General Troubleshooting Tips

Here are some general troubleshooting steps if your unit suddenly acts strangely with no clear damage or other reason for the change: First, ensure that you are using the correct power supply for your unit: is it the correct voltage, amperage, and polarity? (Note: voltage ratings should generally be matched exactly, but the amperage on the PSU can be equal to or higher than the device's required amperage, but not lower.) Next, check online to see if other users have reported a similar issue with this unit, as this will likely lead you to specific information about how best to deal with your problem. Finally, consult the manual or manufacturer's webpage for steps to either reflash or update the device's firmware, if applicable to your unit.
