8 BASIC FUNCTIONS
8.1 Group Calls
Group calls will enable you to communicate with a group of users that are allowed to
participate in the communication. Select GRP mode with the soft key ‘Mode’.
A group call is always semi-duplex with direct signalling: the group selected on screen is
directly connected by pressing PTT, and it is not possible to listen and speak at the same time.
The groups are organised in ranges (or folders). Each range can have several groups and
their distribution is established by programming.
To select the range and group, use the navigation keys .
Alphabetic search will only be applied to the groups included in the selected range.
Once the user has selected one of the ranges, it will only be possible to move through the
groups included in that range. The groups will be sorted alphabetically within each range. The
selected range / group is displayed on the screen.
To change the range, press the soft key ‘Range’.
When a group has been selected, its status will be displayed on screen for a few seconds. The
call to this group will proceed if the group is available. If it isn’t, pressing PTT will display the
message “Non-valid group”.
The user must keep the PTT key pressed to send the call, and the rest of the users in the
group will listen directly.
The STS led will turn red (transmission) or green (reception).
