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.
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 32). Keep your speaker audio volume to a minimum (see Adjusting the volume on page 29). Reduce the length of time the radio is transmitting and keep DMO or telephone type calls to a minimum because they cause higher current consumption. Shorten the GPS reporting intervals if enabled (see Reporting options on page 108).
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. NOTE: Do not charge a flat battery attached to the radio.
Using Sepura approved batteries When the radio is powered on, it checks the authenticity of the battery.

Talkgroups and folders 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. They are organised into folders to help you quickly select one that is applicable to your environment or situation. A folder can contain both DMO and TMO talkgroups, but only those talkgroups applicable to the current operating mode, either DMO or TMO, appear when a folder is opened.
Special folders In addition to the ‘standard’ folders created to contain your talkgroups, your radio can be customised with Special folders. Special folders can only contain talkgroups (they cannot contain folders). Some Special folders are continuously scanned, and when ongoing calls are detected you can join in by pressing the PTT.
Talkgroup Selection Mode When the radio is customised for Talkgroup Selection Mode, the selected talkgroup becomes the requested talkgroup to which you make calls. You can insert frequently used talkgroups in the Favourites folder, making it quicker and easier to change your talkgroup. Additionally your radio may be customised for Quick Groups that allow you to change to a frequently used talkgroup using a soft key. You can create your own user defined scan lists that are saved into the UDSL special folder.
Typical folder arrangement The following illustration shows how the folders can be used to organise talkgroups: Selecting a talkgroup You can use one of the following methods to select a talkgroup: From the Home screen, press Groups. From the Menu navigate to the Groups menu. Use a soft key to return to your Quick Group.

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). Adjusting the DMO power transmission level When you are operating in DMO, Repeater or Gateway modes, you can change the transmission power level that your radio operates at on the network. The radio operates at a normal transmission level which is predefined.
a text box pops up indicating normal operation. the radio generates a warning tone.
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 below.
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. 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 the facing page.
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.
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.
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.
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 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.
Callout alerts Your radio can receive Callout Alerts sent over the network to inform you of incidents. When a Callout Alert arrives the radio sounds an audible alarm and a Callout message is displayed on the screen. To silence this alarm press any key. A voice call may also be initiated. Your radio may also be customised to alert you of Callouts in other ways (such as vibrator alert and/or a flashing LED alerts).
Callouts requiring a response Some Callouts require a response. The following responses are possible: Accept Press Accept to indicate that you intend to act on the Callout (or select Accept from the pop-up menu displayed from the Left or Right navigation key.

the radio displays the Home screen, allowing you to respond to the call. You can still make a group call attached to a talkgroup but not a telephone type call whilst the browser is open. SDS messages If an incoming SDS message is received while the browser is active and the message is marked for immediate display then the browser will close and the SDS message is displayed.
Location Services Your radio may be customised and enabled for location services, such as GPS or other regional Global Navigation Satellite Systems (GNSS), that allows the radio to determine your location (longitude, latitude and altitude) and provides both timed- and distance-based reporting. The generic location services function on the radio is called 'GPS' and it provides support for multiple regional GNSS including BeiDou2.
Direction To read the direction in which your radio is travelling 1. Select Menu >GPS > Direction. The Direction screen gives information about the current direction and speed of travel. If the radio is stationary no information is displayed. However if the radio becomes stationary after a period of movement the direction information is displayed for five seconds to give you time to view it. Direction is reported in degrees from North.
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.
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.
Tip! If a device is not found, check that the data device is powerswitched on, is set to the discoverable (visible) state and is close enough to your Sepura radio before attempting a new search. The method of pairing the devices will depend on the Bluetooth® capability of the connecting device: Devices that do not support SSP will pair automatically if it has a passcode of 0000. If passcode entry 0000 does not work you are prompted to enter for a passcode. Enter the passcode and press OK.
Data devices You can pair your radio with data devices such as a laptop or PDA. When you pair to a data device it 'discovers' your radio. To pair with an incoming data device: 1. Press Menu then select Options > Bluetooth > Devices. 2. Select Discoverable. If your radio has been customised not to allow any incoming pairing operations ‘Cannot Add Device’ is displayed on the Devices screen. 3. If you are prompted to enter an Access Code, enter it as described in PIN entry on page 115.
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.
To edit a device name: Select Edit to rename different devices of the same type to make it easier to distinguish between them. To delete a device: Select Delete Device to delete the device from the list of paired devices.
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). 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 below).
To unlock the radio: 1. Enter your 8 digit Master Reset PIN. 2. Press Confirm or the Select/Send key. If you enter the Master Rest PIN incorrectly, you need to wait at least 5 seconds before attempting to enter the PIN again. If the Master Reset PIN is successful, the radio reverts back to the last known PIN. If you radio is customised to allow the PIN to be changed, select Options > Settings > PIN Change.
Updating E2EE keys End-to-End Encryption keys are automatically updated when the radio registers on the network when it powers on, and whenever the Key Management Centre (KMC) on the network broadcasts them. If E2EE traffic keys become outdated—which can happen in poor network coverage conditions— you can manually update them as described here. Manual key update is not supported on radios which rely on a Smartcard for E2EE.
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.
Place a label on to the Battery user label area. 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.
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. Your radio must be powered on and have sufficient battery charge for the duration of the customisation process. Your radio cannot be programmed when Connector Protector on page 96 is enabled.
There is also a Revert Non-Personal Changes option that allows users to reset the radio settings back to the last customisation, but keep their personal changes to the phonebook, talkgroups and messages. To revert the radio settings: 1. Select Menu>Options>Settings, then select the Revert User Changes option. 2. Select the option you require. Press the Select key. 3. Confirm the request to revert the radio settings to the last customisation. Press the Select key.
