Please check that the AC Power adapter is plugged in to the power outlet, check that the 12V connector is properly connected to the back of the CM-7500/DVR+. Make sure that the power outlet strip is switched ON. (If you are using a power strip)
The light on the DVR+ front panel will be 'dim' when in standby, and will be bright when it is 'on'.
If the problem persists, please ensure that there is power running to your outlets by trying another device in that outlet.
DVR+ power failures are rare unless there has been a power surge to your equipment. Common losses of power are faulty surge protectors or local power outages.
Note: we recommend that any power issues in your home are investigated by a fully qualified electrician.
