Remember, to make or receive any calls the phone must be
switched on and in a service area with adequate signal
strength. Emergency calls may not be possible on all
wireless phone networks or when certain network
services and/or phone features are in use. Check with
local service providers.
To make an emergency call:
1. If the phone 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 key.
If certain features are in use (call barring, for example),
you may first need to deactivate those features before you
can make an emergency call. Consult this document 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 phone 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.
Restricting Children's access to your Phone
Your phone is not a toy. Children should not be allowed to
play with it because they could hurt themselves and
others, damage the phone or make calls that increase your
phone bill.
