You don't have to worry about missing another important phone call when you use the Krown Ringer Amplifier with its flashing strobe light and extended ringer. This device for the hearing impaired connects directly to your telephone and wall line. It utilizes battery backup too so you don't have to worry about power outages or similar emergencies interfering with incoming calls. The backup requires three AA batteries, which are not included with the device. Backup works on the ringer with no power to the device, but it will not activate the light. This Krown product has an amplified ringer of 120dB and a strobe that flashes to alert you of incoming calls. The light uses an AC adapter for operating the on/off switch. Output on the adapter is 6V/1000MA. When the strobe is flashing make sure not to look directly at it, as this could hurt your vision.
The volume on the Krown Ringer Amplifier can be easily adjusted to high, low, or off. The tone can also be set to either high or low, making it easy to find the most comfortable setting for you. The ringer is designed to be heard over other noises in your home, and extends further than other ringers. The Krown Amplifier is an easy-to-install product. All you have to do is connect the telephone and wall lines to the respective jacks.
