Receiving a Group Call

When receiving a group call, the radio will establish it 
automatically. After the call is established successfully, 
the radio will give ring indication and display the icon 

 on the LCD as well. 

Voice Communication

 

General  Group  Call:  After  a  group  call  is 
established, either of the calling or called party can 
hold  down  the  PTT  key  to  speak  while  the  radio 
displays 

PTT Enable

 on the LCD. The radio will 

display  the  icon 

  during  transmission  and  the 

icon 

 upon receipt respectively. 

 

Broadcast  group  call: After  the  call  is  established, 
only the calling party can talk by holding down the 
PTT key. During transmission, the calling radio will 
display the icon 

 

on the LCD. The called party 

can only receive the voice. 

Late Entry

With the Late Entry feature, a group member can join 
an in-progress group call without any operation. 
The Late Entry feature is designed for the following 
situations: 

 

The radio moves within the coverage area after the 
group call is established. 

 

The  radio  is  turned  on  after  the  group  call  is 
established. 

 

The  radio  is  busy  with  other  call  services  when 
the  group  call  is  established. After  such  other  call 
services end, this group call is still in progress. 

 

The  signal  of  the  base  station  recovers  after  the 
group call is established. 

 

The radio is added to the group after the group call 
is established. 

End of Communication

The call will be terminated when any of the following 
situations occurs: 

 

Neither party holds down the PTT key to talk before 
the  preset  time  period  expires.  (except  in  the 
broadcast group call) 

 

The  call  duration  exceeds  the  time  preset  by  the 
dealer. 

 

The  calling  party  ends  the  in-progress  call  (if  the 
called  party  ends  the  call,  the  called  radio  will 
exit  on  its  own  only,  and  can  rejoin  via  Late  Entry 
feature). 

 

The base station signal is lost. 

 

A  pre-emptive  call  or  emergency  call  occupies  the 
channel. 

Emergency Call

In case of emergency, you can use this feature to ask 
for help from your companion or the control center. 
The Emergency Call has the highest priority which can 
terminate the ongoing calls with lower priorities on the 
current channel. You can make emergency call even 
when your radio is transmitting or receiving. 
This feature needs to be configured and enabled by 
your dealer. Please refer to the corresponding Feature 
Book for details.
