Lock Phone
Locking the phone blocks all outgoing calls except those to 911 and to the three
user-programmed emergency numbers. You can lock the phone manually, or set the
phone to lock automatically when turned on. In Lock mode, you can answer calls,
but you must unlock the phone to place calls (except to emergency and secret
numbers).
Important!: If you change the NAM1 setting after setting the phone to lock upon power-up and did not
program a number into NAM2, you won’t be able to access your phone. You must call the
Service Center to unlock your phone.
