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.
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 connector at the base of the radio or place
the radio with battery attached into a charging dock. 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.
The battery may be charged separately from the radio using a battery-only
charger.
Fitting the battery
If a Belt clip or Shirt/Pocket clip is fitted to the radio, lift the Belt clip or
Shirt/Pocket clip before attempting to fit the battery. Do not attempt to
insert the battery into the battery compartment sideways under the clip.
This may result in damage to the radio and the clip.
6SC20 series – 07/2017

Quick Start Guide 7
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
Caution: Power off before removing the battery.

the battery.
