If you cannot control your Humax with it's remote control you should check that the remote control is in PVR mode. The PVR button should light up red whenever you press any other button on the remote control.
If either the TV, DVD or AUDIO buttons light up you need to press the PVR button once to switch the remote control to PVR mode.
If no buttons light up, or all 4 buttons are repeatedly flashing one after the other, you need to replace the batteries with some fresh AA batteries.
