Essential Info

Simple plug-in device connects to a phone line and a lamp. When the phone rings the lamp flashes. Great for the hearing impaired.

Just plug your lamp into the TR50, connect the phone line to the TR50 and plug the TR50 into an available outlet.

The TR50 is designed for one room signaling and is best used in rooms that will use a separate lamp for normal room lighting. The lamp plugged into the TR50 can only be used for signaling in one room because the TR50 does not work with other Sonic Alert remote receivers.

Works just fine with a light on top of Granny's TV. She doesn't miss calls while she's wearing headphones anymore.
