• External power supply has failed or is disconnected.

 

• 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, or

 

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 your

 

distributor for assistance.
