Assistance Call

duplex).

Call Modification

Call Modification is a feature that allows your service provider to modify the call in order to optimize it and adjust to
a current situation.
Modification can cover:
• Call priority — modified during call setup.
• Call type — modified during call setup.
• Call encryption — modified during an ongoing call (but not in the transmission phase).
When the call is modified, your radio displays Call Modified message.
When a recently modified call requires the PTT button to transmit, your radio displays Call ModifiedUse PTT.
All modifications are made by your service provider and the radio only follows them. You have no influence on
ongoing call modifications.
When call priority is changed to emergency:
• The display indicates that an Emergency Group Call has been received.
• The radio plays a special audio alert.
Note: If a Group Call is modified into an Emergency Group Call, no emergency related features are
triggered.
If call modification requested by your service provider cannot be followed by the radio (due to its settings), the radio
rejects it and displays Service Not Available message.
