YOU decide who calls and WHEN - Never before has something like this been seen LooK>> Works with your telephone companyâ??s Caller ID service. Caller ID information is sent between the first and second ring on an incoming phone call. Depending on the mode of operation the call will either be blocked or allowed to ring your telephone. Block Mode: Disconnect Call This option will answer the call, emit disconnect (SIT) tones which make your phone look like it has been disconnected and then hang-up. Block Mode: Do Not Answer This option will prevent your phone from ringing, but will not disconnect them or emit the disconnect tones. To the caller it will appear as if your phone is ringing and you are either not answering or not at home. In Screen mode, your phone will only ring when the call is from someone whose number is stored in the Screen List, such as family and friends. Screen mode allows you to choose who can ring your phone. Numbers can be added to the screen list simply by pressing SCREEN while viewing the Caller ID display, later while reviewing the history list, or by simply adding the number in the Screen Menu. No more wrong numbers in the middle of the night or telemarketers bothering you during your private time. The device is fully programmable so the user can customize it to his/her lifestyle.
