The radio provides with the possibility to view the number of used and free address book entries.
The address book is also accessible through PEI. Using the PEI enables you to read, write, and modify contact list

Call History

A call history stack is provided which consists of the following:
• Last dialed numbers
• Missed call numbers
• Answered (Received) call numbers
Additionally for the recent calls the time when a call was established and the call duration is available.
The Call History stack holds private TETRA IDs as well as phone and PABX numbers.
Numbers from the stack may be viewed, selected, and called. However, outgoing duplex calls from Recent Calls list
display in DMO are not allowed. When you scroll through the lists, the entries appear in the opposite order (the most
recent entry is shown first).
When a call is made to a number that exists in the last dialed list, this number is not duplicated in the list and is
moved to the beginning of the list. However, a missed call and received entries are duplicated in the corresponding
call list.
The call history lists are available after next power-up.
You can save a number from the call history stack to the address book.

Group Call

The group call service enables the radio to communicate with a group of other TETRA radios using point to multi-
point operation. This service is available in both TMO and DMO. You can initiate a new group call to the selected
talkgroup or talk back to the existing group call by pressing the PTT button.

Programmable Talkgroups

The radio offers a talkgroup list facility. Each talkgroup entry contains a TETRA group address and may be
associated with a name tag. The talkgroups can be defined in the codeplug as per the radio capabilities. Talkgroups
are configured separately for TMO and DMO modes. To program a talkgroup in TMO define its name and GSSI. To
program a talkgroup in DMO define its name, GTSI and frequency. The radio operator can select a talkgroup which
has an associated TMO or DMO frequency depending on the mode selected. When switching between the TMO and
DMO modes the last active talkgroup is selected. However the required talkgroup can be mapped in CPS. In such a
case a corresponding talkgroup is automatically selected during mode switching, irregardless of the previously
selected talkgroup.
Note: Neither the group name nor the corresponding group address can be edited using the radio MMI.
