Battery
For your safety, inspect the battery regularly for any signs of damage,
such as cracks or surface damage caused by an impact or the battery
being dropped. Fit a new battery if there are any signs of damage.
Warning: Risk to personal safety. Sepura TETRA radios have been
tested and certified using Sepura approved batteries. The use of non-
approved batteries may damage the product, will result in non-
compliance with regulatory requirements, compromise the product
safety ratings including SARS, reduce the length of operating time and
will invalidate the product warranty.
Checking the battery charge
Always check the amount of battery charge before lengthy periods of
operation. A fully charged battery should provide continuous operation for a
full shift, depending on a number of operational factors such as how the
radio is operated, the operating environment (temperature and network
signal strength) and the condition of the battery. When the radio is powered
on, the amount of charge remaining may be displayed as a percentage (%) on
the screen.
Battery charge indicators
Abattery meter appears on the status line at the top of the radio display. The
meter consists of 4 bars comprising 8 segments that fill and empty
corresponding to the estimated amount of charge remaining.
Icon Description
Battery is fully charged.
Battery is 50% charge capacity.
Battery has >12% charge remaining.
Battery charge less than 12% charge remaining.
User Guide 5
Optimising battery life
A fully charged battery should last a full shift (approximately 12 hours) but
this depends on a number of operational factors, such as how the radio is
operated, the operating environment (temperature and network signal
strength) and the condition of the battery.
Try the following to help you optimise battery life on a daily basis:
Ensure that batteries are fully charged at the start of a shift.
Decrease the amount of time the backlight stays lit between key presses
(see Adjusting the backlight on page 40).
Keep your speaker audio volume to a minimum (see Adjusting the volume
on page 37).
Reduce the length of time the radio is transmitting and keep DMOor
telephone type calls to a minimum because they cause higher current
consumption.
Shorten the GPS reporting intervals if enabled (see GPS reporting options on
page 124).
6SC20 series – 04/2016
Charging the battery
Your radio is powered by a rechargeable battery. The battery may be
recharged many times but it will eventually need replacing to ensure
continuous maximum performance from your radio.
First time battery charging
New batteries (Standard battery part no. 300-01174 and High Capacity battery
part no. 300-01175) are supplied in 'storage mode' which means they have a
minimum amount of charge for storage purposes. Before using a new battery
for the first time it must be fully charged to reactivate it. If the battery is used
before it is reactivated (fully charged) the radio may not power on, or may
indicate a low battery status icon or low level of charge.
Battery chargers
Only use Sepura approved battery chargers. Use of non-approved chargers
may not fully charge the battery or damage it. Always read the user
documentation supplied with the charger for additional safety instructions
and how to use it.
Charging methods
The radio may be powered on or off during charging.
Attach the Charger cable to the sDAC connector at the base of the radio or
place the radio with battery attached into a charging dock. If the battery is
charged attached to the radio, and the radio is powered on, an indication of
the remaining time to fully charge the battery is displayed (in hh:mm format).
During charging, the tri-coloured LED on the radio indicates the charging
progress and the charging icon appears on the status line, providing there is
sufficient charge in the battery to support this function.
Status LED Description
Flashing
Orange
Battery temperature is either too hot or cold to
commence charging.
Solid Orange Charging in progress.
Solid Green Charging complete.
Solid Red Battery has failed to charge and may be not be chargable.
Contact your service provider or Sepura.
User Guide 7
The battery may be charged separately from the radio using a battery-only
charger.
Charging a 'flat' battery
If the battery is completely 'flat' (without charge) during storage or after a
long period of non-activity, it may fail to recharge or stop charging after 20
minutes. If this happens, disconnect and then reconnect the charger (or
power off the charger, then power on) to reset the battery.
Avoid charging a flat battery attached to a radio. During charging, the radio
will attempt to power on when the battery charge reaches a certain capacity,
which will drain the battery of its charge.
Fitting the battery
Ensure that the Smart/microSD card compartment cover is securely latched
before fitting the battery.
If a belt clip is fitted to the radio, lift the belt clip before attempting to fit the
battery. Do not attempt to insert the battery into the battery compartment
sideways under the belt clip. This may result in damage to the radio and the
belt clip.
To attach the battery, insert the battery into the battery compartment as
shown. Press the battery downwards until it clicks into position.
Removing the battery
Always power off before removing the battery.
8SC20 series – 04/2016
Push the safety latch on the bottom of the battery. Lift the battery upwards
and remove.
Using Sepura approved batteries

has a number of battery management features that only work when a genuine
Sepura battery is fitted:
the remaining battery charge appears as a percentage when your radio is
powered on [customisable];
battery meter icons, showing the remaining battery charge;
a low battery warning appears when charge is low; and
you can check battery information, such as its authenticity, remaining
charge and serial number [customisable] (see Getting information about your
battery on the next page).
If your radio detects a non-approved battery, the message "Unidentified battery
-powering down" appears. The message is cleared by pressing any key.
If your radio detects a non-approved battery, the message "Unidentified
battery" appears.
If your radio detects a non-approved battery, the message "Unidentified battery
-powering down" and your radio powers off.
Caution: Non-approved batteries may not have inbuilt safety protection
features, and could potentially damage your radio (invalidating your
warranty) and affect your radio's safety and IP compliance ratings.
User Guide 9
Getting information about your battery
You can see information about the battery attached to your radio, such as the
remaining battery charge, whether the battery is authenticated (a genuine
Sepura battery) and the battery serial number [customisable].

Emergency operation
Emergency operation is available in TMO and DMO if the radio is in service.
If your radio is customised for Gateway and Repeater modes, it will make an
Alarm call in TMO. If it cannot make the call in TMO the radio will
automatically switch to DMO to make the call.
The red button on the top of your radio is programmed to initiate an Alarm
call at any time when your radio is in operation. This button is known as the
Emergency Button.
Your radio may be customised to perform one or more of the following:
Initiate an Alarm call set up to one or more pre-defined users (typically to
your dispatcher and other members of your talkgroup) and/or;
Send an Emergency Status message to an individual, the dispatcher or a
talkgroup and/or;
Send a position report (GPS dependent).
If you are working in RF sensitive areas and have enabled Transmit Inhibit,
prohibiting radio transmission, initiating an Alarm call will override the
Transmit Inhibit feature and the Alarm call will be transmitted.
Your service provider or organisation can provide information on how your
radio is customised for Alarm calls and how to operate your radio in
emergency situations. If you are working in a sensitive environment your
radio may be customised for Silent Alarm calls where audible and display
alerts are disabled, or your radio may be customised for Live Microphone that
allows you to call for assistance hands-free without pressing the PTT button.
Silent Alarm Call
If you are working in sensitive environments where the audible and display
alerts associated with an Alarm call are inappropriate, your radio can be
customised to make a Silent Alarm call (without acoustic or screen alerts).
Silent Alarm calls cannot be activated when operating in Lone Worker or
Man Down modes.
User Guide 33
When a Silent Alarm call is made, the radio displays the Home screen with
the talkgroup associated with call. During the call you may navigate away
from the Home screen.
Live Microphone feature
Your radio may be customised with the Live Microphone feature. This feature
allows you to broadcast a call for assistance hands-free for a specified period
of time and without having to press the PTT button. The radio automatically
cycles between transmit and receive communication during a programmed
period of time (seconds). Live Microphone is cancelled when the time expires
or by pressing the PTT button.
Making an Alarm call
You can still make an Alarm call if the keypad is locked.
To make an Alarm call
1. Press and hold (2 seconds) the Emergency button; a confirmation beep
sounds.
2. Release the button and speak into the microphone.
During an Alarm call:
the microphone is ‘live’ for a programmed period (seconds) allowing you
to speak hands-free without pressing the PTT button (customisable)
the LED illuminates solid red
your radio sounds audible tones
a large emergency symbol appears on the screen
your identity and talkgroup appears on the display of those receiving the
Alarm call
34 SC20 series – 04/2016
Receiving an Alarm call
An Alarm call overrides any existing calls on the talkgroup.
You know you are receiving an Alarm call when:

Clearing an Alarm call
You can only clear an Alarm call that you have initiated.
To cancel the Alarm call, press the Call Clear key, the Clear context key or
the Cancel/Home key. Alternatively, press and hold the Emergency button (2
seconds).
Warning: Depending on which network is being used, if the TETRA
Alarm call is a group call, then although both of the TETRA Alarm call
exit functions will clear the TETRA Alarm call on the call originator’s
radio, it will not remove the alarm from the system. It should also be
noted that those radios alerted to the emergency may, depending
upon the infrastructure configuration, remain in the TETRA Alarm call
condition until the dispatcher clears the call from the system.
When the Alarm call is cancelled, your radio returns to the talkgroup that
was selected before the call was initiated.
Power on Alarm call
If your radio is powered off, press and hold (3 seconds) the Emergency
button to power on and initiate an Alarm call. Any customised Welcome

Talkgroups and folders
Your radio can only participate in calls with talkgroups it is attached to via
the network. You can only initiate calls to other radio users in the selected
talkgroup. (However, when ongoing calls are detected on any talkgroup your
radio is scanning you can join in by pressing the PTT.) When your radio is
powered on it re-selects either the default talkgroup or to your last selected
talkgroup.
Talkgroups are pre-programmed onto your radio. Each talkgroup typically
contains users who have a similar role or who are within a distinct location or
who provide a service that you would use.
Talkgroups are organised into folders to help you quickly select one that is
applicable to your environment or situation. A top level folder can have a
number of sub-folders, similar to a folder structure on a computer. A folder
can contain both folders and talkgroups. The folders available depend on the
customisation of your radio; various ‘special’ folders are also programmed
into your radio (see Special folders on page 51).

User Guide 51
UDSL—user-defined scan list(s), see User Defined Scan Lists below. A list of
talkgroups which you can modify yourself. If you select a UDSL instead of a
specific talkgroup your radio scans all the talkgroups in that UDSL. Until a
UDSL is selected its talkgroups are not scanned for activity. For more
information see User Defined Scan Lists below.
Favourites—frequently used talkgroups that can be added to the folder
during customisation or added by the user.
All—contains every talkgroup programmed into your radio. This includes
all talkgroups in the ‘standard’ folders created to contain your talkgroups
and those in all special folders (but not those in DGNA).
User Defined Scan Lists
A User Defined Scan List (UDSL) is a list of talkgroups which are either fixed,
or user-definable. Until a UDSL is selected the talkgroups it contains are not
scanned and your radio cannot receive calls from them. Your radio can have
a maximum of 20 UDSLs, and up to 10 talkgroups can reside within each
UDSL.
If you select a UDSL (in the same way as you select a talkgroup, see Select a
talkgroup on page 49):
the talkgroups it contains are scanned, allowing your radio to receive calls
from any of the talkgroups in the UDSL
the UDSL icon is displayed in the right hand corner of the radio
display
one talkgroup in the UDSL becomes the ‘selected talkgroup; when you
initiate calls they are made to this talkgroup (providing that there is no
activity on any other talkgroups being scanned).
Each talkgroup in a UDSL can have up to three different levels of user-
definable group scan priorities which are used by your radio when deciding
which call to follow when a call on one talkgroup is active and a call on
another talkgroup is received. The scan priority of each talkgroup in a UDSL
is shown at the right hand side of the screen as (High), (Normal) or
(Low). You can designate a selected talkgroup in each UDSL. You can add
and remove talkgroups from a UDSL.

Contacts
Details of regularly used contacts are stored in a phone book. The phone book
has a series of folders labelled Menu,Search,All and Personal. Your radio may
have additional folders containing contacts programmed into your radio
during customisation.
The Personal folder contains contacts you create (personal contacts). This
folder only appears when you create your first personal contact. The All
folder contains both personal contacts and contacts programmed into your
radio.
Each contact can have up to six associated numbers. A maximum of 6000
numbers can be held in the phone book. The icon next to each contact
indicates the dial mode, a radio or to a telephone, of the first
number associated with it.
Contacts are arranged in a series of up to 64 folders including the following:
All — contains all contacts in the Phone book
Menu — contains options to create and delete contacts in your Personal
folder
Search — allows you to search the entire Phone book for contacts and
numbers. Initially lists the names of all the folders in the phone book and

Calls
The various types of voice and data calls that are supported by your radio,
and the acoustic and visual alerts that accompany a call, depend on your
radio's customisation.
Call types
Sepura radios support the following voice- and data call types:
Voice call types
Voice call type Description
Group
A call between you and a group of other radio users in
your attached talkgroup. A group call is always a half-
duplex call. Users can join and leave the call at any time.
Group calls are initiated by pressing the PTT button. See
Talkgroups and folders on page 46.
Individual
A call to another user or dispatcher in the TETRA
network, or to an external telephone subscriber via the
Gateway. full-duplex and half-duplex calls are
supported.
Individual calls to outside the TETRA network can be
made between a terminal or a dispatcher and a telephone
subscriber in a network to which the TETRA network
has a gateway interface. These calls are always full-
duplex.A full-duplex call is one in which both parties can
speak at the same time. The Select/Send and
Cancel\Home keys are used to initiate and end calls.
In a half-duplex call only one person can speak at a time
and needs to press the PTT button.
PBX
A call to a user on a private branch exchange (PBX). This
call needs to be set up by your service provider and
allows you to call a person by dialling their extension
number (preceded by a programmed digit used to dial
the exchange).
PSTN A call to a user on a the public switched telephone
network (PSTN).
60 SC20 series – 04/2016
Voice call type Description
Broadcast
A special type of group call, which is received by all
terminals in the system (system-wide broadcast call) or
by a specific group. The originator of a Broadcast call is
usually a dispatcher. The receiving members cannot talk.
Quick Call
A special individual call configured on a soft key to
request help or information from a pre-configured
individual or talkgroup destination in a non-emergency
situation. Quick calls can also send status and position
reports. They can have a call priority that is different
from the calls normally set up using the PTT or the
Select/Send key.
Smart Call
A special individual call made in Smart Call mode which
allows you to make group or broadcast calls to specific
talkgroups without the need to notify the network about
the talkgroup change. Smart Call mode is initiated from a
configured soft key.
Smart call priority can have a call priority value from 0
(undefined) to 15 (pre-emptive priority 4, emergency) in
TMO and to a value from 0 (undefined) to 3 (Emergency
pre-emptive priority call) in DMO.

Note: Quick Calls cannot be made from a radio in Gateway Mode. Switch
your radio to TMO or DMO before making a Quick Call. See Direct Mode
Gateway on page 1
Note: Quick Calls cannot be made from a radio which is making or
receiving an emergency call or if your radio is in Transmit Inhibit mode.
See Emergency operation on page 33 and Transmit Inhibit on page 85.
Smart Calls
ASmart Call is a high priority group or broadcast call to a specific talkgroup.
This can be useful , for example, where you need to make an announcement
to everyone in the vicinity of an incident, not just those in your selected
talkgroup.
The radio supports two separate Smart Call Modes (A and B) associated special
folders Smart Call 1 and Smart Call 2 respectively. Each Smart Call Folder can
be pre-configured with up to 75 talkgroups.
You initiate a Smart Call by switching to Smart Call mode, then you press the
PTT to transmit to a chosen talkgroup in the Smart Call Folder.
Note: Broadcast calls cannot be made from a radio which is in DMO.
Attempting to make a Smart Call in DMO initiates a group call to the

Speech call settings
Note: The Speech Call Settings option is not available if your radio is in
Transmit Inhibit on page 85.
1. Select Menu >Groups > Speech Call Settings.
2. Select one of the options.
Modifying your call setup
Under certain circumstances, the type of a call which is being initiated by
your radio may be modified by the network or by the recipient of the call. For
example, you might make a group call, but the actual call being established
might be converted to an individual call to a dispatcher.
This feature is typically used by network administrators to provide centralised
control over certain services (e.g. customising all the radios so that Alarm
User Guide 69
Calls are all the same type and destination, allowing the network to decide
what type of call is made and the destination whenever an Alarm Call is
initiated).
When your call is modified you are alerted with specific visual and acoustic
alert indications, to make you aware that a new type of call is being
connected. The call continues as per any normal call of the new type, and the
icons and information elements displayed inform you about the type of the
ongoing call.
Once the call is established, the characteristics of the new call are the same as
those of any call of that type. For example, if the new call is half-duplex, you
need to press PTT before starting to speak, releasing the PTT allows other
parties to take the speech item, and the top microphone and half-duplex
loudspeakers are used.
Tip: When a radio is worn attached to your body, a half-duplex to full-
duplex call modification can be difficult to handle (since the latter is a
telephone-type call). To overcome this, your radio can treat the full-
duplex calls (resulting from a half-duplex call modification) as if they are
half-duplex calls, i.e. using PTT before speaking and releasing it to hear
the other party. (Making individual phone calls (full-duplex mode) on page
65.)

Paging alerts
The Paging Alerts feature allows the radio to act as a pager when it is in
normal operating mode or when you select a user profile which results in the
radio appearing to be switched off. (See User profiles on page 107.) The
Paging Alerts feature is triggered by receipt of a Status message which is
automatically displayed.
If there is also an associated SDS message to explain the reason for the Paging
Alert this is automatically displayed on the radio. If a call is in progress the
Paging Alert interrupts it. The SDS message is marked with an icon to
indicate that it is associated with a Paging Alert.
When the Paging Alert is triggered you hear a discordant two tone alarm and
the tri-colour LED flashes amber to indicate that a Status message has been
received. To stop the two tone alert press any key.

the Paging Alert.
User Guide 83
Networks
Authentication
Remote User Assignment (aliasing)
If your radio supports Remote User Assignment (RUA) using TETRA
Interoperability Profile (TIP) defined procedures and transactions, your
presence on the network requires authentication.
RUA allows you to be authenticated onto the network by entering a user
identity and optionally a PIN (maximum 7 digit). Once accepted by the
system, you can be addressed by your user identity, if aliasing is supported by
the system.
At the start of a shift, you can take a pool radio and, after you log in, other
radio users on the network can identify you by you user name. TETRA
services including individual voice and data (Status and SDS) communication
can be set up using your user name (provided your user name and your
corresponding user ISSI are in the Phonebook).
Caution: If you power on your radio using the Emergency button you
must log on to the network before an Alarm call can be initiated.
Note: Network log on/off may be initiated by your dispatcher.
To log on/off:
Your radio may be customised to request PIN entry log on to the network
when powered on. Alternatively select Menu > Networks > Log ON/OFF.
A screen appears:
Log On—enter you user ID and password then press Confirm.
Log Off—press Confirm.
Details—indicates the current log on state of the radio. and displays the
user's network identity.
84 SC20 series – 04/2016
Change Network
You radio may be customised to use other networks when you move into
their coverage area.
To change network
1. Select Menu > Networks > Change Network.
2. Navigate to the required network then press Select or the Select/Send key.
Tip: To select the local network automatically, select the Automatic check
box. (Pressing the Cancel/Home key does not deselect a network.)
Transmit Inhibit
Sometimes you may be working in areas that are sensitive to Radio Frequency
(RF) signals such as healthcare facilities. To continue operating your radio in
these areas, you can set your radio to Transmit Inhibit mode to prevent any
RF transmission.
When Transmit Inhibit is activated or deactivated, a status message is sent
confirming the operational state of your radio. You cannot activate Transmit
Inhibit when you are in a call.
Caution: Alarm Calls initiated in Transmit Inhibit mode are still
transmitted.
Note: You cannot select Transmit Inhibit if user profile Do Not Disturb is
selected. See User profiles on page 107.
Note: Your radio automatically leaves Transmit Inhibit mode when you
power it off; when powered on again Transmit Inhibit is not activated.
To activate or deactivate Transmit Inhibit mode
1. Select Menu > Networks > Transmit Inhibit.
2. Select Toggle to toggle Transmit Inhibit on/off.
When Transmit Inhibit mode is activated:
User Guide 85
The Transmit Inhibit icon appears in the Shortcut Bar as a notification or
the status line on the Home screen
The Tri-colour LED flashes orange four times approximately every 2
seconds.
Tip: There may be a soft key programmed to toggle Transmit Inhibit
on/off. For a list of programmed soft keys refer to the radio's Help (Menu
> Help).
Fallback Mode
If a base station loses communication with the rest of the network, then any
radios using the base station continue to operate, but with a reduced service.
This is known as Fallback Mode. The base station broadcasts the loss of
communication to all radios which are using it.
In Fallback Mode your radio can only communicate with other radios that are
registered on the same site: no inter-site communication is available.
When your radio enters Fallback Mode:
the radio status bar indicates Fallback Mode and the yellow warning
triangle is displayed momentarily
the Fallback Mode text box pops up in the centre of the screen for a few
seconds showing a customisable text message
the RSSI antenna icon flashes continuously
the tri-colour LED flashes amber intermittently (indicating limited service
mode)
the radio generates a warning tone
When your radio leaves Fallback Mode:
the radio status bar returns to normal (Ready… or similar)
the RSSI antenna icon stops flashing
the tri-colour LED stops flashing
a text box pops up indicating normal operation.
the radio generates a warning tone.
86 SC20 series – 04/2016
Operating Modes
Your radio supports the following operating modes:
In Trunked Mode Operation (TMO Mode) your radio operates on the
network infrastructure supplied by your service provider.
In Direct Mode Operation (DMO Mode) your radio can transmit directly
to another radio (antenna to antenna). In DMO Mode radio coverage
depends on the position of the caller and the receiving radio. When you
switch to DMO your radio leaves the network and tunes to the selected
DMO talkgroup. See also DMO Mode on the next page.
In Repeater Mode your radio enables two or more radios operating in
DMO Mode to communicate over an extended range, automatically
relaying voice and messages by operating as a repeater. See also Repeater
Mode on page 91.
To change operating mode from the Home screen:
Press the Menu context key, then select Networks > Operating Mode. Scroll
to the mode (highlight it) and press Select.
Alternatively, a soft key may be programmed as a shortcut to this function or
a shortcut may be added to the Shortcut Bar. Open the Shortcut Bar (in the
Home screen press the Shortcut context key), scroll to the Operating Modes
shortcut and then press the Select context key. You can then select the
operating mode.
User Guide 87
DMO Mode
In Direct Mode Operation (DMO), radios communicate directly with other
TETRA radios without using a network. The radios must all switch to DMO
and select the same talkgroup, and that talkgroup must use the same channel
(frequency). Communications to other users on the network are impossible
unless they also switch to DMO and select the same talkgroup.
Note: This means that in DMO, communications to the dispatcher is
impossible unless they also switch to DMO and select the same talkgroup,
or if they communicate through a DMO gateway (see DMO gateway
operation on page 1).
Group calls
DMO supports group calls (see Group calls on page 62) which are made and
received in the same way as radios operating in TMO. In DMO TETRA Alarm
Calls are either sent to the currently selected DMO talkgroup or (if
customised) may switch to TMO to make the call. If TMO is unavailable
Alarm Calls are made using DMO. See Emergency operation on page 33.
Individual calls
Your radio can be customised to allow you to make individual calls to other
radios working in DMO which are attached to the same talkgroup. In this
case individual calls are initiated by pressing the PTT key. See Making
individual calls (half-duplex mode) on page 64. (Individual calls to radios which
have selected different DMO talkgroups are prevented unless the DMO
talkgroups have the same carrier frequency.)
Your radio can also be customised to allow you to select a channel only
talkgroup. If you select a channel only talkgroup your radio cannot make or
receive group calls: it can only make or receive individual calls.
Tip: You can enable Presence Checking so that your radio checks
whether the receiving radio is available to receive when you attempt an
Individual call. See DMO options on page 90.
88 SC20 series – 04/2016
Using a DMO gateway
A DMO gateway (or gateway) is a device which allows users working in
Direct Mode to communicate with users in Trunked Mode effectively
extending the working range of a radio. When your radio is in DMO Mode
and it is in range of a DMO gateway the gateway icon appears and, if
customised, an audible alert is generated. You can now make and receive
group calls to TMO radios (and to the dispatcher) via the gateway. See DMO
gateway operation on page 1.
Note: If your radio is outside the range of a gateway, you may still be able
to hear the speech of another user who is in range of a gateway and who
is involved in a group call via the gateway. In this case the
Communication Mismatch icon is displayed to indicate that you cannot
take part fully in the call. If you attempt to respond to the overheard
speech, any radios within gateway range which can hear you also display
a Communication Mismatch icon to tell them that the speech is not being
routed via the gateway to TMO users.
Using a DMO repeater
You can extend DMO Mode range by using a DMO repeater (repeater). If
your radio detects a repeater the DMO Repeater icon is displayed and
your radio can communicate with any other radios in the selected DMO
talkgroup which are also within the range of the repeater. See Repeater Mode
on page 91.
User Guide 89
Note: If a radio is within range of a repeater but for some reason a call
cannot be set up through it your radio attempts to set up the call in DMO
Mode and the Communication Mismatch icon is displayed to all
members of the talkgroup to indicate that there may be members of the
talkgroup who cannot take part in the call.
DMO options
You can select the following DMO options:
Presence Check
Specify whether Presence Checking is performed before DMO Individual
calls are made. When Presence Checking is On your radio checks whether the
intended receiving radio is available and in radio contact before it attempts to
set up the call.
GW/Rep Filter
Specify whether your radio uses or ignores any gateway and/or repeater it
detects.
In the Gateway/Repeater Filter screen select one of the following options:
No GW/Rep—do not use any gateways and repeaters detected by your
radio
Use Repeater—Use repeaters detected
Use Gateway—Use gateways detected
Use GW/Rep—Use a gateway or a repeater detected by your radio.
Note: When option Use GW/Rep is selected, your radio selects the first
gateway or repeater that it detects. If it selects a gateway, a gateway
icon is displayed on the status line. If the gateway stops sending a
presence signal it will no longer be detected by your radio which may
then detect a repeater. In this case the gateway icon is replaced by the
repeater icon on the status line.
Therefore when you are making a call look at the display to understand
how it will be made. Take care if a repeater and a gateway are using the
same frequency and your radio is configured to use both devices (that is,
option Use GW/Rep is selected).
90 SC20 series – 04/2016
Repeater Mode
A radio acting as a repeater provides a service to other radio users. It extends
the range and enhances the reliability of Direct Mode communication
compared with basic direct communication between radios.
You can use a repeater to enable communication between radios which are
out of range of each other. The following diagram shows radios A, B and C
and a repeater which are on the same DMO talkgroup. A, B and C are in
range of the repeater. Because of its location, the repeater can pass
communications between A, B and C even though they are out of range of
each other.
You can also use a repeater to enable communication between two radios
which cannot communicate directly, perhaps because their users are do not
have line of sight with each other.
The following diagram shows radios A and B and a repeater which are on the
same DMO talkgroup. A and B are in range of the repeater. Because of its
location, the repeater can pass communications between A and B even
though they cannot communicate directly.
User Guide 91
What repeaters cannot do
In Repeater Mode the radio cannot:
make individual calls
take part in another group call
send status or SDS messages
use the Quick Status feature
edit text
use the phonebook
view the library of pre-defined Status messages
Participating in repeated calls
A radio in Repeater Mode may (depending on its customisation) operate
either as a Standard Repeater or as a Repeater with Call Participation.
Standard Repeater
If your radio is configured to operate as a Standard Repeater you cannot take
part in calls which are being relayed through it.
Repeater with call participation
If your radio is configured to operate in Repeater Mode with Call
Participation you can take part in the calls which are being relayed through it
if the call participants are on the same DMO talkgroup as you. To stop
participating in a call, press the Clear context key; you radio continues to act
as a Repeater.
92 SC20 series – 04/2016
Note: You cannot switch to Repeater Mode if the radio is in Transmit
Inhibit on page 85 or if the radio has initiated an alarm call (see Emergency
operation on page 33) which has not been cleared.
Caution: If you select Transmit Inhibit Mode while your radio is
operating in Repeater Mode, the radio leaves Repeater Mode and it stops
functioning as a Repeater.
Note: If you are going to leave a repeater unattended for long periods of
time, or as a permanent installation in a remote location, we recommend
that you configure it as required (select and attach the required Direct
Mode talkgroup) and then power the radio off. This will save the
configuration; each time the radio is powered on again, it will re-start with
the saved configuration. This will ensure that the radio is always running
with the correct repeater configuration even if it turns on unexpectedly
after circumstances such as power failures.
Switching to Repeater Mode
To switch to Repeater Mode see Operating Modes on page 87.
Note: Before you can use the radio as a repeater you must select a Direct
Mode talkgroup.
Changing talkgroups in Repeater Mode
You can change talkgroups while your radio is operating in Repeater Mode in
the usual way (see Talkgroups and folders on page 46.)
Caution: If you change to a different DMO talkgroup it may (depending
on the customisation) terminate any calls active through the repeater.
Using the Emergency Button in Repeater Mode
Caution: If you use the Emergency Button when your radio is operating
in Repeater Mode, any calls that are currently active through the repeater
will cease. When the Alarm Call is subsequently cleared, the radio may not
necessarily remain in Repeater Mode.
User Guide 93
Repeater states
A radio acting as a repeater can enter several states of operation, depending
upon the status of calls through the repeater and whether it has detected
other users of the direct mode channel. These states are reported as the
following top level screen messages:
Message Description
Ready: Repeater The repeater is ready and has no calls in progress
Busy DMO
Channel
The repeater has detected that the DMO channel is
being used. In this case repeater operation is
suspended.
In Call: Repeater A call is in progress through the repeater.

priority than Callout), and, if allowed, group calls to the Callout group.
You can only make group calls if PTT use is permitted during the Callout.
For some Callouts your radio can make and/or receive group calls to a
specially configured Callout group when it is in Protected Callout Mode. This
102 SC20 series – 04/2016
group may be the group the radio is attached to when the Callout is received,
or a different group which the radio is configured to connect to on receipt of
the Callout or when an acceptance message is sent.
While the PTT is pressed and the radio is transmitting the text “Talk” is
displayed in place of “CALLOUT” on the Radio Status Line at the top left of
the screen and no backdrop is displayed. When the radio is receiving a group
call the ISSI (or shortened ISSI) or identity of the transmitting party is
displayed in place of “CALLOUT” on the Radio Status Line at the top left of
the screen.
When the Callout has exited, depending on the customisation, the radio
either reattaches to the group it was attached to before receiving the Callout,
or remains attached to the new group.
Information Phase
Some Callouts do not exit after the initial acknowledgement is sent, but enter
an Information Phase when information may be sent to and received
from the originator of the Callout. Information can include a pre-set message,
a free-form text message or a Callout group call. Your radio can also be
customised to display a backdrop graphic to indicate it is in Information
Phase.
When information is sent (for example “Will Respond”) it is displayed and
the information sent icon displays.
Press the Exit context key to exit from the Callout or the Respond context key
to use an option on the Information screen or press a Left or Right
navigational key to display a menu of further options.
For some Callouts, group calls can be made by the radio to the Callout group
during the Information Phase if use of the PTT is permitted during the
Callout. See Group calls to Callout group on the previous page.
The options available during the Information Phase are Information, Accept,
Reject, User Response and Details.
Information
Send a pre-set information message. If only one Information message is
programmed in the radio you are notified by an informative message

Features
Your radio can be customised for various advanced features and can have
various soft keys assigned to frequently used features.
Privacy Screen
Your radio can be customised to display a picture when the screen is inactive
for a specified period of time. This helps protect the privacy of any displayed
information. This Privacy Screen feature is particularly useful if you are
wearing your radio at shoulder level. The normal display reappears as soon as
any activity occurs which turns on the back light.
View images
Your radio needs to be fitted with a microSD card if you need to refer to
images on your radio, such as maps, product diagrams or photographs, or if
you will be referencing WAP sites.
Tip: Image details are best viewed in Normal Text Mode. See Adjusting
text and icon size on page 42.
After fitting, images and WAP sites are uploaded to the card using Radio
Manager. During customisation the data is encrypted to prevent undesirable
viewing of the data by unapproved persons should the radio or card be lost.
Only JPEG images can be used with your radio and images must not excess 2
mega pixels.
Note: Your radio supports microSDHC 32 GB cards that must be
formatted for the FAT16 file system.
Note: The error No SD Card indicates that your radio is not fitted with a
microSD card. The error No Entries indicates that there are no files on

information about who to contact if that person is spotted, perhaps
advice on how to approach them and whether back up needs to be
called.
if the image was of a chemical symbol on the side of a tanker
transporting hazardous material, the comments could give advice on
what precautions need to be taken when dealing with the incident.
The date and time and other details are also shown.
Note: No details are available if the image has been loaded on to the
microSD card as a Bitmap.
5. To exit the image, press the Cancel context key.
Connector Protector
When working in salt water environments or in an area with high salt-laden
humidity such as sea mist or fog, enabling the Connector Protector feature

alert enabled then this is deactivated. See Whisper mode on page 37.
Lone Worker operation
This user profile activates the Lone Worker function to allow users working
alone to indicate that they are safe. See Lone Worker on page 112.
Group Focus
This user profile allows you to prevent any individual calls or group calls
from any talkgroup other than the selected talkgroup from being connected
to your radio.
Note: Any calls made to a radio which has Group Focus selected are not
recorded as Missed Calls.
Do Not Disturb
This user profile allows you to focus on an important task. It assumes you do
not want to be distracted by a call or alert on your radio. The profile sets your
radio so that no incoming calls are allowed except calls from the current
talkgroup (Group Focus above). Covert Mode operation is active. Audible
alerts are disabled. In this profile is selected you cannot select Transmit
Inhibit (see Transmit Inhibit on page 85

108 SC20 series – 04/2016
Man Down
Man Down is a licensed customisable feature which uses motion sensors to
detect motion in three dimensions. When your radio is powered on it stores
it's current angle of inclination (orientation). If it moves more than a
customised angle from the original inclination or is stationary for more than a
customised length of time, the radio sounds an alarm and displays a ‘Man
Down Alarm’ message. In other words the radio can detect conditions
indicating that you have become incapacitated. If you do not respond to the
alert within a customised time period, your radio initiates a Man Down
Emergency and takes action depending on its customisation.
Warning: Although Man Down is intended to increase the chances of
incapacitated users being detected, you should not regard it as a
substitute for compliance with appropriate risk assessment and other
safety procedures and practices. Do not entrust your safety to the Man
Down Alarm.
Warning: Test the Man Down Alert and Alarm regularly to ensure
they are functioning correctly.
Warning: Once started the Man Down Alarm sounds either until you
switch it off (see Cancelling false alarms on the next page) or until the
battery runs down. Ensure that the battery is charged regularly and
check that it has as much charge as possible before activating Man
Down.
Note: Man Down is disabled if the radio is placed in a car kit or charger.
Note: The Man Down feature may be customised so that you do not have
access to the following:
—the soft key On/Off toggle or a user profile to switch the feature on and
off;
—the Man Down screen to select the sensor or combination of sensors
used as described below.
User Guide 109
To toggle Man Down on/off:
1. Activate Man Down using one of the following methods:
Press a customised soft key to toggle Man Down on. The sensors
activated are those set in Man Down options on the facing page.
Select a user profile which uses Man Down (see User profiles on page
107). The sensors activated are those customised in the profile.
From the Home screen, press the Shortcut context key, then select the
Man Down icon.
A message (‘Man Down Starting’) is displayed and an alert sounds (a
succession of beeps).
2. Attach your radio in a comfortable wearing position on your body. When a
two second continuous tone finishes the radio’s ‘normal’ wearing position
has been recorded. An icon indicates that Man Down is switched on and
which sensors are active.
To deactivate Man Down, either select a user profile which does not use Man
Down, or press the customised soft key to toggle Man Down off.
Cancelling false alarms
If the active sensors detect a possible ‘Man Down’ situation the Man Down
Alert is sounded and a Man Down Alert message is displayed on the screen.
If you are safe (that is, this is a false alarm) you need to switch off the
alert, otherwise a genuine Man Down Emergency situation is considered to
have occurred and—depending on the customisation of your radio—various
automatic actions are initiated. For example, an Emergency Status message
may be sent to a pre-defined destination.
To switch off the Man Down Alert (false alarm situation):
press a designated key (which is different from the soft key used to switch
Man Down on and off) or
move the radio vigorously for a short period of time (if customised).
For example shake the radio up and down or sideways, or tap it, or (if the
radio is clipped to your belt) move your hips rapidly from side to side.
Note: After the Man Down Alert is switched off your radio may be
customised to start recording and storing the current position and/or
angle to use as the new ‘steady’ position.
110 SC20 series – 04/2016

GPS
If you radio is fitted with a GPS module it can obtain its position from GPS
satellites. The GPS functionality allows for both time- or distance-based
reporting.
The behaviour of the GPS function is highly customisable, both by
customisation and over the air from a control room application. Your radio
may also be customised to send position data automatically alongside TETRA
Alarm Calls or Status messages. The destination to which the GPS reports are
sent may be changed over the air. If your radio accepts a change of GPS
destination command it sounds a customisable tone and receives an SDS
message to inform you.
Tip: If customised, you can enable/disable the GPS function, see GPS
reporting options on page 124.
Tip: for the best GPS performance your radio needs an uninterrupted
view of the sky.
GPS position
To locate your GPS position

124 SC20 series – 04/2016
Bluetooth®
If your radio is Bluetooth enabled it can connect wirelessly to audio devices
such as a headset, or to one of many commercially available data devices over
a distance of up to 10 metres.
In order to use Bluetooth wireless technology your radio must first be ‘paired’
with a device. Pairing is the process which links two Bluetooth devices so that
they may communicate. Your radio may be paired with up to ten different
devices at any one time. A device only needs to be paired with the Sepura
radio the first time it (the device) is used. The pairing is remembered until the
device is deleted from the list of paired devices.
Caution: When you re-customise or update the software on your radio
the device pairings are preserved. Therefore, if the radio is being re-
customised and allocated to a different user with a different set of
Bluetooth devices, any unnecessary existing pairings must be manually
deleted before the radio is reassigned to the new user.
Caution: If you pair your radio in a public place, beware of
eavesdropping by unwelcome Bluetooth users.
Note: The Bluetooth Hands Free Profile is not supported.
Tip: If Bluetooth is not working, your radio may not be fitted with a
Bluetooth module and/or Bluetooth may not be a licensed feature on your
radio.
Bluetooth®on/off
To toggle Bluetooth on/off
Use one of the following:
User Guide 125
Press a customised soft key.
Select the Bluetooth option from the Shortcut bar.
Press Menu then select Options > Bluetooth > ON/OFF.
When Bluetooth is switched on but no devices are connected the Bluetooth
icon is displayed. The radio’s Bluetooth name, which is visible on data devices
when they attempt to ‘pair’ with your radio, is shown on the screen.
Audio devices
You can search for and pair an audio device with your radio or view which
devices have already been paired from the Devices screen. Once paired it is
possible to connect to or disconnect from a Bluetooth® device while a call is
in progress either using the Bluetooth® menu screens or a soft key
(disconnection only) if customised. It is also possible to connect to a headset
by pressing the button on the headset.
Tip: Before attempting to pair, check that the audio device is switched
on, is set to the discoverable (visible) state and is close to your radio before
attempting a new search. If several devices are available it is advisable to
switch off any which are not required and set only the required device
into the discoverable (visible) state.
Connect with audio devices:
1. Press Menu then select Options > Bluetooth > Devices.
2. Select Search.(Search is prevented if the Bluetooth® is switched off or if
the maximum number of devices (ten) have already been paired.)
126 SC20 series – 04/2016
3. If you are prompted to enter an Access Code, enter it as described in PIN
entry on page 132. If you enter an incorrect Access Code an error
message and a large cross are displayed and it will not be possible to
pair any devices with the radio. Correct Access Codes are valid until the
radio is switched off.
During searching a ‘Searching’ message is displayed and any data devices
found are listed. The search stops when all available data devices have
been found up to the maximum of ten, and a ‘Search Complete’ message is
displayed. If no devices are found a warning message ‘No Devices Found’
is displayed. To stop the search early and keep any devices found, press
Stop. (Press Cancel to abandon searching and delete any devices found.)
Tip: If a device is not found, check that the data device is switched on,
is set to the discoverable (visible) state and is close enough to your
Sepura radio before attempting a new search.
Any audio devices found are listed on the screen as they are found. Audio
devices which may be worn on the body show the headset icon and
non-wearable audio devices such as a car kit or similar device show the

User Guide 131
Security
Sometimes when you are working, you may need to secure your radio from
unauthorised use. The easiest way to secure your radio is to lock the keypad
when your radio is not in use. Your radio may be customised with other
security features such as PIN entry and a remote user network log on (to
authenticate network users).
Some radio users may need to enter secure areas and rooms within a building
or at a location, and your presence within these areas can be monitored using
the RFID tag in the radio and an RFID reader at the location.
PIN entry
You will need to enter the radio's 4 digit PIN at power on. Your radio may be
customised to allow you to change your PIN (see Change PIN on the facing
page).
Caution: if you incorrectly enter the PIN 3 times, the radio will lock. You
will then need the 8 digit Master Reset PIN (or PUK) to unlock the radio,
see Unlocking the radio after incorrect PIN entry on the facing page.
To unlock your radio:
1. Enter your PIN.
2. Press OK.
Tip: If you make a mistake you can use the Left navigation key to delete
the last digit entered.

PIN.
If you radio is customised to allow the PIN to be changed, select Options >
Settings > PIN Change.
End-to-End Encryption
If your radio shows the Secure Comms icon when it is idle, the selected
talkgroup is customised for End-to-End Encryption. In other words, calls you
make by pressing PTT are End-to-End Encrypted.
User Guide 133
Note: It is not possible to accidentally make a non End-to-End encrypted
call. Every talkgroup or individual subscriber that can be exempt from
End-to-End Encryption must be explicitly customised into the radio.
End-to-End Encryption is designed to provide maximum security for voice
and SDS communications, whether operating in Direct Mode or Trunked
Mode, irrespective of the security level provided by the network.
A radio that supports End-to-End Encryption may nevertheless be required
to make calls that are not End-to-End Encrypted. For example, calls to certain
talkgroups and individual subscribers may be customised to be exempt from
End-to-End Encryption. All telephone calls are also not End-to-End
Encrypted.
When dialling, a separate Secure Comms icon is displayed in the dial box if
the call or SDS will be End-to-End encrypted. During voice calls only (not
SDS calls) your radio my allow you to toggle End-to-End Encryption on/off
with a soft key.
When you are in a voice call, the Secure Comms icon indicates whether End-
to-End Encryption is operational. When the radio participates in a call that is
not End-to-End Encrypted, a periodic non intrusive audible alert is generated
(if customised).
When you receive an SDS (text) message or picture messages, if you see the
Secure Comms icon in the message details that the message was End-to-End
Encrypted.
Note: If the message ‘Security Check Fail’ is displayed while making or
receiving calls, it indicates that the radio has not been customised
properly. In such cases, please contact technical support in your
organisation.
Zeroising
Radios that support End-to-End Encryption are loaded with sensitive
cryptographic keys. To avoid a potential security compromise, you may be
able to delete (zeroise) these cryptographic keys if permitted by your
operational procedures.
134 SC20 series – 04/2016
Please refer to your Security Officer for details on how to zeroise your radio
as well as related operational procedures.
User Guide 135
Asset management
Handsets, consoles, radios and accessories are assets that need to be
effectively managed throughout their life cycle. In some organisations it is a
requirement to track assets and this can be done by labelling them.
Another method of tracking an asset is to use the RFID tag to track radios and
associated resources (persons and vehicles).
Asset management refers to the periodic maintenance of your radios.
Maintenance includes software upgrades and reprogramming of the radio to
ensure that it continues to meet your requirements.
Note: During programming the radio uploads information, such as the
State of Health of the battery which can also assist with auditing and end-
of-life strategies.
Labelling
The simplest form of asset management is to attach labels to your radios and
batteries. Self adhesive labels (those with an adhesive backing) are
recommended as they are easy to apply and commercially available, such as
3M™ Thermal Transfer Polyester label material 7815.
Your radio and Sepura battery provide an area for attaching an asset label.
Placing the label here will prevent it interfering with the way the product is
used.
Caution: Do not use solvent based adhesives. Always check the adhesive
used with the self-adhesives label.
Caution: Do not engrave any part of the radio. Engraving the radio's
casing may affect the compliance ratings and may invalidate the product
warranty.
136 SC20 series – 04/2016
Caution: Do not use paint, correction fluid or other forms of liquid or
aerosol to write or mark the radio or an accessory. Chemicals may affect
the radio's casing and invalidate the compliance ratings and product
warranty.
Place a label on the back of the radio in the label ID area above the carrying
aid attachment point as shown.
Alternatively, a label can be placed on the Card Compartment door recess,
but it must not interfere with the fitting of the battery or the opening/closing
of the card compartment.
Place a label on the battery in the Label IDarea.
RFID tag
Radio Frequency Identification (RFID) tags can be useful for asset tracking,
allowing you to automate audit tracking of pool radios, tracking radios in/out
of service centres and stock tracking. It is also useful for pairing pool radios
with resources (persons and vehicles) and facilitating the rights of access to
secure areas.
These tags allow devices to be tracked through a communications network -
when the tag with a unique ID is moved within the proximity of a RFID
read/write unit, it reads the stored data or writes data to the tag.
User Guide 137
Your radio has an integrated 'passive' RFID tag fitted, it is able to operate in
the presence of a RFID read/write unit, even when the radio is powered
down or has its battery removed. RFID tags operate at various frequencies—
the tag in your radio is preprogrammed to operate at a frequency of 125 kHz.
The range of operation is dependent on the RFID read/write unit.
Note: Read the Sepura document RFID in STP9000 Series Information Sheet
(Document no. MOD-12-1459) for more information and technical
specifications of the tag and read/write unit requirements.
How the RFID tag works in your radio
The RFID tag fitted into the back of the radio, its exact position is marked by
the embossed RFID logo. Hold the radio with the embossed RFIDtag within
range of the RFID read/write unit. The RFID tag operates in the presence of
the RFID read/write unit even when the radio is powered off or has the
battery removed.
Note: The distance between the RFID tag and read/write unit may differ
depending on the type of read/write unit being used. Always read the
instructions supplied with the RFIDReader on how to operate it.
Customising your radio
Your radio has a large number of parameters that can be customised using
the programming software tool, Radio Manager 2. These parameters are
grouped into a series of templates that can be easily modified to suit the end
user's preferences. A complete set of parameters for your radio is called a
customisation.
Radios can be customised either in bulk, by fitting them into a Sepura
programming pod which can accommodate 4 or 8 radios at a time, or
individually by directly connecting them to a computer running Radio
Manager 2 software using a Sepura Data/Programming Cable.
Note: Your radio cannot be programmed when Connector Protector on
page 106 is enabled.
138 SC20 series – 04/2016
Note: Your radio must be powered on and have sufficient battery charge
for the duration of the customisation process.
To program a single radio
A data/programming cable, with either an RS232 (D-type) connector or a USB
connector, is available from Sepura for customising a single radio.
1. Connect the USBprogramming cable to the computer.
2. Connect the cable to the radio by inserting the hook on the connector into
the slot as shown.
3. Secure the cable in position. Do not over tighten.
4. When programming is complete disconnect the cable from the radio.
User Guide 139
Accessories
There are various accessories available for your radio from fastening clips for
attaching the radio to clothing, to headsets and microphones that provide
hands-free operation. Only use Sepura approved accessories with your radio.
Sepura products have been tested to meet strict guidelines for personal safety
and operational conditions. The use of non-approved accessories may damage
the product, will result in the non-compliance with regulatory requirements,
compromise the product safety ratings, and will invalidate the product
warranty.
Caution: Some accessories may not work in close proximity of a TETRA
radio. When using USB and BT accessories, it is recommended that they
are worn on the opposite side of the body to the radio. It is the
responsibility of the service provider to ensure that appropriate EMC
testing has been conducted on accessories.
When your radio powers on and when you attach an accessory during
operation, your radio performs an authenticity check on any attached
accessories including the battery. If the accessory is not authenticated, a
message appears and the accessory should be removed.
Your radio has two connectors for attaching accessories. The rugged
accessory connector (sRAC) on the side of the radio is used for attaching
accessories such as a remote speaker microphone (RSM), headsets and
earpieces. At the bottom of the radio is the digital audio connector (sDAC)
that is used for attaching car kits, data accessories and chargers. It is also used
for programming the radio.
Caution: When using an RSM with antenna, it should be held a
minimum distance of 25 mm from the mouth.
Always refit the cover to the sRAC when an accessory is not in use.
You do not need to power down the radio before fitting or removing an
accessory.
