Late Entry
After a group call is established, it allows other group members to join this call.
Late Entry may occur in any of the following situations:
n
The radio is powered on.
n
The Group Call Selector knob is rotated to the group in operation.
n
The radio exits from another group call.
n
The radio is within the communication coverage of this group call.
Group Call Combination
After a group call is established, the user can input the group ID or select the group
from Group Call Contact to join the current group call.
Voice Communication
After a group call is established, either the calling party or the called party can make a
voice call only if the PTT key is free. The PTT key is free when the radios of both parties
display the PTT Admit screen.
Conversation Limit
When a group call is established, both the calling party and the called party will display
the call duration in real time.
At the Calling Party, a countdown timer is displayed showing the remaining time for a
call. The time period is programmed by the dealer. The group call will be terminated
automatically when the preset time expires.
At the Called Party, the actual communication time is displayed. The timer starts
counting once the called party joins the group call. If the called party exits from this
call and then rejoins it later through the late entry method, the counter restarts.
Ending a Call
The voice communication will be terminated when one of the following situations
occurs:
n
No operation (PTT key press) is performed within the preset time (pro-
grammable).
n
The preset time expires.
n
The calling party ends the ongoing call.
n
Signal of base station is missing.
