Chapter 5 Programming
Receive Scanning
The receive scanning feature helps locate active frequencies within
a preprogrammed band segment anywhere on the 6 Meter band
(refer to SCANNING, page 16). To begin scanning, slowly turn the
Squelch control clockwise until the receiver noise disappears.
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 press of the
Scan button displays "SCAN+" or "SCAN-" 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-
5054DX will resume scanning after about a 2 second pause. To
pause the Scan mode, turn the Squelch control counterclockwise
until you hear receiver noise. To deactivate the scan function,
press the MAN button.

Split Function
This function enables you to split the transmit and the receive
operating frequency by a pre-programmed offsett. This feature is
necessary for operation with FM repeaters. (See OFFSET
FREQUENCY OPERATION, pg. 18 for more information). To split
frequencies, press the MAN button and the SPLIT button to select
+ split frequency (transmitter higher than receiver). For - split,
press the SPLIT button again (transmitter lower than receiver).

Memory
Function
The RCI-5054DX can store up 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.

Metering
The segmented bars on the left-hand side of the LCD display
provides the following information:
provides the following information:
1. S/RF METER: Provides a relative indication of the transmit RF
output power while transmitting or signal strength while receiving
2. SWR METER: This function allows the checking of relative
SWR. To use this function, set the unit to AM mode and push
the SWR button on the front panel while holding down the PTT
switch on the microphone. The bars on the meter will indicate
approximate SWR. If there is no bar, your antenna system is
well matched. If several bars appear, the antenna needs
adjustment. The fewer the bars, the better the match.
