About the Sonic Alert Videophone Signaler: In the past two years videophones have become very popular for deaf people. Unfortunately, deaf people have had no choice but to buy a Radio Shack phone signaler for their DLink or Sorenson videophone. The only problem with the Radio Shack phone signaler is that it does not have a built-in transmitter to send signals to wireless remote receivers in other rooms. Deaf people will be thrilled and happy to learn about the new Sonic Alert Videophone Signaler because it is made especially for deaf people with a built-in transmitter to send signals to wireless Sonic Alert remote receivers in other rooms.
