The Retekess TD019 is a single-button wireless call transmitter designed to pair with compatible Retekess watch or display receivers. Pressing the button sends an instant wireless call signal to the paired receiver. The TD019 must be paired with a compatible Retekess receiver before use — it is a transmitter only and does not include a receiver.
