Humantechnik lisa RF telephone transmitter

The telephone transmitter for the Humantechnik lisa signal system recognizes incoming phone calls. As soon as you are being called, the telephone transmitter sends a signal to all receivers of your lisa signal system within its radio range. An LED display is used for transmission detection and as a battery warning light. The telephone transmitter is also equipped with a paging button.
 
The Humantechnik lisa RF telephone transmitter is available with two connection variants - galvanic (electrical) or acoustic. With the acoustic connection, the supplied, self-adhesive microphone is attached to the bottom of the telephone and connected to the wireless telephone transmitter with a cable. Alternatively, you can also connect the lisa RF telephone transmitter directly to the telephone socket using the telephone cable supplied (galvanic/electrical connection).
 
Please note: a signal system for hearing impaired people consists of at least one transmitter and one receiver! All system components of the wireless lisa series are fully compatible with each other.
