Private Call
The Private Call, also called point-to-point, or individual call, enables calling between two individuals.
No other radio can hear the conversation. This call type can be carried out in two ways:
• Duplex call (if the system allows), in TMO Mode. Both parties can speak at the same time. Start the
conversation using the S
END
key.
• Simplex call, in TMO or DMO Mode. Only one party can speak at a time. Start the conversation
using the PTT button.
When a DMO Private Call takes place, radios not involved in this call receive the channel busy
indication. The radios are identified using its radio numbers.

Ambience Listening (AL) Call
This feature allows a dispatcher to make a special call that allows listening to the conversations and
background noises within the range of a particular radio’s microphone. The call is set up without any
indication to the affected radio, and any lower priority ongoing voice call or packet data transfer may be
preempted.
After accepting the call, the radio transmits in a simplex call without any action from or indication to the
user. The Ambience Listening Call automatically ends when you initiate any voice call, switch to
Emergency or TXI Mode, or send Emergency Alarm.
