To troubleshoot charging issues, ensure that the power source is functioning properly and that the RH1 device is correctly inserted into the dock. You should hear a charging notification when the device starts charging.

To further troubleshoot, please follow these steps:

1. Remove the RH1 from the dock.

2. Press and hold the power button for 3 seconds to check if the device powers on.

3. Check the battery level displayed on the screen:

- If the battery level shows 100% and this is your first time using the device, please note that this phenomenon is normal. We recommend fully depleting the battery before recharging it each time. During the initial charging cycles, the device automatically calibrates the battery, so after each full charge, the screen will turn off to enter power-saving mode.

- If this is not the case or if you encounter any other issues, please don't hesitate to reach out to EZVIZ customer support for additional assistance.

Regarding the overlapped map or if your robot always creates new maps, we recommend checking if there have been any changes in the environment or location around the base station, as this may lead to localization failures. Typically, a localization failure requires the map to be redrawn.

Please ensure that there is sufficient clearance on both sides of the base station to allow the robot to return to its charging dock properly. Additionally, we suggest deleting the new map and recreating it to see if the problem is resolved.

Moreover, please inspect your home for areas that could easily cause the robot to get stuck, such as the base of a fan. Robots often encounter difficulties in these zones. We recommend marking these areas as small no-go zones on the map.

If you need further assistance, please contact the EZVIZ support team for personalized guidance.

If you are experiencing an issue where the smart lock can be opened from the outside without using a fingerprint or passcode, please remove the front panel, rotate the square rod 90 degrees and try again. We recommend not securing it with screws immediately after installation; instead, wait until you have tested that all components are functioning properly before tightening it. If you still have further concerns, please contact our support team for further assistance.
