The Krown Ringer Amplifier monitors a telephone line for incoming calls and flashes the bright strobe light to alert the hearing impaired that the phone is ringing.

The signaler features a louder ringer, up to 120 dB. The unit has two controls for the ringer; one that controls loudness and another to control the tone for a customized ringer.

It easily connects to, and is powered by, your telephone line. The strong strobe light is operated by the included AC adapter and a battery backup (requires 3 AA batteries, not included). The fact that it also works on a battery backup can be quite helpful, especially during massive blackouts and you are expecting a very important call.

PLEASE NOTE: This will work only with an ANALOG telephone line. This will not plug into and operate on a multi-line and/or PBX phone systems.
