Answer:
The K-H2 features two distinct operational keys—'Call' and 'Cancel'—in a 100% waterproof housing, allowing users to send an instant service alert and immediately cancel or clear the alert from the button itself.
Unlike standard single-button alert transmitters that require an attendant to reset the active alert at a central receiver panel, the SEWACall K-H2 integrates dedicated Call and Cancel functions directly on the transmitter surface:
- Call Key: Sends an immediate 433.92 MHz radio signal to alert station displays or portable receivers.
- Cancel Key: Transmits an immediate cancellation signal to clear the corresponding active call on the receiver, mitigating false alarms or accidental button presses.
Combined with its 100% waterproof design, the dual-key setup reduces unnecessary attendant dispatches across office cabins, restaurant tables, and clinic consultation rooms.
