Frequency Selection
Frequency selection in the RCI-5054DX 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 panel. To
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. Rotate the FREQUENCY selector
clockwise to increase the selected digit or counterclockwise to
decrease the selected digit.
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.
