The Retekess T128 is a three-component wireless calling system comprising a T128 wrist watch receiver, a TD105 counter-mounted screen receiver, and an RF signal range extender — used together with T117 four-key call buttons. Customers press a call button at their table; the T128 watch and TD105 screen both receive the alert simultaneously, with the screen displaying up to four call records for staff reference. The system operates at 433 MHz without Wi-Fi or internet connectivity and supports up to 500 paired call buttons, with up to 999 channels available for numbering and configuration.
