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.
• Simplex call, in TMO or DMO Mode. Only one party can speak at a time.
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.
