Plug any lamp into the Sonic Link Remote Receiver to receive alerts by flashing the lamp. Sonic Link's Pluglet (Plug-outlet) keeps your table uncluttered. The signaling lamp can also be used for normal room lighting with the lamp on/off switch. There is also an indicator light to remind you to turn on the attached lamp. This is a convenient system for deaf or hearing impaired users. This receiver works with all Sonic Alert signalers.
