• 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.
