Microphone 

 

1. PTT SWITCH:  The Push-To-Talk (PTT) switch controls the transmit 

and receive function of the radio. Push to transmit and release to 
receive. 

2. REMOTE UP/DOWN SWITCH: The digit on the frequency display 

above the SHF “cursor” can be stepped up or down by pushing either 
of these buttons. 

 

For best results, the user should select a low-impedance dynamic type 
microphone or a transistorized microphone.  

 

The microphone should provide the functions shown in schematic below.

Frequency Selection

 

Frequency selection in the RCI-5054DX/5054DX-100 can be

 accomplished 

using any one of the following three methods: 

 

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

the 

(UP)/

(DOWN) keys located on the front panelTo accomplish 

this, press the SHF key until the display cursor on the frequency 
display is positioned under the frequency digit that is to be changed.  
Use the”

  key  to increase the number.  Press the “

  key to 

decrease the number. Perform the steps described above for each digit 
until the desired frequency is displayed in the LCD frequency display 
window. 

 

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

key and the FREQUENCY select knob located on the front panel.  Use 
the  SHF key in the manner described above to select the digit to be 
changed.  Then rotate the FREQUENCY selector 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 

key and the remote UP and DOWN buttons located on the microphone.  
Frequency selection by this method is accomplished in the same 
manner as with the  

  key and the “

  key on the front panel 

keypad.  

 

Sometimes when receiving more than one station on a fixed frequency 
such as on a “Net” or “round table” operation, it is convenient to be able 
to vary the receive frequency slightly without changing the transmit 
frequency. To do this, rotate the clarifier control while an off frequency 
station is transmitting. You can vary the receiver frequency by ±2.5 KHz 
for clearest voice reception.  The clarifier can be optionally modified to 
vary both Transmit and Receive frequencies together.
