The Retekess T128-TD019 is a wireless call button and watch receiver system designed for table service environments. Customers press a TD019 call button; the paired T128 watch receiver alerts the wearer via light, vibration, or sound. The TD019 button includes a lanyard and silicone sleeve for flexible placement. The T128 watch must be paired with the TD019 buttons before first use.
