TOP DISPLAY : -EA RCVD in orange/amber
-alternates between EA RCVD and ALPHA NUMERIC ID of radio transmitting EA
HOLDS DISPLAY FOR 8 SECONDS

20
Q

When a member transmits an EA depresses PTT..

A

receiving members will observe ORANGE BAND with EMERGENCY CALL appearing on main display with UNIT and POSITION (similar info will SCROLL ACROSS TOP DISPLAY
