For CS400 you must do factory reset: 1) Hold all 4 buttons (2 left side, 2 right side) down until "everything is illuminated" 2) then press and release left-down button and after that press and release right-upper button (it must be done fast, lets say in 1 second) 3) if you got service menu, then use right side buttons to navigate to "Reset to default". If no service menu, then repeat 1. and 2.
Hi Matty, This act just like a digital watch where you have to set everything your specification. What I'm understanding you can't activate the setting mode. If you press OK twice quickly then you have unlocked it.Did this work.........Joel
