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 37 ).
Keep your speaker audio volume to a minimum (see Adjusting the volume
on page 34 ).
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 GPS reporting options on
page 130 ).
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. 300-01852 and High Capacity battery
part no. 300-01853) 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.
