Setting the Time

This product allows for two methods of time calibration:

Method 1: Automatic Time Calibration via Mi Home/Xiaomi Home App

This product works with the Mi Home/Xiaomi Home app. Control your device using the app.

Download and install the app by scanning the QR code. If you already have the app installed, you will be redirected to the connection settings page. Alternatively, search for "Mi Home/Xiaomi Home" in the app store and download it. Open the Mi Home/Xiaomi Home app and tap "+" in the top right corner, then follow the instructions to add the device.

Once the message "Phone is connected" appears on the home page of the monitor's plugin in the Mi Home/Xiaomi Home app, the monitor will automatically calibrate the time.

* In Europe (excluding Russia), the app is designated as Xiaomi Home. The app name displayed on your device should be considered the default.

Notes:

• App versions may be updated; follow the instructions according to the current app version.
• If the monitor fails to add within 30 minutes of first powering on, reset the monitor or reinsert the battery before attempting to add it again.
• If "Connected to a Bluetooth gateway" is displayed on the home page of the monitor's plugin in the Mi Home/Xiaomi Home app, manual calibration is required on the settings page, as automatic time calibration is not available in this mode.

Method 2: Manual Time Setting

1. Press and hold the Up button on the right side of the monitor for 3 seconds until the "year" digits start flashing on the display, indicating that the monitor has entered time setting mode.
2. Pressing both the Up and Down buttons simultaneously confirms the current setting and moves to the next item. The display will sequentially show "year", "month", "day", "hour", and "minute".
3. You can adjust the values by pressing or holding the Up/Down button while the digits are flashing.
4. Settings are saved automatically. If no operation is performed for more than 15 seconds, the settings will be saved automatically, and the time setting mode will be exited.

Note: Information regarding the "day of the week" is synchronized automatically; it does not need to be entered separately.

Installation

Surface Mounting:

Remove the release liner from the holder and attach the holder to the back of the monitor as shown in the illustration. Place the monitor on a table, shelf, or any suitable flat surface.

Hanging:

Remove the protective film from one side of the sticker and attach it to the adhesive area on the back of the monitor. Then, remove the protective film from the other side of the sticker and attach the monitor to the desired location on the wall or other smooth surface.

Notes:

• Attach the monitor to surfaces that are suitable for double-sided adhesive tape. It is not recommended to attach it to dusty (e.g., drywall or concrete) or uneven surfaces to prevent product damage due to falls.
• When attaching the holder to the sticker or hanging the monitor on the wall, press firmly for approximately 10 seconds before use. Choose a height according to personal preference for the best viewing angle. The recommended installation height for the monitor is a maximum of 2 meters.
