Fitting and Removing the Battery
Before fitting a battery please ensure that the SIM Card holder/Micro SD card cover is latched
shut. To fit, unpack the battery and slot it into the rear of the radio. Push the battery down until
the catch clips into the bottom of the case. The battery is fully secure when this catch has
clipped into position. To remove, push the catch upward towards the top of the radio. The
battery pack unclips and can then be removed.
Battery Charging
New battery packs must be fully charged before they are used. The battery should only be
charged using Sepura plc approved battery chargers. Failure to use an approved battery
charger may invalidate the warranty of the battery and the radio.
A range of battery chargers is available that allow the battery to be charged while fitted to, or
removed from, the radio (depending upon the charger model selected). When the battery is
fitted to the radio, the battery can be charged via the facility connector located at the base of
the radio. If the battery is charged with the radio switched on, the time remaining to charge
the battery to its full capacity is shown on the radio‟s display.
When charging, the colour of the tri-colour LED on the radio indicates the progress of battery
charging: flashing amber shows waiting to charge, amber shows charging in progress, green
shows charging complete and red shows charging failure. A fully discharged battery may not
provide enough power to support the display during the initial phases of charging. However,
when sufficient power is available, the display will operate.
Safety Precautions
Many professional and consumer products from cycle lamps to mobile phones and laptop
computers now use rechargeable lithium polymer cells because of their small size and high
energy density. When charged and used correctly these are reliable and safe. There are
some simple precautions that should be observed when charging and using Lithium polymer
packs. The precautions below apply to most/all Lithium polymer battery packs and chargers.
1. Properly designed Lithium polymer batteries and chargers contain effective protection
circuitry to safeguard the pack during charging and use, but in some very rare
circumstances of internal cell failure during charging, the protection circuits may be
