3.4.5 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.
Interaction with the accessories:
• Fist Microphone — during the Private Call, if you hang the microphone into the clip the call ends or the
audio switches to the speakers (if connected).
• Telephone Style Handset — during the Private Call, if you hand the handset into the holder, the call ends or
the audio switches to the speakers (if connected).
3.4.6 Private Call With Presence Check
This feature allows you to see if the calling party is available.
When this feature is enabled, you can only initiate a Private Call if the called radio is present on the same channel
and responds with a presence check acknowledgement. Otherwise your radio displays
Party not available
.
3.4.7 Communication through Repeater
Radios that cannot communicate directly between each other in DMO Mode, can do it through the repeater that is
attached on the same talkgroup. This connectivity is used to enhance the radio DMO area.
