Frequency Scanning (Continued)

Memory Scanning

The RCI-2950DX/2970DX-150 has 10 non-volatile memory locations which can be programmed with any frequency within the operating range of the radio. The scan function of the unit can scan the frequencies in the 10 memory locations.

The first step in utilizing the memory scan function is programming the desired frequencies into the memory locations 0 through 9 by performing the following steps:

1.With the radio operating in the manual mode, press the PRG (Program) key.

2.Press the MEM key. "PRG" should display in the lower right-hand corner of the LCD display. "MEM" should display in the upper left portion of the display. A number between 0 and 9 will display directly below MEM. This number represents the memory location currently being shown on the frequency display. Pressing the MEM key will increase the memory counter to the next memory location and the frequency in that memory location will be displayed.

3.Set the new frequency to be stored in the memory location displayed by using the SHF key and the UP and DOWN arrows. After the desired frequency is indicated, press ENT. This will overwrite whatever frequency had been previously stored at this location.

4.Repeat steps 2 and 3 for all of the memory locations to be programmed.

5.After the desired memory locations have been programmed with frequencies, return the unit to the manual mode of operation by pressing the MAN key.

6.To initiate memory scanning, press MEM and then SCAN. The display will show "SCAN+" or "SCAN-"to indicate whether the radio is scanning from the lowest to the highest memory location or vice versa. To return the radio to normal (non-scanning) operation, press the MAN key.

Chapter 7 Offset Frequency Operation

The split frequency function offsets the transmitter frequency either above or below the receiver frequency by a user-programmable amount. This is necessary for operating on FM repeaters. In the following example, the programming of a 1 MHz 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.

NOTE: FM repeaters may require that a sub-audible CTCSS tone be transmitted to gain access to the repeater. The RCI-2950DX/2970DX-150 can be equipped with an optional CTCSS encoder.

TO PROGRAM TX OFFSET:

1.Press the PRG (Program) key.

2.Press the SPLIT key. The LCD display will indicate 00000 with PRG and SPLIT showing in the lower left-hand corner of the display.

3.Using the SHF key and the UP and DOWN arrows as described earlier, program the display to read 10000.

4.Press ENT. A 1 MHz 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 to the desired receive frequency.

7.Press SPLIT. Either "SPLIT+" or "SPLIT-"will be displayed in the lower right corner of the display. If "SPLIT+" is displayed, the transmitter will be offset 1 MHz above the receive frequency when keyed. If "SPLIT-"is displayed, the transmitter will be offset 1 MHz below the receive frequency.

NOTE

When the transmitter is keyed, the frequency display will change to show the frequency being transmitted.
