The Retekess T128-T117 is a wireless call button and watch receiver system for table service environments. Customers press one of the four-key T117 call buttons; the paired T128 watch receiver alerts the wearer via light, vibration, or sound. Buttons mount to tables or walls via double-sided adhesive stickers and the system operates at 433 MHz without Wi-Fi or internet connectivity. The T128 watch must be paired with the T117 buttons before first use.
