TROUBLESHOOTING - I set my time on my cordless phone and when someone calls me the time changes to the wrong time. How do I stop this?
What is happening is by default your phone uses what is known as the Caller ID information to obtain the time. So when someone calls you your phone, it is being given the time that is being used by the phone exchange of the phone provider.
If you wish to avoid this from happening you need to change the time settings in your phone from "Caller ID" to "manual".
Go to Menu->Time Settings->Time Adjust. Change from Caller ID to Manual.
