Children
Do not allow children to play with your mobile phone since it contains small
parts that could become detached and create a choking hazard.
Emergency Calls
IMPORTANT!
This phone, like any mobile phone, operates using radio signals, cellular and
landline networks as well as user-programmed functions, which cannot
guarantee connection under all conditions. Therefore you should never rely
solely upon any mobile phone for essential communications (for example
medical emergencies).
Remember, in order to make or receive calls the phone must be switched on
and in a service area with adequate cellular signal strength. Emergency calls
may not be possible on all cellular phone networks or when certain network
services and/or phone features are in use. Check with your local service
provider.
Battery Information
New Batteries
The battery delivered with your phone is not fully charged.
Battery Use and Care
A rechargeable battery has a long service life if treated properly. A new
battery, or one that has not been used for a long period of time could have
reduced capacity the first few times it is being used.
• The talk and standby times depend on the actual transmission conditions
when using the phone. If the phone is used nearby a base station less
power is required and talk and standby times are prolonged.
• Use only Ericsson original batteries and the AC/DC adapter supplied with
your battery charger. Using non original Ericsson accessories could be
dangerous and the warranty does not cover product failures which have
been caused by use of non-Ericsson original accessories.
• Do not expose your battery to extreme temperatures, never above +60°C
(+140°F). For maximum battery capacity use your battery in room temper-
ature. If the battery is used in cold temperatures the battery capacity will
be reduced.
• The battery can only be charged when the temperature is between +5°C
(+41°F) and +45°C (+113°F).
• Turn off your phone before removing the battery.
• Use only the battery for the intended purpose.
