Instructions for use
This chapter contains information regarding the use of the operating manual.
Before commissioning
Before commissioning, read and take note of
Safety Note 6188133000 and this Operating Manual 6187133001
for your radio set and familiarise yourself with the basic functions, settings and appli-
cation options.
Equipment and type designation
The funktel FT4/FT5 radio set is available in many versions.
The type designation on the type plate provides detailed information about the fea-
tures of your radio set.
Attention: Explosion-proof version
The funktel FT4 radio set is also available in explosion-proof versions.
To ensure safe handling, it is imperative that you read and follow Ex Safety Note
5010920007 for your radio set and Ex Safety Note 5010920006 for the
FT4 1700 V Ex C battery before entering an area at risk of an explosion with an
explosion-proof radio set.
To ensure proper use, take note of the associated declarations of conformity with the
EU regulations in respect of the radio sets and the components used in each case.
Designation of the Type FT4 radio sets with explosion protection (Ex), 
in the standard or Secury version:
Ex marking
Standard version => FT4 Ex C
Secury version (personal emergency signal device) => FT4 S Ex C
The designations regarding the equipment features of the radio set follow the type of
device with an Ex designation. See the graphic presentation of the FT4/FT5 device
versions on page 8.

DGNA Dynamic Group Number Assignment: The radio set is assigned
new group call numbers by radio.
DMO Direct Mode: Direct connection with other subscribers without the
TETRA infrastructure.
E2EE End-to-End Encryption
ILB / ILS

Inductive tracking beacon/system: By receiving the identification
code of a tracking beacon, the personal emergency signal centre
can determine the possible location of the radio set.
ISSI Individual Short Subscriber Identity: Individual, unambiguous sub-
scriber number of a terminal on the TETRA network.
GNSS Global Navigation Satellite System = a system for determining a
location and for terrestrial and airborne navigation by the recep-
tion of signals from navigation satellites. Well-known systems
include GPS (USA), GLONASS (Russian Federation), Galileo
(EU) and Beidou (People’s Republic of China).
Group scan-
ning
The radio set may include several scan lists. If one of the scan
lists is marked as "selected" and if the scan function is activated,
your radio set will monitor the radio traffic in all associated groups.
Consequently, you can listen to several important channels
without switching over. This feature is referred to as "Group scan-
ning". The scan lists are saved in the radio set by means of pro-
gramming.

Group A group unites several subscribers who communicate directly with
one another. Calls to a group reach all subscribers within this
group at the same time. Other subscribers cannot hear these
group calls. Group calls are possible even when not all subscrib-
ers of this group can be reached, e.g. because a radio set is
switched off.
GSSI Group Short Subscriber Identity: Call number of a group in the
TETRA network
Late entry You can participate in an already set-up group call even when you
have not received the beginning of that group call. This feature is
referred to as "Late entry". You can also use this feature when
dialling from another group or when changing the radio cell.
Local Site
Trunking.
Fallback mode: This mode comes into operation whenever an
infrastructure failure occurs but the local base station is still func-
tioning

PTT Push to talk, i.e. push before talking (PTT key)
REG The TETRA radio set registers with a TMO infrastructure (regis-
tration).
Call priority The radio set evaluates the call priority of each individual group
call if it is either a member of this group or has selected this group
as "selected group" or scans this group. When several calls are
made at the same time, you can only hear the call with the
highest priority.
SSI Short Subscriber Identity: SSI is the collective term for TETRA
subscriber numbers (subscriber identities).

TA The TETRA radio set looks for carrier frequency entries in an
internal list that are to be used for radio operation. It compares
these entries with the signals of the received TMO infrastructure
and attempts to register with the infrastructure found on the best
suited frequency.
TEA TETRA Encryption Algorithm: Encryption algorithm of the TETRA
system. Further classifications are defined in the standards
according to ETSI TR 101 053-1 to ETSI TR 101 053-4.
TETRA Terrestrial Trunked Radio
TMO Trunked Mode: Connections with other subscribers via the
TETRA infrastructure.
TS The TETRA radio set scans the pre-set frequency range for
carrier frequencies that are suitable for radio operation. It
assesses the carrier frequencies found and attempts to register
with the TMO infrastructure on the best suited frequency.
