5.  Release the PTT button when finished speaking. 

Refer to Section 6.30 for detailed information regarding sending and receiving encrypted calls. 

The tone of received signals can be adjusted using the radio’s “Treble Menu” as follows: 

1.  Use 

 to scroll through the menu until “Treble Menu” appears. The radio’s current treble level 

setting indicates in the top line of the display. There are four levels available: low, medium, medium-
high and high. 

2.  Use 

 to increase or decrease. 

3.  Press the 

 button or wait a few seconds to return to the Dwell Display. 

The optional intercom mode gives users at multiple control heads connected to the same radio the ability 
communicate with each other without transmitting over-the-air. Turn intercom mode on and off using the 
“INTERCOM” menu as follows: 

1.  Use 

 to cycle through the available menu items until “INTERCOM” appears in the display. 

2.  Use 

 to toggle between “On” and “Off.” 

When intercom mode is turned on: 

•  Incoming voice calls will override intercom communications for the duration of the voice call. The 

radio and associated control heads will remain in intercom mode and intercom communications will 
resume when the voice call ends. 

•  “TG: INTERCOM” appears in the control head’s display when talking on the intercom. This indicates 

microphone audio is not sent out on the selected talk group; rather, it remains localized between the 
radio control positions (i.e., the control heads connected to the mobile radio). 

•  If a call exists on the currently selected talk group when a PTT button is pressed at one of the control 

heads, “TG: in use” appears in the display to indicate intercom mic audio cannot preempt the call on 
the talk group. 

 

A user at a radio with only one control head/front panel can turn intercom mode on. In 
this case, pressing the microphone’s PTT button will not send microphone audio 
anywhere. 

There are two ways of focusing voice communications by suppressing calls from talk groups in the 
currently active profile: 

1. 

No Scan. By turning scan off (selecting “No Scan” via the “ScnModeMenu”), only the selected talk group is 
audible. 

2. 

Lock Out. By locking out selected talk groups, the “chatter” of the locked-out talk groups cannot be heard. This 
focuses the user’s scanning resources to calls only on desired talk groups.
