Video Phone Transmitter for All-In-One Alarm Clock System

Summary

AI-generated from vendor-published content · April 26, 2026

This small wireless transmitter plugs into a telephone or videophone jack and sends a signal to compatible Krown alerting receivers — including alarm clock units and bed shakers — when an incoming call arrives. It's designed for people who are deaf or hard of hearing and rely on visual or tactile alerts (flashing lights, vibration) instead of an audible phone ring. This is an accessory, not a standalone solution: you need at least one compatible Krown receiver (such as the KA1000 alarm clock or a bed shaker unit) already in place for this transmitter to do anything useful. The wireless range tops out at about 80 feet, which works well in a typical home but may fall short in larger spaces or across floors.

What Setup Looks Like

• Out of the box
  Plug the transmitter into your telephone or videophone wall jack and insert the included battery — it begins transmitting call signals immediately within range of compatible Krown receivers.
• With a guide
  
  1. Confirm your existing Krown receivers (KA1000, KA300RX, or bed shaker) are powered and within 80 feet of the transmitter.
  2. Position the transmitter near the phone jack and test by calling the line to verify the receiver triggers — adjust placement as needed. (Allow 15–20 minutes for placement testing.)
  3. See manufacturer support resources for detailed pairing instructions if the signal is not received.
