It uses the OOK modulation with a carrier frequency at 433.92MHz for signalling. It simply operates as below: 1. Pressing the “CALL” button to send a RF signal to a receiver or a monitor to make an alarm for normal help. 2. When the normal call is served, a “Cancel” RF signal can be used to reset the alarm by pressing the “R” button. 3. When the emergency call is activated by sliding the side switch down, an emergency signal is sent to the receiver or the monitor. 4. By pushing the slide switch up, it sends a reset signal.
