For added protection, unplug this apparatus during lightning storms or when unused for long periods
of time. In addition to disconnecting the AC power from the wall outlet, disconnect the signal inputs.

When the on/off power light is not illuminated, the apparatus may still be connected to the power
source. The light goes out when the apparatus is turned off, regardless of whether it is still plugged into
