• Check connections between the Barricade, the
external power supply, and the wall outlet.
• If the power indicator does not turn on when the
power cord is plugged in, you may have a problem
with the power outlet, power cord, or external power
supply. However, if the unit powers off after running
for a while, check for loose power connections, power
losses, or surges at the power outlet.
If you still cannot isolate the problem, then the
external power supply may be defective. In this case,
contact Technical Support for assistance.
