Change Lock Code
The default lock code for your phone is generally the last four
digits of your phone number. It is advisable to change the default
lock code to a secret code for security purposes.
1. From The Security sub-menu, select Change Lock Code.
You’re prompted to enter the new lock code.
2. Enter the new lock code and press the OK soft key. You’re
prompted to re-enter the new lock code for verification.
3. Enter the new lock code again and press the OK soft key.
Your new Lock Code is stored.
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 32 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 number 911 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 calling
911 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.
