Callers, Remote Access and Smart Ring.
How do I use it?
When you connect one of these PIN dependent features, you will be
allocated a temporary PIN (matching the last 4 digits of your phone number)
until you change it to a four digit number of your choice. You must activate
your PIN on your home phone.
Once set-up, you can change your PIN as often as you like. However, it can
only be changed from the phone service that your PIN dependent features
reside on.
