64. The code number and actual code are alternately displayed (NACs are displayed in 
hexadecimal).

2 To select the displayed code and return to the normal display, press the SQ LIST 

(Squelch Code Select) switch again.

3 To check which code is selected, press the SQ LIST option switch once to display the 

current selection and then again to return to normal operation.

4 To return to the normal selective squelch codes, select “DEFAULT” in this mode. As 

previously described, the normal codes are also automatically reselected whenever 
radio power is cycled or a talk-around channel is selected.

A penalty timer may be programmed on conventional systems to prevent transmissions for 
the programmed time after the time-out timer disables the transmitter (see Section 5.3). 
The penalty timer can be programmed for the same times as the time-out timer, and timing 
starts when the PTT switch is released. If the PTT switch is pressed while the timer is 
running the timer stops, and continues when the PTT switch is released. When the penalty 
timer expires, a beep sounds and the transmitter can then be keyed.

A conversation timer can be programmed on conventional systems in addition to the time-
out timer (see Section 5.3). This timer limits that total length of a conversation rather than 
just the length of each transmission as with the time-out timer. The following is more 
information on this timer.

• It can be programmed for times up to 7.5 minutes.

• It is reset when the time between transmissions exceeds the time programmed for the 

penalty timer.

• A warning beep sounds five seconds before this timer disables the transmitter.

• When this timer disables the transmitter, a continuous tone sounds and the red transmit 

indicator turns OFF. The PTT switch must then be released until the penalty timer 
expires (indicated by a beep).
