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.
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.
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.
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.
Push the safety latch on the bottom of the battery. Lift the battery upwards and remove.

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.
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.
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.
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.
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.
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 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.
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.
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.
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.
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 Ready: Repeater Busy DMO Channel In Call: Repeater Talk Repeater 94 Description The repeater is ready and has no calls in progress The repeater has detected that the DMO channel is being used.
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).

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.
Please refer to your Security Officer for details on how to zeroise your radio as well as related operational procedures.
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.
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.
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.
