NAM Selection
The NAM Selection option lets you select your preferred system (NAM
1 or NAM 2), provided your phone has a NAM 2 number programmed
into it. (For more information, contact your Wireless Provider.)
Important!: If after setting your phone to Lock itself On Power Up, you change the
NAM Selection setting from NAM 1 to NAM 2, but there is no number
programed into NAM 2, you won’t be able to access your phone. You
must call your Wireless Provider’s Service Center to unlock your
phone.
System Select
The System Select option lets you disable (MetroPCS Only) or enable
(Automatic, default) your phone’s ability to roam (that is, automatically
select a network to use when outside of your Home Area).
Set Time
Use the Set Time options to set the current time and date displayed
on your phone and used by your phone’s Tools. (For more information,
refer to “Tools” on page 100.)
Note: In digital service mode, the Set Time feature is disabled. The network
adjusts time and date automatically.
With Airplane Mode set to On, the Set Time feature is enabled.
• Enter the current Date using your keypad:
– The month and day must be entered using two digits each.
– The year must be entered with all four digits.
