Emergency Calls
This phone, like any wireless phone, operates using radio
signals, wireless and landline networks as well as user-
programmed functions, which cannot guarantee
connection in all conditions. Therefore, you should never
rely solely on any wireless phone for essential
communications (medical emergencies, for example).
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.
