You can call anyone who has a radio with DSC functionality. You can set the priority level of the DSC call to routine, safety, urgency, or distress. Choose:

•ROUTINE to make a routine call

•SAFETY to send safety information

•URGENCY only when there’s a serious situation or problem that could lead to a distress situation

•DISTRESS only when there’s a distress situation.

2.The cursor is at ROUTINE. Press ENT or press the rotary knob to make a routine call or select to another priority level.

3.The cursor is at MANUAL NEW. Press ENT or press the rotary knob to call a person who’s not in your buddy list; otherwise select the name of your buddy.
