6.14.6 Channel Parameters
The “CHAN PARMS” menu parameter selects the following conventional channel 
parameters that can be reprogrammed. Press Select switch to select the “CHAN PARMS” 
parameter and then rotate that switch to display the desired parameter. Then press the 
Select switch again to select it. A single beep sounds when the switch is pressed (if that 
option is enabled). The squelch control parameters are unique to the type of conventional 
channel selected (analog or Project 25).
Note
If “PASSWORD” is briefly displayed when attempting to select a parameter, see 
Section 6.14.2.
Note
If a mixed mode channel is selected, both the Rx Code (analog) and Rx NAC (P25) which 
follow can be programmed. In addition, if the Tx Type is Analog, a Tx Code is 
programmed, and if it is Digital (P25), a Tx NAC is programmed.
RX FREQ - Programs the receive channel frequency. To select the digit to change or 
move the cursor to the right, press the Select switch. Then to display the desired digit, 
rotate the Select switch. The frequency is stored after programming the last digit. If an 
invalid frequency is entered, a beep sounds, “INVALID” is briefly displayed, and the 
frequency editing mode continues to be selected.
TX FREQ - Selects the transmit frequency the same the preceding RX FREQ.
CTCSS/DCS Squelch Control (Analog Channel) - Changes the preset squelch setting 
on that channel. The default setting is “0” and values of –7 to +7 can be selected. 
Increasing this setting toward +7 causes the squelch to open sooner so that weaker 
signals can be received, and decreasing it toward –7 causes the opposite to occur.
RX CODE - Sets the receive Call Guard (CTCSS/DCS) code. The currently selected 
code is initially displayed. If required, rotate and press the Select switch to select the
