Frequency selection for the  RCI-5054DX  is simple. Select the desired 
operating frequency by rotating the Frequency  Selector, or using the 
UP/DOWN buttons on the front panel or the microphone. Press the LOCK 
button to lock the selected frequency . This will disable the Frequency 
Selector and the UP/DOWN buttons on the front panel of the microphone. 
Repressing the LOCK button unlocks the frequency. 
Use the SHF button to set the step frequency in either 100Hz, 1KHz, 10KHz, 
100KHz  or 1MHz increment. The frequency step is indicated by a small 
triangle directly under the corresponding digit on the frequency display. 
 

 

To Select an operating mode on your  RCI-5054DX, simply rotate the MODE 
selector, and place it in the desired operating mode position. The PTT switch 
on the microphone controls the transmit and receive of your radio. 
 

  

This feature allows the adjustment of the RF output power continuously over 
the range of 1W through 25W.

Frequency selection in the RCI-5054DX can be accomplished using any 
three of the following methods : 

 

1. The first method of frequency selection uses the SHF (Shift ) key and the 

UP and DOWN arrows. To accomplish this, press the SHF button until the 
cursor arrow is positioned under the digit of the frequency that is to be 
changed. Then use the UP arrow to Increase the number. If a decrease in 
frequency is desired, press the DOWN  arrow. Perform the steps 
described above for each digit of the frequency is displayed in the LCD 
display window. 

 

2.  The second method of frequency selection is performed using the SHF 

button and the frequency select knob located above the microphone jack. 
Use the SHF button in the manner described above to select the digit to 
be changed. Then rotate the frequency select knob clockwise to increase 
the frequency and counterclockwise to decrease the frequency. 

 

3. The third method of frequency selection is through the use of the SHF 

button and the channel UP and DOWN button located on the microphone. 
Frequency selection by this method is accomplished in the same manner 
as with the UP and DOWN arrows on the key pad. The only difference  is 
that the channel UP and DOWN buttons  on the microphone are used. 

 

Once a signal has been detected on a particular frequency while in receive 
mode, it may be necessary to slightly change the frequency to provide the 
best audio. This is accomplished by rotating the clarifier control, varying the 
frequency by + 0.5 KHz. After fine tuning, press the LOCK button to lock in 
the frequency at the point of best reception.
