You can put the ZVOX AV203/ AV201/ AV155 into the PS 13 setting for “No Auto On” which will defeat the AV203/AV201/AV155 from turning on automatically. If you put the AV203/AV201/AV155 in the PS 13 setting (display will flash “noAO” 3-times when selected), the unit will only power on with the power button on the ZVOX remote, or from the power button of a previously learned remote control. (PS 12 restores the Auto On setting, “AO” will flash 3-times on the display.)


To remove the Auto On feature press and hold the Other Settings button while the speaker is ON for 3 seconds and PS-0 will start flashing on the display, once you see that message appear release the button and tap on the Volume Up button until the LED reads PS-13. Once you see PS-13 it will flash 3 times then go away and it will read NoAO and you are all set.
