Next, press the scan button. The unit should start scanning from the lower to the higher frequencies. Pressing the Scan button again will change the direction of scanning. Each time the Scan button is pressed, "SCAN+" or "SCAN-" will be displayed on the LCD display. The scan will stop on any active frequency for the duration of the transmission. After the on frequency activity stops, the RCI-2950DX/2970DX-150 will resume scanning after about a 2 second pause. To deactivate the Scan mode, press the MAN (manual) button or turn the Squelch control counterclockwise until you hear receiver noise. The MAN button will disable the Scan function. (See FREQUENCY SCANNING, pg. 15 for more information.) Split Function4 This function enables you to split the transmit and receive frequencies by a pre-programmed amount. This feature is necessary for operation with FM repeaters. (See OFFSET FREQUENCY OPERATION, pg. 17 for more information). To split frequencies, press the MAN button and the SPLIT button to select + split frequency (transmitter higher receiver). For - split frequency, press the SPLIT button again (transmitter lower than receiver). Memory Function The RCI-2950DX/2970DX-150 can store to 10 frequencies in memory locations 0 to 9. To program a frequency into memory, follow the procedure described below: 1. Press the MAN button. 2. Press the PRG button. 3. Press the MEM button. ( "MEMORY" and "0" should appear on the left- hand side of the LCD Each press of the MEM button will advance the memory "0" to "9" . - 13 - Programming (Continued) 4. Set the desired frequency you wish to store in memory. 5. Press the ENT button. 6. Repeat the procedure to program other memory channels. Memory Channel Scanning You can scan the 10 pre-programmed memory locations by following the procedure described below: 1. Press MAN button. 2. Press the MEM button. 3. Slowly turn the Squelch knob clockwise until the receiver noise disappears. 4. Press the Scan button. The unit will scan from lower to higher memory locations. Pressing scan again will cause the unit to scan from higher to lower memory locations. 5. To stop scanning while on a memory location, press the MAN button. You can also turn the Squelch knob counterclockwise until you hear the receiver noise. Metering The segmented bars on the left-hand side of the LCD display following information: 1. S/RF METER: Provides a relative indication of transmit RF output power while transmitting or signal strength while 2. SWR METER: This function allows the checking of relative To use this function, set the unit to AM mode and push the SWR button on the front panel while holding down The bars on the meter will indicate If there is no bar, your antenna system is If several bars appear, the antenna needs adjustment. The fewer the bars, the better - 14 - Chapter 6 Frequency Scanning Frequency scanning can be achieved by either of two methods: the first method involves scanning of all frequencies between a pre-set upper and lower scan frequency. The second method permits the scanning of frequencies previously programmed in the memory locations 0 thru 9. All-Frequency scanning To allow All-Frequency scanning, the user must first program the upper and lower scan limit frequencies as follows: 1. Press the PRG (Program) key. 2. Press the SCAN key. ( "PRG SCAN+" should appear in the lower right- hand corner of the display window.) 3. Using the SHF key and the UP and DOWN arrows, select the upper scan limit frequency. 4. Press the SCAN key again. ( "SCAN-" should appear in the display window.) 5. Using the SHF key and UP and DOWN arrows, select the lower scan limit frequency, then press ENT. The upper and lower scan limits have now been programmed. To activate the scan feature, return the radio to manual operation and press the SCAN button. If the display shows "SCAN+" , the radio will scan from the lower limit to the upper limit. If "SCAN-" is displayed, the unit will scan from the upper limit to the lower limit. To change from "SCAN+" to "SCAN-" or vice versa, press SCAN. NOTE Whichever upper and lower scan limits are programmed in, are also the upper and lower operating limits of the radio. The radio will not operate above or below the scan limits last programmed in. Full band coverage can be returned by reprogramming the original band edges. - 15 - 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 por...
