Solution
Plug the PT8051's AC cords into a suitable AC outlet. Then, turn on the PT8051
by pushing the on/off switch in the rear of the unit for both the main and rear
surround units.
Turn it on.
Unplug the PT8051 from the AC outlet briefly and then plug it in again so it will
reset itself.
The "+/–" buttons on the top of the PT8051 remote are the master volume controls.
Press and hold the "+" button to increase the volume.
Check that the cables are correctly and firmly seated on both the PT8051 and the
source equipment.
Be sure mute function is not activated.
Check that the video cable is connected and properly seated at both the PT8051
VIDEO OUTPUT and the TV input.
Select the correct input on the TV, the one that corresponds to where the VIDEO
OUT cable from the PT8051 is connected.
Turn it on.
It is normal not to have surround sound information present at all times.
Increase the REAR +/– level by using the remote control.
