EMERGENCY CALLS
Mobile phones operate using radio signals, which cannot
guarantee connection under all conditions. Therefore you
should never rely solely upon any mobile phone for
essential communications (e.g. medical emergencies).
Emergency calls may not be possible on all cellular
networks or when certain network services and/or mobile
phone features are in use. Check with your local service
provider.
BATTERY USE AND CARE
We recommend that you fully charge the battery before
you use your mobile phone for the first time. The battery
can only be charged in temperatures between +5°C
(+41°F) and +45°C (+113°F).
A new battery or one that has not been used for a long time
could have reduced capacity the first few times it is used.
The talk and standby times depend on the actual
transmission conditions when using the mobile phone. If
the mobile phone is used near a base station, less power
is required and talk and standby times are prolonged.
Under normal conditions the stand-by time for this
battery is 155-300 hours.
• Warning! May explode if disposed of in fire.
