- Test the connection by pressing the SOS button on the wristband. The receiver should alert.

Operating Instructions
1. Wearing the Wristband:
Wear the emergency call wristband comfortably on your wrist. Ensure it is not too tight or too loose.
2. Placing the Receiver:
Position the portable receiver in a location where the caregiver can easily hear or see the alert. Its portability allows it to be carried around the house or clipped to clothing.

In case of an emergency or if assistance is needed, simply press the red SOS button on the wristband. The receiver will immediately activate its alert.
4. Adjusting Volume and Alert Modes:
The receiver offers 5 adjustable volume levels and multiple alert modes (ring, vibration, colorful flash). Use the dedicated buttons on the receiver to cycle through volume levels and alert modes to suit your preference.

5. Mute Function:

Maintenance
