Features

• When a machine detects an abnormality, the transmitter sends a radio wave to a wristwatch receiver. The receiver vibrates for 5 seconds and displays a message for 10 seconds. Whether you're in a noisy environment or focused on a task, the receiver vibrates and communicates directly to your arm so you don't miss important messages.
• Ringing: Press the ringing button on the transmitter to send a message to the receiver.
• Infinite combinations and usage: Various combinations are possible by increasing the number of transmitters and receivers according to the management situation.
