Hi guys (especially davisneil ) Might seem like a stupid question, but why does the AC adaptor have to be connected to the player and plugged in when you connect the player to the pc? If i only want to send tracks over to the player, why do i need the charger connected as well? Maybe im wrong but i get the impression from the manual that u have to have the ac adaptor connected everytime you want to transfer tracks to the player. Im currently listening to the player while its charging from the AC adaptor, i have the usb connected to the player but not plugged into the pc at the moment because im not transferring anything. Please confirm or dismiss my assumptions PS) When unplugging the unit from the ac charger, do u unplug it from the mains first or just unplug the mini-plug from the unit first? does it matter?
