BRRRRING! Now you'll hear when the phone ringseven if all your machinery is running. Or you're on the other side of the shop. The Universal Telephone Alert signals you loudly, in your choice of 4 sound patterns. Just plug it into your phone line, and set the volume at the level you need.
The device gets all the power it needs directly through the phone line. No need to carefully position it near an AC outlet. Or fuss with batteries. The whole unit is just 4" square by 2-1/2" deep, so it takes very little space whether you set it on your desktop or mount it on a wall. It's weatherproof, too. Hang it up outside, if you like, to hear the phone ringing from your lot or your yard.
You'll appreciate these features:
Loud electronic ringer — gets attention in noisy environments.
Volume control — lets you set the loudness.
Weatherproof case — works indoors or out.
Line powered — it doesn't require AC or batteries.
