This cannot be done with the older versions where the power adapters of the parent unit and camera were different sizes.
- Switch between the power adapters of the camera and parent units.
- If that solves the issue, then the problem is with the power adapter.
- If the issue persists, please try to reset the monitor by opening the battery compartment, disconnecting the battery sack from the connection port, wait for 2 minutes and reconnect the battery.
If the issue persists, please contact customer support.
