The pulse oximeter features customizable alarm settings to alert users when readings fall outside predefined thresholds.

• Custom Alarm Function: Set specific SpO2 and heart rate alarm thresholds according to individual needs.
• Audible Alerts: The device will beep when a set threshold is reached (e.g., SpO2 below 90% or heart rate below 50 bpm). The corresponding value will flash on the screen.
• Volume Adjustable: The alarm volume can be adjusted.
• One-Click Mute: Quickly mute the alarm when it sounds.

7. Maintenance

7.1. Cleaning and Disinfection
