your handset shows PTT From HS X To HS X (the first X represents the 
initiating handset number, and the second X represents your handset 
number; a maximum of four handset numbers appear).
When your speakerphone light is off (the screen shows Press and hold 
[PTT] to talk), press and hold PUSH TO TAL� on your handset. You will 
hear a chirp. Speak towards the handset.
