Chapter 6 Frequency Scanning
Frequency scanning can be achieved using one of two methods : the first
method involves scanning of pre-programmed memory channels; the second
method permits the user to scan all frequencies between a pre-set upper
and lower scan limit. Both methods of frequency scanning follows.

and lower scan limit. Both methods of frequency scanning follows.
All-Frequency scanning
To allow All-Frequency scanning, the user must first program the upper and
lower scanning limits. The scan limits are simply the highest and lowest
frequencies that will be scanned. To program these limits, perform the
following steps :
lower scanning limits. The scan limits are simply the highest and lowest
frequencies that will be scanned. To program these limits, perform the
following steps :
1. Press the PRG (Program) key.
2. Press the SCAN key. ("PRG SCAN+" should appear in the lower right-
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.
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,
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.

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
When programmed, the upper and lower scan limits will also act as the
upper and lower operating limits of the radio. The radio cannot now be
programmed to operated above or below the scan limits.

Memory Scanning
The RCI-5054DX has 10 non-volatile (i.e., memory resident) memory
locations which can be programmed with any available frequency within the
operating band of the radio. The scan function of the unit can be
programmed to scan these memory channels. The radio will then scan only
those memory channels. The radio will then scan only those memory
channels which have been programmed.
locations which can be programmed with any available frequency within the
operating band of the radio. The scan function of the unit can be
programmed to scan these memory channels. The radio will then scan only
those memory channels. The radio will then scan only those memory
channels which have been programmed.
The first step in utilizing the memory scan function is programming the
desired frequencies into the radio memory. This can be accomplished by
performing the following steps :
desired frequencies into the radio memory. This can be accomplished 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 be displayed in the lower right-hand
corner of the LCD display. In the upper left portion of the display, "MEM"
should be displayed. Directly below MEM, a number between 0 and 9 will
be displayed. This number represents the memory location currently
being displayed. Pressing the MEM key will increase the memory counter
to the next memory location and the contents of that memory location will
be displayed.

the MAN key.
6. To initiate memory scanning, press MEM and then SCAN. As previously
discussed, 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.
