Emergency calls may not be possible on all wireless mobile device networks or
when certain network services and/or mobile device features are in use. Check
with local service providers.
To make an emergency call:
1. If the mobile device is not on, switch it on.
2. Key in the emergency number for your present location (for example, 911
or other official emergency number). Emergency numbers vary by location.
3. Press the "Send" key.
If certain features are in use (call blocking, for example), you may first need to
deactivate those features before you can make an emergency call. Consult your
User Manual and your local cellular service provider. When making an emergency
call, remember to give all the necessary information as accurately as possible.
Remember that your mobile device may be the only means of communication at
the scene of an accident; do not cut off the call until given permission to do so.
