•  Before updating, ensure that your watch battery level is above 50%.

• The length of time required for an update can vary depending on the network performance. Ensure that you have a stable 3G/4G or Wi-Fi connection.

• Over the air (OTA) updates require your phone to have a stable connection with your watch. The length of time required to finish the update depends on how long it takes to download the new version and Bluetooth transfer rate.

• After the update package is transferred through the Da Fit app, the wearable device needs to decompress and install the package. The update screen (with an upward arrow ) will be displayed on the wearable device. Wait for the device to restart after the installation has been completed successful.
