made by pressing the select button or the PTT. Upon sending the Message, the radio will 
wait until the Message has been sent, and then display the appropriate message for 
whether it was received successfully or not. If the Message was not sent successfully, the 
radio will return back to the Message menu to allow the user to try again or try a different 
Unit ID or Message.

When a radio receives a Message, it will flash the green LED next to the toggle switch, 
sound a Message Received Tone, and display three flash messages (“Msg Rcvd”, Unit ID 
of sending radio, Message Alias or ID received). The Message is cleared upon any button 
press when not in the menu. When in the menu, the Message is only cleared by pressing 
the Back/Clear button.

The status feature allows you to send your current status to your dispatcher. Up to 255 
status conditions can be preprogrammed, and they are identified by an alias. If the Status 
option switch is programmed, status conditions are sent as follows:

1 Momentarily press the Status option switch. The alias of the current status condition is 

displayed. (STATUS can also be selected from the menu.)

2 To change the current status, rotate the Select switch until the desired status is 

displayed. Then press the Select switch to accept that status. A single beep sounds 
when the switch is pressed (if that option is selected). One of the following conditions 
then occurs:

- If five beeps sound and “ACK RECVD” (Standard Control Head) or “Ack Received” 

(Lightning Control Head) is displayed, the status was received and acknowledged by 
the system.

- If after five tries the message is not acknowledged, a tone sounds and “NO ACK” 

(Standard Control Head) or “No Acknowledge” (Lightning Control Head) is 
displayed.
