Offset Frequency Operation; Circuit Description - Ranger RCI-2985DX Manual

The split frequency function offsets the transmitter frequency either above or below the receive
frequency by a user programmable amount. In the following example, programming of a 100 KHz
offset will be described. Before attempting to program the offset frequency, ensure that the radio is
operating in the manual mode by pressing the MAN key.
(1) Press the PRG (Program) key.
(2) Press the SPLIT key. The LCD display window will display "00000" with "PRG" and "SPLIT"
being displayed in the lower left hand corner.
(3) Using the SHF key and the ( ) Up and ( ) Down arrows as described earlier, program the
display to read "010000".
(4) Press ENT. A 100 KHz offset has now been programmed into the radio.
(5) Return the radio to manual operation by pressing the MAN key.
(6) Using the SHF key and the ( ) Up and ( ) Down arrows as described previously, set the radio
for the desired receive frequency.
(7) Press SPLIT. In the lower right corner of the display, either "SPLIT+" or "SPLIT-" will be
displayed. If SPLIT+ is displayed, the transmitter will be offset 100 KHz above the receive
frequency when keyed. If SPLIT- is displayed, the transmitter will be offset 100 KHz below the
receive frequency.
(8) To return the radio to simplex operation (i.e., same transmit and receive frequency), press the
MAN key.

The FM repeaters may require a subaudible (CTCSS)
tone be transmitted to gain access to the repeater. The
RCI-2985DX / RCI-2995DX is not factory equipped with
a CTCSS encoder/decoder.
When the transmitter is keyed, the frequency display will
change to show the frequency being transmitted.
