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). Exact behavior depends on your service provider
settings.
• 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). Exact behavior depends on your service
provider settings.
NOTICE: To end the Private Call if audio was switched to the speaker, press ON/OFF/END/
HOME key.
To answer a Private Call, use one of the following methods:
• Press the PTT button.
• Take the Fist Microphone or Telephone Style Handset off hook. If the Handset is off hook, the
radio’s external speaker mutes and the Handset’s internal speaker activates.
• Press the SEND key on the control head. Audio is routed to audio input devices in the following
order, depending on their availability:
1 A visor microphone.
2 A microphone of the device that is off hook.
3 A microphone that was last in use (if two devices are off hook).
