Once locked, you can unlock the phone by repeating the procedure described on the previous page.

If you make a mistake when locking or unlocking the phone, the message CODE ERROR will be displayed. In this instance, start again from the beginning.

On entering the correct lock code:

–When locking the phone, the message LOCKED will be displayed, and will remain to remind you that the phone is locked.

–When unlocking the phone, the message UNLOCKED will appear briefly.

For other options, which provide more-selective restrictions, you may use the Call restrict function (Menu 14), page 43, or the Memory lock function (Menu 15), page 44.

System Select (Menu 1)

Each cellular service area can have two cellular service suppliers, called carriers. One carrier operates the ‘A’ system, and the other carrier operates the ‘B’ system (these systems are generally known as ‘non-wireline’ and ‘wireline’, respectively). Your phone is designed to work with both carriers.

This menu function allows you to program your phone for optimum operation when in your home service area or when away from your home area (this is called roaming). You may select any of the following roaming modes:

System A NAM	System B NAM
Selected*	Selected*
HOME AREA	HOME AREA	The phone uses only the
		home area and home system.

BOTH SYSTEMS BOTH SYSTEMS The phone uses either sys- tem A or B, whichever is the stronger signal.

HOME TYPE A	HOME TYPE B The phone uses only the
		home system.
NON-HOME	NON-HOME	The phone uses only the
TYPE B	TYPE A	non-home system.
