Pressing the POWER remote control button switches the player to the Standby mode. In this mode the internal HDD (if installed) is turned off, as well as the video output, but the device does not switch off completely.
To activate the player from the Standby mode, press the POWER remote control button once again. The player will be switched on immediately (within several seconds). Note: you can also configure the player to power off completely when pressing the POWER remote control button (see Setup / Miscellaneous / Advanced / "POWER" remote button).
