwise until you hear the receiver noise. 
The  MAN button will disable the Scan function. (See FREQUENCY 
SCANNING, pg. 15 for more information.) 

 

 

This function enables you to split the transmit and receive frequencies for 
FM repeater operation. To split frequencies, press the MAN button and the 
Split button to select + split frequency. If you want - split frequency, press 
the Split button again. If + split is selected, the transmit frequency will be 
higher than the receiver frequency. If - split is selected, it will be lower than 
the receive frequency. (See OFFSET FREQUENCY OPERATION, pg. 18 for 
more information.)  

 

 

The RCI-5054DX can store up to 10 channels (from 0 to 9). To program a 
frequency into memory , follow the procedure described below : 
1. Press the MAN button. 
2. Press the PRG button.

 

3. Press the MEM button. ("MEMORY" and "0" should appear on the left-

hand side of the LCD display. Pressing the MEM button will advance the 
channel number from "0" to "9".)

4. Select the desired frequency you wish to store in memory. 
5. Press the ENT button. 
6. Repeat the procedure to program other memory channels. 

 

 

 

You can scan and select any of the 10 programmed frequencies by following 
the procedure described below: 

 

1. Press MAN button. 
2. Press the MEM button. 
3. Slowly turn the Squelch knob clockwise until the receiver noise 

disappears. 

4.Press the Scan button. The unit will scan from lower to higher frequencies. 

Pressed again, the unit will scan from higher to lower frequencies. 

5. To stop scanning a certain channel, press the MAN button, or turn the 

Squelch knob counterclockwise until you hear the receiver noise. 

 

 

 

The meter built into your RCI-5054DX on the left-hand side of the LCD 
display provides the following information: 

 

1. S/RF METER : In transmit mode it provides a visual indication of transmit 

RF output power and received signal strength on the receive mode.  

2.  SWR METER : This meter enables you to check SWR. To use this 

function, set the unit to AM mode and push the SWR button on the front 
panel while holding down the PTT switch on the microphone. The bars on 
the meter will indicate antenna matching. If there is no bar, your antenna 
system is perfectly matched. If several bars appear, the antenna needs 
adjustment. The fewer the bars, the better the match.
