First, make sure the charger is completely connected to the device and outlet properly. You may also need to test the charger with other outlets to ensure that the outlet is not the problem.
If the device still does not charge, connect your charger to another device to test that the charger is working. If this also fails, the battery may need to be replaced, please refer to [[Uniden Guardian G955 Troubleshooting|Uniden Guardian G955 Troubleshooting Page|new_window=true]]
