Note: Your phone does not allow you to view the lock code for obvious
security reasons. If you change the lock code, be sure to write down or
memorize the new code.
Emergency #
Your phone provides the option of storing three
emergency numbers. Each number can be up to 20 digits
in length. All emergency numbers can be manually called
at any time, even when your phone is locked or restricted.
This can be a useful feature for controlling outgoing calls
from your phone.
Note: Emergency number911 is hard-coded into your phone. You can dial
this number any time, even when the phone is locked or restricted. If you
call 911 an audible tone is heard and an Emergency prompt appears in the
display for the duration of the call.
Important: Because of various transmission methods, network
parameters, and user settings necessary to complete a call from your
wireless phone, a connection cannot always be guaranteed. Therefore,
emergency calling may not be available on all wireless networks at all
times.
Important: DO NOT depend on this phone as a primary method of
calling911 or for any other essential or emergency communications.
Remember to always turn your phone on and check for
adequate signal strength before placing a call.
