I also have a Caspian series integrated, and you can only power off when you use the rear rocker switch.Sen an e-mail to Roksan and see if they can help you with the manual or look at hi fi engine.
Need operating instructions for Roksan Kandy KA-1
I don't know how the indicator lights work on the Kandy KA-1 (not the L.III) integrated amp. Is seems that when the light is read, the unit is ready to play and that when it's green, it's on stanby??? Also, I would like to know how to switch the unit to "off" of "standby" without having to actually flip the rocker power switch at the rear of the unit.
