If you are using AC power, check the outlet and verify that
the device is properly plugged in. Make sure there is power
available at the outlet. Make sure the AC power cord is
connected correctly to the power supply and the power supply
cord is securely connected to the device’s power inlet. If the
problem continues to occur, contact your home care provider.
Return both the device and power supply to your provider, so
they can determine if the problem is with the device or power
supply.
If you are using DC power, make sure your DC power cord and
battery adapter cable connections are secure. Check your
battery. It may need recharged or replaced. If the problem

supplied with your DC cord. The fuse may need to be replaced.
If the problem still occurs, contact your home care provider.
