The Masimo W1 is a health and wellness watch designed to be paired with a smart device. This operator's manual provides comprehensive instructions for its proper operation, setup, and maintenance. It is crucial to read and understand all instructions, warnings, cautions, and notes before operating the device.

Function Description

The Masimo W1 system includes the Masimo W1 Device and a Masimo W1 Wireless Charger. When paired with the Masimo Personal Health app, the watch collects and displays vital sign measurements. The app also allows users to access care plan instructions from their care provider, and entered symptoms and collected measurements are sent to the care provider. The watch's Home Screen displays essential information such as Date, Time, SpO2 (when monitoring is enabled), Pulse Rate (when monitoring is enabled), and Daily Step Count.

Usage Features

The Masimo W1 features a user-friendly interface with a Menu/Back Button, a Home Button, and a Touch Screen for interaction.

Menu/Back Button: This button serves multiple purposes. Pressing and holding it turns the watch On and Off. When the watch is On, a single press cycles through menus from the Home Screen. In submenus, it functions as a back button, allowing users to navigate back to previous screens.
Home Button: A single press of the Home Button returns the user to the Watch Face. When on the Watch Face, pressing it once turns off the screen, conserving battery.
Touch Screen: The touch screen allows for intuitive interaction with the watch. Users can tap or swipe to navigate through menus, select options, and interact with various functions.

Basic Setup and Use:

Before using the Masimo W1, it needs to be charged and paired with the Masimo Personal Health app.

Charging the Watch: To charge the device, plug the charging cable into a power outlet. Remove the watch from your wrist and place the back of the watch onto the magnetic side of the charging cable. The watch will then begin charging.
Turning the Watch On or Off: To turn the watch On, press and hold the Menu/Back Button until the watch screen illuminates. To turn it Off, press and hold the Menu/Back Button while the watch is On until it powers down.
